Extensions- 11 Jul 2018
Graham removed a lean to and replaced with a large brick extension to the back of the house and we are so pleased we hired him. The work started and progressed as expected and through the awful spring weather too! He finished look is great, the building inspector was really pleased with everything and as soon as had completed the extension we asked him to rip our old porch down and build a new one and luckily he had a week spare before a new job so cracked on with this too straight away. We would recommend Graham, he was hard working, tidy and just got on with it!

Nigel went out of his way to help me before Xmas, as my daughters room has been unusable since the storm a few weeks back. He fitted the work in to a time convenient for me, and all 3 lads were very helpful and friendly throughout, and also beat my other quotes. Thankyou Nigel and team, I will definitely recommend to others.

Lee converted our property from a 4-bedroom house into a 6-bedroom HMO, and he did an amazing job while keeping to the agreed 6-month timeline. Lee and his team delivered on every expectation at every stage of the project, which included a loft dormer conversion and a rear extension. They also completed six en-suite bathrooms, a new kitchen, a full rewire, plastering throughout, plumbing, joinery works, damp-proofing works, and installed new fire escape windows throughout the property. Lee managed the entire process professionally and ensured everything was signed off by Building Control. To date, Lee and his team have completed six properties for us, and we will continue to use them in the future because of their reliability, professionalism, and consistently high standard of workmanship. We would highly recommend Lee and his team to anyone looking for quality building work.

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

An extension builder in Alnwick 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 Alnwick 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 Alnwick?

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 Alnwick 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 Alnwick 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.
