How much do contractors charge for grading drainage repair in New Brunswick?

Drainage grading repairs in New Brunswick typically range from $2,500-$4,000 for basic residential work, with more extensive projects reaching $8,000-$15,000 depending on the scope and site conditions.

Basic grading work around foundations runs $15-$25 per linear foot, while comprehensive drainage solutions including excavation, new weeping tile, and regrading can cost $35-$65 per linear foot. For a typical New Brunswick home, expect these ranges:

• Minor grading adjustments: $1,500-$3,500 (fixing slopes, adding topsoil, basic surface drainage)
• Foundation perimeter work: $4,000-$8,000 (excavation, membrane repair, new drainage stone)
• Complete drainage overhaul: $8,000-$18,000 (weeping tile replacement, sump pump installation, extensive regrading)

New Brunswick's challenging conditions significantly impact pricing. The province's clay soils, high water tables, and freeze-thaw cycles create persistent drainage issues, especially in areas like Riverview, parts of Moncton, and the Saint John River valley. Spring snowmelt and frequent rainfall make proper grading critical for basement protection.

What affects your costs includes property size, soil conditions, accessibility for equipment, and whether you need additional work like sump pump installation ($1,200-$2,500) or foundation waterproofing ($8,000-$15,000). Properties with steep slopes or limited equipment access can add 25-40% to base costs.

Timing matters significantly in New Brunswick's climate. Contractors can only do major excavation work from late April through October. Book early for spring work, as many homeowners discover drainage problems during snowmelt season. Winter emergency repairs cost 50-75% more due to frozen ground conditions.

Building permits aren't typically required for basic grading, but check with your municipality or Regional Service Commission if the work involves significant excavation near property lines or affects stormwater flow. Some communities have specific drainage bylaws, particularly in flood-prone areas along the Saint John River.

Most contractors include basic cleanup and seeding in their quotes, but extensive landscaping restoration adds $2-$8 per square foot. Always verify the contractor carries WorkSafeNB coverage - it's mandatory for employers with 3+ workers and protects you from liability.

Get multiple quotes and ensure contractors understand New Brunswick's specific drainage challenges. The best investment is often comprehensive work done once rather than repeated band-aid fixes that don't address underlying water table and soil issues.
