Did a fabulous job on my back yard concrete patio which was crumbling in places and needed levelling. Also suggested adding another step to a rather steep step in place already which made perfect sense and he did a great job with that too. Took 1 day and sent photos of the site after work. Very impressed and very happy with the outcome. I recommend this company and will be using them again on other jobs in the future.

We have had our boiler replaced recently replaced by Nigel at Beaumont Plumbing. Excellent service and very professional. Would recommend to everyone. We have had issues with our heating and radiators since we moved in 6 months ago but no one was able to fix. Very reasonable price. Since fitting us with a new boiler Nigel has kindly organised our roof to be repaired. The guys were so lovely and professional. I now have a sealed roof and warm house thanks to them. Definitely will use them again.
