Spray foam is one of the easiest trades to schedule — if your sub communicates. Here's what we tell every GC before we mobilize, so the spray day goes clean and nobody loses time.
Where Foam Fits in Your Sequence
We spray after rough-ins are complete and inspected — electrical, plumbing, HVAC — and before drywall. Windows and exterior doors should be in. If the roof isn't tight, tell us; wet substrates delay adhesion and we'd rather reschedule than spray a failure.
What We Need On Site
Power for our rig (or we bring generation), reasonable access for the trailer, and the areas to be sprayed cleared of material staging. We mask and protect windows, electrical boxes, and plates — that's our job, not your labourers'. The building needs to be vacated by other trades during application and for the re-entry period; we'll give you exact timing so you can sequence around it.
Temperature and Cure
Closed-cell foam applies year-round, but substrate temperature matters. In winter we may need temporary heat a day ahead — we'll flag it at quoting, not on spray day.
The Documentation You Should Demand
Any spray foam sub should hand you: current WSIB clearance, certificate of insurance, installer certification, product data sheets, and application records. We send the first two before we mobilize and the rest with the completed job. If a sub can't produce these, that's your inspection risk, not theirs.
Send us plans and we'll return a scope and quote within 72 hours — and if your schedule needs it in 24, call and we'll make it happen.
