Groundwork & Foundations- 22 Mar 2025
I hired Paul to level and grade my garden after he provided the lowest quote for the job. Partway through the work, he requested additional payment to “dress” the garden for a better finish. I agreed to this, bringing his total price in line with the highest quote I had received from other contractors. Despite paying this additional sum, the garden was left in an entirely unsatisfactory condition and does not meet the terms of our agreement. The standard of work is far below what would be expected from a competent tradesperson, particularly given the extra payment made for an improved finish. I also want to highlight that I can find no company registered as “Paul Haley Design & Build.” Instead, Paul requested that payments be made to “GAIRNEY BUILDERS LTD,” This lack of transparency is concerning and something others should be aware of.
