Latest review:
Completing our scope with Insight ProBuild from start to finish was one of the most least stressful projects we have ever completed. From start to finish, Anil was on hand generating creative ideas/suggestions, providing clear and achievable plans/schedules, and managing the scope to our agreed budget. Overall, Anil earned our trust through careful management of the Project, handling all the interfaces and taking the stress away from us, having a clear eye for detail and quality of his product, excellent communication through regular engagement with us and ultimately delivering a high-quality Project in the end. Even after completion, Anil was excellent by following up on any issues and ensuring we were still happy with the completed scope. Would recommend Insight ProBuild as Anil genuinely cares about his product and prioritising the relationship with his clients to ensure they are satisfied and happy.

Extensions- 26 Nov 2020
Paul was absolutely great to work with on our project. I would have no hesitations in hiring him and his team again, which we plan to do. He was great as the plans changed, and when unexpected things cropped up he communicated with us really clearly and promptly. The quality of the work is really high, and even as there have been (really) minor snags to deal with after he's been great about these too.

What to ask a Canonbury extension builder before hiring?

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

An extension builder in Canonbury 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 Canonbury 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 Canonbury?

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 Canonbury 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 Canonbury 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.
