Our Story
Started with a truck
and a work ethic.
Mack Seal was built from the ground up by one person with a straightforward belief: if you do great work and treat people right, everything else takes care of itself.
What started as a small operation in Bucks County has grown into one of the most trusted names in residential and commercial sealcoating in the area — not through advertising, but through referrals from satisfied neighbors, property managers, and HOA boards who've seen the difference firsthand.
As the sole owner and operator, every job gets personal attention from start to finish. There's no middleman, no subcontractors, no surprises. Just professional sealcoating done right.
What We Stand For
Our principles guide how
we do things.
Meet the Owner
The person behind
every job.
Colin Patterson
Owner & Operator · Mack Seal LLC
As the founder and sole operator of Mack Seal, Colin brings a hands-on approach to every project that larger paving companies simply can't match. When you hire Mack Seal, you get the owner — on-site, personally overseeing the work from prep through cleanup.
With over a decade of experience sealcoating driveways, parking lots, and commercial properties across Bucks County, he's seen every pavement problem imaginable — and knows exactly how to fix it right the first time.
"I take pride in every driveway like it's my own. If I wouldn't be satisfied with the result, the job isn't done."
Your best-looking
driveway awaits.
Free estimates. Fast scheduling. Work you'll be proud of.
