Corinth Contractors from the beginning was a delight to work with upon our project. Some issues arose through the works as it was a fairly large project but quick solutions were presented! The service and quality of work was great and their project programme really helped us keep track throughout especially when we needed to supply items! Very happy with the final product and we have recommended to friends and family when/if they do their houses in the future.

What to ask a Walthamstow extension builder before hiring?

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

An extension builder in Walthamstow 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 Walthamstow 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 Walthamstow?

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 Walthamstow 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 Walthamstow 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.
