I had been meaning to get in touch to say how impressed we were with your team. The guys were fun to have around – always smiling and friendly – and were also very helpful and professional. They did a great job, and we noticed the difference in the floors immediately even in this good weather, due to the sudden lack of draughts and the more solid, less echoey feeling of the floors. Please send on our thanks to the guys for a great job. 


We’re really pleased with the work and are now moving forwards with other plans to make the room warmer in time for next winter.


As architects, we used Devana for a Colchester project and the client was very happy with them.

We are very happy with the work Devana did, it is really refreshing to see a team with pride in their work. Actually hoping for a cold winter snap so we can really feel the benefit

The insulation has been great. Replacing the old tiled floor in the kitchen with insulation & LVT has meant we can actually walk on the floor in bare feet, even when it’s below zero outside and the kitchen is just so much warmer first thing in the morning. Same goes for the hallway which is no longer a cold spot which seeps chilly air into the living rooms. IMO, money really well spent! Thanks once again for such a great service.

My gas bill was about 20% cheaper than this time last year

We have now had December snow and January Ice and gales and am pleased to report how much better the house is since Joylon and Mark installed the roof insulation upgrade We are so pleased we had Devana do this project for us using cellulose insulation that was able to fit all the complex spaces.

We were really impressed with the professionalism of your two installers. They did an excellent job. I was very impressed the way they took time to protect our fixtures and fittings whilst they carried out the work so minimising any risk of damage.

We are delighted with the result and cannot praise highly enough your enthusiastic and hard working team. They are excellent ambassadors for your system, and remained cheerful even when faced with the steel tongues and extra time.
