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."

Attic insulation installations FAQs

The best type of insulation for your attic depends on your climate, budget, and whether your attic is new construction or an existing space. For example, structural insulated panels are ideal for new builds and offer excellent energy efficiency. In warmer climates, reflective insulation can reduce cooling costs, while blown-in, loose-fill, and spray foam insulation are great options for filling irregular spaces in existing attics. It's important to consult with a local attic insulation prol to determine which insulation type best suits your specific needs.

Absolutely. Insulating your attic reduces heat loss in winter and heat gain in summer, leading to lower energy bills and a more comfortable home year-round. It can also increase your home's resale value, as energy efficiency is a desirable feature for buyers. Investing in attic insulation is a smart way to improve your home's efficiency and comfort.

Yes, you can usually add more insulation to your attic over the existing material to improve its effectiveness. If your current insulation is dry and in good condition, adding layers can enhance thermal resistance. However, if the existing insulation is wet, moldy, or damaged, it should be removed and replaced to prevent health issues and ensure proper insulation performance. It's important to have a professional assess your attic insulation to determine the best course of action.

Insulating an attic can take anywhere from five hours to two days. The project length depends on the insulation material you choose, for example, spray foam insulation takes about one to two days to install. Another factor is if you need to remove old insulation before adding in new insulation.

Yes, you can over-insulate an attic, although this isn’t as common as under-insulating your home. Too much insulation can lead to inadequate ventilation, blocked vents, and poor air circulation, resulting in mold or trapping in heat. To avoid these issues, contact your local insulation professional about finding the right R-value for your home.

You typically do not need to hire an electrician for standard attic insulation projects if you're simply adding or replacing insulation. However, if your insulation work involves moving electrical wiring, installing new fixtures, or addressing any electrical issues, you will need to hire a licensed electrician. It's important to ensure that all wiring is properly handled to prevent safety hazards and comply with building codes. If you suspect any problems with your attic's electrical system, consult a local electrician before proceeding with insulation.
