The insulation you provided has warmed up the house markedly. The Penjerex that you added to the windows is also impressive stuff. It has improved the temperature of our living and bedrooms materially as well. At a fraction of the cost of double glazing but delivering the benefits that that solution provides, it is a great option (and the result is nearly invisible).
Thanks for doing this for us so professionally, your attention to detail and care for us and our property was the reason we selected you to do the work.
I’m happy for you to share this with other clients.
