"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 is great to work with. I hired him originally to blow insulation in my attic then he brought to my attention that the house I just bought has a mouse problem. Lucky for me Aaron is in the process of fixing that issue for me as well. He s been great to deal with and is a very professional and kind person."

Insulation questions, answered by experts

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

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.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

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, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.
