Bathroom Fitting- 19 Jul 2024
Shoreline Interiors completed our kitchen and bathroom today. They have been thorough and professional throughout the job, working long hours to get the job done. My wife and I found Ken, Matt and Tom to be extremely thorough. They talked through the job with us before, and at all stages during the work. They were quick to solve problems, and offer suggestions. Nothing, I have to say, seemed to be too much trouble. But what sets the guys apart, in our opinion, was their attention to detail. They had a snagging list before we did, and no detail was overlooked. They made sure that they left us as tidily and as organised as possible. The finished bathroom, and the make over in the kitchen look amazing. The quality of the products and the work is perfect. I highly recommend checking Shoreline Interiors out.

Plastering- 1 Jun 2026
I hired Joel to render and plaster some indoor walls for my Terrace house renovation. He was professional in his visits, and his work was excellent. He also left the workplace as clean as he found it. It was a pleasure to work with Joel, and I shall certainly be using him again. I have no hesitation in providing a good review for him. Gareth.

Extensions- 12 Mar 2019
We are very pleased with the quality of work on our extension which has been completed within our budget and on time. Jon and P.J are friendly, trustworthy and approachable and kept us informed throughout the entire process. We had a few issues with the lack of detail of our plans and some unexpected challenges; but Jon and P.J always explained fully what possible options we had to overcome them rather than just carrying on without consulting us. The site was left in a clean and tidy state on completion. We wouldn't hesitate in recommending JM Construction to others looking for quality construction at a competitive price. Thank you!!
