You couldn’t have made it any easier for me

Can you please pass on my gratitude to those who attended the property and carried out the work. I am very grateful for the work and service from your whole team and my experience working with AP Gooch, from my first conversation with Adam Vickers onwards has been a very enjoyable one. You couldn’t have made it any easier for me.


The standard of workmanship was second to none

Work was carried out by AP Gooch building company on our house after we moved back to the UK from overseas. We were extremely happy with the efficient service and level of professionalism shown by all the workmen involved and the standard of workmanship was second to none. We would not hesitate to recommend this company to anyone. AP Gooch are a company that you can trust.

Bent over backwards to help me

Anthony was the third contractor to visit site and provided us with not only a quotation but support / encouragement as this type of work was new to our company. I soon realised that the two previous contractors had actually given bad suggestions for solutions, as pointed out by Anthony. I used google and found Anthony was in fact correct.

Anthony is an absolute gentleman, bent over backwards to help me. I feel very lucky to have AP Gooch as one of my trusted contractors.

Example Project

The waterproofing created a habitable Grade 3 environment to BS 8102:2009. AP Gooch installed the System 500 waterproofing solution to manage and remove any ingressing water and 8mm Cavity Drain Membrane was installed to the walls and floors of this large basement. Read more.
