Stone in Washington, NH

For driveways, 3/4u0022 crushed stone or 3/4u0022 minus (crushed stone with fines) makes a stable surface when compacted. For patios and walkways, 3/8u0022 to 1/2u0022 crushed stone or crushed stone screenings provide a smoother finish. For drainage, septic fields, and French drains, use clean, washed stone in the 1u0022 to 2u0022 range (no fines) to keep water flowing. Due to local glacial geology, color and texture may vary by supplier.

Freeze-thaw cycles can cause frost heave if water gets under the base and freezes, moving the stone and creating ruts. To reduce issues, build a well-compacted base (4-8u0022 of crushed stone), add a geotextile fabric where soil is soft, ensure good surface and subgrade drainage, and maintain a 2% crown on the driveway for runoff. Edge restraints and periodic regrading help keep the surface even through winter cycles.

Measure length and width to get square feet, multiply by desired depth in feet to get cubic feet, then divide by 27 to get cubic yards. For crushed stone, a good rule is 1 cubic yard ≈ 1.3 tons (approximate). Example: an 18' x 40' driveway at 4u0022 depth is 18x40x0.333 = 240 cubic feet = 8.9 cubic yards ≈ 11.6 tons, so you would order ~12 tons (round up for compaction and waste).

Prices vary with stone type, availability, and local delivery. In the West New Hampshire area you can generally expect crushed stone to fall roughly between $35 and $70 per ton depending on grade (washed vs. minus), but heavier or specialty stone can cost more.

Delivery alone typically depends on distance and tonnage; delivery fees in rural New Hampshire are often included for nearby suppliers but can run $50-$200 if outside local ranges. Contractor installation (grading, base prep, spreading, compaction) for a 2-car driveway commonly ranges from roughly $1,500 to $6,000 depending on existing site conditions, depth of base, and travel time. Get multiple local estimates and confirm what each quote includes (grade work, compaction, edge restraints).

Start with Hello Gravel to get instant local supplier options and delivery pricing for your zip code. For installation, check local contractor listings, ask the Washington town office or DPW for recommendations, and read recent customer reviews. Always verify contractor insurance, ask for references, and request a written scope that specifies material grade and compaction.

Washington is a small New Hampshire town, and there may be town zoning, driveway permit, or road frontage rules that affect driveway location, culvert requirements, and stormwater management. If you are in an association or historic district, check HOA guidelines or historic commission rules that may restrict visible surfacing or curb treatments. Contact Washington town hall or your HOA before starting work to confirm any permits or design rules.

Maintain stone surfaces by regrading low spots each spring, adding a 1u0022 to 2u0022 top dressing of crushed stone every 1-3 years as needed, and keeping drainage clear to prevent standing water. Control weeds with a combination of edging, landscape fabric under patios, and spot herbicide or hand removal; avoid overusing salt in winter as it can break down fines. Periodic compaction with a roller or plate compactor after adding material keeps the surface stable through freeze-thaw cycles.

Minimum Hello Gravel orders start at 3 tons, and deliveries arrive by dump truck (typically tri-axle); include clear drop-location notes and photos at checkout to avoid missed drops. Request a delivery date on the checkout calendar, ask about tailgate spreading during booking (driver discretion), and allow extra tons for compaction and waste when ordering for driveways or large projects.
