Asphalt Paving Company In New Hampshire

Five generations in NH paving means knowing that a driveway in Derry freezes differently than one in Portsmouth, and which soil types in Rockingham County push up in March. The person walking your property before writing your estimate learned that from someone who learned it the same way, not from a manufacturer's training session.

We run three year-round locations: Hampton at 548 Lafayette Road, Danville at 650 Main Street, and Wells, ME at 2196 Sanford Road. The crews who build your driveway are the same crews reachable in February. If you want to see finished work before calling, the project gallery shows NH jobs with before and after photos.

Most NH driveway failures start two feet below the finished surface, where the contractor skimped on base depth or skipped proper compaction. The asphalt on top looks fine for the first year. Then the base shifts through frost heave, the surface cracks along the weak points, and water gets in. By year three the homeowner is pricing replacement. The right driveway paving process excavates to frost-depth requirements specific to your site, compacts crushed stone base in measured lifts, and uses a binder grade rated for NH temperature ranges. A driveway built that way lasts 25 to 30 years. Most two-car driveways in NH run $3,000 to $10,000 depending on excavation depth, drainage corrections, and site access.

Commercial parking lots in NH deteriorate at the edges first. Water infiltrates where the asphalt meets the curb or grass line, freezes, and forces the edge apart from the inside. Most property managers notice when it looks bad. The structural failure started years earlier. Our commercial parking lot paving team corrects drainage and edge conditions during installation, not after. We handle everything from initial grading through compaction and parking lot line striping. For lots where the base is still intact, parking lot resurfacing costs 40 to 60 percent of full replacement and adds a decade to the surface. We assess the base before recommending either option and put that assessment in writing.

A hairline crack in August becomes a two-inch gap by April if you leave it through one NH winter. Water enters the crack in fall, freezes and expands by nine percent in January, forces the crack wider, and thaws without closing it back up. NH winters run that cycle 30 to 40 times. The crack that costs $40 to seal in September costs $400 to patch in May and $4,000 to resurface by year five. Our asphalt repair services cover crack repair, pothole repair, and full-depth patching at every stage of that damage progression. The right answer depends on how far the damage has reached, not which service generates the larger invoice.

Resurfacing is the right answer when your surface is worn but your base is structurally sound. It bonds a fresh layer of hot-mix asphalt to the existing surface for 40 to 60 percent of full replacement cost and adds ten or more years to pavement life. The part contractors do not always tell you is that resurfacing over a failed base does nothing. The new surface mirrors the failures underneath within one or two freeze cycles. We probe the base on every resurfacing estimate. If the base has failed and replacement is the only viable option, we say so before you commit to anything. When the base is good, asphalt driveway resurfacing and parking lot resurfacing both deliver real value.

Road salt strips asphalt binder faster in NH than most property owners expect. The first sign is graying. The surface loses its dark color, the binder starts oxidizing, and the edges begin shedding small aggregate. At that stage sealcoating slows the damage but cannot reverse it. Applied before the graying stage, it blocks salt from reaching the binder and extends pavement life by years. We offer driveway sealcoating and parking lot sealcoating across NH. Every application starts with a surface clean, crack fill, and any patching because sealing over an unprepared surface is cosmetic, not protective. Most NH properties need sealing every two to three years. The cost runs $0.15 to $0.25 per square foot.

Some surfaces have deteriorated past what a bonded overlay can address. Severe oxidation, delamination, or rutting from an incorrect mix spec require removing the damaged layer before any new asphalt goes down. Milling does that at a calibrated depth without disturbing the base below. Our asphalt milling contractor uses equipment that holds consistent cut depth across the full surface. All removed material gets recycled back into production mix, which reduces your cost per square foot on the resurfacing layer that follows. For commercial properties with high surface wear, milling and resurfacing together is more economical than repeated patching. More detail on our milling and recycling process is on the service page.

1. Free Site Assessment

A crew lead visits your property before any estimate goes on paper. We check drainage, probe the existing base, and note anything site-specific that affects the job. The visit takes 20 to 30 minutes and is free with no obligation.

2. Site Preparation & Excavation

We excavate to the depth NH frost conditions and your site's specific soil type require, not a generic residential template. Soft spots and failed sub-base material get removed. Drainage corrections happen at this stage before any base material goes in.

3. Base Installation & Compaction

Crushed stone base goes in and compacts in measured lifts. Each lift reaches the required density before the next one is added. On commercial jobs we run compaction verification before the asphalt phase starts.

4. Asphalt Paving

Hot-mix asphalt goes down with a binder grade rated for NH's cold-weather conditions. We track ground and air temperatures and do not push jobs into marginal weather windows to hit a date. If conditions are wrong the morning of a scheduled job, we reschedule.

5. Finishing & Final Inspection

Every completed job includes a written record: base depth, asphalt thickness, mix specification, and workmanship guarantee terms. The guarantee specifies what failure conditions qualify and how warranty work gets handled. Vague verbal guarantees disappear when you need them. Written ones do not.

Read the Estimate Before the Price

A written estimate from a legitimate asphalt paving company specifies base depth, asphalt thickness, what site prep is included, and what is not. If your quote lists a price without base preparation detail, ask for it in writing before signing. The contractor who resists putting the base spec on paper is not building to a base spec worth documenting. A quote delivered over the phone without a site visit carries the same problem: no contractor can accurately price an NH driveway without seeing the property.

Verify Licensing and Insurance First

Never hire a blacktop paving contractor without current NH licensing and liability insurance documentation. Ask for it before any conversation about scope or pricing. Any legitimate driveway paving company or parking lot paving company produces it immediately. Unlicensed work on your property means no recourse if equipment damages your structure and no coverage if a worker is injured on site.

Seasonal Crews Differ

NH paving season runs May through October. Crews that only operate in that window have no accountability for what happens after it closes. A driveway installed in August gets its first real test in December, and a workmanship guarantee from a contractor who is unreachable by then is theoretical. Pavemaster operates year-round from three NH and ME locations. The crew that builds your driveway is still reachable in February if a question comes up.

Verify Warranty Coverage

A real workmanship guarantee names the coverage period and the specific failure conditions it applies to. Vague language like 'we stand behind our work' with no terms attached is not a guarantee, it is a sentence. Ask what happens if the surface cracks in year two. If the answer is unclear or defensive, the guarantee will not hold up when you need it.
