Conversions - General- 22 Nov 2019
My experience with asset construction has been excellent. It was more of a trust thing and Andy was very professional and knew what he was doing. Andy was very honest and competitive as compared to other quotes I have got. I did not have to worry about watching over the builder or being over priced. I can say I can trust on any quotes he gives unlike some other dodgy builders. I had a major job completed by asset construction and will book them for any future work. All his workmen know what they are doing including plasters, plumbers and they do job to perfection. Unlike other builders who rush through jobs to get paid asset construction was more committed in completing the job to perfection even if meant taking longer. Thank you Andy for the great work

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!

What experience do you have with similar extensions in Chesham?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Chesham extension builder’s ability to deliver a result that meets your expectations.
