Extensions- 17 Apr 2019
We can't recommend Vince and Swift Design and Build highly enough. Vince made the impossible possible! He arrived on time and left the site clean and tidy at the end of every day. Vince had great suggestions to tweaks and changes we could make when problems arose, making us feel at ease during the whole project. We are very pleased with the end result and will definitely be recommending Vince to others. Thank you Vince!

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally.

Bricklaying- 19 Feb 2026
The work involved with the job was explained in plain language beforehand. All preparatory tasks such as dismantelling the old structure and clearing the site of rubble took place. The timescale for the job was kept to and the start and finish dates were kept to. I was impressed with the work carried out and will use the firm again when i need building work done.

What to ask a Reigate extension builder before hiring?

Before hiring an extension builder in Reigate or extension building company in Reigate, 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 Reigate?

An extension builder in Reigate 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 Reigate 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 Reigate?

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 Reigate 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 Reigate 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.
