Extensions- 2 Feb 2018
I would highly recommend Graham for any building work required. Graham was originally asked to renovate an old extension which was built circa 1970, which had damp problems and was on a different level to the rest of the house. This, at my request, expanded to virtually a complete rebuild of the extension and a conversion of the garage to a downstairs toilet and utility room. The roof over the extension and garage also needed to be lifted to bring the extension and the garage to the same level as the rest of the property. Graham was extremely patient and always took on board any comments/suggestions I had during the building work and adapted accordingly. Graham also came up with ways to improve the overall look of the house and built an overhang porch area with rendering across the front and side of the house. The quote was very reasonable and was updated and the revised price sent to me as the building work progressed (due to my changes to the original work request). Graham organised building control inspections and kept me informed throughout the build. Graham and his team were extremely pleasant and professional throughout. Thank you Graham

Extensions- 18 Jul 2025
I recently had my conservatory remodeled by Pro-Fit UPVC, and I couldn’t be happier with the service. Lee and Chris were fantastic throughout the entire process—communication was clear and consistent, and they were incredibly accommodating, even with last-minute design changes, which they promptly incorporated into the quote. The quality of the workmanship was outstanding. Lee took great care to ensure every small snag was resolved before the project was signed off, which gave me complete confidence in the final result. Pro-Fit UPVC is a genuine, family-run company, and it’s refreshing to deal with such honest, reliable professionals—something that can be hard to come by in the trade industry. I’ll definitely be using them again and wouldn’t hesitate to recommend this exceptional company to others.

'Grand Entrance Installations' is an extremely well-organised and efficient company. Every aspect of the job of replacing my conservatory roof was meticulously planned and directed by Darral Taylor and I was kept well-informed at each stage of the job. Members of the company carried out the job in a professional and expert manner. Timekeeping was excellent and on schedule. I have been provided with a very high quality equinox roof at a very competitive price.

Extensions- 23 Sep 2023
I hired Jake, Brian and the team to carry out a single story kitchen extention. I had never undertaken such a large job and was somewhat overwhelmed and did not know what to expect. However, I was reassured by Jake and Brian on what to expect and what the works world entail. They took the project on and were in constant communications throughout the build. They organised building control inspections, kitchen fitters, electrical, plumbing, plastering, brick layers, the lot. I just had to sit back and see my dream kitchen come into fruition and boy it did! No job was too small, they made adjustments along the way and kept me informed of any issues and made me aware of anything that required extra work, we agreed to a price and they delivered. I am very happy with the outcome and any issues that came up later were dealt with promptly. I had some frustrations along the way(this wasn't jake's fault) but Jake took on the responsibility and rectified issues that were not his own. Its difficult to find a trustable and reliable builder these days but if you are reading this, please give Jake a shot, you will not be disappointed. I now have the kitchen I envisaged at a reasonable price and I couldn't be more happier. If you want a builder who is trusted, has an eye for detail and is always transparent... do yourself a favour and get in touch with J S Build & Renovate. Jake is a genuine hardworking lad that deserves the recognition!
