FAQ
Common Questions About Spray Foam Insulation
Q: How much can I actually save on energy bills?
Most customers see monthly savings of 25β40% on heating and cooling costs after spray foam installation. In Delaware and the Northeast, that typically means $150β300 less per month β depending on the size of your home and current insulation state.
Q: How long does spray foam insulation last?
Spray foam doesn’t sag, settle, or compress like fiberglass batts. When installed correctly, it lasts for decades β often the entire lifespan of the building. It’s a one-time install with permanent performance.
Q: Is spray foam safe for my family once it's installed?
Yes. Once fully cured β typically within 24 hours of installation β spray foam is completely non-toxic and odorless. It actively improves indoor air quality by sealing out allergens, dust, and pollutants.
Q: Can you insulate walls without removing my drywall?
In most cases, yes. We can drill small access holes and inject foam into existing wall cavities β no demolition required. This is a common retrofit solution for older homes and causes minimal disruption.
Q: Do I need to remove my old insulation first?
It depends on the condition. If your existing insulation is moldy, pest-damaged, or heavily compressed, we’ll recommend removal first to ensure the new installation performs as it should. We handle removal as part of our service.
Q: How long does installation take?
Most residential jobs are completed in a single day. Larger commercial projects may take longer. We’ll give you a clear timeline during your on-site estimate so you can plan accordingly.
Q: Do you offer any warranty on your work?
Yes. We stand behind every installation. If something isn’t performing as it should after we finish the job, we come back and make it right β no runaround, no fine print.
