Didn't finish the job and cut communication despite paying up. Took 9 weeks to not even complete a small bathroom. We're now left with an unfinished room having paid over what was quoted.

Conversions - General- 26 May 2010
Thanks to Lester and Chris, all work completed, very easy to work with and any questions/queries we had were always addressed. Left the place tidy each time and kept us informed of what was happening. Last few little bits tidied up and any problems have been told to get in touch with them. Out of four builders contacted on here only Lester turned up to quote and once his quote was approved he rang to organise start date, they were here every morning at 8am without fail. Really pleased with end result, thank you.

With having more than 25 years within the groundwork's/construction industry, also working alongside large 'Blue Chip' companies Nationally I consistently witnessed weak communications between contractors and the client. It was at this point I decided to form a small building company that stood alone, and at the fore front was to deliver our customer their project from concept through to completion while giving total support/advice and excellent communication throughout the whole process.

Carpentry- 17 Dec 2025
Top man is Laurence. A small job turned into roughly 3-4 months of work across more than one property. Great builder too who is adept in most areas from bricklaying, rendering, plastering, building furniture, woodwork and just about everything in-between. Capable in most aspects of building. Not your typical builder and a genuinely lovely guy nd very knowledgeable.

What to ask a Calne extension builder before hiring?

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

An extension builder in Calne 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 Calne 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 Calne?

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 Calne 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 Calne 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.
