Application of spray polyurethane foam to caulk complex structural entry points and simultaneously isolate hard-to-reach areas.
The principle: Sprayed urethane adheres without mechanical fastening, conforms to irregular shapes, and offers airtightness, R-6 thermal insulation per inch, and an impassable physical barrier for rodents. Ideal for stone foundations, edge joists, skylights.
Nova Extermination provides this service on the South Shore with RBQ 5734 75930 01 license and a warranty adapted to the case. All our work complies with CNESST standards for the protection of occupants and technicians.

Preparation and masking, application of 2 to 3 inch thick closed-cell foam, trimming of excess, adhesion checking, installation certification
Average duration: half a day to 1 day depending on the surface area.
Underwriting and Inspection
Here are the service variants we offer for this need:
- Rim joists or foundation perimeter
- Complete crawl space
- Combination of waterproofing + R-30 insulation (cathedral roof)
What influences the quote
- Surface or volume to be treated
- Extent of the infestation or situation
- Accessibility of the areas concerned
- Response time requested (planned or emergency)
- Scope of the desired warranty
- Documentation required for insurer, notary or audit
The inspection is non-binding. We evaluate on site (or by phone as the case may be) and give you a written estimate adapted to your building before any work begins. No unpleasant surprises at the end.
Warranty and certifications
25-year warranty on thermal performance, rodent tightness warranty evaluated on a case-by-case basis.
Why entrust this service to a pest control specialist rather than a general contractor:
- Specialization: we know where to look, what to seal and what doesn’t need to be sealed (saving on the quote)
- Coordination: if an infestation is still active, our technicians intervene before the work, without calling on a second service provider
- Double guarantee: on the work AND on the non-recurrence of the pest
Services that are often combined with it
Questions
Is urethane safe for occupants?
Yes, once cured (24 to 48 hours). During application, the area is evacuated.
How long is the warranty?
25 years on thermal performance according to the manufacturer. 5 years written by Nova on rodent tightness.
Can you combine urethane and cellulose?
Yes, it is even recommended to optimize the cost/performance ratio: urethane on technical areas (edge, joists, junctions), cellulose on large surfaces.
Is the quote non-binding?
Yes, the preliminary assessment and written quote are non-binding.
Coverage by home insurance?
Depending on the initial cause, yes in many cases. We provide the necessary documentation for the claim.

Frequently Asked Questions: Urethane Insulation
What is spray urethane insulation?
Spray urethane insulation involves spraying polyurethane foam that expands and hardens to form an insulating, airtight barrier. It is often installed after decontamination to replenish insulation removed from an attic or crawl space. Our technicians apply it in buildings on the South Shore and Montérégie.
Why choose urethane after decontamination?
Urethane provides excellent insulating value and seals cracks and small openings through which pests would infiltrate. By plugging these gaps, it contributes to the exclusion of rodents and insects while improving energy efficiency. It is a popular choice for attics and crawl spaces in Longueuil or Chambly.
Does urethane help prevent pests from returning?
By sealing gaps, urethane reduces secondary access routes, but it does not replace the closure of primary entry points. It is therefore part of a global approach combining exclusion, sealing and insulation. Treated in this way, the building becomes less hospitable to rodents in Saint-Bruno or Beloeil.
How is the application of urethane foam performed?
After sanitizing and preparing the surface, our technicians spray the foam using specialized equipment, respecting the drying times and the required ventilation. The product used is approved and applied according to the safety standards in force. The thickness is adjusted according to the insulating value targeted.
Do you offer a warranty on urethane insulation?
We aim for a durable and compliant installation, evaluated according to each project, without promising an absolute guarantee covering all building conditions. A degraded, damp or dilapidated support can influence the result and is the responsibility of the owner. Our technicians will advise you on the right preparation.
What is the cost of urethane insulation?
The price is established on the basis of an evaluation, depending on the surface to be covered, the targeted thickness and the access to the premises. An inspection in Sainte-Julie or elsewhere on the South Shore allows you to estimate the cost of the work. It is a paid service carried out by RBQ certified technicians.
