Valentin was fantastic. He was efficient and professional. He did a fantastic job and even cleaned up after the job. He was polite, friendly and knew exactly what he was doing. I will definitely be getting more work done by him and have even sent him to my parents house today after finishing my job, to get quotes for other work. Thank you for helping me out today. Much appreciated

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.

Bathroom Fitting- 6 Jun 2020
The bathroom was refurbished from top to bottom even changing the location of basin, toilet and shower. One worker employed by AGStar Ltd did the entire job including floor and wall tiling. The worker cleaned up the stairs and the hall everyday before finishing for the day. When requested to carry out additional small jobs, not part of the contract, the worker always obliged. The refurbishment of the bathroom was carried out to a very high standard by just one worker and in short period of 10 days. I would recommend this company for all building work although a little pricey!

Fencing- 21 Jul 2026
Lucian arrived on time. He explained what he would do and what materials and got on with the job. A lot of shrubs to cut and clear and he tidied and swept up as he went along rather than all at the end. Fence was erected neat and secure. Job well done.

Bathroom Fitting- 7 Sep 2026
Majid and his team did a fine job of turning 2 old horrid bathrooms into a dream bathroom/laundry! Everything went smoothly, finished to a high standard, and Majid was always on hand or a phone call away to answer any questions we had. It did take longer than anticipated, which was due to us changing our minds on a few things but also abit of time management and staffing issues. All in all a positive experience, Majid was a pleasure to deal with and I would highly recommend. Thanks! (Sorry for not reviewing you sooner!).

Roofing (Pitched)- 10 Sep 2026
James was very prompt and gave a competitive quote and was professional in his response. Gave quotations for repointing a valley gutter and for replacing it if there was damage. James arrived promptly with his assistant and did a very good job with repointing the valley gutter as the valley itself was fine. He also replaced 4 damaged roof tiles at no extra cost. Would be happy to use Ridgewell Roofing for future roof work.
