Extensions- 7 Oct 2015
Neil was brought in to construct a single storey extension to our house After trawling through numerous companies we were delighted to have found Neil as he is a bricklayer to trade unlike most other companies who are joiners who employ bricklayers and grounds workers and we know building an extension requires 80-90 percent brick and ground work and all other externals. From the moment my wife and I met Neil and his team we knew we had found the right builder. Right from the word go we could see the professionalism and after every day's work the site remained tidy.Communication was never an issue as we were always kept in the loop what was happening, when and where. Over all we are delighted that our extension came in at a good price, on time and and looks the way we wanted it too! Neil and his co worker Barry are two very friendly and easy to get on with guys. My wife child minds from home and this can cause a lot of problems when workmen come as we need to make sure the premises are kept safe and secure for the children.Neil and Barry always made sure that there was never any danger around and always maintained a high level of awareness making sure simple things like gates were closed and secured or any work areas were danger free. I also might add that all the kids thought that they were hilarious when they saw them and that in itself of making everyone feel at ease is one of many reasons why we will use Neil again and recommend him to anyone!

Zak has been in constant contact prior to the job being booked. On the day Zak called as he was able to arrive earlier than we had arranged which suited us perfectly. He was very polite and extremely professional throughout. We are really happy with the repair to our wall. Zak was very tidy and cleared everything away. I can’t recommend highly enough. It was a pleasure to have someone so professional.

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.
