The Evergreen Workshop Timber Greenhouse Repair & Restoration Specialists Makers Of Hand Crafted Timber Garden Buildings

     Timber greenhouse repair is inevitable over time. For many gardeners and homeowners, the Cedar frame Greenhouse is the ultimate growing house. Timber greenhouses have been proven to outperform their aluminium counterparts. These beautiful structures also look more natural in the garden environment adding focus that the planting can be built around. However, after many years in the elements the frames start to suffer, glass starts to slip and break.

What if we could show you away to get the greenhouse looking better than the day you purchased it and even give you a guarantee for the whole structure for peace of mind.....

 

There are always plenty of people who offer an on site fix for garden building issues. Perhaps a liberal application of wood filler, some timber from the local DIY store nailed in, lots of plastic blocks and screws added before a liberal coat of shed paint is applied to cover it all up......

and they never GUARANTEE the building after they finish.

For most it's a year at best on the work they have done.

'Good from far - but far from good'

 

Sometimes the greenhouse looks to be too far gone and then it would seem that replacement is the only option

 

BUT Wait...there really is an alternative

What if it was possible to turn the clock back on your greenhouse.​ 

To make the greenhouse like new once again or even better....

Get rid of all the rot,  make repairs so that it will last for many years without issue. Better still, it will be easier to maintain with our simple tips and advice.

 

Don't be fobbed off with 'it can't be done,' or 'it's too expensive and not worth it.'

 

This is not some handyman short term fix. It is a full restortion of the greenhouse...... and its is always less than a like for like replacement , if not  we will and do say.

  • We do most makes and models
  • We provide accurate quotes and costings that we stick to.
  • There is no need for a new expensive greenhouse and installation costs.
  • There will be no expensive waste costs for disposal of the old greenhouse.
  • No need to lay that new base that most new models require.
  • PLUS IT IS better for the environment, 'save and reuse.'
  • THIS IS NOT A TEMPORARY FIX that will fail again after a few years. Once we restore your greenhouse we will guarantee the whole structure again for 5 years  and if you follow our simple maintenance advice and we will even extend that.

We do not use pictures of other people work. All the images on this site are of work we have undertaken. There are No 'stock images' or pictures 'borrowed' from social media.

Repaired and restored Gabriel Ash Greenhouse

 

Remember these are not 'temporary' repairs with cheap timber from the builders Merchants, there is no 'wood hardener and wood filler' and no thick coat of paint to fool you.

The natural oil finish clearly shows the wood and its condition. There is no attempt to hide behind thick paint.

The Greenhouse is repaired back to as it was manufactured but now finished to last much longer.

 

This is a C. H. Whitehouse ltd 'Heexalight' greenhouse, 

They are no longer in business so a replacement would definetley need a new base laid.

Now after restoration and again far cheaper than a replacement.

 

The client described it as 'like magic.'

The Alton Octagonal was the alternative to the Hexalight as with this rather rotted example.

Restored and located to another part of the garden.

The owner said they could never hope to afford a new one like this.

 

Fully restored Whitehouse greenhouse

 

Our system works, it really will be as new, not a temporary fix that will fail.

 

Here are a few images of the sort of previous 'greenhouse repairs' that we encounter. From DIY steel repair plates and incorrect timber choices to copious amounts of mastic or filler. Even concrete and mortar used as wood filler.....

Most failed again within 2-3 years and some within a year.

 

 

   Rather than a cheap fix or shoddy repair we look to restore the greenhouse back as it was originally. That way it not only looks good but will last for decades again.

     Here are just a few of the many comments we get when we return the greenhouses.

 

That is what we do...

             This is not a repair that might last a year or two.

    It is a FULL Restoration back to as it was the day it was delivered and we can do this to virtually any make of cedar greenhouse.

 

The amount of damage won't stop us, even when other say it 'CAN'T BE DONE'

Just look at this pair of Alton Amateurs, one from 1950s the later possibly 1990s.

Completely buried under brambles for years. discovered by the new owners whilst clearing the site.

If everyone else was to be believed these would be in LANDFILL now...

Not as now, the two stunning greenhouses that the owners are proud of and form part of their planned new garden design.

