CAD / Drawings- 11 Dec 2025
We were looking at mixed use property that had some serious structural issues, it was a significant size and therefore had a lot of potential layouts. Lee was very clear about how he could assist us, professional in his communication and in attending the property when he said he would. Ultimately we didn't proceed with the purchase due to the insight we gained from Lee and our survey but I would definitely recommend and use Lee in future.

Bricklaying- 2 Oct 2018
Carl was very professional and friendly from start to finish. We needed the job doing fairly quickly and Carl did just that...responded to the ad very quickly,he came to price up on a Sunday afternoon and it was completed on the following Wednesday. The price was very reasonable and we were happy to go ahead. He was helpful, knowledgeable, nothing was too much trouble and he cleaned up afterwards. The job was completed to a high standard and we wouldn't hesitate to recommend or call him back for any other work we may need in the future. Great job Carl!

What to ask a Middlesbrough extension builder before hiring?

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

An extension builder in Middlesbrough 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 Middlesbrough 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 Middlesbrough?

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 Middlesbrough 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 Middlesbrough 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.
