"They were very professional. Came out and gave a fair estimate. Arrived on time. Covered all surfaces not being sprayed. Sprayed generously. Nowhere was it sprayed with less than requested. Cleaned up especially well. Courteous, quick, accurate. Highly recommend them. I will use them again when I’m ready for phase three"

"All of the folks associated with this business were most informative and accommodating to questions I had before, during and after the installation. The installers are most professional; having highly experienced foam applicators and crews that are prompt to arrive and begin work. The installers ensure the customer is happy with the completed work before leaving your home/business, etc.. Finally, when the work is complete, the project site is cleaned, with all trash and debris collected and discarded by RBC. I had several bids by other company's but RBC topped them all! I highly recommend this company for your spray foam needs."

"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"

Insulation questions, answered by experts

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.

Without a doubt, insulating a garage door is a surefire way to make your home more energy efficient. Not only does insulating your garage door reduce your electric bills, but it also helps protect your valuables inside your garage, all while making for a quieter interior space. 

In regions that drop below 0 degrees Fahrenheit, your car's battery is at risk of malfunctioning in a garage that drops dangerously low. So, homeowners who reside in extremely cold climates can especially benefit from insulating their garages.
