**Common Spray Foam Mistake #2: Gaps Behind the Foam**
Spray foam may look good from the outside⦠but small gaps behind the foam can create big problems.
When spray foam pulls away from the rafters or does not fully bond to the wood, it can leave hidden openings that allow hot, humid Louisiana air to sneak in behind the insulation.
That can lead to:
β Air leaks
β Moisture intrusion
β Mold growth
β Pest entry
β Higher energy bills
β Poor long-term performance
At Sunlight Contractors, we donβt believe in βspray and walk away.β
We inspect.
We test.
We verify.
We look for the details most contractors miss.
Because a proper spray foam job is not just about covering the surface β it is about creating a tighter, healthier, longer-lasting home.
**Small gaps can lead to big problems.**