 

     

 

We have done this to scores of greenhouses, all different sizes and models. All saved from landfill and working again

 

Names such as Alton Greenhouses, Gabriel Ash, C.H Whitehouse and Halls are just a few of the many companies that for over 100 years have produced these cedar greenhouse frames, with many still working decades later.  They do hoever suffer with time and the elements.

Whilst Cedar is resistant to rot it is not immune, this is also true of insect damage as some think, 15 to 20 years is the typical life of the timber if unprotected. Over time the timbers natural resistance is lost and then the most common issue, wet rot a natural fungal growth, will attack the timber.

If Left unattended the rot, which is largely invisble will consume the timber and will spread out through the entire frame . The frames strength is lost, joints will fail. The glass will come loose and potentially break and ultimately the structure will collapse.

Poor repairs simply do not address this. They simply attempt to rectify a particular issue such as loose glass, whilst ignoring that the fungus is continuing on, causing more damage.

The fungus has very minimal needs essentially a host and moisture. So an old greenhouse with its moist humid atmosphere and our wet climate is ideal. The places you cannot see and treat are where it lurks and only when the damage is already done will there be any evidence.

 

We specailise in a program that erradicates the fungus and the damage it has caused in the timber frames. We then can repair the frames properly treat all the surfaces and coat to prevent moisture entering the timber and thereby restore the greenhouse to as new again.

 

See below how we can dismantle and fully repair / restore your old greenhouse frame back to as near new condition including glass and standard internal fittings. Before returning to site and re-erecting.

 

 

First we carefullytake down the entire structure, storing the glass and fittings

 

 

The frames are stripped down completely, every piece is seperated, checked and damage is identified.

 

 

All the old screws, pins and nails are removed. Most will have corroded and some will be almost be rusted away.

The first and a crucial stage that needs to be done is drying the frames. Remember WET ROT needs Moisture so frames repaired on site especially in winter months, will be wet and even with painting that trapped moisture will continue to feed the fungus for months.

 

We often see the mushroom growths from the fungus in the frames as the wood is being dried.

The fungus realises it is threatened and will look to send spores for another host.

 

Once the timber is dried back we can sort parts for reuse and machine new parts as exact replacements of the damaged pieces.

 

With all pieces restored or replaced the whole lots is treated with a timber treatment and then finished with a durable oild coating that will be absorbed and protect the timber. This is done before assembly to ensure 100% coverage

 

 

Once dry again the frames can be reassembled with new fixings.

 

 

The frames are then reglazed with the original glass that has been washed and set aside for reuse. Broken panes of course are replaced with new.

 

 

The greenhouse can then be returned and carefully put back up. The process is usually complete in 3-4 weeks.

 

The greenhouse is once again strong and stable. It for all intents and purposes will be as new again. NOW It can cope again with the Britsih weather like rain and storms. It is safe to use and ready to nurture.

 

 

All it needs now is the gardener...

 

  • Time on site 3-4 hrs to take away and 5-6 hours to re-erect, total time for restoration  is typically 14 -20 working days  (this is only a guide)
  • For most small commercial greenhouses we can generally travel up to 100 miles, even  to 120 miles at maximum and still complete the work, more than this is not practical. and often provide free quotes based on suppied photographs of the structure.
  • We unfortunately do not make spare parts for mail order for greenhouse 
  • We can usually supply costings and quotation from good pictures of the greenhouse we ask that you send over and can usually get a quote back over in 5-7 working days 

 

More examples in all sizes, shapes and age.

AND at a fraction of the cost of buying new.....

A common size cedar frame greenhouse is 8 feet wide and 10 foot long. (roughly 2.4M by 10M)

 

New as of January 2023 to buy a basic cedar frame greenhouse would be around £4200 to £5500 depending on specification, special offers. Installation and can be as high as £800 for some models. Fitments like benches are often an additional cost for lower priced models, in the case of an Alton evolution. installation is around £400 and shelves,  benches £720.

Then there is the cost of disposing of the old greenhouse and even laying a new foundation which for some is often required.

Most have to factor in a budget of £5500+.  As a guide we can often restore a 8x10 cedar greenhouse back to as new for around  30% less than a new like for like.

