"Holly from Koala was amazing from the start to the end. I originally I had them come over to give me a quote for spay insulation. Holly went over my options that were best for my house. After the work was completed my house has stayed cool which is amazing in this hot hot tecas summer. They also gave a Veterans discount!"

"After checking out several insulation companies, I chose to hire Elite Insulation Specialist. I am very pleased with my decision. Their price was by far the best and I felt like they were very honest and straight forward. The guys arrived early to the appointment and we’re done in less than an hour. They were friendly and professional throughout the entire process. I will be recommending Elite I dilation to friends and family."

"Tech who showed up to do inspection was thorough. Climbed into small attic, took pictures and explained what their findings were. Other inspections (I had 2 more) just popped their heads into the entrance and too my word for what may need to be done. Scheduling with Attic Construction was simple. They showed up on time (early). They let me peak up their as they cleaned up old insulation and remove rodent droppings (biggest concern). They finished within the day as promised and cleaned up after themselves thoroughly. Our home was well protected from dings/damages as they wrapped corners of walls, stairs etc. We have noticed improvement from having only 3.5 inches of insulation to now nearly 14-15 inches. They recommended a "combo" of batt insulation (Around the entrance) and blown in for the rest of the area. This allows you to pop in there with out blown in insulation falling all over the place. They also recommended and performed rodent proofing/sealing. We were sent photos of both before and after their work. I would highly recommend this company."

"They sent out the owner who did a complementary energy audit - we followed his advice and blew insulation in our attic and wrapped the ductwork. Our energy bills have been reduced dramatically!"

"Attic Fanatics did an awesome job from start to finish. They removed our old insulation and installed new insulation, and they were the only company that explained how important air sealing is. They also recommended a solar attic fan to help with summer heat and attic humidity, which we ended up going with and are glad we did. Everyone we worked with was great, from the sales rep to the installers, and they even had a project manager on site making sure everything went smoothly and that we were happy the whole time. Super smooth process and a 10/10 experience. I’d definitely recommend Attic Fanatics to friends and family."

Insulation questions, answered by experts

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Yes, many services include adding insulation for energy efficiency. Confirm with your contractor.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.
