we like to do estimates on Saturday but we will do are best to accommodate everyone's schedule

"We hired Angelo's spray foam and Russ a terrible job installing the spray foam you missed spots throughout the ceiling everywhere. We sent him pictures showing him spots he missed and spots that weren't as thick as what we paid for. He agreed that the quality of work was terrible and said he would come and fix it. After 12 weeks of not showing up and making up excuses of why he can't get here, he eventually told us he's not going to fix it. My wife and I filed a lawsuit against him. Too tired to redeem our money to pay another company to come and fix his work. Would not recommend this company"

Insulation questions, answered by experts

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.

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.

Don’t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.
