Frequently Asked Questions

R-value measures how well insulation resists heat flow. The higher the R-value, the better it slows heat moving in or out of your home. However, R-value is only part of the story. Real-world performance also depends on air sealing, proper installation, full coverage, and moisture control. If air moves through or around insulation, performance drops.

‍

If certain rooms feel too hot, too cold, or drafty, the cause is typically air leaks, missing or poorly installed insulation, or inadequate attic coverage. These issues force your HVAC system to work harder while still failing to deliver consistent comfort.

Common signs include high energy bills, uneven temperatures between rooms or floors, drafts, cold spots, or older insulation. We evaluate your home and provide a clear recommendation based on actual conditions, not guesswork.

Some insulation can settle, compress, or be affected by moisture. Properly installed fiberglass insulation does not settle and is designed to last the life of the home. Most issues come from poor installation, air movement, or moisture, not the material itself.

Air sealing closes gaps where air escapes or enters your home, such as around wiring, plumbing, framing, and attic penetrations. Without air sealing, fibrous insulation cannot perform properly. Therefore, controlling air leaks is critical.

Yes, we evaluate air leakage as part of every project and address key areas so your insulation performs as intended.

We install fiberglass batt insulation for walls, blown-in fiberglass for attics, and spray foam for targeted air sealing and high-performance areas. Each material is used where it performs best, not as a one-size-fits-all solution.

In many cases, yes. We evaluate your existing insulation to determine whether adding more will be effective or if removal and replacement is the better solution.

We inspect your current insulation and problem areas, provide a clear recommendation, and complete most smaller projects in one day. We maintain a clean job site and handle cleanup so the process is simple and efficient.
