My house was old and its condition was poor. Much were needed to be fix. The original kitchen layout were also inconvenience to my wife. I need to have all these changed under limited time. This builders have a team of specialists on almost every aspect. They gave me variety on the layout design and choose of materials. This saved me money, time and tons of trouble to find difference contractors. The after service and their respond time are very good too. I hope by sharing my happy experience can save your money and trouble to find a good contractor.

Extensions- 21 Apr 2019
The initial job was to complete a ground floor extension and house refurbishment. The job covered kitchen extension, underfloor and central heating, re-pluming, laying flooring, stair refurbishment, downstairs WC, patio, painting/decorating and much more then i can remember. I posted the job on Mybuilder and got several quotes from different firms. I was impressed with Dariusz as he requested the plans in advance of attending and provided a quote that was reasonable, before moving forwards I asked if I could see/visit a couple of jobs that Dariusz had completed recently which he arranged the feed back from ex-customers was excellent and the work was competed to a impressive standard. I was very impressed with Dariusz and his team, anything he was unsure of regarding the design he would ask before moving forward any surprises that cropped up with he dealt with, the team where clean and tidy. We are extremely happy with the work completed, guest that visit always mention the quality of the finish. I have recommended Dariusz to friends and family as well as use him for other jobs we have since planned. I would like to thank Darisuz and his team for all there hard work!

The london Loft and Kitchen Company
Rating: 4.5 out of 5
Extension Builder in Wimbledon
We are a southwest London Based loft and kitchen extension specialist. Our working area is very small with 90% of our jobs in Wandsworth and any work outside this area is never more than a mile or two away. With over 15 years experience in this area we know inside and out how these properties were built so when it comes to structural alterations you couldn't be in safer hands.

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

Extensions- 22 Dec 2022
Imran is a contractor who is personable and is trying hard, but at the end relies on different teams of builders to carry out the work. His knowledge of building work appears at time limited. In our case, this has often led to poor communication/hand-over, extensive delays and often poor (if not careless) craftsmanship. Very stressful. We now have builders (family business) finalising our project.

An extension builder in Wimbledon 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.

Your Wimbledon extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Wimbledon?

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