Carpentry- 31 May 2017
Was really impressed with these guys. Helped me order the correct garden door and then went to pick up extra bits when the order didn't turn up correctly, for no extra cost and couldn't have been nicer about it, even though it was a pain for them. Really cheerful and helpful - nothing was too much trouble. Would use them again, for sure.

Conversions - General- 17 Mar 2019
Elliott has to be the best decorator/ builder I have used. On time with works and no lies or excuses!!! After posting my job he call me within 30 minutes to arrange a visit. This was the following day. When Elliott arrived he understood my requirements and saw my ideas and advised when he thought from his experience, would work better. He was very polite and professional. I needed the work done within 2 weeks due to carpet being laid. He completed the works within 7 working days. The works involved, Removing a wall, Removing all woodwork, Boxing out pipes, Plastering, New coving, New skirting, New architrave 2 doors, Building an under stair shelving unit, Moving a socket, sky cables, internet box, Removing radiator, Painting of all new plastered walls ceiling and woodwork to my chosen colours. I was even able to get him to squeeze in some additional works. This was creating shelves in my airing cupboard upstairs and boxing out pipes in my hallway. Elliott’s communication throughout the works was great. Even if he was unable to get round my house he would let me know at his earliest opportunity. Very very tidy during works. I have a 3 year old and Elliott made sure it was left safe every night. The finished works are to a high standard and he even popped back to do a bit off snagging on a Saturday morning. When I say snagging it was a few paint marks, re-laying my old carpet and dropping my keys off. I will be using Elliott in the future.

What to ask a Dagenham extension builder before hiring?

What qualifications and experience do you have as an extension builder in Dagenham?

An extension builder in Dagenham should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Dagenham extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Dagenham?

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

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Dagenham extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