 

     In the case of this Alton Amateur 25 years old that had suffered flood damage and consequently rot to the base frames. The work took 3 weeks from collection to return and was left fully functioning all glass cleaned and intact and with all the rot removed ready for the new growing season total cost £3290

 

That was less than replacing even with a good quality aluminum greenhouse (prices as of January 2023)

Another favourite is the Alton Traditional 6x8 greenhouse, Perfect for small gardens or for where the focus is perhaps more on growing summer croops like Tomatoes and cucumbers. Here the owner was keen to restore the greenhouse so that he could spend time with his yound grandson sowing and planting.

The usual issues of extensve rot plus settlement over time causing glass to break all needed addressing. Like for like replacement cost was £4100 (plus disposal costs) The restoration back to as new was completed for £2900 (April 2025)

 

Even this very sad looking 40 year old Alton Amateur 8x10 with extensive rot through the frames and a lot of patch repairs over the years.

it was a much loved part of the family and they were keen to have it restored back again (August 2023)

 

 

 

Fully restored the greenhouse sits back in the garden it has serviced for so many years. Total cost was £3750

AS TO WHY RESTORE AND NOT BUY A NEW ONE CONSIDER, most Alton Amateur greenhouses for example are at least 15 to 20 years old and many far older before they develop issues. (We have worked on some well over 70 years old.) However because of the way the building is created with its sloping walls, it is naturally very strong. They can easily stand in exposed gardens battered by gale force wind, rain, snow and endure blistering summers. Many customers speak about the great storm and how there greenhouse survived when other aluminum models were destroyed They are perhaps the most succesful greenhouse design ever created, far better in design than most of their replacements.

      Their failure is sometimes in the quality of the material used when built, sometimes incorrect after care leads to issues. Of course there is our UK cold wet climate that also tesdts the structure and creates issues over time. However its repair / restoration along with treating all the original frame will once again produces a very strong and resilient greenhouse.  WE DO NOT CUT CORNERS ... Every piece of the greenhouse is taken apart and cleaned repaired or replaced...we call it a 'stick by stick restoration. 

Restoration means once again a strong, pleasing and fully functioning greenhouse again, There sis no expensive Upfront cost of a new structure, you avoid the cost and time required in disposal of the old greenhouse and potential costs of creating  a new foundation. It will once again look pleasing and continues to fulllfill the purpose it was intended and with little additional impact on the environment. 

 

 if you factor in all the costs then restoring your old greenhouse always makes sense.

 

Covering the South Coast and home counties (we will travel up to 100-120 miles to collect a greenhouse. Distances over this are often not cost effective.)

 

Note all prices shown are correct at the date shown but prices will vary with time.

 

Of course in some cases the original company may have gone out of business and so a replacement may be more challenging as with this unusual C H Whitehouse 'Hexa-Light' Greenhouse but we still aim to get them back in service.

 

The 'hexa-Light' was a hexagonal greenhouse made by C H Whitehouse, This one is about 35 years old and was in serious need of attention. Frames were completed rotted through and glass was literally falling out. but 10 days later it was back as original and ready to provide for the home owner once again. The company ceased trading in 2011 so a replacement to fit the extensive foundation built on a steeply sloping site was no longer readily available.

 

 

An Alton Amateur 8 repaired,  10 ft long in 10 days this one is 25 years old.

It helped that the client had regularily painted his greenhouse  and all glass was intact. A new greenhouse including removal of the old one, delivery and erection of the new one was costed by the client at over £3500. We completed the work for less than £2100 quicker than they could even deliver a replacement. (work undertaken March 2018)

Here is the clients reaction

 

Thank you very much for the excellent refurbishment of the Alton Amateur Greenhouse.
Your website stated that it would be as new and its is an accurate description.
WE are so pleased that we did not buy a new one and chose your company to refurbish the existing greenhouse at about half the cost.
Sue and David, Ifford
 

Every now and again you get to work on a project that means much more than just a greenhouse.

We recently restored a 16ft by 10ft Alton amateur purchased in 1972 by a family. Purchased after the loss of a family member the greenhouse had been moved from Sussex to cornwall and back via ashort stay in Dorset. 50 Years old and showing the signs of age we restored it back to as original and to see the family visit the greenhouse and their reaction was truly moving. But 50 years on the greenhouse lives on to support a remarkable family again.

