"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 level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.
