Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

Had work carried out by RS construction recently, was an overall pleasant and stress-free experience, had a dormant chimney breast removed all the way through my property. Which had to be removed due to constant leaks and repairs by previous roofers. Ross was very helpful and knowledgeable throughout the project and his team kept my house and garden very clean considering the work that was undertaken, it has not only freed space within my property but given me peace of mind concerning continuous leaks, which have caused numerous issues over the years. Can't recommend this company anymore , from sale to completion a very professional and helpful service

Conversions - General- 21 Jun 2025
Working with Petrit was a very pleasant and enjoyable experience. He and his team are friendly and open for discussions. They’re quick, affordable, and help with decision making. Would hire again! Have to say as well, as a woman, Petrit and his team treated my husband and I equally, unlike my experience with other tradesmen who direct all their conversations to the men. Petrit knocked opened up our living kitchen area, laid herringbone floors, replastered the property, installed new radiators, added a built in ladder to our attic, and re did our bathroom. He also helped us match the floor boards from an existing room and helped us source front and back doors for much better price than what we were getting quoted in East London. The painting of the entire house was done in a rush as we needed to move in, so the attention to detail fell down a little here compared to everything else that was done, but I wouldn’t hesitate to work with Petrit again!! After and before pics included!

Sagar and Sanjeev are incredible- they are very diligent and really well versed in what they do! They know what they are talking about and are very friendly and incredible to work with. There was no issue that they weren’t able to help me through when it came to a complete renovation, extension and garden landscaping of my house. They are experts in what they do and they’re the only contractors I want to work with for any other works in the future. Would always recommend them. 100/100!

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.
