"All went well I had an asphalt roof replacement done. The job went very well smoothly they showed on time for the job with a dumpster and enough crew to complete the job in an impressive one day and a cleanup. My contact was Matthew Gritzke and he was well versed in what needed to get done. And had a dumpster and all supplies needed to complete it"

Insulation questions, answered by experts

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.

Winterization includes blowing out water, shutting off the system, and insulating exposed components to prevent freezing.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.
