Extensions- 27 May 2024
Disappointed- Avoid I hired EDSS Ltd for a full home renovation including loft, kitchen extension, driveway, outbuilding, and garden. The original project timeline was 17–19 weeks but extended to over 16 months, with several key areas still incomplete or unsatisfactory. While there were some changes to scope and delays (e.g. tenant moving out late), the lack of project management and missed deadlines became a major issue. There was no clear schedule, and expensive materials like kitchen and bathrooms sat unused for months, impacting warranties. Throughout the process, I experienced repeated requests for payments at inappropriate times, and there were long absences without notice, which delayed progress further. The quality of workmanship fell short in many areas. For example, drainage issues led to multiple visits from Thames Water, and I eventually had to hire another company to remedy after months of issues. A lot of work was left unfinished and needed to be outsourced.

I highly recommend William Haykal. We hired him to renovate our entire 2 bedroom, 2 bathrooms flat, he’s done the job in just 19 days and the end result is simply stunning.

From the initial consultation to the final touches, he made the process seamless and delivered outstanding results. I couldn't be happier with his work!

A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

Kamil and his colleague were brilliant and I’d highly recommend them. We had a ceiling crack that was bowing, Kamil correctly identified the issue and fixed it. He also sanded and primed our ceiling and walls, ready for us to paint. Kamil & his colleague worked really hard to finish the job in just two days and were polite and tidy. He was clear and considerate about the costs.
