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.

I would like to say that this work was completed perfectly. They were always on time and cleaned up after themselves. The plumber was there all day and never stopped. We found them all very approachable and helpful. No pressure sales. Would gladly have them back for another job and would recommend them to others.

Extensions- 25 Aug 2018
Ricky completed a porch for me including the following work: Built an enclosed porch with sky light Refurbished the WC next to the front door Block paved the front garden Painted the hallway and doors I found him to be very approachable and flexible to changing requirements. He was competitive from the outset and honest on his cost estimates. As with all builders the time taken is longer than stated and you have to supervise the work closely to make sure you're happy with the progress but that aside I wouldn't hesitate to recommend him or use his services again. edit: Shoddy workmanship now showing through as block paving has all cracked as they didn't lay appropriate base. Costing a lot to get it fixed.

Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.
