Highlights
“Mariusz helped us rectify a damp wall. We had damp plaster that had been affected by damp ingress and age. Mariusz was professional and very kind. The quality of his work was great and we couldnt be happier.”
“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 used Interior PSD for various carpentry and decorating jobs on my property in Kensington, London. I'm delighted with the job carried out by Mariusz and his team! He works efficiently and to the highest standards and is very helpful and flexible regarding the extra tasks that I asked for. I was pleased with the finished job and will definitely recommend Mariusz to all my family and friends!”

InteriorPsd LTD , fantastic from the initial consultation through to the very end. They were professional, honest, and respectful throughout, and did a very good job. They were highly skilled and knowledgable, able to advise on everything, and were really receptive to feedback and questions I had. Thanks Bright House Painting.
I cannot recommend Mariuz highly enough. I have now been using him for a number of years. You can forget any notions of what you think a builder is. Mariusz has an excellent manner and a positive disposition. He is thorough and he is someone you can completely trust. There aren't any hidden costs. He will give you a fair price and you can have complete peace of mind. He has repaired my flat roof, done my decking, plastering, painting inside and out. i have total confidence in his work which is why i will always choose him w hen available.
Mariusz understood our requirements and provided the most suitable solution to the task at hand. Great attention for details and really hardworking. Strongly recommended
I used their service on my project for out built office in my garden including gardening work. I'm happy with the quality of work. I'll recommend to friends and will ask other jobs in the future.

Mariusz completed two related jobs for us - raising the height of an external door and installing a lintel, and making good of the new opening. We were pleased with the work and Mariusz's communication. We have other work that needs doing and will ask Mariusz to do this for us.

Had the entire interior of our house painted, the guys did an amazing job. Everything is clean and very professional looking, they matched the existing colours perfectly. They were very accommodating and communicated well, I can definitely recommend them!
Mariusz and team carried out an extensive renovation of our flat during early 2022. The work involved complex flooring installation, replacing carpet with wooden floors throughout including adding insulation under the floor boards. A new kitchen was installed including a new boiler, and various other carpentry work as well as plastering was done. The work was done to a good standard and Mariusz and team worked intensively over many months. In addition, Mariusz was punctual and considerate with us living in the flat whilst the refurbishment was carried out. Thank you, would recommend

Absolutely brilliant service from Mariusz for a number of rooms to be cleaned up, painted and decorated. Mariusz always started on time and worked through to 5 or 6 o'clock every day without fail, with a strict 30 min lunch slot. Prices agreed at start were stuck to without any variation. Cannot recommend highly enough 10/10.
We were unsure of how to proceed with our interior design project but Mariusz was able to guide us with the right information. Professionalism on its peak. I am excited to work with this professional interior design company again.

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.
Check the TrustMark registerNever pay a large deposit up front. Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job.
