Madison & Dane County · Insulation and air sealing
Stop heating the attic. Start heating the house.
Isthmus seals the leaks and tops up attics, walls and rim joists so your furnace runs less through a Wisconsin winter. We start with a blower-door test and file every rebate we can find for you. This is a demo, not a real insulation company.
Madison is in climate zone 6. The DOE recommends R-49 to R-60 in the attic.
Seal first, then insulate
Warm air escapes through gaps around light fixtures, plumbing stacks and top plates. We foam and caulk those first, then blow insulation to an even depth with marked depth rulers you can check yourself.
Services
Cellulose topped up to R-60 with air sealing and baffles.
From $1.85 / sq ftTop plates, chases, can lights and the attic hatch.
From $850Cellulose blown into empty walls of older homes from outside.
From $2.40 / sq ftClosed-cell foam in the basement band joist, a top source of drafts.
From $1,100Rigid foam on walls, sealed vapor barrier on the floor.
From $2,600Vacuum removal of rodent-damaged or wet insulation.
From $1.50 / sq ftRebate checker
Wisconsin utility and state energy programs pay part of the cost of air sealing and insulation, and income-qualified households can get most of the project covered. Answer four questions for a sample estimate; we confirm eligibility at your audit and file the paperwork.
Sample amounts for a website demo.
Energy audit
We depressurize the house and measure air leakage in CFM50.
Infrared images show cold walls, gaps and missing insulation.
Combustion and CO testing on the furnace and water heater.
A prioritized plan with prices and the rebates each step qualifies for.
Audit fee: $149, credited in full when you book any insulation project within 90 days.

Reviews
“The thermal camera showed our upstairs bathroom wall had no insulation at all. It's not freezing anymore.”
— Hannah, Middleton“They filed the rebate and it came off the invoice. Our January gas bill dropped by about a third.”
— Marcus, Fitchburg“Rim joist foam fixed the cold basement floor we'd complained about for ten years.”
— Jen, Sun PrairieFAQ
Usually not. We blow new cellulose right over clean existing insulation. We remove it only if it is wet, moldy or full of rodent droppings.
Grey-brown, pebbly vermiculite can contain asbestos. We arrange a lab test before anyone disturbs it.
We test after sealing. If the house gets tight enough to need fresh air, we'll recommend a bath fan timer or an ERV.
