Clear communication, high quality workmanship with minimal disruption - and on time and budget. It's obvious that David has exceptional building knowledge and high standards.

I used EBSW as the main contractor to install a new bathroom and separate toilet, as well as replastering some of the downstairs rooms. Prior to starting any work I met with Tom, and we talked through the different jobs, I was immediately impressed. We talked through different options and finishes and he took the time to explain each of the options. During the work we discovered an issue with damp, which turned a simple replastering job into something much more involved, again we talked through the options, and as it worked out he managed the different trades resulting in minimal additional hours (and cost). Throughout the building work, not only did Tom maintain my house as a tidy site, but he also ensured that disruption was minimised to the neighbours. A really motivated and enthusiastic company, I would highly recommend EBSW.

What to ask a Devon extension builder before hiring?

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

An extension builder in Devon 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 Devon 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 Devon?

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 Devon 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 Devon 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.
