Hard Flooring- 11 Sep 2025
I’m not happy with the job George did for me. Just a day the floor started moving. I contacted him and he cut the call on me like I’m a piece of shit. I am a sick single mum struggling. He took £2500 from me and the job is not good. I’m sad and disappointed in him.😭😭😭😭

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.

I have been a builder for the past 17 years. I started off with a building company, who specialised in building brick and flint, traditional homes. After the owner retired, and the firm closed, I branched out as a self employed builder 10 years ago. Over the last 17 years, I have carried out general building work, brick and flint specialist work, conversion, extensions, maintenance, porches, patios, lime work etc.

Lee put in a wooden porch at the front of the house for me. I was really impressed with his level of professionalism - always on time; replying to messages in a timely manner; started and finished work without any delays; and was always accommodating and polite. The job itself was completed to a high standard. I was pleased with the end result and would highly recommend Lee's services.
