Roofing (Pitched)- 10 Sep 2026
James was very prompt and gave a competitive quote and was professional in his response. Gave quotations for repointing a valley gutter and for replacing it if there was damage. James arrived promptly with his assistant and did a very good job with repointing the valley gutter as the valley itself was fine. He also replaced 4 damaged roof tiles at no extra cost. Would be happy to use Ridgewell Roofing for future roof work.

Extensions- 22 Apr 2019
Richard and his team have always been very hard working, respectful and professional throughout the project. We have had an extension, utility and bathroom/toilet renovation and we are very happy with the quality of work. It has transformed our home into a beautiful living space. Richard was very helpful when giving advice on materials we were choosing. The team were very accommodating to our needs, easy to work with and always tidied up after themselves. The payment schedule made it easy to keep on top of the budget and pay for any optional extras along the way. The building work was completed within the set timescale and to a high standard. We would highly recommend Lux for any building/renovation work.

Restoration & Refurbishment- 18 Feb 2021
Ray was an absolute professional. He fitted a new downstairs toilet which required a new soil pipe and associated groundwork as well as new stud walling to partition the space. He did most of the work himself, but brought in others for the pieces where he wanted an expert. He was flexible to small changes and was happy to take on additional work when unforeseen issues were discovered. The areas he had worked in were quickly cleaned before he left each day. Overall the work was completed to a good quality and at a reasonable price.

What qualifications and experience do you have as an extension builder in Raynes Park?

An extension builder in Raynes Park should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

What experience do you have with similar extensions in Raynes Park?

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 Raynes Park extension builder’s ability to deliver a result that meets your expectations.
