Bathroom Fitting- 14 Nov 2019
We had our bathroom completely refurbished and Graham the owner was lovely. He came to give us the quote, visited whilst work was being undertaken to make sure everything was okay and came to make sure everything was finished to how we wanted it. The work carried out was of a high standard and whilst the bathroom work was being completed we also ended up getting our kitchen worktops done by Graham’s team. Chris was the one who carried out our work, he was very friendly and checked we were happy with the work he’d done before he left everyday. I would use Graham again for other work needed around the house.

Latest review:
The project lasted from July 2023 to Feb 2024 and comprised of: 1. Single story rear extension with new kitchen and underfloor heating 2. 75m2 patio 3. Internal reconfiguration including removal / installation of walls, new flooring, plumbing (including new boiler), new door frames, doors and skirting, redecoration, carpentry for cupboards 4. Ventilation of existing roof The team are both friendly and professional with Alin always on hand to manage any questions / situations as they arise. The work is clearly costed and every two weeks a valuation takes place to ensure transparency of work undertaken both in original scope and any extras. The quality of the build was excellent, something the building inspector commented on. Alin was recommended to me based on past work, and I in turn would highly recommend him.

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.

What qualifications and experience do you have as an extension builder in Clerkenwell?

An extension builder in Clerkenwell should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Clerkenwell extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Clerkenwell?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Clerkenwell extension builder’s ability to deliver a result that meets your expectations.

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Clerkenwell extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
