Extensions- 18 Feb 2021
Michael and Neil did a fantastic job with our large 2-story extension. I would happily recommend them for any building work. Our build was not straight forward and the brothers displayed skill, experience and patience when extending alongside a building built in the 1800s. They were professional throughout the whole process as well as very hardworking, punctual and even working weekends to get the job finished for us as soon as possible. We had many changes along the way that differed from the original drawings to which they were more than accommodating and provided competitive prices. As the construction was being held during the Covid pandemic the brothers kept us duly informed throughout with any supply or material delays alleviating any worries we had.

Carpentry- 5 May 2025
We needed a radiator moved and a new one installed whilst minimising damage to our wooden floors. Fantastic work from the start, brilliant communication, and Michael went through very clearly what was needed and any issues that might come up, and had great advice. The job was done in a morning with no stress and a friendly manner. And was very pleased with our new radiator in place with minimal damage done to the floors and a clean space. Will definitely be calling on again and highly recommend to others.

What to ask a Glasgow extension builder before hiring?

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

An extension builder in Glasgow 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 Glasgow 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 Glasgow?

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 Glasgow 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 Glasgow 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.
