Joinery & Cabinet Making- 28 Oct 2022
Rafal was very helpful, and came up with alternative solutions to the job too from what I'd first suggested. He was prompt, cleaned up each day, and did a really good job which I'm very happy with. It was slightly worrying not to get a confirmed price for the work beforehand, just an estimate, but it turned out that was because it was hard to tell the time the job would take, and in the end what he did charge produced a really good result. I'd highly recommend him.

What qualifications and experience do you have as an extension builder in Borehamwood?

An extension builder in Borehamwood 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 Borehamwood 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 Borehamwood?

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 Borehamwood 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 Borehamwood 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.
