Extensions- 19 May 2019
Despite delivery difficulties caused by a separately instructed nominated subcontractor, Brian Verrall completed the work to an exceptionally high professional standard, on time and within the quoted price. His brickwork was exceptional on matching existing brick and joint detailing in all respects. He kept us informed at all stages throughout the work, started promptly every morning and kept the site as tidy as practical in a restricted area. We would have no compunction in using him again or recommending him to others.

Repointing- 14 Jun 2024
Joe and his Father are straight dealing, competent, honest and reliable. They did a very good job at a reasonable price. Joe's Father has decades of experience and knowledge and Joe had plenty of energy to attack the job. A third member of the team came in on the second day to help finish the job. A great combo! Repointing around the brickwork of 8 x windows with repair and repaint to window surrounds and masonry. Arrived on time! Finished on time! Cleaned up! Did the job to a high standard. This is not to be taken for granted in this trade and I had a couple of other chancers quote for the job who tried to phase me with very silly high prices at more than double the reasonable job value. So my recommendation is that you have Joe around to offer an honest quote and give this team preference and priority as a safe and satisfactory benchmark to get it done without fear of being ripped off or of having bodgers on the job. RECOMMEND RECOMMEND RECOMMEND!!

Joinery & Cabinet Making- 14 May 2021
James was absolutely brilliant. He did a brilliant job of creating some lovely fitted wardrobes in our very wobbly old house. James was super courteous to us, worked to schedule and adapted the design based on our requests. He was also really nice to the dog! We had a slight issue with the doors closing, to which he swiftly popped back to fix them and put it right no charge. I was super impressed with James' professionalism, dedication and quality of work and wouldn't hesitate to hire him again in future.

What to ask a Lewes extension builder before hiring?

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

An extension builder in Lewes 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 Lewes 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 Lewes?

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 Lewes 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 Lewes 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
