Extensions- 4 Nov 2021
Absolutely superb service from start to finish. Chris managed the work with complete professionalism and always kept me informed along the way. Chris worked extremely hard to get the extension completed on time and always left the site in immaculate condition during the build. Chris has a real attention to detail which can be seen in his quality workmanship. I will not hesitate to use a Chris again in the future and I highly recommend him.

If you want a tradesman who takes pride in his work look no further, very polite friendly and tidy but his work is second to none, you wont find any faults with his workmanship which is hard to find these days with so many cowboys out there, I would highly recommend John Kerry and would like to thank him once again for one hell of a excellent job.

What to ask a Thirsk extension builder before hiring?

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

An extension builder in Thirsk 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 Thirsk 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 Thirsk?

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 Thirsk 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 Thirsk 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
