10 Great team
Posted 11 March
Great from start to finish. From first meeting to discuss plans through to the final snagging, the team were extremely professional. Miguel and team cleared up every night before they left, worked long days to get everything done as quickly as possible and to a high standard. We had a big issue on day one when they discovered a huge crack in our original base but they very quickly worked out a plan and got everything back on track. Management team followed every step of the process and kept us up to date on what was happening. Brilliant team and we are very happy with the final result.Verified reviewerJob location: SE28- MMustafa I

Job location: EN3I used Cornerstone Design & Build / Braithgate Construction for previous works and the experience was excellent from start to finish. Communication was clear and honest throughout, timelines were respected, and the quality of workmanship was very high. They were reliable, well organised, and paid attention to detail at every stage. The site was kept tidy and any questions were dealt with promptly and professionally. I would happily use them again and confidently recommend them to others.- JJames B

If you’re looking for honest builders, quality workmanship, good value and impeccable customer service then look no further. Highly recommend Cornerstone, no job is too small for them and they do not cut corners. They also have a team of experts eg. Plumbers, Electricians and Builders to save you money. They do everything from kitchens, bathrooms to full house renovations. The most important thing to me was time and commitment. Cornerstone are extremely reliable, they turn up as scheduled and completed jobs as agreed. Furthermore, they provide excellent aftercare. Cannot recommend them enough.Verified reviewerJob location: HA110 Wall and Ceiling repairs, stairs renovation, doors fitting.
