Roofing (Pitched)- 2 Sep 2024
Chris and his team at Bravo roofing just carried out a full re roof on our house. Chris's quote was detailed and the price was competitive. Communication was great with Chris all the way through, they turned up when they said they would, were courteous while working here and left the place tidy. We are extremely pleased with the work carried out to. We would have no hesitation in recommending Bravo roofing to any friends or family.

Plastering- 19 May 2026
Mike has just plastered my bedrooms, bathroom and hall and stairs ceilings. I have no hesitation in recommending him to other people. It was refreshing to have somebody who is conscientious and arrives on time. He always replies when you leave him a message and the quality of his work is excellent. I found his costs to be very competitive and nothing is too much trouble. I have already recommended him to my daughter and one of my friends and will contact him again when I need more work doing.

What experience do you have with similar extensions in St Helens?

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