Latest review:
We hired Lewis Building Ltd to remove an internal wall, rearrange our kitchen, fit bi-fold and patio doors, and make changes to other internal/external doors. The quote we were given was clear and concise and detailed all the work required and what it would cost. Initially, we were pleased with the structural work that was carried out but when it came to fitting the doors and the finishing of our kitchen we found the work to be sub-standard. Thomas then added extra costs onto the original quote for work that had not been agreed. When we questioned him about this he failed to return to complete the job. I have text, phoned and emailed and not had a reply. All work that was carried out was paid for so he does not have any incentive to return and finish or correct our job. I have taken extensive photographs of the finish left by Lewis Building Ltd, including gaps in the external doors, coving falling off the wall and large gaps in mitres. I even had to contact the skip company to have the skip removed as it was still in our driveway 4 weeks after Thomas failed to get back in touch with us. If you do intend to use these builders for work then be warned of extra costs added, not turning up when arranged, poor finishing, constant cleaning up after they have been and the potential of walking off the job.

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.

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.
