Extensions- 14 Jul 2021
Juro and his team completed a total refurbishment of our house that included removing all internal walls, along with a double story side extension, a huge job involving lots of steels, re-roofing, new construction, new bathrooms and kitchen, new windows and rendering along with all the plumbing and electrical work and decoration. They did the most incredible job, working efficiently, adapting to any problems that came along and working really hard to create the best finish possible at the budget we had. Despite the pandemic arriving just after the demolition stage, they didn’t miss a day on site, and worked tirelessly to get materials to keep the project moving. Incredibly they still managed to finish the project on schedule and to a standard that was exceptional. Juro is honest and upfront, didn’t ever add costs or ‘unforeseeables’ and was an absolute joy to work with. He also stuck to a very clear payment schedule that was easy to follow and always meant we only paid when we were absolutely 100% happy. My only reservation in writing this review is that I would like to selfishly hang on to him and keep his schedule clear for future jobs with family and friends!

What to ask a Balham extension builder before hiring?

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

An extension builder in Balham 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 Balham 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 Balham?

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 Balham 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 Balham 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.
