Really happy. Good quote, sound advice, excellent communication. All in all an extremely professional service from honest, considerate and reliable tradesmen. John was fantastic when we had to delay the work for a few months and even kept to his original quote. The work done was to a very high standard and I couldn't be happier. Will definitely use again and have already recommended to friends.

We hired Gowan PM to decorate our first project of 7 apartments. They are so much more than your average tradesmen; multi skilled, (great tiling and bathroom installation) tidy (put our team to shame), when we changed a main colour they were fab and just took it in their stride. We forget to order materials so they collected it for us. The quality of the work is second to none and has been admired by all. I have no doubt that it will be their work will sell our project. A huge thank you, now our 1st choice.

We only had a small job and wondered if anyone would want it. Martin contacted me, was very helpful with product selection - he made the purchases and did the job within the time scale he predicted. Very courteous and pleasant and took any rubbish away with him - very impressed - we will definitely use him again - thanks Martin

Davall Construction left my home unsafe,with the exterior wall collapsing and a big hole in my wall,just because I complained about their standard of work.I raised concerns about the shoddy brick laying (Laying brick and mortar to plasterboard),not replacing wall/floor vent (causes damp/rot),cutting/damage new door frame to fit (Instead of cutting wall bricks),not using wall or ceiling supports (acrow props),packing lintel with wood not slate and they just removed everything and left a huge hole in the wall

We are a small business that provide plumbing, building, tiling and property maintenance services. Bespoke projects undertaken and a specialist in bathroom /wetroom installation. Central heating installation/maintenance. Fully Gas safe registered.
