Trufit Projects

Extension Builder in Crowthorne
After working for a family building company for 6 years and acquiring a City and Guilds in carpentry, I started trading in 2000. Worked building conservatories for 3 years before going alone. Started "Trufit Conservatories" which, after a couple of years, had grown to incorporate orangeries and extensions. The company changed its name to "Trufit Projects" to better suit the work now being offered and has since completed lots of extensions, as well as conversions and renovations.

Painting & Decorating- 14 Oct 2026
Filip and Patrick did a super job painting my children’s bedrooms. The level of prep was excellent and was quite challenging given it is in a period home. They were efficient, turned up exactly when they said they would and competitively priced. Definitely recommend and will be hiring for future work as well, thank you both!

Kitchen Fitting- 24 Oct 2025
Installation of new kitchen. Professional from start to finish. Klejdi made the whole experience of having a kitchen install a wonderful experience. No job seemed too difficult even when he ran into unforeseeable snags, he made me aware and just cracked on and did it at no extra cost. He has such an easy going personality which makes you feel comfortable having him around your home. The work that he had done was perfection. So pleased with the outcome that we asked if he happened to do tiling, to which he said he did. So had Klejdi to do this also. We had a difficult bit of wall to work with that he seemed to have no issues with. Again another job I’m very happy with. Thank you Klejdi and look forward to working with you again when I get the bathroom done.

What to ask a Crowthorne extension builder before hiring?

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

An extension builder in Crowthorne 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 Crowthorne 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 Crowthorne?

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 Crowthorne 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 Crowthorne 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.
