Our Locations

In Chicago, there are a few areas of your home you need to pay special attention to when it comes to insulation. If you don’t have one of these areas insulated, it’s time to call ThermaSeal/Lakeside Insulation.

Attic Insulation

Your attic is one of the best places to insulate, as it’s one of the biggest culprits behind home energy loss. Warm air rises, and if your attic isn’t insulated or doesn’t have enough insulation, all that heat will escape right, leaving your home a lot less comfortable in the winter. During the summer, an attic that isn’t insulated is much hotter, which makes the rest of your home a lot more toasty as well.

Wall Insulation

Wall insulation provides decreased heating and cooling costs, a more comfortable home, and superior soundproofing. If you’ve ever been in a home without wall insulation, you may have noticed how loud traffic and other outside noises seem.

Basement Insulation

The lowest level of your home offers a lot of potential for energy savings, but not if it isn’t well-insulated. Even if your basement is unfinished and you don’t go down there often, don’t overlook it when it’s time to re-insulate. Basement insulation can save you up to $250 a year.

Crawl Space Insulation

For a space so small, your crawl space can significantly impact your energy costs. If you don’t insulate your crawl space, your home can be subjected to all kinds of moisture problems and skyrocketing energy bills. Whether your house has a ventilated or unventilated crawl space, our insulation contractors can help.

Insulation Materials We Offer

Fiberglass Insulation

Fiberglass is one of the most popular and cost-effective types of insulation material; it’s also one of the most effective products at stopping heat transfer and can be installed anywhere in your home, from basement ceilings to walls and around ductwork.

Cellulose Insulation

One of the most environmentally friendly insulation products, cellulose is made of mostly recycled materials. It’s similar to fiberglass insulation; it provides good sound control and can work well in many areas of your home.

Spray Foam Insulation

Spray foam insulation is ideal for small spaces, like the tiny cracks, gaps and crevices in your home where air leaks in and out. Stopping air infiltration is critical, and spray foam insulation is one of the best solutions.
