Handyman- 26 Sep 2024
A extendable curtain pole to put up. There was a problem with the actual pole, manufacturing problem. Put up the three brackets and I will purchase a new pole and fit myself. Initially he said only one screw was enough for the three brackets but I insisted two screws for bracket, he didn’t centre the middle bracket and used a pencil for a measurement, I suggested a measuring tape. Wrong type of screws and missing plasterboard fixings and when the pole was installed the middle bracket started to fall off, so I had to get someone to fix it. He did two fixings of two vertical blinds and they were fine

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.

What to ask a Renfrew extension builder before hiring?

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

An extension builder in Renfrew 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 Renfrew 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 Renfrew?

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 Renfrew 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 Renfrew 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.
