Extensions- 14 Jan 2019
Kevin did a good job overall with our extension. The build had many of the challenges that should be expected with an old, idiosyncratic house, plus a few others too. In particular, Kevin's wealth of knowledge and experience with traditional building methods was invaluable. His ability to solve problems and offer intelligent advice on many different aspects of the build was also hugely appreciated. The job took longer than expected but in the end the result has made it worthwhile.

What to ask a Maidstone extension builder before hiring?

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

An extension builder in Maidstone 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 Maidstone 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 Maidstone?

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 Maidstone 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 Maidstone 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.
