Extensions- 24 Apr 2019
Darren was on site every day without fail. His work was 1st class. He knows his job and is very experienced. He was able to give us a start and finish date and he kept to those dates. He cleared and cleaned the site every day. He was an absolute joy to be around and went the extra mile to ensure we were pleased with his work. I would not hesitate to recommend him. His brickwork is a pleasure to look at and both the extensions he built - a rear extension with bi-fold doors, and a side extension (the garage) both look as if they've always been there. Craftsmanship at its best. He knows the building regs required, his standards are 100% good. Darren's prices are extremely competitive, he's no rip-off merchant.

Extensions- 9 Jan 2019
Altun Property stepped into the project very anxiously and positive. The management were very helpful and assist us with the neighbours requirements, as our building is adjacent to a primary school. The project went thoroughly and took some time because it was a big project. Altun Property were very energetic and supportive throughout the work, they didn't object any amendment the project required and extra work needed. We have received several compliments from visitors to our office for the level of work conducted and the quality provided. Commissioning the work to Altun Property helped us heavily as a charity because we were able to save on the overall cost of the work. I would like to express our appreciation for the work conducted and look forward for further work together.
