Latest review:
I got a good feeling as soon as I met Darren from Keystone. Sometimes, I find builders and tradespeople difficult to talk to but Darren was super friendly and chatty, as we went through my plans. Darren's input was really helpful and he and his team got the work done quickly and efficiently; also couldn't believe how tidy they were, thought there was going to be mess everywhere! Amazing job, at a really good price and great communication throughout...can't recommend highly enough.

Bee Builders built a conservatory-style extension to our house. It measures 15ft x 9ft with uPVC windows and double doors with a metal, long life sloping roof with two skylights. The build was completed to a very high standard. Stefan and his team were extremely professional, polite and demonstrated amazing attention to detail. The garden was left clear of all rubbish and the build was completed on time at a very competitive price - 5 star performance🥂

What to ask a Dunstable extension builder before hiring?

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

An extension builder in Dunstable 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 Dunstable 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 Dunstable?

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 Dunstable 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 Dunstable 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.
