Extensions- 25 Apr 2025
we recently had the pleasure of working with Leon building contractors limited, and i cant recommend them highly enough! They carried out a single story rear extension, an internal garage conversion and porch to the front of the house. On top of that they installed our new kitchen and toilet suite downstairs all finished to a high standard. From start to finish Vic and his team were amazing nothing was too much trouble and were always happy to do anything without a fuss. Their attention to detail was first class. It wasn't only us who was impressed but our neighbors commented how friendly, respectful and hard working they all were and have already asked for his contact details. Vic trade contacts also helped us with windows/bi-folds and quartz worktops all high quality at much cheaper prices i could find myself! Thanks again to Vic and the team for doing such a brilliant job, we have no hesitation to use again in the future!

Painting & Decorating- 6 Oct 2022
Very pleased with our choice. We initially got four quotes from different builders, most of them were terrible at communicating apart from Alfred. He was very easy to work with, responsive and very careful with our brand new house. His team was hard working, tidy and fast. They completely renovated our garden from removal of old decking and gravel to setting up new fences, levelling and turfing the ground. They also removed our old kitchen, partition wall and carpet, as well as did jobs like plastering, building a wall and set up lights and shelves. We’ll surely have him back soon to work on other jobs.

Extremely happy with the work JRE have done on our house. The quality of the finish is exceptional and the attention to detail throughout has been seriously impressive. One of the biggest things for me was how well everything was managed. The schedule was stuck to perfectly and communication was fantastic from start to finish, which can sometimes be hard to find with building work! I always knew what was happening and when, and if there was anything I wanted to change or make sure was done a certain way, nothing ever felt like too much trouble. The whole team were friendly, professional and constantly went above and beyond to make sure we were happy with everything. I’d have no hesitation recommending JRE and have actually already recommended them to friends. We’re so pleased with the refurbishment that we’ll be getting them back again soon for another bit of work. Great team, great quality and a really good experience from start to finish.

Bathroom Fitting- 15 Nov 2017
Mario was an absolute gem from start to finish. After a leak left our only bathroom out of action Mario came in and managed the full project to perfection (and also had a great tiler and electrician who did some other works). Six months on and I cannot fault any of the works. Highly recommended.

What to ask a Mitcham extension builder before hiring?

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

An extension builder in Mitcham 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 Mitcham 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 Mitcham?

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 Mitcham 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 Mitcham 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.
