What it is, in plain English
If your existing insulation is clean, dry, and just shallow, you don't need to start over. A top-off adds new blown-in directly on top of what's there, bringing your attic up to current R-49+ standards at a fraction of the cost of a full removal-and-replace.
What's included
- Inspection-first to confirm existing insulation is healthy
- Compatible blown-in added to reach your target R-value
- Air sealing performed first if leaks are present
- Baffles added or repaired to keep soffits clear
- Same depth-ruler verification as a full install
Frequently asked
When is a top-off NOT a good idea?
If your existing insulation is wet, moldy, rodent-contaminated, or made of vermiculite (potential asbestos), it needs to come out first. We'll tell you straight during the free inspection.
Can I top off myself with bags from a hardware store?
You can, but you'll likely get inconsistent depth, miss the air-sealing step, and bury problems like ductwork or junction boxes that need to stay accessible. Most DIY top-offs underperform their paid R-value by 20–30%.
