Groundwork & Foundations- 18 Jul 2019
My wife and I have been truly impressed by Victor and Tom's quick turnaround and willingness to get the job done to an extremely high standard. Their men were friendly, efficient and tidy which is invaluable when taking on any new and daunting property project. As a result of their efficiency we are hoping to work with Victor and his team again in the coming months and would highly recommend them to anyone looking for a reliable and professional contractor.

What to ask a Harringay extension builder before hiring?

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

An extension builder in Harringay 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 Harringay 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 Harringay?

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 Harringay 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 Harringay 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.
