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

Extensions- 15 Aug 2022
I had a good initial contact and they came out to do a first look pretty quickly. Wanted quoting on an extension, porch, driveway and side wall. In the end none of these jobs happened. A good experience to begin with. Porch - needed an architect (recommended by the builder), which took a couple of weeks to come and look then a few more weeks to get the drawings back to me. In the end, was too complex/costly due to the roofline. Fair enough - but took way too long to get to that answer. Extension - Initial 'rough' quote was very reasonable, but getting them to actually do a costed up quote took many weeks. In the end, the quote was >50% higher than the rough quote (scope of work hadn't changed). Driveway - Visited 4 times for this job. On 2 occasions, just didn't show up and couldn't get hold of them by phone. All of a sudden they came back 'online' and after 2 more visits, a quote came which was more than x2 the original rough quote. I appreciate cost of materials has increased but double was just too much. Side wall - Based on the other jobs being so difficult to progress, we decided to get someone else to sort it => 2 weeks after enquiry, the wall was built. In the end, we lost months for nothing and decided to not bother with 3/4 jobs. It's a shame, because they seem like a good bunch of lads and their references/pictures look great, but clearly have either too much work or need to hire someone to manage their time better.

Roofing (Pitched)- 3 Nov 2021
Isaac did several jobs, a reslate of the extension, house Krender and a new front canopy. Along the way, he uncovered elements of concern effecting the integrity of the house. I was kept updated and Isaac offered efficient solutions, making sure of reasonable pricing throughout. Issac has a team of workers, all of which were pleasant to liaise with, keeping the working site in order, as the jobs progressed. So pleased now, after all the work, to have confidence in how the house has been upgraded and has a bright fresh appearance.

Extensions- 28 Jun 2017
Do not let this man build anything more than a garden wall. He has left my extension in a right mess the porch roof, soffits, guttering, floor and electrics have all been condemned, some as dangerous, as well as some drainage and plumbing works being unfinished. There are sooo many problems the building inspectors are after him also trading standards are now involved.

What to ask a Leeds extension builder before hiring?

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

An extension builder in Leeds 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 Leeds 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 Leeds?

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 Leeds 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 Leeds 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.
