The Insulation Corp

Jon did an excellent job installing insulation in my loft. From start to finish he was professional, approachable and easy to deal with. He explained what he was doing, gave helpful advice, and kept me updated throughout the process. The workmanship was first class and I would happily recommend him to anyone looking for reliable, quality work at a sensible price.

Great service, professional, friendly and top quality work. Highly recommend

Jon was very helpful and quick to respond! Did a good job!

Loft stairs repair

Jak was excellent from start to finish. 
Very responsive and gave regular updates. 
House definitely warmer now. 
Left the home spotless.
Nothing paid until all complete.
No hesitation in recommending. 

New loft insulation and 2 storage platforms

Jak and his colleague Ben have just finished insulting our loft and putting in elevated flooring above the additional insulation. They first had to remove well entrenched existing flooring and then add it. It took three days, and they were clean, efficient and polite, offering photos and clear communication about their work. Jak even pointed out some of my existing insulation was of good quality and that he could therefore reduce the amount of insulation I needed (and the cost).

Overall I was very pleased with their work and attitude. I'd recommend their services to anybody needing insulation

Great experience using The Insulation Corp. 

The team arrived on time as agreed, we're professional, kind and did an amazing job we are already using rhe new platform for storage and the house is already keeping the heat much better. Thank you to Jak and the guys you have made my wife and I very happy
