Extension Builder in Croxley Green
I'm a builder with 28 years experience. I specialise in extensions and loft conversions. I'm honest and hard working. I take pride in my work and ensure its of a high standard. I'm multi skilled so I'm able to build most aspects of a project myself. That way I can guarantee the quality of the work. Most of my work comes from word of mouth. I get lots of recommendations from previous customers. I'm hoping to increase my workload by advertising here. I've got a large portfolio of work and previous customers that will give good references.

Kitchen Fitting- 8 Mar 2025
Spoke with Contempo and they stated they would be able to attend to do the job that evening as they would be in the area, they arrived at the time stated and carried out the works there and then as required and expected. Provided a demonstration of the fan working and also installed the cupboard door to the face of the extractor unit. Cleared up and charged the amount that was agreed. Great, reliable and professional service.

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. :-)
