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

The best type of insulation for your home will largely depend on your climate and the space in your home you are trying to insulate. Fiberglass, for instance, is excellent for cold climates as it has a high R-value and won’t settle much over time; spray foam works well for humid environments as it has excellent moisture-resistant properties.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

Insulating your basement walls offers numerous advantages that make the project well worth it. By adding insulation, you can reduce the chances of moisture damage to the house's structure and lower the odds of mold growth. You'll also add comfort to the space by reducing temperature swings and increasing your home's energy efficiency, potentially reducing your energy bills to earn your investment back.