 

 

The same principals apply to many greenhouses. Here an Alton Octagonal greenhouse weather beaten rotting and tired. This is the larger model 8ft by 6 ft

 

New model cost with installation is just over £3200 with the same spec. of accesories (Feb 2019)

 

Here the greenhouse is test fitted to make sure all the work has not altered the critical dimension.

Whilst ndergoing restoration all the timber is cleaned back, the fixings and screws replaced. All the old paint from an earlier attempt to improve it by the client removed and all rotted wood is cut out and replaced.

It is being modified to include more glass to ground level and extended upwards slightly to allow guttering to be fitted. This was not possible on the original 'as purchased' buildings. It is colour matched to blend in with the oiled finish. A new ridge cresting detail was also created

All the work plus the modifications is still over £1400 cheaper than buying a new replacement and delivered in 10 days which is quicker than it could be replaced with a new one.

 

                  Before and after in just 10 days

      More About Our Cedar Greenhouse Repair and restoration Work.

With all greenhouses they inevitably age and start to develop problems...                                              

Maybe you have an old timber greenhouse and the time has come for a decision to be made, Maybe the condition of the greenhouse is less than ideal... 

There are a couple of options available.

  • replace the building with a new one
  • Seek to repair the damage
  • Restore the greenhouse back to its original condition.

All of the above have merit. Perhaps a new buildings is required because it would be larger or smaller. equally minor repairs such as replacing broken glass can be made relatively easily. However as in the case of the greenhouse shown above some need a bit more work and only restoring them will return them back to the way they were when first purchased.

So what goes wrong ? What should i look out for?

Common issues with greenhouses.

 

Some common faults are rotting eaves rails, especially with the Alton Amateur grenhouse, this is where the roof meets the side frames. They tend to rot where the blocks that secure the glass in place are fixed to the frame.

 

 

 

Ground rails rotting away.

 

 

Frame timbers rotting especially around old steel fixings.

Water damage rotting away glazing bars. This will expose the screws or nails and ultimately the support will fail

Poor base preparation here has mean't the concrete kerbs are moving and the side frame is splitting apart

 

As the timber rots the buildings can take on a lean or start to loose their glass which rapidly accelerates the issues if not addressed. Here a main support brace that holds the roof has rotted at its end and the building is collapsing under its own weight

The results are clear from outside

This is the remains of a cedar greenhouse frame that has been attcked by woodworm and wet rot fungus.

This is looking down onto a side of a greenhouse where the wood is buried 12 inches 300mm into a build up of soil and rotting leaves. The base designed to keep the timber off the ground but it has no chance of working if soil and leaf litter builds up. Three is also ivy growing up the frame and as it does it splits the timber joints open.

 

Sometimes the failures are through poor maintenance and age but in some cases the issues are as a result of the way the greenhouse was built in the first place. The market place for wooden greenhouses is very competitive and manufacturers are constantly looking to cut cost to make the product affordable and protect profit margins. Inevitably these 'cuts' will impact on the durability of the greenhouse.

It goes without saying that you should look to buy the best greenhouse that you can afford. Be wary because there are lots of makers with 'interesting' claims about their product. One leading producer for example has a good guarantee for their workmanship but only a 5 year guarantee against the wood rotting !!!

It should be said that ALL the greenhouses used in the images above were restored back to as new again. Some took a little more work but they all went on to continue their role in the owners garden.

Is it better to Restore and not simply replace

We think so..         

Any timber building can be repaired or restored. Timber is environmentally friendly and its re-use doesn't create or add to polution. 

         Old timber tends to be slow grown and seasoned naturally over many years, Old timber greenhouses tend to be made from higher grades of timber than some of the more commonly produced models today. 

         The reality is that though the frame may be rotted in places, much will not be and most of the glass is usually intact. Damaged timber can be replaced and repaired.

         Consider that a new 10 foot by  8 foot cedar greenhouse today at its cheapest will be around £5000 with benches and shelves add £350 for its disposal and perhaps erection at another £500+. You will be looking to spend around £6000 to £6500.  We have always been thousands of pounds cheaper than this and your greenhouse will be like new again. Plus we can normally do it quicker than you can order and get a replacement erected

        of course you could pay to have it removed and install one of the many aluminum framed greenhouses now produced. At the flimsy end of the budget models we are looking at £800 - £1000 and they are certainly not comparable in looks and style to a timber greenhouse. Of course there are better quality aluminium frames and for a good quality make with a powdered coated frame you are more likely to spend £2500 to £4000 to replace it. We can often match even this price point.

|All we ask is that you look again at your old greenhouse and consider that It can restored.

