Electrical- 23 May 2019
C Hanlon have just completed the full rewire of the property and I am more than delighted with the quality of workmanship. Mark came out and surveyed / priced the job last week and whilst it was not the cheapest quote that I had, I progressed based on the fact that they were a local company who were able to start immediately and complete it quickly to a high standard. The job took only 2 days to complete and John, the Electrical Manager kept me fully informed throughout. I would have no hesitation on using C Hanlon again or recommending them to friends or family.

Fireplaces & Flues- 19 Jan 2023
Absolutely delighted with the work Alexander completed for me this week, just 6 days after we first spoke! He is clearly knowledgeable, took the time to give advice, and carried out works to a high standard at a very reasonable price. He responds quickly to queries and kept in touch throughout the job. Worked on to get my log burner installed even after discovering problems with my chimney. Really pleased, and discussed further works on my house for later in the year. Can't recommend highly enough. MyBuilder can be a gamble at times, but I wouldn't hesitate to hire again.

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.
