James and his team of builders (quote Builders) gutted and fitted our bathroom. James helped us to choose fixtures and fittings ( which we were grateful for especially as the recomended shower we chose is AMAZING ) We were extremely impressed with his workmanship and found him and his team to be very professional, reliable and punctual. We have received great comments when family and friends visit and see our new bathroom, and we have recommended quote Builders to them. Thank you James and his team. Definitely using them to remodel our kitchen.

Extensions- 24 Apr 2021
Kujtim, working with his glazers, created a bespoke porch with a glass roof just as we asked. We were impressed with the finish of the internal plastering and Kujtim was able to come to our rescue one evening when we became locked outside the newly installed porch door. Although the project took longer than was anticipated we are happy with the quality of the finished product.

What to ask a Isleworth extension builder before hiring?

Before hiring an extension builder in Isleworth or extension building company in Isleworth, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Isleworth 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 Isleworth 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 Isleworth?

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 Isleworth 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 Isleworth 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.
