Bathroom Fitting- 27 May 2026
Had a great experience with this team. On time, worked hard, communication was spot on, attention to detail was thorough and overall good value for money. Really pleased with the finished job. The quote was clear and all changes were discussed and agreed as we went through. Would definitely use again and recommend. I could see that they really care about getting it right. That makes all the difference.

Extensions- 29 Jan 2015
PM Building epitomise what a modern day, professional building firm should aspire to be. Transparent pricing, a friendly team working 6, sometimes 7 days a week to get the job done quickly, an eye for detail and very high standard of final finish. All comms and the overall work is run through Bart, who answers to phone, text or email quickly and frequently outside normal working hours. This is ideal if you work during the day and cannot be around to oversee things directly. We also got PM Building to make us a bespoke kitchen, again very high quality and millimetre perfect. If I had to find some negatives, they are not the cheapest company you could find, but there again you get what you pay for; also, we developed a few issues with some retaining walls in the garden, however, they returned when I contacted them long after the work had finished and fixed them! All in all, an excellent, honest and professional company to deal with. I would, and have, recommended them to friends...nuff said.

Painting & Decorating- 27 Apr 2018
Claudiu and his team did an excellent job renovating our 2 bed flat in Bushey. He did a great job on the laminate flooring in particular. Installed coving, skirting, painted walls/doors/radiators, installed new light fixtures, and assembled furniture. Will definitely work with him again. In fact, I hired him back to do our bathroom next week!

Plastering- 5 Aug 2019
The job was more than a standard plaster job it was a complete refurbishment of the dining room with the new flooring extending into the hallway. Ionut did an amazing job his attention to detail is first rate I have used quite a few builders over the years and I can honestly say Ionut impressed me the most. He is hardworking, meticulous to detail, tidy and goes above and beyond the job that has been agreed. An example of this was him deciding to hide all loose wiring while he was doing the skirting which has made things much more tidy and also doing new flooring and skirting under the stairs without me asking. He wrapped everything in plastic during the job (radiators, doors, light sockets etc) no plasterer I have used before took that much care in protecting things during plastering which as we know is a very messy job. We will be recommending to all our friends and in the future he will be the first contact if we need any more building work. 100 percent recommend his services and thank you Ionut for the job you have done for us

Kitchen Fitting- 7 Sep 2026
Isac did an excellent job removing my old dishwasher that was stuck in place and fitting the new one at very short notice as the firm booked in to do the job couldn’t remove it. He even helped with getting a loose hinge secured and adjusting the base board to go back into place. Highly recommended
