    "Full main bathroom renovation including installation of underfloor heating and rebuild of an internal wall. I was very pleased with the finished product it was fantastic, and very grateful for all the help Interior Psd LTD gave me in the design phase. The team work very hard and they care about doing a good job. The project took longer than expected but it was worth the wait in my opinion. If you care about quality I recommend this company."

    "I have had work carried out by Mariusz a few times over the years. He did an overhaul of my flat which included laying wooden flooring throughout, painting and decorating and carrying out repairs. He is trustworthy, polite and very friendly. He is also very knowledgeable especially when you it comes to resolving any issue you need input on. The work he does is of a very high standard. His prices are very good and fair. I needed work done on my flat recently and he was the first person I called as I knew he could be trusted to carry out the work I needed in the timeframe I had. He did not disappoint. He removed wooden flooring in my kitchen and replaced it with slate tiles. This was done quickly to his usual high standard. He also repainted the flat and installed a bathroom cabinet on the wall. Another thing to highlight is his tidiness and care of your property. He ensures any waste is removed quickly and surfaces are left clean. All in all I cannot recommend him highly enough."
