I had difficulty finding a reputable tradesperson for external wall insulation on a solid wall. I chose an EWI specialist with many five-star reviews. After a site visit and a detailed quote from Sebastian, I trusted their professionalism. They completed the project on time, showing reliability, professionalism, and integrity. Sebastian was courteous, maintained excellent communication, and addressed issues quickly with expert advice. I highly recommend their services for rendering or EWI projects. Thanks to Sebastian and his team for successfully finishing the work on my property.

5/5 stars - Excellent quality and great professionalism
I couldn't be more satisfied with the external wall insulation work done by EWI in London. Sebastian, the owner, is exceptionally helpful and patient: he was always there for us, guiding us through our choices and answering every question with absolute clarity.
The site was managed to perfection, with work carried out to the highest standard, strict adherence to timelines, and an impeccably clean site upon completion. The insulation has made our house incredibly energy efficient, maximizing the heat pump and making it the ultimate energy setup.
A top-tier service that I would recommend to anyone!

We recently appointed EWI Specialist Ltd to carry out the External Wall Insulation works at one of our refurbishment projects, and we have been very impressed with both the quality of workmanship and their professionalism throughout.
The team worked efficiently, kept the site tidy, and maintained good communication from start to finish. The finished render is of a high standard, with a clean, consistent finish that has significantly improved the appearance of the property.
As the Project Manager, I found the team to be cooperative and responsive, addressing queries promptly and working with us to keep the project on programme.
I would have no hesitation in recommending EWI Specialist Ltd to anyone looking for a reliable contractor for external wall insulation works.

We honestly couldn’t be happier with the work! From start to finish, the whole team was incredibly professional, efficient and meticulous. The quality of the workmanship and attention to detail were outstanding, and everything was completed quickly without compromising on quality.
What impressed us just as much was the care they took with our home. Once the work was finished, everything was left exceptionally clean and tidy — they even carefully cleaned every single window to make sure there were no marks or stains left behind. That level of care really says a lot about the company and the people behind it.
The guys did an absolutely fantastic job and were a pleasure to deal with. We are genuinely impressed with the entire experience and the final result. It’s not often you come across a company that delivers such a high standard from beginning to end.
A fantastic team and a company we can recommend wholeheartedly and without hesitation. Thank you for an outstanding job — you guys absolutely nailed it! ⭐⭐⭐⭐⭐
