When I was looking for quotes, Lukasz was the only builder who provided a fully detailed breakdown. From the start, he was professional and punctual, arriving exactly on time for our first meeting. He offered great recommendations on the best ways to approach the refurbishment and was flexible enough to let me source my own materials. Most importantly, he provides a warranty which he has already honored to fix a minor fault from another professional. It has been a pleasure trusting Lukasz and his team with my full house renovation.

Extensions- 19 Apr 2023
Lucian and his team are absolutely amazing nothing is ever a trouble for them we had no issues in terms of work schedule, quality of work and never had to chase them regarding anything. They took care of little things such as ensuring finishing is to great standard and making sure property was always left secured and clean at the end of every day. I have already agreed for Lucian to help me with landscaping my Garden. I would be comfortable to recommend him to friends and family and would say he is honest, fair and reasonable builder which is very rare specially in and around Leicester. Keep up the good work Lucian and all the very best.

What to ask a Kettering extension builder before hiring?

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

An extension builder in Kettering 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 Kettering 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 Kettering?

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 Kettering 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 Kettering 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.
