Roofing (Flat)- 9 Nov 2020
Darren & Son (plus Team) responded promptly to our advert for a Roofer in My Builder, they accessed the repair and quoted quickly. The work required was worst than expected but they tackled it with professionalism and speed and kept us informed of the work being done (via photos). They also cleaned up and disposed of all redundant waste. Thank you once again guys for being able to sort out what could have been a potential bigger problem and I would recommend then to anyone.

Restoration & Refurbishment- 2 Apr 2026
Really pleased I chose Leigh Matthews for this job. We were taking over a building that was unoccupied for 18 months and there were some issues with that, The team were excellent, and they finished the 4-week job on time, and right on budget. They were helpful and considerate and left the premises clean and tidy. They were also able to help out with some problems with the plumbing that were not in the original scope. I loved the way they did the estimate and the invoicing. Breaking all the items down into the individual tasks and at the end of each week, itemising which tasks were complete and a %age on those in progress. I would not hesitate to employ them again

What to ask a Crawley extension builder before hiring?

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

An extension builder in Crawley 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 Crawley 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 Crawley?

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 Crawley 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 Crawley 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.
