The london Loft and Kitchen Company
Rating: 4.5 out of 5
Extension Builder in Wallington
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

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

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.

Bathroom Fitting- 14 Mar 2025
My previous bathroom fitters did a very bad job with the bathroom and cloakroom toilet and left it unfinished. I am so glad I went with JM Building service as Joe and Martin completely transformed both rooms. They rectified the previous fitters errors and completed the rooms. Joe didn’t just rush through the job to get it done quickly—he took his time, ensuring every detail was finished to a high standard. He worked meticulously, making adjustments until everything looked exactly as it should, rather than settling for ‘good enough.’ His dedication to quality and precision was evident throughout, and the end result speaks for itself. As well as being very good at what they do, they are friendly, reliable, trustworthy and hardworking. I have already booked them in for another job and requested a quote for another. I highly recommend JM Building services for their professionalism and craftsmanship.

Kitchen Fitting- 12 Nov 2022
I am so happy with the work and professionalism of Tom and James. I had queried several companies and decided to work with G2 brothers based on how open and honest they were on the first visit for estimation of work. We discussed the work I wanted done, which was to replace the cabinets in the kitchen. We also discussed the budget I had and what the overall look I was going for. Throughout the whole project we discussed options, impacts and agreed together on next steps. They were a pleasure to work with, I will definitely use their services again. Great work!!!

Painting & Decorating- 3 Sep 2024
Great, reliable contractors. Had a full flat repaint job with some minor repairs (blinds fixing, handle replacement). Claudia was very efficient and responsive in communication. All was arranged pretty quick, appointment attended on time and kept to time schedule agreed. Had done a great job with repaint and provided reasonable rates. Also helped out with few minor repairs so I didn't have to get someone else. Very happy with the service , will certainly hire again. Thank you guys.

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

What experience do you have with similar extensions in Wallington?

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