Bathroom Fitting- 17 Mar 2025
Gelu is hard working and dependent guy, will not fuss about the job like many do, but will crack on with it. Stayed late to finish it at many times. I am quite happy with the finish and work. shower fit, washbasin, toilet, tiling all done to my satisfaction. After seeing the work I asked him to do more like kitchen cabinets and skirtings.

What to ask a Finchley extension builder before hiring?

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

An extension builder in Finchley 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 Finchley 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 Finchley?

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 Finchley 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 Finchley 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.
