Who We Are
The Sealcoating Company
Massachusetts Trusts
Cronin Sealcoating & Asphalt has been protecting driveways and parking lots across Massachusetts since 2000. We’re a local, owner-operated business — and that means when you call us, you’re talking to the people who will actually show up and do the work.
Honest Assessments
We don’t sell you services you don’t need. At every estimate, we evaluate your surface and tell you plainly what it requires — and what it doesn’t.
Premium Tarconite® Sealer
We use Tarconite® by Neyra — a professional-grade product that bonds firmly to asphalt and blocks water, oil, UV damage, and fuel spills. Not a hardware-store product. The real thing.
Local Expertise
We understand what Massachusetts weather does to pavement. The freeze-thaw cycles, the road salt, the spring thaws. Every job is tailored to the conditions your surface actually faces.
Guaranteed Work
When we prep your surface with our professional hot water power washing and degreaser system, we’re confident enough to back it with our one-year adherence guarantee — the only one offered in this area.

Spray and squeegee application of Tarconite® professional sealer restores your driveway’s finish and protects against water, UV rays, oil, and New England freeze-thaw damage.
For Homeowners →Crack Filling

We’ve Earned Our
Reputation the Hard Way
At Cronin Sealcoating, we’ve built our business on trust, craftsmanship, and a commitment to excellence — not the cheapest bid. Here’s what that means for your property.
25+ Years of Local Experience
We’ve been protecting Massachusetts pavement since 2000. That’s over two decades of learning exactly how New England weather, salt, and soil conditions affect asphalt — and how to prepare and seal surfaces so they hold up.
No Upselling. No Pressure.
We only recommend what your surface actually needs. If your driveway doesn’t need power washing, we’ll tell you. If your cracks are minor enough to go without filling, we’ll say so. Our customers trust us because we’ve always operated this way.
Owner-Operated & Community-Rooted
When you call Cronin, you’re talking to the people doing the work. We’re your neighbors — we live and work in the same towns you do, and our reputation in this community matters to us more than any single job.
A Track Record You Can Verify
Glowing reviews, repeat customers, and referrals across dozens of Massachusetts towns. Our reputation speaks for itself. We don’t just say we do great work — we can point you to neighbors who’ll confirm it.
