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

CAD / Drawings- 23 Sep 2020
Marius has been doing a great job and put in an extra effort to ensure we were happy with the outcome. I can not recommend Marius highly enough, especially as he managed to fix an issue with the council that we had from someone else drawings. He was patient and very well prepared. Went an extra mile and gave us different ideas/options. He was flexible with timings and most importantly with price. Had by far the best quote and did an exceptional job.

What to ask a Cobham extension builder before hiring?

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

An extension builder in Cobham 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 Cobham 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 Cobham?

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 Cobham 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 Cobham 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.
