TESTIMONIALS
Ollie Young.
"Andrew and his team we always very punctual, polite and very respectful throughout the weeks of work. They completed the removal of the chimney and stack through the centre of our property across 3 floors.
Work was finished on time and left the house in a clean state which wasn't easy given the level of dust."
Martin Burke.
"We were really pleased with the builder, his team and the tradesmen he uses to do all the specialist work. We would have no hesitation in recommending APH Construction.
We have a beautiful kitchen/diner extension that is brilliant social space for us as a family."
Joy Green.
"We had a loft conversion and a single level extension to the back of the house. We found Andy to be very thorough and paid attention to detail. We had issue with a couple of the contractors but Andy got this sorted and we have got an excellent result.
I loved the way Andy had ideas and worked through the problems to get a house that was better than I expected. They managed to accommodate my quirky ideas! They are a great team to have around the place!
