I cannot thank Jay at Inspire Kitchens & Bathrooms enough for his help. Really lovely team. They were quick to quote and cheaper than many. His work was quality and completed on time. I will highly recommend Inspire Top quality. I will be hiring them again soon to refurbish our bathroom on our next project.

Extensions- 1 Sep 2021
I have nothing but praise for Michael and his team. The project was managed exceptionally well and Michael kept us apprised of progress, emerging issues (which were dealt with quickly and with some innovative thinking) and he was honest and candid with our choice of kitchen tile (I think his words were do you want to rethink that colour!). Michael quoted in Nov and started work in the Spring (late Mar) and held his price despite a national increase in the price of materials and reduced availability which he managed admirably. Obviously a man with a good eye; his suggestions for additional works were inspired and they have resulted in a high quality finish. Finally, it is worth mentioning the team who did the grafting! Very industrious, skilled, polite and helpful. Highly recommend Wooburn PM to anyone considering building work. :-)

Gas Work- 5 Jun 2025
Arjun seemed like a very nice guy. He visited the property to inspect the issue and prepare a quote, and he even kindly brought me some homemade Indian food (!). I paid him a £130 deposit to cover the cost of materials, but unfortunately, he never returned to complete the work. He has not provided a receipt for the parts he claimed to have purchased, and he is no longer answering my calls. It’s very disappointing, and I’ll now need to find another plumber.

I am an engineering consultant and property investor, so Im picky about who I will work with. I've worked with Ecofit over 5 major extensions, conversions or complete back to brick refurbishments over the last 7 years, and dozens of smaller jobs. I am really happy with their service, they are superb! I will continue to work with them and can strongly recommend them.

What to ask a Thame extension builder before hiring?

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

An extension builder in Thame 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 Thame 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 Thame?

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 Thame 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 Thame 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.
