Decking- 29 May 2020
Started on time and completed the decking extension & renovation to a high standard. Ensured that small details like cuts around poles etc, were finished properly and not left with gaps. Next time I would confirm that clearing rubbish is part of the quote, but highly recommend Przemek for quality finish.

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.

Extensions- 19 Aug 2026
We paid for the build finished in Sept. 2025. Our concern is the foundations. The drawings specified about 1.8m depth and anti-heave boards due to clay and trees. The builder had not properly checked the drawings, then charged substantial extra for the depth. We paid, but the boards were not installed, and our photos and videos appear to show much of the foundation at about 1m. A replacement Building Controller declined to proceed without evidence of the boards. The patio, including £1,700 extension, was laid without proper excavation or a mechanically compacted base. Some tiles are loose and render is failing. Other faults include uneven floors and walls, falling plaster, catching doors, cladding gaps, poor electrical fitting, missing vents, a possible leak and unfinished items. Attendance was intermittent—about three weeks over two months—and the work felt rushed around other jobs. Our neighbour witnessed two workers urinating behind the shed. We cannot recommend this company...
