Older homes leak most of their comfort through empty or half-filled walls. Dense-packing fixes them without tearing the house apart.
Empty walls in an older home are a radiator to the outdoors - and even homes with sagging old batts have gaps working against them. Dense-packed cellulose fills the entire cavity at a density that resists both settling and airflow. The change is felt the first cold week: walls warm to the touch, drafts gone, furnace cycling less.
It's the single best comfort upgrade for pre-1980 houses, and it's done from little holes, not gut renovation.
No - we work through small, plugged and patched openings. Vinyl and lap siding lift and reinstall cleanly; interior work gets patched paint-ready.
Density is felt at the hose, and we verify with thermal imaging - voids show cold, and we go back in until they don't.
Active knob-and-tube must be dealt with before insulating around it - we'll check and tell you straight, with an electrician referral if needed.
