Latest review:
The project lasted from July 2023 to Feb 2024 and comprised of: 1. Single story rear extension with new kitchen and underfloor heating 2. 75m2 patio 3. Internal reconfiguration including removal / installation of walls, new flooring, plumbing (including new boiler), new door frames, doors and skirting, redecoration, carpentry for cupboards 4. Ventilation of existing roof The team are both friendly and professional with Alin always on hand to manage any questions / situations as they arise. The work is clearly costed and every two weeks a valuation takes place to ensure transparency of work undertaken both in original scope and any extras. The quality of the build was excellent, something the building inspector commented on. Alin was recommended to me based on past work, and I in turn would highly recommend him.

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!

What to ask a Radlett extension builder before hiring?

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

An extension builder in Radlett 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 Radlett 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 Radlett?

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 Radlett 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 Radlett 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.
