Should I get multiple quotes for spray foam insulation in Fredericton, and how many contractors should I contact?

Yes, absolutely get multiple quotes — and for spray foam specifically, you should contact at least three contractors, ideally four or five. Spray foam is one of the most variable-priced trades in New Brunswick, and the differences between quotes are not just about price — they reflect significant differences in equipment quality, material formulations, installer experience, and application thickness.

Why Spray Foam Quotes Vary So Much

Spray foam pricing in the Fredericton market can vary 30-50% for identical square footage, and that spread is wider than almost any other insulation type. The reasons are legitimate: spray foam requires heated proportioning equipment (rigs that can cost $50,000-$150,000), specialized training, and chemical components (A and B sides) that vary in quality between suppliers. A contractor running a well-maintained, properly calibrated rig with premium materials will quote differently than someone with older equipment or lower-cost chemicals — and that difference shows up in the finished product, not just the invoice.

The most important thing to understand is that spray foam quotes are not apples-to-apples unless you specify the same application thickness and density. A quote for 1.5 inches of closed-cell foam and a quote for 3 inches of closed-cell foam are completely different products delivering completely different R-values (roughly R-10 versus R-20). When you contact contractors, tell each one exactly what you need — the location (rim joists, basement walls, cathedral ceiling, crawl space), the square footage, and your target R-value — so every quote reflects the same scope.

What to Ask Each Contractor

When you're calling Fredericton-area spray foam contractors, ask these specific questions before anyone comes to quote:

What type of foam do you use — open-cell or closed-cell — and what is the installed density and R-value per inch? For below-grade applications like basement walls and rim joists, you need closed-cell (2-pound density, R-6 to R-7 per inch). Open-cell foam absorbs moisture and should never be used below grade in NB's wet soils.

What thickness will you apply, and what total R-value will that achieve? For Fredericton basement walls, you're targeting R-17 to R-20 minimum under the NB Building Code. For rim joists, 2 inches of closed-cell (R-12 to R-14) is the standard recommendation.

What is your installer's training and certification? Spray foam requires proper mixing ratios between the A and B chemical components. Off-ratio application — one of the most common problems with inexperienced installers — causes foam that shrinks, smells, or never fully cures. Ask about training credentials and how long the installer has been applying foam.

Do you carry general liability insurance and WorkSafeNB coverage? This is non-negotiable. Spray foam involves chemicals that require proper handling, and you want to be protected if something goes wrong on your property.

Fredericton-Specific Considerations

Fredericton's river valley location means wider temperature swings than coastal NB — summer heat followed by winters that regularly hit -20°C or colder. This thermal stress makes proper spray foam application particularly important, because foam that was applied off-ratio or at the wrong ambient temperature can shrink away from framing members over time, creating air gaps that defeat the entire purpose of the installation.

Fredericton also has a reasonably competitive insulation market, which works in your favour when collecting quotes. You're not in a remote northern community where one or two contractors hold all the leverage — there are enough professionals operating in the capital region that competitive pricing is realistic.

Rebates and Timing

If you're planning a significant spray foam project, register for an EnerGuide evaluation through NB Power's Total Home Energy Savings Program before any work begins. The pre-retrofit evaluation is mandatory for rebate eligibility, and rebates can reach $5,000 provincially plus up to $5,000 through the Canada Greener Homes Grant. Getting your quotes lined up while waiting for the evaluation appointment is a smart use of that lead time.
