Extensions- 16 Sep 2021
Very happy with the extension. Eddie and his team were best priced which was the reason we went with them, and he brought in a crack team of brickies, roofers and notable mention to the tilers.

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.

Kitchen Fitting- 8 Mar 2025
Spoke with Contempo and they stated they would be able to attend to do the job that evening as they would be in the area, they arrived at the time stated and carried out the works there and then as required and expected. Provided a demonstration of the fan working and also installed the cupboard door to the face of the extractor unit. Cleared up and charged the amount that was agreed. Great, reliable and professional service.

What to ask a Islington extension builder before hiring?

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

An extension builder in Islington 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 Islington 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 Islington?

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

How long will the extension take to complete?

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 Islington 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.
