Why 603 Asphalt
THE 603 DIFFERENCE
We're not the biggest paving company in NH — we're the one that cares most about getting it right. Every job. Every time.
Craftsman-Level Work
Every job is finished to the same standard we'd want on our own property — clean edges, proper grade, and a surface that lasts.
Premium Materials Only
We never cut corners on mix quality or base depth. The right materials installed correctly is the only way we know how to work.
On-Time, Every Time
We show up when we say we will, finish when we say we will, and leave the site cleaner than we found it.
Licensed & Fully Insured
Fully licensed, bonded, and insured in NH and MA. You're protected on every job, no exceptions.
Honest Estimates
No bait-and-switch pricing. What we quote is what you pay — with a clear scope of work before we ever break ground.
We Stand Behind Our Work
If something isn't right, we make it right. Our reputation in this community is everything to us.
Our Standard
PRIDE IN EVERY
SQUARE FOOT.
When you hire 603 Asphalt, you're not getting a crew that's just trying to get to the next job. You're getting tradespeople who take real pride in their craft — who notice the details, do the prep work right, and won't leave until the job looks exactly the way it should.
That means proper base preparation before a single shovel of asphalt goes down. It means clean, defined edges. It means the right mix for the application, compacted correctly, graded so water drains away from your home. It means a finished surface you'll be proud to pull into every day.
"We treat every driveway like it's our own. If we wouldn't be proud to park in front of it, it's not done."
— Clark, Owner, 603 Asphalt

Common Questions
FAQ
How much does asphalt driveway paving cost in NH?
Most residential driveways on the NH Seacoast run between $3–$7 per square foot depending on size, grading needs, and existing conditions. We provide free, detailed estimates so you know exactly what to expect before any work begins.
How long does a new asphalt driveway last?
A properly installed asphalt driveway lasts 20–30 years in New Hampshire with regular maintenance — sealcoating every 2–3 years and prompt crack repairs keep it performing like new.
How soon can I use my driveway after paving?
You can walk on it within a few hours. We recommend waiting 24–48 hours before driving on it, and avoiding heavy vehicles for the first 2 weeks while the asphalt fully cures.
