Kitchen Fitting- 18 May 2017
Cannot fault the work Tony undertook. Completed on time, finished to a very high standard, kept informed (we were away on holiday whilst work was being done). So pleased with the result, my daughter's room is what was the kitchen and looks beautiful. New kitchen fitted with new floor tiles and looks fantastic, boiler was moved etc. Can't recommend Tony enough and I will definitely use Marsdens again.

Bricklaying- 30 Oct 2026
Great service received from GpmBrickwork Ltd. Received a prompt response from Gordon who then came around to quote. We found Gordon to be punctual, reliable and knowledgeable. Gordon and his Son Michael returned to do the job, which was to build a new front step. They arrived on time and worked efficiently and timely. My Husband and I are very impressed and delighted with our new step. Everything was left very tidy and we have no hesitation in recommending Gordon and Michael, and would happily use them again. Many thanks to you both.

Hard Flooring- 8 May 2019
I was very pleased with Igor’s work on the flooring and under floor heating, so decided to ask Raimundas to quote for a large bathroom, hallway, fitted kitchen, rewiring of all electrics and flooring throughout the rest of the flat. Due to work and my partner living overseas, I needed to trust somebody for a long length of time with my keys and my property. I was able to have a lot of the work done while not in the country, communicating with pictures, videos etc. Obviously this was important for me and made having the work done easier. There were also many problems with the kitchen delivery and other things that didn’t go according to plan. Raimundas was patient and polite at all times, even though it was sometimes rather frustrating. I highly recommend his services, and would definitely consider RR Construction for the next job
