Windows & Doors (uPVC & Metal)- 7 May 2026
Following contact with the trader and resolution of the initial communication issues, this review has been updated as a temporary placeholder while works are ongoing. At present, the customer has confirmed that communication has resumed and the project is proceeding as agreed. As the works have not yet been completed, a final review cannot fairly be given at this stage. The customer remains hopeful that, upon successful completion of the project, this review can be updated to reflect the full experience positively.

Karl at KT Building Services did a great job replacing a damaged post and fence panel in my garden. He arrived on time, got straight to work and hauled away all the rubbish. I would definitely use his services again and would recommend him to all.

Extensions- 14 Nov 2019
Bogdan himself is extremely knowledgable and his years of experience in industry is clear to see, which makes choosing him great value for money. Before and during the project he offered solutions that we hadn't considered and the would in fact save us money and be of benefit to us in the future. His team is punctual, reliable, diligent, speedy and clean! They take pride in their work which has led to a highly satisfactory work in the final build. Bogdan also has great connections to third parties (e.g. to flooring and curtains/blinds providers) which is very valuable, especially when trying to coordinate different aspects and timings of a full house redecoration. His quotes and payment structures are fair, clear and concise which is also very helpful. His communication is excellent too. All in all, Bogdan's great work took away a huge amount of stress during these projects. I would highly recommend Bogdan and his team for any prospective works someone is considering.

What to ask a Crawley extension builder before hiring?

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

An extension builder in Crawley 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 Crawley 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 Crawley?

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 Crawley 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 Crawley 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.
