Highlights

"I recently had a loft extension done by Nick from NI Building Services, and I’m pleased with the result. Nick was friendly and easy to talk to, explained everything clearly and helped me understand what would work best for the space. He kept me updated, answered all my questions, and made the process feel easy. The quality of the work is great. the loft looks bright and spacious, and the new staircase fits perfectly. Nick also kept the place tidy and was very respectful of my home. I’m pleased with how the loft turned out, and I’d recommend Nick to anyone looking to have similar work"

"High quality work : ugly flat roof replaced by a beautiful slopped roof covering with tiles, downstairs windows and door , bathroom renovation delivered by a friendly & hard working team under Nick’s supervision - Nick is focused on delivering a very high quality work and will not hesitate to put suggestions forward for a better outcome, Overall very happy and will not hesitate to use Nick and his team again for future projects ."

"Nick completed a renovation project for us during the latter half of 2025. From the get-go it's clear that Nick is incredibly knowledgeable about his trade, and works to a high standard (and expects his crew to do the same). Communication was frequent, and Nick was always happy to walk us through his progress and discuss changes or add-ons to the plan (as usually happens with major jobs). Most valuably, Nick has an excellent network of tradespeople - when someone was needed for gas/asbestos/plumbing/windows, he already had someone lined up to speak with us. We'd gladly work with Nick again!"

Before you hire a builder

Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
Want an extra legitimacy check?
Run the Cowboy Checker on Ni Building Services Ltd before you contact them.
