Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

Extensions- 5 Sep 2019
The builders did an incredible job refurbishing my house. For my house I wanted to break the internal wall to create a bigger living room and also for them to refurbish the toilet. In the beginning they’ve set a period when everything will be done and they’ve stuck to it so they are trustworthy. Seeing the progress, I could definitely tell that they were working incredibly hard and I know that they have been working long hours to ensure that they manage to finish it within the timeframe that they’ve set. I would definitely recommend them.

Kitchen Fitting- 29 May 2024
Nesha was brilliant from start to finish. He was excellent at communicating before the job and was entirely professional and hard working throughout, not to mention his quote was very reasonable. He worked really hard to get the job done quickly and he did it to a fantastic standard. We are so pleased with the finished product and he was a pleasure to work with. We cannot recommend Nesha highly enough.

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.

Bricklaying- 19 Apr 2016
We have always found it a problem trying to match the correct tradesman to any work we have needed doing, so much so that many jobs have been left undone. You either end up with a personality clash, or just plain bad workmanship, well not this time. The entire process was a joy from start to finish, from the initial quoting process, to the completion and the standard of work was exemplary. Nothing seemed to be a problem for them and they were very pleasant to have around. We are busy drawing up a fresh list of jobs we need doing and would certainly thoroughly recommend them. If you have had any bad experiences in the past, give them a try, you will be very satisfied.

Demolition- 24 Nov 2021
We employed A.V Structures for the building of an external wall around our property, the removal of a garage and the installation of railings and gates. Throughout the 4 week programme we could not have been happier with their work. Arrival was prompt, their pace of work displayed energy and purpose. They were mindful of us and our neighbours and made sure the area was left clean and tidy at the end of each days work.in addition the workmen were courteous and kept us fully informed. Alex, the owner of the company, kept in close contact with us to assure himself of our satisfaction. He came on site at intervals to check that all was going according to plan. We therefore felt completely confident that quality and outcomes were important to him. Employing A.V Structures was a decision we were pleased to have made. We would use them again without hesitation and recommend them highly to anyone considering similar work.
