Extensions- 15 Jun 2024
My advice is avoid. Poor communication Poor workmanship Poor quality finish Create 'issues' during build to make you pay more than quoted Left project incomplete We pursued through the Court and won the case, but of course he is unable to pay, so we are pursing further through the Court. He will respond to the review with some excuse, but there is absoultley no excuse for poor workmanship and quality. Happy to share pictures and videos on request.

What to ask a Radlett extension builder before hiring?

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

An extension builder in Radlett 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 Radlett 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 Radlett?

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 Radlett 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 Radlett 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.
