"Aaron and his team got the attic insulation done on time and exceeded my expectations. He was very polite and professional in all aspects concerning this job. He did everything I asked and even gave me pictures of before and after ... I would recommend Tri-Star Wildlife to anyone ... you won't regret it. He saved me money and did more than what the other company's were asking. Mark Raith"

"Was most impressed rep. Enjoyed our conversation. He was clear in describing processes; forthcoming on costs, educational on differences in products. Under other circumstances, ie, remaining in this house, would undertake insulation."

Insulation questions, answered by experts

Although spray foam insulation typically has a higher price point than traditional insulation, the benefits often justify the investment. It offers superior sealing properties, which can lead to significant energy bill savings. Spray foam also provides excellent moisture resistance and soundproofing. Other advantages include improved indoor air quality by minimizing allergens, a long lifespan of 80 to 100 years, added structural strength to the home, and a straightforward installation process.

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.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

Yes, you should add an insulative cover to outdoor water spigots in the winter for better protection against freezing. Make sure to use waterproof insulating material—something like a towel or old shirt can actually make the faucet more prone to freezing when the material soaks up rain or snow.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills.
