New Builds- 7 Jun 2022
Sohail worked closely with me on this project. Providing detailed costings, work schedules and build timelines. Filling my knowledge gaps with his extensive experience he was able to assist over and beyond what I expected from him. Unfortunately due to circumstances out of my control this development project didn’t go ahead. However when the next opportunity for a new build comes up I will definitely be using Rose and Stone. I did have another job going at the time where the other builder badly let me down and left me with a big problem on my hands…. Sohail and his team stepped in and took on the project. The team finished the job exceptionally well, which was a full on top to bottom conversion, some internal reconfigurations and with the addition of a loft and new downstairs WC. The workmanship and overall quality of the job was excellent. My wife is over the moon with the results, taking the house from a three bed one bathroom to a four bed 3 bathroom house. We would definitely recommend Rose and Stone for this type of extensive refurbishment/loft conversion work and look forward to working with them in the future on bigger development projects.

I was very pleased with this company so much so that they are starting a new job for me November 15. The building firms carried out a full loft conversion for me installing bathroom, brickwork, joinery, plastering, Roofing and installation of windows and double glazed doors. I have high standards and want everything to be completed in the same way, the workmen respected my home and always left if clean. My main contact was with the owner of the company Dwight Lynch, he was very flexible and Nothing was too much for him to do. He has an attitude which I like in a builder "customer not always right but must be happy" he provided me with ideas along the way and where things did not go to plan due to my own instructions he worked around the issue and provided suitable alternative options. I was very happy with the pricing of the job and feel that certainly I would recommend him and also I would use him again. He and his workmen were all trust worthy and I gave them keys to my house to carry-out work whilst I went on holiday. I had no concerns when I came back everything was as I left it.

Extensions- 25 Aug 2020
I did my due diligence on Vullcan, but things went downhill. After a week i got a pre-tax invoice for £3000 for a more "complex" drainage system which was already completed, this was the start of them trying to get around contract items and look for every way possible to charge extra fees which i can’t go through in the word limit here. When that dint work they refused to do the work. e.g. they literally installed a tempered glass sheet, with liquid glue on my roof and stated to me that this was a "roof window". I had to show them buildings regulations that this was unacceptable and illegal especially when our contract said it has to be a VELUX ROOF WINDOW! Promised a 6-8 week completion, this is 9 months later. I had now paid about 90% of the original bill and 100% of additional costs. The final payment was due after completion and a 2 week snagging period. But the demand for payments started, with threats to sue. This was laughable as they hadn't completed the job. •The roof was leaking •Electrical issues with the fuse box and multiple light /electrical points •Outstanding items •The buildings controls company stated they would not be able to sign off on the building work because of outstanding issues, which I wouldn’t have even known as they lied stating they HAD the certificate. I agreed to send a FULL payment to an escrow company and pay HALF of the costs so they can complete and fix safety issues but they refused! Shameful experience.
