Spray foam
My lender has flagged spray foam. How fast can you move?
In most cases we can survey within a few days and give you a written price the same day. Removal is usually one to three days depending on how much foam is up there and how it was applied.
Why do lenders object to spray foam?
Two reasons. With foam in place nobody can inspect the timbers, battens or felt, so the condition of the roof is unknown. And foam sprayed to the underside of the roof usually seals the eaves, so the loft stops ventilating and moisture has nowhere to go.
Will removal damage the roof?
Closed cell foam bonds hard, so removal is slow physical work. Done by hand it comes back to sound timber. If the felt underneath has already failed we tell you at survey, not halfway through.
Can you remove just some of it?
No, and anyone offering to is not solving your problem. A partial removal leaves the roof partly uninspectable, which is what the lender objected to.
Do I get a certificate?
Yes. A Certificate of Removal, a written scope of works and dated photographs of the cleared roof. Nobody can promise what a surveyor decides, but that is what they ask to see.
Loft insulation and boarding
How deep should loft insulation be?
Current guidance is around 270–300mm of mineral wool. Many lofts we open have 100mm from when the house was built, about a third of what it should be.
Why not lay new insulation over the old?
Sometimes that is fine and we will say so. But if the old material is compressed, damp or full of debris, covering it buys depth on paper and very little in the rooms below.
Can I board over my insulation?
Not directly onto the joists. A joist is about 100mm deep and the insulation should be 270–300mm, so boards laid straight on top compress it and create cold spots. We raise the deck on legs instead.
How long does a loft take?
A straightforward loft is a day. If the old insulation has to come out first, or the loft is part boarded, allow a day and a half.
How much mess is there?
It is filthy work, so we sheet the route from the front door to the hatch, bag everything in the loft rather than dropping it, and hoover afterwards.
Damp
How do you know it is rising damp and not something else?
By looking outside as well as inside. A tide mark under a metre with salt staining behaves differently from a patch that tracks the weather, or mould that appears in cold corners. Those are three different problems with three different fixes.
How long before I can decorate?
New plaster needs to dry out properly, typically several weeks depending on the room and time of year. Painting too early traps moisture and it comes back through.
How long does a damp course last?
Our damp proofing work carries a 25-year guarantee, with the terms written into your quotation before you agree to anything.
Will the mould come back?
Not if the cause has been dealt with. If it was condensation rather than damp, the fix is ventilation rather than injection, and we will tell you that even though it is the smaller job.
Surveys, prices and guarantees
Is the survey really free?
Yes. No fee, no obligation, and no pressure to decide on the day.
How long is a quote valid?
30 days. It is fixed — everything included, nothing added on the day.
Do you take a deposit?
10% to book, with the balance on completion. Never on the doorstep.
What guarantee do I get?
10 years on workmanship, 25 years on damp proofing, issued within 48 hours of final payment. The terms are in the quotation before you agree.
What if you find extra work once you start?
We stop, show you, and price it before going any further. Nothing gets added to the bill without you agreeing to it first.
Do you cover my area?
We work from Manchester and Sevenoaks across England. Check the areas page or call 0800 870 8086.

What customers say
“We were in the middle of selling our house when the buyer's mortgage was declined due to spray foam insulation in the loft. From the first call the team were knowledgeable, honest and reassuring. The spray foam was removed professionally, the loft was left tidy, and most importantly we received full certification.”

“The team arrived and got straight on with the work, removing the old insulation and then straight on with installing the new. They were polite and answered questions we had, and when they had finished they cleaned up and asked us to have a look to see everything was alright. Very impressed.”
Carol O 10/10Loft insulation · PO12
“Great — quickly installed, friendly and super tidy.”
Ryan F 10/10Loft insulation · WF3
“We contacted EcoTrust after spray foam insulation in the loft caused problems with our house sale following the mortgage survey. They explained clearly why the foam was an issue and set out exactly what needed to be done. After completion we received the necessary paperwork, which was accepted by the surveyor, allowing the sale to move forward.”
