Bathroom Fitting- 18 Jul 2019
Chris and his team have transformed our dingy bathroom into a lovely bright and clean space, replacing our boiler at the same time. He advised on what was possible to maximise space in our small bathroom and managed the whole process taking the hassle out of it for us. No issue was too big or small and Chris went beyond the call of duty to ensure we were happy. Letting strangers into your house can be worrying but I can’t speak highly enough of how respectful Chris an his team were. We’re so pleased with the final result, we’ve already lined Chris up for another job we need doing. Wouldn’t hesitate in recommending Flo.

Extensions- 14 Jun 2018
Andy Slimm agreed to build our retirement house. Unfortunately, six months later our dream has turned into a nightmare. For the early part of the build he was helpful and wanted to do a good job. He promised much and we trusted him with everything. When he went over the deadline he started to cut corners and build 'off plan’ in order to save money and try and finish. Suddenly, the day after we had parted with most of the final payment; he took his men off site without warning and abandoned us. We had to carry on renting as the house was unliveable. Three months later we have had to move into our unfinished home which is deemed “unsafe“ due to the mistakes that have been made. Multiple roof leaks, damaging the interior, creating damp and mould problems. Unfinished roof, drainage. Sewage smells in the house due to an unvented toilet system.2 metre deep/2 metre wide hole at the back of the house full of water, unfenced and uncovered. Building control have asked for his structural calculations where he did not build to architect's plans. We have requested many times that he come back, rectify/finish the work and provide the structural engineer's calculations. He refuses, so no other option but to use other builders and to sue Andy for damages. Such a sad and disastrous end to our dream. We have never written a negative review before, however, we feel strongly that we need to warn others as we do not want other clients to go through the traumatic time we have.

Plastering- 23 Nov 2025
Just had all my plastering work completed by Callum, a full Bathroom ceiling and lots of new electrical chases in 3 x additional rooms. Callum replied to my advert within an hour and he came and viewed the work and we agreed a rate within 2 days. Callum was very punctual and started work straight away by covering all our floors and carpets with plastic protectors. Callum was very polite and worked extremely hard all day without stopping, he also plastered in some additional areas adjacent to the areas that we agreed in the quote, which was great. Callum cleaned up and hovered in all the rooms when the work had been completed and left our house spotless The Finish of the plaster is fantastic and smooth. It’s a great job, well done and thank you. I wouldn’t hesitate to hire Callum again in the future and I will be definitely recommending Callum’s services to family and friends.

What to ask a Kent extension builder before hiring?

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

An extension builder in Kent 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 Kent 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 Kent?

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 Kent 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 Kent 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.
