Is it cheaper to install sod or seed a new lawn in New Brunswick?

Seeding is significantly cheaper upfront — roughly 60-75% less than sod installation — but sod delivers an instant lawn and carries less risk of failure. For a typical 3,000 square foot New Brunswick lawn, seeding costs $600-$1,500 while sodding the same area runs $6,000-$10,500 installed, making the price difference substantial.

The cost breakdown for seeding includes quality grass seed at $4-8 per pound (you'll need 6-9 pounds per 1,000 square feet, so roughly $70-$200 in seed), starter fertilizer ($30-$50), topsoil or compost for topdressing ($200-$500), and optional straw or erosion blanket ($50-$150). If you hire a professional to prepare the seedbed, grade, seed, and apply starter amendments, expect to pay $0.20-$0.50 per square foot, bringing the total for 3,000 square feet to $600-$1,500. DIY seeding can cut costs to $300-$700 for materials alone.

Sod costs $2.00-$3.50 per square foot installed in New Brunswick, which includes the sod itself, delivery, soil preparation, grading, and professional installation. The sod material alone costs $0.50-$1.00 per square foot from NB suppliers, with the remainder covering labour, soil prep, and equipment. For 3,000 square feet, you're looking at $6,000-$10,500 total — a premium, but you walk away with a fully established lawn the same day.

The hidden costs of seeding often narrow the gap more than homeowners expect. Seeded lawns in New Brunswick take 8-12 weeks to establish and may need overseeding in thin areas the following fall, adding another $100-$200 per 1,000 square feet. You'll use significantly more water during the 3-4 week germination period (watering twice daily), and there's genuine risk of washout during heavy Maritime rainfall events. Erosion on sloped properties near Fredericton's hills or Saint John's coastal terrain can wash away seed entirely, requiring reapplication.

The best timing also differs. Sod can be installed from May through October in most of New Brunswick, though spring and early fall are ideal. Seeding is most successful in a narrow September window when soil temperatures are warm, competition from weeds is low, and fall rains provide natural moisture. Spring seeding (late May) is riskier due to weed competition and summer heat stress on young seedlings.

For most NB homeowners, the practical recommendation depends on budget, timeline, and property conditions. If budget is tight and you're patient, seed your lawn in September using a 60% Kentucky Bluegrass, 20% Fine Fescue, 20% Perennial Ryegrass blend and accept that it will take a full year to fully mature. If you need an instant lawn, have a sloped property prone to erosion, or are on a tight timeline (selling a home, hosting an event), sod is worth the premium investment.
