“Having benefited from Heatseal’s cavity wall insulation at our previous property, it was the first item on our to-do list when we moved house a couple of months ago. We have not been disappointed – the installation was straightforward (David is great!) and within a week our house was feeling much warmer. The insulation has saved us a fortune in heating and cooling costs over the years, as well as helping reduce noise pollution into the house – it’s a great investment.”
