Plumbing- 19 May 2026
Emir did a good job. The company did a bathroom refurbishment after water leak, repaired the damaged ceiling downstairs and painted the room. Emir’s attention to detail is very good and he went the extra mile to do the job properly. I will recommend his services.

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.

Gavin and Luke built a single storey extension for us. It was quite complex and they had to remove several internal and external walls. They are very nice people to work with, genuine and honest, amenable. They were here for 9 months doing our work and we are thoroughly happy with them. They are very good - I would certainly recommend them.

Bathroom Fitting- 1 Jun 2025
I am really pleased with my new bathroom. I needed a partial refurb and new flooring due to a previous leaking shower. Landi did a great job fitting new taps, shower and sink in my bathroom. He was also able to advice me on the best sink and radiators and helped me to choose the right fittings when I was ordering. I didn't like the colour of the sealant and he redid it in another colour with no issues. He was efficient, friendly and completed the job in good time. Communication was always swift and I would be happy to recommend him to others and use him again for other jobs. Thanks Landi for great service.

We recently had our 3-bedroom house renovated, along with a new rear extension build and a garage conversion, and I couldn't be happier with the results. The team demonstrated exceptional craftsmanship and attention to detail throughout the project. From the initial consultation to the final handover, they were professional, reliable, and transparent about costs and timelines. The renovation completely transformed our home, enhancing both its functionality and aesthetics. The rear extension seamlessly integrates with the existing structure, creating a spacious and light-filled living area, while the garage conversion provides a versatile space we can now use as an office. The team was approachable, accommodating any changes we requested during the build, and always left the site clean and organized at the end of each day. I was particularly impressed with their ability to stay on schedule despite some challenging weather conditions. If you're looking for a dependable team that delivers quality work, I highly recommend Blueprint.
