"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."

"Antonios did exactly what he said he would do. I had to work so I left a portion of my home open to them so they could be comfortable while they were there. I felt like I could trust them, so I did. My first night with it, I put my AC down to 72* instead of 68*. I woke up freezing instead of hot. This was and will be my best purchase I’ve done to increase the value of my home. Thank you Antonios for your help."

Insulation questions, answered by experts

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.
