Joinery & Cabinet Making- 16 Dec 2022
I'm so happy with shelving that ozzy and his colleague made. Ozzy took the time to understand want I wanted (floating alcove shelving) provided a clear and comprehensive quote, and kept me updated on completion of the shelving in his workshop. On day of installation, the guys were lovely and friendly, they went the extra mile in dealing with floors and walls that aren't at all straight, and the finished result blew me away, it's transformed the space completely. Such a pleasure to deal with, would highly recommend and i would definitely use them again in the future.

What to ask a Mottingham extension builder before hiring?

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

An extension builder in Mottingham 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 Mottingham 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 Mottingham?

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 Mottingham 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 Mottingham 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.
