Questions homeowners ask us all the time

We’ve helped hundreds of families across Illinois and Indiana upgrade their comfort. Here’s what they usually want to know before getting started.

1. What is a home performance contractor, and how is it different from a regular insulation company?

A home performance contractor takes a whole-house approach. Instead of treating symptoms, like a cold room or high bills, we diagnose and fix root issues using building science. That means better results across comfort, energy use, and indoor air quality.

2. Do I need an energy audit before starting insulation work?

Not always, but it helps. An energy audit gives us precise data about where your home is losing energy. With tools like blower door tests and thermal imaging, we can target the upgrades that’ll make the biggest difference.

3. Can air sealing and insulation really lower my energy bills?

Absolutely. Many of our customers see 15–30% savings after upgrades. Sealing leaks and adding proper insulation reduces strain on your HVAC system, keeping temperatures stable without overworking your equipment.

4. Is spray foam better than blown-in insulation?

It depends on your home. Spray foam offers higher R-values and acts as both insulation and air barrier, but it’s more expensive. Blown-in insulation is more cost-effective for large areas like attics. We’ll recommend what fits your space and budget.

5. Will I qualify for any energy rebates or tax credits?

Most likely, yes. Many Illinois and Indiana homeowners can get instant rebates and up to $1,200 in federal tax credits for insulation, air sealing, and energy audits. We help you apply, no paperwork headaches.

6. How long does installation usually take?

Most insulation or encapsulation jobs take 1 to 2 days. Larger projects, like whole-home upgrades, may take a bit longer. We’ll always give you a clear timeline upfront.

7. Are your technicians certified and insured?

Yes. Every project is handled by certified professionals trained in BPI (Building Performance Institute) standards. We’re fully licensed, insured, and committed to quality work that meets strict performance and safety benchmarks.
