Extensions- 29 Nov 2023
We had the most fantastic experience with Sarunas. He was highly professional from start to finish and completed the work to the highest standard. We extended our project significantly once we realised how excellent he was and he has now renovated our whole home over an 18 month period. He was able to guide us through the process and help us make key decisions which made the experience smooth and efficient. He is extremely skilled in all aspects of building, has high attention to detail and is a pleasure to have in your home! I couldn't recommend him higher and look forward to having him back in future to convert our loft!

Groundwork & Foundations- 1 Oct 2024
It was a complex job requiring the removal of an earth bank, ground works to include reinforcements to an independent engineer's specification, and re-erection of a boundary wall in a locally listed area against a busy road. We had some problems during the works but all were resolved to mutual satisfaction and with good humor. The end result is a high quality, solid wall of which Dave and his team should be proud

An incredibly positive experience from start to finish. I found Robbie and team were hard workers, very likeable and provided brilliant results. Comms throughout were excellent. With Robbie happy to discuss the job over the phone beforehand and put our minds at ease. A big shout out to the team for undertaking this work during COVID. We understand the pressures this places on our tradespeople and we thank Robbie and his team for their diligence and commitment to wearing masks in our home and working safely.

Painting & Decorating- 6 Apr 2026
I had a very positive experience working with Konstantinos. He is personable, reliable, professional and excellent at co-operating throughout the process. He repainted my entire flat/walls/ceilings to a high standard (and sanded down) he also helped address a few additional repairs along the way. The finish is clean, fresh, and has completely transformed the space. He was thorough and ensured everything was completed properly and on time. I particularly appreciated his attention to detail and his proactive approach in taking care of things I hadn’t even noticed. I would happily recommend Konstantinos and would work with him again in the future! Thank you

The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!

Kitchen Fitting- 7 Jun 2020
We liked Alex from the first meeting and the first impression was spot on. Alex did an amazing job on our kitchen, which was half initiated by another tradesman. He reviewed the work and fixed many issues, always explaining and communicating well. Our kitchen had to be adapted and had some non standard cabinets but Alex was able to do all the additional features we asked for and with a great result. He also recommended some design changes which we agreed to and love. He finished the work, reviewed everything and signed off, always with a smile which is a plus. Definitely highly recommended and we will call him again in the future for sure. Thank you Alex!

What to ask a Westerham extension builder before hiring?

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

An extension builder in Westerham 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 Westerham 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 Westerham?

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 Westerham 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 Westerham 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
