Dyson did the cavity wall insulation…
Dyson did the cavity wall insulation for our house this week - it was at zero cost to us (under the grant) and they did a fantastic job, fast and efficient. It turned out there was a small issue (our damp barrier was a brick too low) but Dyson came up with a good work around (they relaid the block paving closest to the house to give a drain-away, with gravel) and they did that with no fuss and no extra cost. The team were professional and polite and I was very impressed with the look. Thank you!
