Insulation Contractor services
-
Attic Insulation Installation
We install batt, blown-in, or loose-fill insulation in attics to bring them up to the R-value a Palatine winter calls for.
-
Spray Foam Insulation
We apply open-cell or closed-cell spray foam in attics, rim joists, and wall cavities where air sealing matters as much as R-value.
-
Insulation Removal
We remove old, wet, or rodent-damaged insulation and bag it out before any new material goes in.
-
Crawl Space Insulation
We insulate crawl space walls and rim joists and install vapor barriers over exposed dirt floors.
-
Wall Insulation Retrofit
We drill small access holes and dense-pack cellulose or fiberglass into existing wall cavities without opening up drywall.
-
Rim Joist and Band Joist Insulation
We seal and insulate the band joist area around the foundation, a common spot for drafts and heat loss.
-
Air Sealing
We seal gaps around can lights, plumbing stacks, attic hatches, and top plates before insulation goes in over them.
-
Insulation Inspection
We go into the attic or crawl space, measure what's there, and write down where it's thin, missing, or compressed.
Questions we get asked
How do I know if my attic needs more insulation?
If you can see the ceiling joists sticking up above the insulation, you're under the depth most Palatine homes need. We measure it during the inspection and tell you the current depth versus what we'd add.
Do you remove the old insulation first?
If it's wet, compressed, or has rodent damage, yes, we remove it before installing anything new. If it's dry and intact, we can often add new material on top of it.
How long does attic insulation take?
A standard attic job usually runs a few hours, depending on the size and whether old material needs removing first. We'll give you a time estimate once we've seen the space.
Will insulation help with ice dams on my roof?
Insulation and air sealing in the attic reduce the heat loss that melts snow unevenly and causes ice dams. It's usually the attic floor, not the roof itself, that needs attention.
Do you work on older homes in Palatine?
Yes. Older homes often have wall cavities with no insulation at all, which we can fill through small drilled access holes. We patch the holes after the insulation is blown in.
What's the difference between batt and blown-in insulation?
Batt insulation comes in pre-cut rolls and works well in open, regular-shaped joist bays. Blown-in insulation is loose material we blow in with a machine, which fills around wires, vents, and odd angles better.

Hours: Open Monday to Saturday, 8:00 AM to 6:00 PM.
Why pick us
- We show up at the time we schedule, not a window sometime that day.
- We test with equipment — blower doors and infrared cameras — instead of guessing from a walkthrough.
- We hand you a written report with the actual numbers, not a verbal summary.
- We explain what we found in plain language before we leave, not just in a document.
- We rank recommendations by what saves the most energy first, not by what's easiest to list.
Energy advisory service services
-
Home energy audit
We walk the property room by room, checking insulation, windows, doors, and mechanical systems for energy loss.
-
Blower door testing
We use a calibrated fan to pressurize the house and measure how much air is leaking out and where.
-
Thermal imaging inspection
We scan walls, ceilings, and floors with an infrared camera to find cold spots and missing insulation.
-
Utility bill analysis
We review past electric and gas bills to find usage patterns and spot where energy is being wasted.
-
Insulation assessment
We check attic, wall cavity, and basement insulation levels against what the house actually needs.
-
HVAC performance review
We evaluate how the heating and cooling system is running and whether it matches the size of the home.
-
Rebate and incentive guidance
We identify utility and state programs a homeowner may qualify for based on the audit findings.
-
Written energy report
We put every finding, measurement, and recommendation into a report you keep after the visit.
Questions we get asked
What actually happens during an energy audit?
We inspect the house inside and out, run a blower door test to measure air leakage, and check insulation and HVAC performance. Afterward, we go over what we found and put it in a written report.
How long does a visit take?
It depends on the size of the house and how many tests are needed. A typical single-family home audit involves a full walkthrough plus the blower door test.
Will you tell me how to fix the problems you find?
Yes. The report includes specific recommendations, ranked by what will make the biggest difference in energy use. We explain what each finding means before you decide what to do about it.
Do you install insulation or seal the leaks yourselves?
We're an advisory service — we assess and report. For installation work like adding insulation or sealing leaks, you'd hire a contractor who does that trade directly.
Can you help me find rebates for energy upgrades?
We can point you to utility and state programs that match the improvements your audit identifies. Whether you qualify depends on the program's own rules, which we don't control.
Is there a best time of year for an audit?
Audits can be done year-round, but testing for drafts and heat loss is often easier during colder months when the difference between inside and outside temperature is greater.
