Matt did a fantastic job for us fitting a kitchen and boarding out the attic. He was professional, courteous and really helpful in figuring out how best to help us. He listened to what we wanted and really understood what we were trying to achieve. As a result we were very happy with the result and plan to use his services again in the near future.

Loft Conversion- 1 Aug 2025
Sami completed our loft conversion to a high standard, on time and within the agreed budget. He was respectful, supportive, and very knowledgeable. He offered helpful input and practical suggestions throughout the project. When I came up with ambitious design ideas that would have cost a fortune, he provided honest, pragmatic advice and suggested smart, cost-effective alternatives that saved us a lot of money. He communicated clearly, was easy to work with, and kept everything running smoothly. He also recommended trusted tradespeople when needed, all of whom did excellent work. In addition to the loft, Sami and his team completed other jobs around the house with the same high standard and care. I wouldn’t hesitate to recommend him — reliable, skilled, and genuinely committed to quality. A fantastic builder who takes pride in his work and delivers results you can trust. We’re absolutely delighted with everything he’s done.

Had an emergency when a pipe burst in the flat above causing flooding damage. Struggled to find a responsive option when I luckily game across Belgravia Property Solutions. They promptly inspected my flat, got me an estimate, and executed the works with a multidisciplinary team - walls plastered and painted, electrical repaired, floor recarpeted. Works were finished within one week of the first phone call. BPS will be my first call next time.

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.

Bathroom Fitting- 29 Apr 2023
Many thanks to Kris abd Kane on a job well done. Despite the very tight schedule, they completely refurbished our bathroom transforming it to a high-end (hotel standard) wet room. Kris's original quote was very competitive. There were extras, but these were very reasonable. Once the job was completed Kris actually came back to install 4 or 5 grab bars without additional cost. Kris, and Kane are both very easy to get on with; thoughtful and calm characters. I travelled abroad during the job; Kris contacted me regularly and responded promptly when I reached out to him. As with any job' there were glitches but Kris's solution focus approach ensured a good outcome. Hope to work with this company again.

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.

Extensions- 25 Jul 2023
Vini and his amazing team became part of our family for the months they were working on our house! Attention to detail and great communication was a top priority for me before starting our large scale renovation, and they delivered above and beyond on every front. Vini’s team helped transform my vision into a reality - they weren’t thrown or intimidated by any of my crazy/creative ideas, and were equally ready to advise and bring constructive ideas of their own to the table, based on their years of experience. We would highly recommend Olaj Brothers as trustworthy, professional and highly skilled tradesmen.

Monika, Mario and the team were excellent! Finished the job to a very high standard. Monika was all over the details and Mario was highly skilled and just got things done. Despite the project overrunning by a month or so (really not that bad vs target), we can not wait to work on another project with Monika again.

Conversions - General- 3 Jul 2023
We chose SWLBC to refurbish a two-bedroom flat. This entailed complete redecoration, replacement of the flooring with a new engineered wood floor, moving old and installing new electrical sockets and light switches, running some new piping and replacing the heating system with a more modern and efficient one. The quote from SWLBC was very competitive and we are really happy with the quality of the work. The flat is transformed and it looks terrific. Ben Toone who is the proprietor of the company is very professional and helpful. He was easy to contact and responded to our questions quickly and thoroughly. We met some members of his team during the works and they are hard working and competent. They also cleaned up the site beautifully after they had finished. Thank you Ben and your team. We are delighted with your work and highly recommend SWLBC.

What to ask a Stockwell extension builder before hiring?

Before hiring an extension builder in Stockwell or extension building company in Stockwell, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Stockwell 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.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Stockwell?

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

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Stockwell extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
