"They did an amazing job. Showed up, did it and went above and beyond. I am a big fan and wouldn't bother to call another after this experience. They just plain rocked it! My attic had some insulation but not anywhere near enough. I was able to feel an amazing difference the first night. I would be willing to bet I recoup the full cost within one winter!"

Insulation questions, answered by experts

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Yes, insulated vinyl siding increases the R-value of your home. Depending on the quality and brand of the insulated vinyl, you can get an R-value that is up to 5 times greater than traditional vinyl siding. This can be fantastic for homeowners who are trying to lower their utility costs.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.
