Rating: 5 out of 5
Extension Builder in West Wimbledon
I am an experienced and fully insured builder. On average I and my team build and renovate 5 extensions per year. Our current or old clients are always ready to share positive feedback about our work. We work off the ready plans which are usually prepared by the clients themselves and approved by the local authority. As of now (30/03/2023) my availability to start the new project is late April or early May. Please get in touch and I will be happy to assist.

Extensions- 4 Aug 2020
On a cold November evening, Tony and his team turned up to provide a quote and within a week this was received. The quoted price came in the middle of the pile, which was a good start and aligned closely to the ballpark figure I'd received from a friend who was also in the trade. We then visited a site they were finishing off, and Tony had the confidence to ask us to speak to the client without him there and they gave us the confidence to proceed. They started in January 2020 and rapidly moved through the works and engaged closely with my architect, Structural engineer and building control and proceeded based on their recommendations strictly. We lived in the property as build progressed and the team ensured that the site was secure every evening and we were safe. As COVID-19 hit and we went into Lockdown, the team continued to come and work (we were separated from them as the house was boarded up) and the only challenge was getting supplies. Tony scoured all over London, picking up items as best as he could and work continued. Once they'd broken through into the old part of the house they continued to progress rapidly and showed utter professionalism. The team lead's attention to detail is impressive, and he gave great recommendations on what would be the right approach when we were laying out features such as window sizing and lighting. The standard of work is excellent and I would highly recommend them.

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.

Kitchen Fitting- 9 Jul 2026
I hired Blend for a light house renovation. It started off really well then towards the end he ghosted me. No reason given. He didn’t answer phone calls or texts. There was no fight or disagreement. There is no decent reason why he shouldn’t communicate with a client. You can simply just say you have another job or you are not interested any longer. You don’t ask a client to buy stuff knowing you are not going to show up. It is an unacceptable and unprofessional behaviour. Because of this it’s cost me time that I can’t get back. But I guess it is what it is. I had to find another builder to complete the job. Some of which was not done properly. For example: my kitchen sink was leaking both inside and out. Had to buy a new toilet as something was broken while he was refitting it and etc. Pros: Blend is a nice and easy person to deal with. He is generally a nice guy. Tiling ✅ Cons: Finishing is not so great. could be a lot better. I also found patches and over paint on doors and others.
