"Matias and his crew were excellent! They blew new insulation in my attic for me, and I am thrilled with the result. They ran into an issue accessing part of my attic, but thanks to their creative problem-solving, they worked around it and were able to get insulation throughout the whole attic. They truly went above and beyond, and I would recommend them to anyone who needs insulation work done."

Insulation questions, answered by experts

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

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.

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.

If you're replacing insulation, it's a good idea to remove the old insulation before adding new. This is especially true if the existing insulation has suffered from water damage or been exposed to pests. You also need to remove old insulation if you'll be installing a new and different type of insulation, such as trading roll or batt insulation for spray foam.
