Finish Grading — Southern NH
Finish Grading
Precision Results
Finish grading is the last earthwork step before a site becomes a finished property. It determines whether water drains away from your home or toward it, whether your lawn establishes, and whether your driveway holds its shape through NH winters.
Overview
Finish Grading in
Southern NH
Ridge Cut grades to a minimum 5% slope away from all foundations — six inches of fall in the first ten feet — and spreads topsoil to 4–6 inches for successful lawn establishment. Every surface is smoothed and checked before we leave.
From new construction completion to regrading around an existing home, Ridge Cut delivers precise finish grade across the service area, timed to NH's seeding windows in late spring and late summer.
Scope of Work
When Is Finish Grading Needed?
New Construction Completion
Topsoil restored and drainage slopes established once the structure is complete.
Post-Construction Lawn
Compacted subsoil needs topsoil and grading before a lawn can establish.
Drainage Correction
Soil settled against the foundation and ponding spots regraded to move water away.
Driveway & Parking Base
Proper cross-slope to eliminate icing and edge erosion on driveways and parking areas.
Landscaping Preparation
Major landscaping needs a proper finish grade established first.
Post-Stump-Grinding Restoration
Disturbed areas topsoiled and regraded after stump grinding.

Verification
Drainage slopes verified before we leave, with corrections made on site.
NH & ME Conditions
Finish Grading in NH:
Getting It Right
NH's frost heave, spring snowmelt, and thin native topsoil make finish grading more demanding than states with milder climates.
Heavy frost and spring snowmelt create real hydrostatic pressure. A minimum 5% grade away from all foundations is essential — we grade to it every time.
Native topsoil is often shallow, and construction sites may have almost none. We place a minimum of 4 inches, ideally 6, for successful establishment.
Late April through June and mid-August through mid-September. Ridge Cut advises on timing to maximize establishment success.
NH frost heave moves soil against foundations over time. Ridge Cut identifies regrading needs and corrects drainage slopes before damage occurs.

Frequently Asked
Questions
What is finish grading for new construction in NH?
Spreading topsoil, establishing drainage slopes away from the foundation, and creating a surface ready for seeding, sod, paving, or landscaping.
How much slope does a lawn need to drain properly?
A minimum 5% grade — six inches of fall over the first ten feet — away from the foundation. Beyond that, 1–2% is adequate for most lawns.
Do I need finish grading before seeding in NH?
Yes. Construction sites leave compacted, rocky, uneven subsoil that won't establish a lawn without finish grading and topsoil spreading.
When is the best time for finish grading in NH?
Late April through June, and mid-August through mid-September, to line up with NH's seeding windows.
Can you regrade around an existing home in NH?
Yes. Ridge Cut addresses settled soil against foundations, ponding areas, and uneven yard surfaces around established homes throughout the service area.
How much topsoil do I need for a lawn in NH?
A minimum of 4 inches, ideally 6. Ridge Cut verifies depth during finish grading and can source loam if the site lacks adequate topsoil.
