Kitchen Fitting- 27 Nov 2024
We decided to fit a new kitchen in our tenanted house all done remotely via Australia. We are very pleased with the final kitchen and credit to Oliver for staying committed to the job. He communicated well throughout the process and as a result there were no surprises. This was not an easy process as we were dealing with a difficult tenant that we were trying to remove at the time. As a result the new kitchen was fitted but Oliver had to come back months later to finish the job. I know this was frustrating for him but with mutual respect and trust we got the job finished and I thank him for his patience and honesty. Would recommend his services.

Haxhi and his team exceed my expectations. We did agree on a bathroom renovation which basically everything was done from scratch. He was always on time and he met the deadline of the project. I had an issue with my water pump but he managed to fix it for little cost. Also he did the tiles for me on the wall and floor with very minimum waste and he did a brilliant job. We changed the position of the basin in order to save space and we did replace it the washing machine(hidden). We are now working on my other property to renovate the bathroom. Hahxi is very professional, knows the job very well, he did coordinate with me on every step to make sure we are on the same page . I strongly recommend him for any renovation project you may have.

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.

Bricklaying- 29 May 2026
Giani and his colleague repaired our wall beautifully for a reasonable price. He talked us through the issues that caused the wall to fail and explained what needed doing. He started the job the next morning arriving promptly and then went about the job with care and pride. I can whole heartedly recommend AGB Construction to anyone looking for builders with good communication, a sincere pride in their work and honest fair pricing.

Bathroom Fitting- 13 Oct 2015
Reece and his father did a great job in our bathroom and he was a real pleasure to deal with . He went above and beyond the role as he had to order and collect a bath end panel as he suggested it would be a better match from the one I had selected . He was correct in this. He is he first builder I have ever known to suggest an improvement, source it and collect it as part of the job !! I would thoroughly recommend him. :)
