Extensions- 26 Sep 2025
MASSIVE thank you NBKS BUILDERS for the outstanding job completed for my Day Nursery. NBKS guttered our building and completed a full renovation and single storey extension in 3 & half months, and garden. Neil Director was a diamond from day 1 till end in his approach to our job, he always offered new ideas along the way, no request was to big or small, very adaptable. His Team was friendly, consistent, came every day including weekends to meet our September reopeing deadline. Neil is easy to speak with and project managers the full job. Neil has Exstended contractors who work alongside his team like electricians, plumbers, carpenters and together they worked on point to meet our deadlines. Even though NBKS have completed, they stay in touch to ensure alls working well, which this feels very supportive. NBKS came to our Nursery relaunch and open day, the High Sheriff Of Nottm was impressed with the build and the time frame completed in. We definitely recommend NBKS to all projects

Bricklaying- 8 Aug 2019
After the such short notice required for a bricklayer to attend my parents home the following day, Andrew contacted me within the hour to say he can fit them in between jobs and on the day they required. I wasnt around to meet Andrew and thank him but I can comment on the work he has done. The brick work and finish are outstanding and I will definitely be using him should I need any brickwork doing in the future. Thank you Andrew for helping my parents, and I shall look forward to seeing the final result. Cherie

What to ask a Selby extension builder before hiring?

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

An extension builder in Selby 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 Selby 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 Selby?

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 Selby 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 Selby 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.
