Kitchen Fitting- 16 Nov 2018
I can honestly say I would highly recommend Jake for any work required, he oversaw and managed all work needed, dealt with everything. The work he and his company have done in my kitchen was completed to a high standard and I am extremely happy with the finished transformation. I cannot thank Jake enough for the way he dealt with the deliveries and when parts not arriving dealing with the 3rd party, allowing me to continue working throughout the time it took for my kitchen to be done. My mind was at ease throughout the project that all was being dealt with. So thanks again

Extensions- 10 Jan 2016
We are delighted with the fantastic single storey extension that Rob and his team have built for us, creating a wonderful kitchen/diner/lounge and utility. Nothing was too much trouble for them and their dedication to providing a home we wanted (not what was easier for them) was excellent. They were punctual, competent, polite, hard working, tidy and fun to have around. They provided good ideas to help us through any difficulties we had in making decisions on areas we hadn't thought about when planning the extension. The build has been finished to a high standard and we now have the living area that we have always wanted. Everybody who visits is impressed with the work and has asked for Centurion's details. Thank you Rob, Paul and Martin for our fabulous new home.

What to ask a Newnham extension builder before hiring?

What qualifications and experience do you have as an extension builder in Newnham?

An extension builder in Newnham 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 Newnham 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 Newnham?

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 Newnham 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 Newnham 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.
