Bricklaying- 17 Jun 2022
Our brick garden wall was collapsing and I contacted Richard Fitzgerald for a quotation. I'd already had a few quotes from other builders, some of whom had told me I needed work doing that didn't need doing! I found Richard to be trustworthy. He provided a competitive quote. He managed to source bricks that matched the colour of the adjoining wall, gave us a detailed breakdown of the work he would do, and didn't ask for any payment in advance. He built a strong brick wall with a concrete support wall behind. The finished wall is excellent and we are very happy with the work he and his team have done. On finishing the work the premises were left clean and tidy. I am very happy to recommend him.

Extensions- 19 Aug 2026
We paid for the build finished in Sept. 2025. Our concern is the foundations. The drawings specified about 1.8m depth and anti-heave boards due to clay and trees. The builder had not properly checked the drawings, then charged substantial extra for the depth. We paid, but the boards were not installed, and our photos and videos appear to show much of the foundation at about 1m. A replacement Building Controller declined to proceed without evidence of the boards. The patio, including £1,700 extension, was laid without proper excavation or a mechanically compacted base. Some tiles are loose and render is failing. Other faults include uneven floors and walls, falling plaster, catching doors, cladding gaps, poor electrical fitting, missing vents, a possible leak and unfinished items. Attendance was intermittent—about three weeks over two months—and the work felt rushed around other jobs. Our neighbour witnessed two workers urinating behind the shed. We cannot recommend this company...

What experience do you have with similar extensions in Wandsworth?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Wandsworth extension builder’s ability to deliver a result that meets your expectations.
