Hi there from Dustin, owner of Insulation Nation! Here in So Cal, we join our Colorado office in providing personalized high touch experiences for our customers. I work with our customers directly every step of the way from evaluation, education and review of options, through the project and to inspection of the results. We've never seen less than a 5 star review. Small businesses live and die by reviews and we are ready to earn 5 stars on your project! Thank you! C-02 Insulation and Acoustic #: 1127373 EXP: 10/31/2026

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

Remodeling as it should be. Ted and Tony have one vision in mind; a customer focused, hands-on approach to home remodeling. From the early stages of a concept to the final details of construction, our goal is to create a positive experience. We understand that no two customers are exactly alike, so we take the time to create solutions that appeal to your personal tastes and fit your budget. We offer two basic approaches to bathroom remodeling – Semi Custom and Client Inspired designs. Check out our website for further information.

"Look no further than Verity Build if you want a beautiful kitchen remodel. Verity just completed our kitchen remodel and we couldn’t be more pleased working with this company. The owners Ted & Tony are exceptional to work with. Ted designed our kitchen and came up with many wonderful ways to effectively use our space. He is patient and listens carefully to what you want, making excellent suggestions along the way. He accompanied us while we shopped to choose the appliances needed as well as the tile, backsplash & countertops. His 3D renderings showed us exactly what the new kitchen would look like, being able to move & change cabinets to look and work best. When the project started, Tony was onsite to make sure it happened according to the plan. Tony closely monitored the crew and kept in great communication with us throughout the process. The Verity crew is topnotch and does high quality work while always being professional, courteous and friendly. The worksite was kept organized and cleaned up each day for the next phase. The project was completed on time and Ted, Tony, and office manager Jennifer were readily available to answer questions and follow-up on any detail that needed attention. We look forward to working with the Verity crew again when we are ready to move forward on our bathroom remodels."

Tal helped us select the new stunning marble slab for the new island that he implemented in the design and the gorgeous chandelier above it because the island that he designed for us included table as well. Tal Mechaly was amazing at selecting all the paint colors combinations and with his design… he was able to pull it all together as one piece of art kitchen. Tal Mechaly was very easygoing person to work with, with excellent creativity skills and his thinking outside of the box ability was beyond believes."

Insulation questions, answered by experts

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.

There are two places where you should not place foam insulation: around electrical boxes or near lightboxes. The foam insulation could get inside the electrical boxes and damage the wiring. Spraying foam too close to a lightbox creates a potential fire hazard; it could also cause damage to the light.

The type of insulation you need in your home depends on your location, the installation site, and your region’s climate. According to Energy Star, insulation in homes in the Southern United States should have an R-value of between R30 and R60 in attics and R13 to R25 in the floors and walls; homes in moderate climates require R values of R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require an R value of R49 to R60 in attics and R25 to R30 in floors and walls.

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.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.
