A family-run surfacing team built on craftsmanship and trust
Based in Castlewellan and led by owner Ciaran McMullan, CMC Surfacing and Groundwork Limited delivers tarmac, asphalt and block paving projects of every size across Belfast and all of Northern Ireland.
Local craftsmanship, done the right way
CMC Surfacing and Groundwork Limited was founded on a simple idea: that every tarmac driveway, block-paved patio and commercial car park should be laid to the same high standard, whether it's a small path at the back of a house or a full machine-laid car park for a local business.
Owner Ciaran McMullan has spent years working on surfacing projects across Northern Ireland and grew tired of seeing corners cut on sub-bases, rushed drainage and tarmac laid in the wrong conditions. CMC was set up to do it properly, every time — with honest prices, real communication and a finish you can genuinely be proud of.
From our base in Castlewellan we travel throughout Belfast, County Down, County Antrim and the wider Northern Ireland area. Most of our work comes through recommendations from happy customers — which is exactly the way we like it.
Simple values, high standards
These aren't marketing lines. They're the principles that decide how we run every job, from the first phone call to the final handover.
Quality first
We take the time to prep the ground, install proper drainage and use premium-grade materials — because shortcuts always show in the finish.
Honest & local
Owner-led and reputation-driven. Most of our work comes from word-of-mouth across County Down and Belfast — and we intend to keep it that way.
Fully guaranteed
We stand behind every job. Our workmanship is fully guaranteed and we're only a phone call away if you ever need us after the job is done.
Respect for your property
Clean, tidy sites — every day. We treat every project like it's our own home, from protecting planting to cleaning the road before we leave.
On time, on budget
Realistic timescales up front, clear communication during the job, and a final invoice that matches the quote. No surprises, ever.
Real people on site
You deal with Ciaran and the team directly. No call centres, no middlemen — just skilled tradespeople who care about the result.
