Plastering- 28 Apr 2021
Jay came to price the job after making contact and his communication was clear. We live in a very old house with lots of quirks; he took this into account and saved us a bit of money with the plastering. Plaster was falling off the ceiling and a couple of walls and he inspected the whole room, telling us we were fine to leave two of the walls as they were, as all seemed solid. I imagine he could have told us to have the whole room done, but instead we only had done what was needed. Jay managed to slot us in quickly, completing the work over two half days (allowing the pre-plaster adhesive coat to dry over night), finishing the job on a Saturday morning as a team of two. The price quoted was what we were charged. It's now been about a month since the work was completed, and we're very happy with the results. The room was skimmed nicely and the surface was very smooth. We coated it with Screwfix bare plaster paint before giving it a top coat, and the finish is great. We'll be using him again for future jobs and I have no problems recommending him.

Plastering- 4 Nov 2024
LMG have just completed a full silicone render of the back of our house, over 3 floors. Really pleased with the work, and the general standard of updates and quality throughout. To find a company so reliable, with such great work is really hard, and wouldn’t hesitate to use them again. Chose SeaMist colour for the Johnson’s render, and it looks amazing. Also very pleased at the scaffolding provided, and then very swiftly removed.

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