Loft Insulation
Most lofts we go into already have insulation. It is just forty years old, flattened in the traffic areas and doing a fraction of what it should. Topping over the top of that hides the problem rather than fixing it.

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.”

“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.”

“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.”

“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.”

“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.”

“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.”

“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.”

“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.”

“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.”

What it involves
Insulation works by holding still air. Once it has been walked on, stored on or simply compressed under its own weight for decades, that air is gone and so is most of the performance, whatever the depth looks like.
So the first question at survey is not how much to add. It is what is already there, what condition it is in, and whether it is worth keeping.

What we usually find
Thin, uneven cover with bare patches along the joists. Old material squashed flat where somebody has been storing boxes. Two different generations of insulation laid over each other, the bottom one long past useful.
Cold upstairs bedrooms and condensation on the ceilings are the symptoms people ring about. The cause is nearly always one of the above.
How the job runs
Start to finish
- Free surveyWe look at what is up there, the joist depth, the hatch, the ventilation at the eaves and whether anything is being stored. You get a written price.
- The old insulation comes outCleared, bagged and taken away, and the roof space vacuumed before anything new goes down. Carpets and the landing are sheeted before we start.
- New wool laid to depthFirst layer between the joists, second layer across them so there are no cold gaps along the timbers. Eaves kept clear so the loft still breathes.
- Cleaned up and handed overCarpets hoovered, anything we moved put back, and your paperwork issued.

FAQs
The things everyone asks
How deep should loft insulation be?
Current guidance is around 270-300mm of mineral wool. A lot of the lofts we go into have 100mm from when the house was built, which is about a third of what it should be.
Why not just lay new insulation on top of 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 over buys you depth on paper and very little in the rooms below.
How long does it 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. We tell you which at the survey rather than on the morning.
How much mess is there?
It is filthy work, so we sheet the route from the front door to the hatch before anyone goes up, bag everything in the loft rather than dropping it, and hoover the carpets at the end.
Will it actually make a difference?
In a loft that is genuinely under-insulated, yes, and you notice it in the upstairs rooms first. If your heat is going out through single glazing or an uninsulated cavity instead, we will tell you that too.
Free survey, and a price in writing
No obligation, no doorstep sales. If we are not the right people for the job, we will tell you that instead.
