"Unique product making a dent in insulation market. Milex is shaped like packing peanuts so will not settle and compress like blown in insulation. Price was below some competitors we priced. Plus Texas owned company. Definitely happy with how much warmer our home feels."

"The team at NxT Level Insulation did an exceptional job with our attic insulation. Dillon was incredibly helpful in explaining the process and the crew he led was efficient and professional. We're noticing the difference already - the temperature is more consistent throughout the house, and our HVAC is running much better."

"The representative was very knowledgable about the scope of work. I called him for the replacement of the attic insulation due for rats. I had pest control guy tell me my attic insulation had to be replaced. The rep, Guy, told me that wasn't what I needed. He told me that replacement the attic insulation would not solve my rats. He gave me names of good pest controls. Guy said to contact them before spending thousands of dollars for rats in my attic. Thank you Guy."

"Did a great job. Kept me updated on anything they would find while removing the old insulation and replacing with new. Showed up on time and the crew was polite and hard workers. Recommended them to my neighbor and they will have their Attic cleaned and replace their insulation also. Highly recommended."

Insulation questions, answered by experts

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.
