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.

Bathroom Fitting- 6 Mar 2026
What a great team! Muneeb and his team finished the job in time, turned my tired old bathroom into a wonderful new space. Price quoted was half what we were being quoted by others. Muneeb just focused on this job rather than many others who leave the customer waiting whist doing multiple jobs. All materials used are top quality and nothing was too much for him. Muneeb kept variation minimum and agreed details in advance. Thank you Muneeb and team

Groundwork & Foundations- 7 Feb 2026
Oli carried out the groundworks and demolition at my property and was on site every day with his crew, fully committed and hands-on throughout the job. I am an architect, and this was work on my own home, so my expectations were high. Oli met those expectations fully. He has a strong knowledge of groundworks and demolition, works carefully and methodically, and you can tell he genuinely enjoys what he does and takes real satisfaction in delivering the work exactly as required. He was always in a good mood, easy to communicate with, and a pleasure to have on site. I enjoyed discussing the project and hearing about other jobs he has completed over his 23 years of experience, which clearly shows in the quality of his work. I would highly recommend Oli for any groundworks or demolition works.

Artan and his brother built a shed concrete base in our back garden that is located on a steep ish hill. They are professional and polite, and Artan went over and above to ensure delivery of materials was resolved due to our road being a little challenging for an inexperienced lorry driver. They’ve done a stelar job and we are very pleased with the end product. We are planning to use their services in the near future for other works.

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.

Bathroom Fitting- 26 Feb 2026
Worst job ever. The first day he came at 10.30am started the job left at 9pm said it would take a day & a half. The next day he said he would be here at 8.30am again he came at 10.30am & his words were I’m going to finish in 2 hours maximum. By 3pm he still hadn’t finished & I heard him speaking to someone on the phone saying that he would be there in 45 minutes.then he told me he needed a part for my job & he would be a couple of hours, he came back 4 hours later without a part.Again he was here till 9.30pm. He said he had finished. I went to look and his work was bad. I complained he said he would come back the next day. the next he said he had finished & I told him I wasn’t happy he came back the next day. He tidied up his mistakes.he shaved the bottom of the door off a bit as it wouldn’t close coz of the new tiles & he left, as he was leaving he said please give me a good review. I said I’ll tell the truth & he said but the truth isn’t good. He didn’t stick the threshold back on.

Restoration & Refurbishment- 31 Aug 2020
It was a pleasure dealing with Peter and his team from start to finish and we couldn’t be happier with the work that they did. I was impressed with Peter’s previous work and we developed a good rapport from the first meeting and I felt that I could trust him with the work. He was clear about the detail of the work that needed doing upfront and his quote was itemised to reflect what each element would cost. The work was done on time and of a high quality and Peter was responsive at all times to any questions or concerns we had. He also made great suggestions of how we could do things better and was open to our ideas and realising our dream. His team were punctual, friendly and took care of the house ensuring the work that they did was of a high standard at all times and attention to detail which really has made a difference now that the project is completed. I wouldn’t hesitate to recommend Future shapes to anyone and would certainly use them again.

What to ask a Kilburn extension builder before hiring?

Before hiring an extension builder in Kilburn or extension building company in Kilburn, 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 Kilburn?

An extension builder in Kilburn 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?

Your Kilburn 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 Kilburn?

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 Kilburn 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 Kilburn 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.
