Latest review:
We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.

Conversions - General- 30 Jul 2019
offered me useful advice related to the structural framework of my bay window which was in question as it had moved away from the building ever so slightly. Very responsive and communicated well which is what you want from a tradesman. I asked for additional work to be carried out that included sealing bathroom worktop, sanding down and improving the surface together with cutting out a peice of wood to make my boiler more accessible. This was completed to a neutral standard as the finish I was expecting was to be better with a cleaner finish also. Overall the job was positive, thank you very much.

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.

Bathroom Fitting- 15 May 2017
We hired Inside/Outside to re-do our bathroom. New sink, bath, toilet, tiles, lower ceiling, re-hang the door and move the radiator. They were polite, honest, professional and very hard working. When they came round to quote they were noticeably more thorough and showed more attention to detail than others. Their quotes were very competitive, their work was good and they removed all the rubbish as well. They also came back afterwards to check everything was working and to deal with a couple of 'snags'. We will be using them again.

After a previous contractor took our money and left our loft extension unfinished, we were devastated and worried about how we would ever get our home back to normal. Then Lewis from Lebelle stepped in and completely turned things around. Lewis was patient, understanding, and incredibly professional. He worked quickly, kept costs under control, and finished the loft extension to a standard we’re so happy with. The stress he took off our shoulders was unbelievable. We honestly can’t thank Lewis enough. If you’re looking for someone trustworthy, skilled, and genuinely caring, Lebelle is the company to call.
