Norbi is an exceptionally talented carpenter. He was the team lead on our major building project when we restored our Victorian house over an 18 month period. All his work was superior, from replacing ceilings and ceiling roses, to laying the new herringbone floor with electric underfloor heating. He was always polite, well mannered, and respectful. Norbi takes pride in his work and genuinely cares about the finished result in your home, a rare quality amongst many. We cannot recommend him highly enough.

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.

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

Fencing- 13 Mar 2026
We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

Akash made sure the job was complete exactly how he said it would be, he provided reliability during the installation of our kitchen and answered all questions very professionally. The builders were well aware of the conversations my mother and I had with Akash and so put our mind at ease. The installation itself was very quick (the tear down was very much completed in a few hours) and installed over the weekend. They were very hygiene aware and set up a cover between the kitchen and the rest of our house and didn’t disrupt our home living. They cleaned up before they were gone to very high standards without us even asking them too, all I’m sure is due to Akash’s excellent organisation skills.

Plastering- 6 May 2025
Amazing guys. Hardworking, tidy, professional. They worked in our house for 3 months and we were super happy with the work and everything. We invited them to do more work later on. 100% probably the most sincere and trustworthy builders we met. Only them. No one else from now on.