Verified customer 10/10Spray foam removal · M2
“The 2-man team arrived just after 8am and immediately covered the stair and landing carpet prior to starting. They explained exactly what they were going to do, hoovered the roof space following removal of the 2 layers of old insulation, then fitted the new wool insulation and hoovered all my carpets. Friendly, polite and professional.”
Verified customer 10/10Loft insulation · CW11
“Really excellent job done. EcoTrust sorted out our damp porch area using damp course injections, salt neutralising treatment, a membrane as well as repointing and installing an air brick. It was plastered, left neat and tidy and ready for decorating. Liam's communication and advice was excellent throughout.”
Jess G 10/10Damp proofing · CW9
“From initial contact they were highly professional and very thorough with their initial assessment. Very professional and easy to have around the home. Communication was excellent and they even phoned if they were going to be a little late. Kept us informed at all stages and invited us up into the loft to check on progress.”
Verified customer 10/10Spray foam removal · BL5
“I would highly recommend EcoTrust. From start to finish they have been extremely professional. Booking in a survey was easy. Liam turned up on time, was very pleasant and informative, and gave me an instant quote which was very competitive. On the day the lads turned up on time, put down dust sheets and got on with the job in hand.”
Nigel B 10/10Loft insulation · BB10
“We had ongoing damp issues throughout the downstairs of our home. Ben and Lee were excellent from start to finish. They carried out repointing works externally to resolve the source of water ingress, then completed a full damp proof course and installed a damp proof membrane internally. Everything was explained clearly from the outset.”
Verified customer 9.33/10Damp proofing · M28
“No crappy selling technique, just the facts. Very understanding and helpful. They have done a great job at removing the spray foam and cleaning up after themselves as well. They hoovered everything — I think the loft is cleaner now than when they started.”
Verified customer 10/10Spray foam removal · CW10
“I used EcoTrust to insulate and board my loft. The two installers who carried out the work were wonderful — really considerate, helpful in their advice, and they cleaned up after themselves and worked really hard throughout. I would have no hesitation in recommending the firm to anyone.”
Verified customer 10/10Insulation & boarding · S36
“After recently having loft insulation replaced, EcoTrust came back to fix a hole in the ceiling and replaster. Ben and Lee were beyond any expectations we could have asked for. Being conscious of mess due to dogs in our home, they went above and beyond — there literally wasn't any. Would certainly use again.”
Simon R 10/10Ceiling repair · SY10
“Very professional. Team worked well clearing and cleaning the loft space prior to installing new insulation. They were polite and respectful and kept me fully informed throughout.”
Deborah T 10/10Loft insulation · WR3
“Polite and conscientious team. They worked hard and answered any questions we had. They took photos of the loft after they'd cleared it of boarding. After they'd put the insulation down they encouraged us to have a look. They vacuumed the carpet afterwards although they had put a polythene covering down to protect it.”
Valerie K 10/10Loft insulation · LS24
“Very happy with the work completed removing some stubborn spray foam insulation from our loft. Hard working guys, very polite and friendly. Always kept us updated on progress and timescales. A great job and would highly recommend.”
Verified customer 10/10Spray foam removal · DN14
“From when we had the survey to when the job was finished I can't fault anything. Everyone was friendly, professional and respectful to us and our property.”
Valerie W 10/10Loft insulation · WS2
“My loft space was partially boarded and the works had left it full of dislodged old insulation and debris. I got a call immediately after requesting a quote and a visit the same week. Two men arrived and got straight to work, hardly stopping for a drink. I'm amazed they managed to keep my house so clean when they were filthy.”
Verified customer 10/10Loft clearance · WN7
“Really impressed with the whole service. We had damp showing through the living-room wall and EcoTrust came out the next day. The explanation was clear and honest, and the team carried out the treatment quickly with no mess left behind. The wall has dried out perfectly and there's been no sign of damp returning.”
