The job went exactly as he promised. Delivered on time, for the price he quoted. Oliver was professional from the outset and super helpful, as I annoyingly asked lots of questions. His workmanship was second to none, wholeheartedly recommended. Will be using again.

Extensions- 1 Feb 2023
We are in the last week or so of the extensive remodelling of the kitchen, utility room beyond plus bedroom upstairs. Mark Lomas and his team have been truly amazing, not just in exercising real building skills to blend the extension harmoniously with the existing Edwardian home but also in some imaginative problem solving as well. Costs have been spot on budget, save where I have caused additional work and fitting out, other than some unusual costs arising from some specialist joinery work which enabled the timber windows and doors to be exact replicas for others built 120 years ago. Honestly, I could not speak higher of the care and attention we have been given. I could get cross about the driving rain and the gruesome frosts and miserable cold, but that's a British Winter for you; Mark and his team certainly did not grizzle, and have stayed professional throughout. Circa £100k budget, so a reasonably size job and quite a risk for the builder - for my next project, I shall certainly use again in a heartbeat.

Costal has done a great job. I wouldn't say he was the cheapest quote but after reading the reviews we hired him because of his reliability. I found him reliable and always turned up when we needed during the project. He recommended us other contractors and supported us to achieve the goal we were trying to achieve. I would recommend Costel 100% if you want to have reliable builders for your home. Thank you

Extensions- 28 Nov 2017
Well what an absolute pleasure! Quite simply one of the most professional tradespeople I have had the pleasure to hire. Vasile and his entire crew were all polite, professional and extremely hard working. They were onsite almost every day without fail no matter the weather, worked quickly and often long hours. Everything that we asked for was done to a premium finish, and often Vasile would suggest alternatives that would work better. They were also able to make alterations once the job was started as circumstances in the build changed from outside factors. The quality of the finish is top rate, and the end result is absolutely stunning, the work has totally transformed the house. I cannot recommend Vasile and his team highly enough, and will happily recommend them to all my friends, family, neighbors and co-workers. If we ever extend or have further need for a builder he will certainly be my first choice. To sum up, Vasile is competitively priced, trustworthy, a hard worker and highly skilled. I wish to publicly thank him for his dedication and keeping the whole experience as painless as possible!
