Matt black roof

We had quite a specific need for our roof which required a good finish in matt black as it was a client facing film/photography studio.
The team worked swiftly and to a very high standard. We paid a bit more for the black idenden top coat but the finish really is first class.
I would thoroughly recommend Duratite and intend using them again for the remainder of my building

Commercial Project requiring circa 300m2 of insulating soffit spray (thermal and fire rated).

Richard and the team were a pleasure to work with, effective and swift communication throughout tender (pricing) all the way through to the delivery stage of the project.

Works on site were delivered quickly and safely which is always a must.

The O&Ms and warranties followed in a timely manner also, would definitely recommend and will be calling on my next project requirement.

Cavity wall insulation for air-source heat pump

I needed foam insulation for 60m2 of cavity wall as part of a project to install an air-source heat pump.
ThermoFoam were the most responsive of the three companies I approached. Of the other two, one responded after ThermoFoam had already finished the job. The other didn’t respond at all.
The ThermoFoam sales team were great to deal with and the installers couldn’t have been better. Carefully explained what they were going to do, did it quickly and efficiently, then tidied up thoroughly.
Good value too.
I’d definitely use ThermoFoam again.

Sprayfoam to new build house

Very efficient and organised company. Quoted clearly and quickly, booked in an install date and then were able to move it (twice) with no complaints when the rest of my build suffered delays. Ashley and his colleague arrived on the agreed date and were self-sufficient throughout, dealing with any minor niggles on site with zero complaints. After 4 days spraying the flat roof voids the site was left clean and tidy, including scraping the floor. I would not hesitate to use their services again.

Great company | Wonderful service | Top-notch workmanship

ThermoProtect installed under-floor insulation in our house. From the very beginning they were responsive and efficient. They did a great job informing us of any risks or changes in their plans. Andrew, the installer, was friendly and very clear in his instructions.

We turned to this company after a terrible experience with another company. The difference was like night and day.

I would highly recommend them.

Pitched Roof foam insulation

Really friendly guys, arrived on time, chatted through what they were going to do and how long it would take, were very informative about the product and also cleaned up after themselves (wasn't really messy anyway!) Disruption was kept to a minimum and we can already feel the difference in the house (was cooler over the weekend-we get direct sun and usually the house heats up like an oven) Would really recommend!

Well worth 5 stars +

So impressed with their service. From initial quotation, helping me with a grant application, the friendliness of the workers on the day. The work done was spot on and everything left neat and tidy. Great communication throughout. Just a quality of service you don't often find these days. I can't recommend them highly enough.

I would strongly recommend these guys!

I had quotes from two providers for roof insulation. Thermoprotect came in lower and were happy to do everything needed.

They organised everything, used highly experienced guys to do the work, they did everything perfectly, were wonderfully pleasant, cleaned up afterwards, and sent final paperwork across like clockwork.

In 40 years I've never worked with such an effective, efficient and friendly company. A credit to the industry and gives you hope that there are decent people out there! Bravo!!