 

Our Restoration literally involves taking the greenhouse right back to basics....

We have saved scores of greenhouses this way.....

 

 

This little Alton amateur greenhouse was inherited with a house purchase. The frames were so rotted we had to  tape them together to remove them from site but most of the glass was intact as was the unique Alton kerb stone foundation.

 

It went back as good as new set in a beautifully manicured garden

 

The clients reaction:

I recieved a phone call at work from my husband after you put the greenhouse back up. He said it was stunning, in all the years we have been married and all the work we have had done he has never done that. Believe me it is quite a complement from him.

Obviosly there are many factors in determining cost, Such as distance travelled, how much repair is required and if any changes are to be made. We often work from supplied photographs but can come and see the 'patient' and always try and aim to give a fixed quotation. A few more of the one we have done 

 

 

 

 

 

Here a lovely Alton Amateur Cedar Greenhouse measuring 8ft x 8ft

 

 

 

Fully restored and returned back to give many years service.

the clients reaction

We are actually in the process of moving and were going to leave it but now it's coming with us.

So before you condemn your old greenhouse, is it not worth considering getting it restored ?

There are many sites on the internet that say that after a while it isn't commercially viable to repair a timber greenhouse - most of these site also happen to sell new greenhouses, we don't take this stance and yes we do make greenhouses. 

              Most importanty it was ALWAYS cheaper than buying a new one if we don't believe that is the best course of action we will say so.

 

Here are just a small selection of some of the greenhouses we have brought back to life and what the client made of the experience.

 

This Client had tried four other companies who all said it was beyond repair...... It is a very large example of a C H Whitehouse greenhouse .

 

Inherited with a house purchase, The building was leaning so badly that the client refused to go into it.

However it was restored back to its original condition and even relocated in the garden.

 

The Clients Reaction:

Everybody else said it was beyond repair, we are so glad we found you, just to go inside and feel the warmth and space is special and the smell is amazing.

From very large greenhouses to more common smaller builds we have rarely turned one down and most restored at far less than the cost of a new building.

This standard 10ft by 8ft Alton Amateur was the proud property of a very keen gardener in his 90s

A tree bow had fallen on it breaking several frames and the ridge bar as well as most of the glass. Replacement was in excess of £2500 (May 2018) Repair and restoration of the roof and ridge was half that. 

The clients reaction:

When you said it would look like new i thought that was a bold claim...

                   but it has to be said you do not disapoint..

 

 

 

Another reaction:

 

It really does look like new again,

Is it still the original frame? it was all collapsing.

 

Of which the answer was at least 70% is.

65 Years old and just hanging on.

This Very old greenhouse had stood at the edge of a wind swept field for years The glass gradually being stripped off by the wind. Destined for the waste tip.......could we save it?

Of course we did,  plus The client wanted it to be moved into a new more exposed location and asked for a system that allowed them to easily change glass should it break. The solution was that we installed the glass with custom made hardwood blocks to clamp it in place these can be simply unscrewed to remove a pane of glass.

     Here the client had thoughtfully collected glass from other greenhouses and also supplied reclaimed oak boards that were used in the base. 

And the clients reaction:

Some would have simply walked away but you actually seemd to relish the challenge. It has been on this site since before our time and now will go on for many years to come. Now I actually have friends with 'greenhouse envy.'

Some of the oldest we have done are from the Edgelss's company. Generally they are 80+ years old. But still they can be made to look as good as new again as with these two example.

The clients reactions:

 greenhouse 1 : Who would have guessed that hidden in that derelict pile of wood was such a beautiful greenhouse.

 

Greenhouse 2 : I have always wanted a timber greenhouse, it was a small part of the reason we purchased the house. I just love my restored building and the neighbours still can't believe its the same building.

 

For every gardener their greenhouse is the beating heart of the garden and we are here to see it and the gardener thrive.
