Paul was great. Easy regular comms. Arrived early on the day and fit me in as best he could. Straight to it, great work, very professional and sorted out some other problems as they were discovered. Talked me through options and did what was asked to a very high finish. Would highly recommend and use again.

I started in construction as a apprentice carpenter, several years later I launched my own company focusing on loft conversion and extensions in Ascot. 5 years ago I started property developing in Ascot, then 2 years ago I saw a building at auction in Bath and feel in love with it, I won the building at auction and renovated it into 3 apartments, this year I have built a new build home in Bath which is being sold. I am now relocating back to Berkshire and looking to take on one build.

Conversions - General- 22 Jun 2026
Bled from BSM was fantastic from the start of the job to the finish. His pricing was fair, and he turned up each day on time, and left everything tidy each day. Nothing was too much effort, and the quality of the work was outstanding. I would have no hesitation in recommending him to anyone else.

What to ask a Slough extension builder before hiring?

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

An extension builder in Slough 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 Slough 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 Slough?

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 Slough 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 Slough 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.
