Gelu is hard working and dependent guy, will not fuss about the job like many do, but will crack on with it. Stayed late to finish it at many times. I am quite happy with the finish and work. shower fit, washbasin, toilet, tiling all done to my satisfaction. After seeing the work I asked him to do more like kitchen cabinets and skirtings.

Extensions- 25 Apr 2022
We hired Brothers Construction to knock through our existing dining room and garage to create a larger space. From the start Dan and Jay have been excellent. As others have said they are a completely professional company who arrive on time, do a full days work and leave everywhere tidy. Communication, sometimes on a daily basis, is excellent. Halfway through the project we wanted to make a relatively big change to the job which didn’t phase them at all and this, together with any additional costs, were always "run by us” before proceeding. To say we are delighted with the finished job is an understatement and we can’t recommend them highly enough. Thank you Brothers Construction for looking at our scrappy plans and turning them into reality. Desperate now to start decorating!

Carpentry- 6 Jun 2024
Brian did an excellent job rehanging a door on the other side of the door opening. He explained the problems involved and how he would tackle the job. He achieved a first class finish and his attention to detail was second to none. He left everything clean and tidy. I would not hesitate to recommend him and I will certainly be using him again for jobs which need doing.

James managed our kitchen extension project and took ownership of all carpentry, and we couldn’t have been happier with the outcome. The project was delivered smoothly and to a high standard, and James was a pleasure to have working at our home. We especially loved the outdoor pergola / cinema area and hot tub decking he built too, which was technically quite challenging and looks absolutely fantastic. I would absolutely recommend Linear Carpentry to friends - and have done!

Excellent excellent builder. I can not recommend MAS Development Solutions highly enough. Initially I hired him to finish off some plastering work that another builder let me down on. In the end because of the flawless job he did, his fantastic attitude and great rates I invited him to do the refurb work on the whole house which included, plastering, tiling, bathroom fit, kitchen fit, wooden flooring, prepping a fireplace, rendering, removing a wall and fitting a new window. I'm happy to provide photos and more details for anyone that is interested. Matt went above and beyond what was asked of him, arriving early, working late, making helpful suggestions and picking items up for me. I'm so pleased to have a builder I can trust that does excellent work, with the right attitude at the right price.

What experience do you have with similar extensions in Dunmow?

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