Noticably Warmer

My house looks amazing! Sebastian and his workers did an excellent job. They were all very professional and no bother at all. (You won’t have to worry about making tea and coffee all day, which is a real bonus)! The work was completed by various tradesmen, which meant they were each experts in their own field, and it was completed in the expected time frame. The Sebastians (There are 2 of them) were there to oversee the work from start to finish which ensured everything ran smoothly. My house is now noticably warmer and the damp problem I had appears to be drying up. I’m very happy. Thank you.

EWI Specialist team installed external wall insulation (Rockwool) and rendered the house for us and we are very happy with the work and would recommend without reservations; they were on time, professional, hard working and explained to us the process and answered the questions we had; we are complemented on the new appearance of our house regularly – how modern and smart the house looks now, insulation made such a difference to our single brick house – it is dry and warm in winter now. Job well done!
