Cold floors in winter. Hot rooms in summer. A power bill that keeps climbing. The fix isn't always inside your house — half the time it's the saggy, wet, rodent-damaged insulation hanging in your crawl space.
If any of these apply, your crawl space is costing you 10-20% of your monthly energy bill — and possibly affecting your indoor air quality.
For most homeowners, new insulation pays for itself within 4-7 years through energy savings alone.
Depends on whether your crawl space is encapsulated. In a sealed (encapsulated) crawl space, insulation goes on the foundation walls. In a vented crawl space, insulation goes between the floor joists.
Properly installed and protected from moisture: 25-50+ years.
We don't recommend it. If the old insulation is wet, moldy, or contaminated, layering new on top traps the contamination against your sub-floor.
Most homes see 10-20% reduction in heating and cooling costs. Older homes with no working insulation can see more.
Yes — if the cold floors are caused by missing or failing insulation. We'll diagnose during inspection so you don't pay for the wrong fix.
Wet insulation = zero insulation. Fiberglass batts absorb moisture and fall down. Once they're wet, they actually make things worse by holding moisture against your floor joists. If your insulation is sagging, dark, or crumbly — it needs to come out. Fresh insulation can drop your energy bills by 15–20%, and most homeowners feel the difference the first winter. That's real money back in your pocket! 💰
