What Does It Cost to Pave a Driveway in New Hampshire?
The cost of paving a driveway in New Hampshire is set by five things: how many square feet it is, what is already underneath it, how deep the new build has to go, how hard the site is to get a truck and a roller into, and whether the old surface has to come out first. Two quotes for the same driveway can differ by half, and almost always the difference is depth and base, not the asphalt itself. A quote that gives one number and no breakdown is not a quote you can compare to anything.
Why two quotes for the same driveway are not the same job
A driveway is not priced by area alone, though that is how most numbers get quoted. Area sets the tonnage of asphalt. Everything else sets whether that asphalt lasts eight years or twenty five.
The thing being priced is the whole assembly: the compacted gravel underneath, the fall that moves water off it, the edges, and then the surface on top. Asphalt is the last and thinnest part of it. A contractor quoting a thicker mat over an untouched base and a contractor quoting a thinner mat over a rebuilt base are selling two different products at a similar price, and the second one is the one still there in fifteen years.
The five things that move the number
1. Square footage, and what counts
Length times width gets you most of the way. What people forget is the apron where the driveway meets the road, the flare at the garage, and any turnaround or parking spur. Those are often a fifth of the total area and they are the parts that take the most abuse.
2. What is already there
Three starting conditions, three different jobs.
- Bare ground or a new build. Everything gets built from scratch: excavation, base, compaction, surface. Most expensive per square foot, longest to do, and the one where the base gets done properly because nothing is hiding it.
- An existing gravel drive. Sometimes the gravel is a usable base and sometimes it is six inches of loose stone over clay. Paving over a gravel driveway covers how that gets judged before it gets quoted.
- Failed asphalt. The fork that changes the price most, and the next section.
3. Overlay or full depth reclaim
If the cracking is confined to the top layer and the ground underneath has not moved, an overlay is the right call and the cheaper one. If the base has failed, an overlay telegraphs the old cracks through the new surface within a season or two and the money is gone. Full depth reclaim grinds the old surface into the base, re-grades it and compacts it, then paves over the result. It costs more and it is sometimes the only honest answer. Repave or excavate goes through how to tell which one a driveway needs.
4. Access
A driveway a paver and a ten wheeler can reach directly is cheaper to build than one behind a narrow gate, on a steep pitch, or a quarter mile up a wooded lot. Long runs mean more haul. Tight sites mean smaller equipment and more hand work. Neither is a problem, both are a cost.
5. Drainage, if it is needed
This is the line that surprises people. If the site has nowhere for water to go, the price includes getting it somewhere: a catch basin, a run of pipe, a swale, sometimes a culvert under the apron. It is not an upsell. A paved surface needs a consistent fall of about a quarter of an inch per foot to shed water reliably, and where that fall has nowhere to end the water sits, freezes and takes the driveway apart from underneath. Driveway drainage in New Hampshire covers where the water actually goes. Drainage decided after paving costs more than drainage decided before it.
How the arithmetic actually works
Asphalt is bought and laid by weight, not by area, which is why quotes are built from tonnage.
A rough working figure: one ton of compacted hot mix covers about 80 square feet at a two inch finished depth. So a 1,000 square foot driveway at two inches is in the region of twelve to thirteen tons of surface material, before anything underneath it. Change the depth and the tonnage changes proportionally. Change the base specification and a separate gravel figure appears alongside it.
That is the whole reason depth matters to price. An extra half inch across a large lot is real tonnage, and a contractor who quotes low and lays thin is not being generous.
What a written quote should itemize
A quote worth comparing separates:
- The area being paved, in square feet, including the apron and any flare or turnaround
- Whether the existing surface is being removed, ground and reclaimed, or paved over
- Base material and depth, stated separately from the surface
- Finished asphalt depth, and whether that figure is compacted or loose
- Any drainage work, itemized rather than folded in
- Edge treatment, and how the new surface meets the garage, the walkway and the street
- What happens to the spoil and the old material
If a quote is one number with none of that behind it, there is no way to know what is being bought, and no way to tell whether the cheaper of two quotes is cheaper or just thinner.
Does the season change the price?
Not usually the price, but it changes what is possible. Asphalt has to be laid and compacted while it is hot, and a mat that cools below working temperature cannot be brought back to density afterwards. Cold ground pulls the heat out of it faster. Late in the season that shortens the working window on any given day, and past a certain point in the autumn the honest answer is to wait for spring rather than lay a driveway that will not compact properly. When to pave a driveway in New Hampshire covers the season in detail.
Common questions about driveway cost
Is it cheaper to pave over an existing driveway?
Usually yes, and only when the base underneath is sound. Paving over a failed base is not cheaper, it is the same money spent twice, because the old cracks come back through the new surface within a season or two.
How much does it cost to pave a gravel driveway?
It depends entirely on whether the existing gravel is a usable base. Sometimes it is, and the job is mostly grading and paving. Sometimes it is loose stone over soft ground and the base has to be built properly first. That gets looked at before a number is given.
Why is my driveway quote so different from my neighbour’s?
Area, depth and base, in that order. Then access, and whether either job includes drainage. Two driveways of the same size on the same street can be genuinely different jobs.
Does a bigger driveway cost less per square foot?
Generally yes, because mobilisation, setup and haul are spread across more area. A very small driveway carries much the same setup cost as a medium one.
What adds cost that people do not expect?
Drainage where there is nowhere for water to go. Removing and disposing of a failed surface. Difficult access. A stamped or paver border. Fixing a settled apron where the driveway meets the road.
