My wife and I have been truly impressed by Victor and Tom's quick turnaround and willingness to get the job done to an extremely high standard. Their men were friendly, efficient and tidy which is invaluable when taking on any new and daunting property project. As a result of their efficiency we are hoping to work with Victor and his team again in the coming months and would highly recommend them to anyone looking for a reliable and professional contractor.

Painting & Decorating- 13 Sep 2026
Fantastic service from Swiftfix. They painted and decorated my entire flat and did an excellent job from start to finish. Everything was completed to a very high standard, and they were professional, reliable and easy to deal with throughout. The price was also very reasonable for the amount and quality of work involved. I’m extremely happy with the finished result and would definitely recommend them to anyone looking for a professional painter and decorator.

What to ask a West Ham extension builder before hiring?

Before hiring an extension builder in West Ham or extension building company in West Ham, 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 West Ham?

An extension builder in West Ham 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 West Ham 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 West Ham?

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 West Ham 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 West Ham 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.
