Basement and Crawlspace Insulation in Decatur, Illinois

You want your home to be at a comfortable temperature all year round. At the same time, heating and cooling costs can skyrocket at peak times, and you struggle to keep the house warm or cool enough. What’s the problem? It could be your basement. If your basement hasn’t been insulated properly, your whole home will feel the effects. What’s the solution? The basement and crawl space insulation experts at Assured Insulation in Decatur, Il can assess your insulation needs and properly insulate your basement for maximum comfort and reduced energy costs.

Finished Basements

When we talk about finished basements, we refer to the types that are heated by the furnace and cooled by an air conditioning unit. A finished basement will have a thermal barrier extending from the living space. If air gets into your basement, it leaks into the living space, making the living space and the basement too warm or too cold, depending on the season. Your heating and cooling systems work hard to compensate, raising your energy costs. The proper amount of quality insulation prevents the air from leaking into living spaces, making your home temperature more comfortable and saving you money.

Unfinished Basements

An unfinished basement often lacks wall and basement ceiling insulation, creating even more opportunity for warm air to leak inside during a hot summer and cold air to make its way inside during the winter months. Assured Insulation can help residents in Decatur and surrounding areas by adding insulation to both the walls and ceiling. If you have insulation and don’t have to heat or cool this area, you save money as well.


The open space underneath your home is called a crawlspace. Sometimes, it’s just an empty space while in other situations it provides access to home systems. In either case, it’s outside of the home’s thermal boundary and not heated or cooled, so if air gets from the crawl space gets into your home, your air and heating systems will battle to moderate the temperature. Wasted energy equals higher costs.

A sufficient amount of insulation halts energy waste and reduces the potential for excessive moisture and mold growth. Crawlspace insulation helps prevent other allergens and irritants that could come into your home through the ventilation system.

Crawlspaces can be ventilated or unventilated. In a ventilated space, heat water lines should be wrapped in insulation to prevent wintertime freezing. A direct-to-floor application using spray foam can work well in a ventilated crawlspace, blocking air flow into the home. Trust the experts at Assured Insulation Decatur to provide a solution for you.
