Latest review:
We hired Iain to complete a rear single storey extension, to create an open plan kitchen and living space. Iain and his team were very efficient and open throughout the whole build. The work was completed in less than 3 months. Iain was very approachable and informative about the process and decisions to be made, and offered expert opinions throughout the project. We have young children and Iain and his team were very accommodating to our family life and ensuring the area was safe! We are really happy with the build overall and the quality of work produced. I would highly recommend IML Building and I would definately use for future projects.

Bricklaying- 14 Sep 2026
EEGL came out quickly to re-lay a collapsed front boundary wall. Fair quote, turned up when they said they would, and the finished wall is neat and solid clean pointing and properly matched to the existing brickwork. Very good brick layer. All neighbours said wall looked amazing. Tidied up afterwards and were easy to deal with throughout. Would happily use again. Using again for another wall.
