Plastering- 4 Aug 2026
James was easy to speak to and took the time to answer all of my questions while we finalised the scope of work and contract. His quotation was fair and competitive. The work included replacing the felt on the side extension and dormer flat roofs, as well as applying a silicone render to our Mock Tudor house, all of which was completed to a very high standard. The roof tile repointing, valley leadwork, fascia and gutter repairs were carried out thoroughly, and the roof now looks neat and tidy. A few small items that had been missed from the original contract, but James was happy to take care of them without any issues. James was professional, courteous, and reliable throughout, providing a hassle-free experience from start to finish. His team did an excellent job, kept the site clean and tidy, and completed the work with great attention to detail. I would be more than happy to recommend Ridgewell Roofing & Building Ltd. to anyone looking for high-quality roofing & rendering work.

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.

Tiling- 9 Aug 2026
**Excellent service – highly recommended** We used Vasile and his co-worker for the reinstatement work following a water leak, including piling, plastering and painting, and we couldn’t be happier with the result. From start to finish, they were really nice, polite and professional. They worked quietly and respectfully, kept everything tidy, and clearly took pride in what they were doing. The attention to detail was particularly impressive, and the finished work was completed to a very high standard. It was a pleasure having them carry out the work, and we would happily recommend them to anyone looking for reliable, skilled and considerate contractors. Great job!

Extensions- 10 Jun 2020
We had a one bedroom lower ground floor garden flat and did a side return and extension into the garden. The flat is in West Kensington area. We also did a full internal refurbishment and moved just about every wall, moved boiler, new Porcellanosa bathroom, new kitchen, new flooring throughout, a large bi-fold door in the living room to the garden. Chris and RAS Construction have been the best possible builders for this project. They were simply amazing. What we loved most about them: - speedy and no-nonsense communication (very important for us) - friendly and approachable - super professional and friendly team - very quick and helpful when a problem arose due to some architect's error - good aftercare - stayed in quoted budget - offered improvements and reasonable quotes - very easy to work with - only asked for partial payment every few weeks after job had moved along reflecting the amount charged This review was written about 8 months after the project was completed and we are still very happy with the quality. I would not hesitate to recommend Chris and his team at anytime. You hear so much about bad builders, we have been very lucky that we have found him. We are now house hunting for a bigger place and will re-engage with them for the next project.

Electrical- 26 Jul 2026
Genuinely one of the worst builders we have come across. David rewired the flat and Stefan plastered the hallway. David is NOT qualified as an electrician and cut corners wherever he could. David leveraged us for money mid job and in the end left the job without finishing and without providing a certificate. David ran cables behind door frames (awful idea), got the cheapest material, forgot where holes were for spotlights and switches among many issues which meant we had to constantly ask our builders to fill the holes and make good. Stefan did the hallway plastering without putting on mesh. The plaster cracked within 2 weeks and the paint keeps cracking and will be a constant problem. When asked to come back and fix the issue - he point blank refused. They were the cheapest quote but we really hope we had gone to someone else

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.

Carpentry- 13 Aug 2026
Alex did what I asked and did a great job installing the awning. He also installed a metal shed and put up a beam to cover part of a wall. Overall, the work was good, although a few small details were missed in the shed, which seemed to be due to a lack of attention to detail. I found the price a little expensive, but overall I’m happy
