"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"Can't say enough good things about this company, an overall pleasure to deal with. The owner responded fully to all my questions and the crew that came to do the work was excellent. The owner stopped by the second and final day to see how things had gone on the first and assure me that he and the crew were only a phone call away if I had any questions or issues. I have another insulation project and I intend to use Koala Insulation and I expect the same results. Thanks for the great job!"

Drywall Insulation FAQs, answered by experts

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

Eco-friendly options reduce environmental impact and often improve indoor air quality.

The best way to make long, straight cuts is to use a utility knife and a T-square to score the sheet, snap along the score, and then finish the cut by cutting through the paper on the opposite side with the utility knife. If you’re making small cuts, curved cuts, or cutouts for electrical boxes or light fixtures, you can use a manual jab saw to keep costs down, but an electric spiral saw or oscillating multi-tool will get the cleanest, fastest cuts possible.

Most load-bearing walls are exterior, though they can also be interior.
