Commercial Paving, Parking Lots, Excavation and Site Work in New Hampshire

Young's Excavating & Paving LLC completes parking lot paving, resurfacing, excavation, grading, drainage and site preparation work for commercial properties across six New Hampshire counties.

Commercial properties bring different access, drainage, surface and site conditions. The scope of a project should reflect those conditions and how the property is used, rather than follow a standard package.

The projects below show real work on parking areas, larger paved surfaces and commercial sites.

What a failing lot is actually telling you

Parking lots fail in patterns, and the pattern says what the fix is. Cracking in a grid across the whole surface is fatigue, which means the base is no longer carrying the load and an overlay will crack through within a season. A single settled area with water standing in it is a localised base failure, cut out and rebuilt rather than resurfaced. Cracks running in straight lines are usually shrinkage and are a maintenance job, not a construction one. Edges crumbling inward mean there is nothing holding the perimeter and the shoulder needs support.

Where a lot is sound but worn, an overlay is the economical answer, and the work that makes an overlay last is done at the edges. Milling the surface down at the entrance, along the curb line and at any doorway keeps the finished height the same, so thresholds still work, drainage still runs the right way and there is no lip at the road. A tack coat bonds the new layer to the old so the two act as one.

Accessible spaces are the part that gets missed on a restripe. Slope in an accessible space and its access aisle is regulated, and resurfacing changes slope. A lot that complied before an overlay does not automatically comply after one, so it is checked on the way out, not assumed.

Common questions about commercial paving

Can our lot be resurfaced, or does it need rebuilding?

It depends on the failure pattern. Grid cracking across the surface means the base has gone and an overlay will crack through it. Localised settling gets cut out and rebuilt. A sound but worn surface takes an overlay. The fastest way to know is a walk of the lot.

Can the work be phased so we stay open?

Yes. Lots are commonly done in sections so part of the parking stays usable throughout. Phasing gets planned around the business hours rather than the crew.

Does resurfacing affect accessible parking compliance?

It can. Resurfacing changes surface slope, and slope in accessible spaces and access aisles is regulated, so a lot that complied before may not after. It gets checked as part of the work rather than assumed.

A recent commercial project: Summit Title Services

Young's Excavating & Paving LLC completed parking lot repairs and resurfacing for Summit Title Services, in Bedford, New Hampshire, in May 2026.

Areas where the pavement had settled were cut out and rebuilt before the surrounding lot was prepared and resurfaced, so the repairs and the finished surface were completed as one scope of work.

What does the ADA require when a parking lot is resurfaced or restriped?

More than most property owners expect, and the trigger is lower than most people assume. The U.S. Department of Justice's guidance on restriping parking spaces is explicit that because restriping is inexpensive, bringing accessible spaces up to the 2010 ADA Standards is generally considered readily achievable when a lot is restriped.

The published requirements include:

  • A minimum number of accessible spaces scaled to the lot. One for a lot of 1 to 25 spaces, two for 26 to 50, three for 51 to 75, and upward from there.
  • At least one in every six accessible spaces must be van accessible.
  • A car accessible space must be at least 96 inches wide with a 60 inch access aisle. A van accessible space is either 132 inches wide with a 60 inch aisle, or 96 inches wide with a 96 inch aisle.
  • Accessible spaces and their access aisles must not slope more than 1:48 in any direction.
  • Spaces must sit on the shortest accessible route to an accessible entrance.

Why is accessible parking a grading problem and not a striping problem?

Because the two numbers pull against each other. An accessible space cannot slope more than 1:48, which is close to two percent. But the surface still needs roughly one to two percent of fall to drain at all.

That leaves a narrow window. Enough pitch to move water, not so much that the space fails the standard. A striping contractor cannot deliver that window with paint, and a paving contractor cannot deliver it if somebody else set the grade underneath. It has to be built that way from below.

To be clear about the boundary: the compliance obligation belongs to the property owner, and the design belongs to their architect or engineer. What Young's brings is the ability to build the grade to the numbers the design calls for, because the same company handles the excavation and the surface.

Commercial paving and site work

Every commercial property is a different combination of pavement condition, traffic, drainage and access. Some lots need repairs in isolated areas. Others are suited to resurfacing, and failed areas can need excavation and base work before new asphalt goes down.

Young's commercial work includes:

New asphalt for commercial parking areas, entrances and drive lanes, including preparation of the base and grade beneath the finished surface.

Resurfacing for suitable existing pavement, including preparation and transitions where new asphalt meets existing grades.

Excavation, grading and base preparation for paving projects, property improvements and new construction.

Saw-cut removal and rebuilding of failed areas when the problem runs below the visible surface.

Grading and drainage work within the project scope, to move water away from paved areas and vulnerable edges.

Sealcoating and pavement maintenance for commercial asphalt that is in suitable condition.
