Conversions - General- 14 Feb 2026
Theo and his team recently carried out structural work at my property, removing a load-bearing wall and installing a 3-metre RSJ steel beam. The work was completed to a high standard and at an affordable price. They also took away all the rubbish, safely removed and capped a gas pipe into the ground, and removed unused sockets and a 2 fuse spurs, leaving everything clean and tidy. Theo was also extremely helpful in recommending other trusted tradesmen and suppliers, which was greatly appreciated. I would highly recommend Theo and his team.

Extensions- 20 May 2019
Dave and James have just completed our extension and open plan works and all I can say is amazing. We had lots of different quotes and it became more of an interview process than anything else and both Dave and James where really good at telling you what they planned to do and how it all works. I won't lie having an extension built is one of the most stressful things we have ever done but both guys helped every step of the way and there advice and knowledge was great. There quote was honest and fair and had no hidden costs, they even helped us keep costs down by trying to find us deals on kitchens etc... All the guys that work alongside them are also great Kevin, Mark the bricklayer and Brian the plasterer did an outstanding job. I can't recommend Buildcare Solutions highly enough.

Extensions- 15 Apr 2021
So delighted with the finished room, Jay had some great ideas and could visualise how it would look, which exceeded my expectations. Jay and Rhys are both highly skilled and very good at what they do, in particular the plastering and finished render looks fantastic. These works have transformed the outside area for me and with the patio laid to a high specification too I can’t wait to start using the garden again. Jay added steps and a low level wall that I hadn’t considered for the path and patio and this was so great to see as I hadn’t anticipated these elements looking so good. Thank you Jay and Rhys, really pleased with how it all came together. (I have also asked for some further works to be done based on my experience so far)

Can’t thank Neil and his team of workman enough for a really professional extension. From start to finish Neil kept us informed at every stage, including liaising with the Building Inspector at MBC. All of the work force were highly skilled and a pleasure to have around - nothing was too much trouble. Clean, tidy and very efficient. Have recommended Neil to other friends and would not hesitate to employ again!

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.
