"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

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.
