  • Mr Mike
    The house looks like new. The team have done a great job. They were friendly and considerate at all times. EWI Specialist Ltd offers a very competitive price for 100mm of polystyrene insulation. Another firm asked for much more, for just 70mm of similar insulation. The system that EWI Specialist uses includes several finish layers on top of the polystyrene and the result is quite robust. Although occasional setbacks were encountered during the project, Sebastian accommodated unplanned demands with good grace, even though they cost him time and money. Working with him was such a positive experience. Part of the project involved cutting the cast iron Ventilated Stack (soil pipe), to realign it with the new wall dimensions. Cast iron can be brittle, but the guys confidently cut through it with no problem, using an angle grinder.

    We have really been impressed by services provided by EWI Specialist Ltd right from Quotation to Completion. We found you and your team to be very professional, courteous and caring. Above all, when we made changes to our original plans, you fitted those in without any issues. Having had the external wall insulation and other works carried out, our house is not only energy efficient but also looks very good now. We highly recommend your company to anyone. Thank you very much for your brilliant service.

    I have just recently had my house insulated by ewi. I must say they have done a fabulous job. Not only have I got the obvious saving to my heating costs and a noticeably warmer house, but the exterior also looks like new. The two Sebastians and their team spent a lot of time on getting the details right. They also listened very carefully to my requirements. The result was a stress-free job that turned out even better than I had expected. I highly recommend these guys.
