Extensions- 22 May 2019
Jacob was very accommodating and flexible. His team were great and he completed the work nicely. There was some splatter from the cementing on to my neighbour's wall. He tried to clean it off but it wouldn't all come off. Therefore, he went out and bought some paint and repainted their wall. I would get him back for more work without hesitation. When looking for a builder - they have to be honest, work hard and to an excellent quality without cutting corners. They should be responsible to ensure neighbours property isn't damaged and provide consultancy as what we want and want is realistic can differ significantly! - and if any issues rectify them once the job is complete and of course provide good after sales. I have used several builders over the years - very few tick all of the above boxes. Jacob certainly does.

Windows & Doors (uPVC & Metal)- 28 Jan 2026
Very unhappy with how things went with Angle Construction overall. Poor comms during the transaction was the first red flag - no communication for 2 days the moment money was sent, however afterwards received an apologetic call - parts ordered and arrived in due course. Andrei turned up, and got to work on removing the old gate, but then started shaving down the post without saying anything -we were told after that the posts were not level. Eventually he said the door would need to be cut, which we agreed to. The door and posts were both cut to fit, but massive gap left at the bottom, and only half of the door fittings and no handles were installed! In addition, where the door was cut and the wood shaved made, a lot of mess was left all over the garden furniture and patio floor. Shocked at the lack of care and professionalism. He was clearly agitated and in a rush to leave. We have a working back door, but it looks like a real botched job. Not happy, and I would not recommend.

We had a full house renovation and loft conversion completed by Reform Build Constructions two years ago, and we’re still extremely happy with the results today. From the start, their team was professional, well-organised, and clear about costs and timelines. They guided us through every stage of the renovation, offering helpful suggestions while making sure our ideas and preferences were always respected. The quality of the workmanship has truly stood the test of time. Everything was finished to a high standard, and two years on, the loft conversion and renovated spaces still look fantastic and function perfectly. The loft has become one of the most used and loved areas of our home. Communication throughout the project was excellent. We were kept informed at every step, and the team was always approachable, punctual, and respectful of our home. They also made sure the site was kept tidy and safe, which made the process much less stressful. Completing such a major project on schedule with lasting quality shows their professionalism and experience. We would confidently recommend Reform Build Constructions to anyone planning a home renovation or loft conversion

Extensions- 2 Oct 2024
He did the extension well, brick work is good, rendering on front of house good, terrace and wall with the neighbours good ,toilet under the stairs good, dividing wall in the living room with sliding doors good, kitchen installed good. Fence wall in front of house good brick work wrong bricks but it’s ok. Herringbone parchet wrong with gaps and lifted, rendering on the side of house wrong with marks, the new boiler took 2 months to make it work and the radiators still don’t work. Electrical work bad, after bringing another engineer to check we discovered at the boiler live cut cables that were loose and veri dangerous. Took 4 months to finish job we waited one month for the plumber who either way did a bad job. Laurentiu did not finish the job because of plumbing and rendering, and we ended in bad terms, he left us money to compensate for it. I would recommend him for extensions and any brick work, he needs to improve in pluming, electrical, flooring and rendering.

Extensions- 7 Apr 2025
Quotes were provided and the job was agreed upon. The project involved a full house restructuring and extension build. However, after several stages of work, communication with Jas was lost, and his co-worker took the lead on site. Several issues arose, such as recommending smart plumbing equipment for purchase, but their plumbers were unable to install it. The tiling, skirtings, and tiles were not completed. Tiles around the columns were cracked. After Jas's team abandoned the project, another plumber had to install all the remaining items. The job was left unfinished, and we had to find alternative contractors to complete it. Significant time and money were wasted due to persistent communication problems, failure to issue invoices, and numerous other issues. Eventually, Jas and his main labourer stopped responding and disappeared, ignoring phone calls and WhatsApp messages. Be aware of these potential issues.

Extensions- 25 Aug 2018
Ricky completed a porch for me including the following work: Built an enclosed porch with sky light Refurbished the WC next to the front door Block paved the front garden Painted the hallway and doors I found him to be very approachable and flexible to changing requirements. He was competitive from the outset and honest on his cost estimates. As with all builders the time taken is longer than stated and you have to supervise the work closely to make sure you're happy with the progress but that aside I wouldn't hesitate to recommend him or use his services again. edit: Shoddy workmanship now showing through as block paving has all cracked as they didn't lay appropriate base. Costing a lot to get it fixed.
