How do I compare quotes from wall insulation contractors in Campbellton to make sure I'm getting a fair price?

Getting multiple detailed quotes and understanding what's included is essential for comparing wall insulation proposals in Campbellton. Northern New Brunswick's harsh winters (5,200+ heating degree days) make proper wall insulation critical, so focus on quality and completeness rather than just the lowest price.

Request Detailed Scope Breakdowns

Every quote should specify the exact insulation method, materials, R-values, and coverage area. For wall insulation in Campbellton, you'll likely see quotes for dense-pack cellulose retrofit ($2.50-$4.50 per square foot), spray foam ($3.50-$7.00 per square foot for closed-cell), or exterior continuous insulation with new siding ($15,000-$35,000+ for a full home). Make sure each contractor measures and quotes the same wall areas — some include gable ends and dormers while others don't.

Ask specifically about vapour barrier work. In northern NB's cold climate, the vapour barrier must be on the warm (interior) side of the wall assembly. If your home needs vapour barrier repair or installation, this should be clearly itemized. Dense-pack cellulose contractors should explain how they'll access wall cavities (exterior holes vs. interior) and whether they're including air sealing around electrical boxes and penetrations.

Verify Insurance and Experience

Every contractor should provide proof of general liability insurance and ideally WorkSafeNB coverage. Ask specifically about their experience with your wall type — 1960s-1980s Campbellton homes often have 2x4 construction with minimal existing insulation, while newer homes may have 2x6 walls with batts that need upgrading. Spray foam contractors should have manufacturer training certifications, especially important given the chemical safety requirements and equipment complexity.

Compare Total Project Value

The cheapest quote often excludes critical components. Quality wall insulation in Campbellton should include pre-work air sealing (caulking gaps around windows, doors, and penetrations), proper vapour barrier installation or repair, and post-installation cleanup. Some contractors include blower door testing to verify air sealing effectiveness — valuable for quantifying the improvement and qualifying for NB Power rebates.

Understand Material Differences

Dense-pack cellulose at 3.5+ pounds per cubic foot provides both insulation (R-3.6 per inch) and significant air sealing when properly installed. Closed-cell spray foam offers higher R-value per inch (R-6 to R-7) and acts as both insulation and vapour barrier, but costs significantly more. Open-cell spray foam is less expensive but requires a separate vapour retarder in NB's climate. Make sure you're comparing equivalent R-values and performance, not just square footage prices.

Factor in Rebate Eligibility

Both NB Power's Total Home Energy Savings Program and the federal Greener Homes Grant offer rebates up to $5,000 each for wall insulation upgrades. However, you need a pre-retrofit EnerGuide evaluation before starting work. Ask contractors if they're familiar with rebate requirements and whether their proposed work qualifies. The rebate application process can offset 30-50% of your project cost, making a higher-quality installation more affordable.

Red Flags to Avoid

Be wary of quotes that seem unusually low — they often exclude vapour barrier work, air sealing, or proper dense-pack density. Avoid contractors who can't explain vapour barrier placement (it must be on the warm side in NB) or who suggest insulating over existing moisture problems without addressing the source. Door-to-door sales with "today only" pricing pressure is another red flag, especially for spray foam work where proper installation is critical.

Timing Considerations

Campbellton's northern location means a shorter construction season. Wall insulation work is best done during dry weather when contractors can properly seal exterior holes and manage moisture. Spring and fall are typically the busiest seasons, so winter quotes may be more competitive but weather-dependent for completion.

When to Hire a Professional

Wall insulation retrofit requires professional installation — dense-pack cellulose needs specialized blowing equipment and training to achieve proper density, while spray foam requires heated application equipment and chemical safety expertise. The consequences of poor vapour barrier installation or inadequate air sealing aren't visible until moisture problems develop inside the wall cavities.
