This is targeted work, not whole-house weatherization. We focus on the attic floor and the rim joist at the top of the foundation wall, the two places most older North Jersey homes lose the most heat, and we say so when a dedicated insulation contractor is the better call.
Signs your house is losing heat
- Upstairs rooms are cold in winter and hot in summer
- Ice dams form along the roof edge after snow
- The basement is cold and drafty along the top of the foundation wall
- Floors above the basement are cold underfoot
- You can see the attic floor joists through thin, settled insulation
- The heating system runs constantly and the house still feels drafty
Insulation services we offer
Attic floor insulation
Adding insulation over the attic floor to a reasonable depth, keeping soffit vents open so the roof can breathe.
Basement rim joist insulation
Sealing and insulating the band of framing on top of the foundation wall, usually bare in older homes and a major source of cold basement air.
Air sealing around penetrations
Closing the gaps where plumbing, flues and wiring pass through the attic floor and basement ceiling.
Pipe and duct insulation
Insulating heating pipes and ducts that run through unheated basements and attics so the heat reaches the rooms.
Coordination with heating work
When sizing a new furnace or boiler, we tell you whether insulating first would allow a smaller system.
How it works
- 1
Look at the attic and basement
We check insulation depth, air leaks, ventilation and moisture, often while already at the house for heating work.
- 2
Honest recommendation
If the work fits what we do, you get a by-the-job price. If the house needs more, we say so.
- 3
Installation
Most attic and rim joist jobs are done in a day, with the house kept clean.
- 4
Check the heating system
After insulating, the system runs less. We confirm the thermostat and zones are still balanced.
