Bathroom Fitting- 17 Feb 2025
From start to finish the team was superb. Josh was helpful in suggesting ideas to make the most of the job. Bradley, Ray and Dave were all expert in their work and the job progressed quickly. Josh was excellent in communicating with us to advise who would be arriving the next day. As older clients we appreciated workers with whom we felt comfortable. The whole process gave us an ensuite to be proud of. Expert workmanship and a very pleasing finish. Would not hesitate to employ this contractor again.

What to ask a Longfield extension builder before hiring?

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

An extension builder in Longfield 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 Longfield 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 Longfield?

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 Longfield 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 Longfield 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.
