How much for lawn grading and seeding in NB?

Lawn grading and seeding in New Brunswick typically costs $2-4 per square foot for basic grading with premium seed, or $1,500-6,000+ for an average residential lot depending on the scope of work needed.

The cost varies significantly based on how much grading is required. Light grading to smooth minor bumps and low spots runs $1.50-2.50 per square foot including seeding. Moderate grading to fix drainage issues or level uneven areas costs $2.50-4.00 per square foot. Heavy grading requiring soil removal, importation of topsoil, or significant slope changes can reach $4-8 per square foot before seeding.

Seeding alone (assuming the grade is already acceptable) costs $0.75-1.50 per square foot in NB, including premium grass seed blend suitable for our Zone 4-5 climate, starter fertilizer, and straw mulch. Most contractors use a blend of 60% Kentucky Bluegrass, 20% Fine Fescue, and 20% Perennial Ryegrass - this combination handles our Maritime humidity, winter conditions, and varying sun/shade conditions across New Brunswick properties.

Timing is critical for success in our climate. The best window for seeding is late August through mid-September when soil is still warm (promoting germination) but cooler weather and fall rains help establishment before winter. Spring seeding (late May after soil reaches 10°C) works but requires more irrigation through our sometimes-dry summers.

Additional costs to consider: soil testing ($50-100), lime application if your soil is acidic like most NB soils ($100-200), and irrigation for the first 6-8 weeks ($200-400 if you don't have existing sprinklers). Many NB contractors include basic soil amendment in their pricing, but severely compacted clay soils common in the Fredericton area or sandy coastal soils may need extra organic matter.

For DIY consideration: Homeowners can handle light grading with a rake and seeding on areas under 1,000 square feet. However, hire a professional for significant grade changes, drainage corrections, or areas over 2,000 square feet. Proper grading affects water flow toward your foundation and neighboring properties - mistakes here create expensive problems later.

Most reputable contractors provide a one-year establishment guarantee, meaning they'll overseed thin areas the following spring at no charge. Always verify the contractor carries liability insurance and WorkSafeNB coverage before starting work.
