Bathroom Fitting- 17 Feb 2025
From start to finish the team was superb. Josh was helpful in suggesting ideas to make the most of the job. Bradley, Ray and Dave were all expert in their work and the job progressed quickly. Josh was excellent in communicating with us to advise who would be arriving the next day. As older clients we appreciated workers with whom we felt comfortable. The whole process gave us an ensuite to be proud of. Expert workmanship and a very pleasing finish. Would not hesitate to employ this contractor again.

Extensions- 1 Sep 2021
I have nothing but praise for Michael and his team. The project was managed exceptionally well and Michael kept us apprised of progress, emerging issues (which were dealt with quickly and with some innovative thinking) and he was honest and candid with our choice of kitchen tile (I think his words were do you want to rethink that colour!). Michael quoted in Nov and started work in the Spring (late Mar) and held his price despite a national increase in the price of materials and reduced availability which he managed admirably. Obviously a man with a good eye; his suggestions for additional works were inspired and they have resulted in a high quality finish. Finally, it is worth mentioning the team who did the grafting! Very industrious, skilled, polite and helpful. Highly recommend Wooburn PM to anyone considering building work. :-)

Chris hung a number of prefabricated doors and door frames that needed adjusting. He promptly provided us with a detailed quote and his availability. He did a job on a Saturday which was great as we really need this job to be done as soon as possible. The job was completed quickly, the adjustment to the doors are practically not noticeable and the doors and frames look great. Chris and his helper were very helpful and did a great job for us. Will definitely us Chris's services again.

What to ask a Blackfriars extension builder before hiring?

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

An extension builder in Blackfriars 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?

What experience do you have with similar extensions in Blackfriars?

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 Blackfriars extension builder’s ability to deliver a result that meets your expectations.
