In Plainfield, IL, where the weather swings from freezing winters to humid, sweltering summers, maintaining a consistent indoor temperature is a challenge for any property owner. South Chicago Insulation provides the expertise needed to secure your building envelope against these extremes. We target homeowners and business managers in Will County who are tired of escalating energy costs and drafty rooms. By utilizing advanced spray foam technology and building science principles, we create airtight seals that drastically reduce the workload on your HVAC systems. Whether you are constructing a new home near Route 59 or retrofitting a historic property downtown, our services deliver tangible improvements in comfort, air quality, and structural longevity.
An under-insulated building does more than just leak heat; it invites moisture, allergens, and noise into your living or working space. We go beyond simple batt installation by analyzing your property as a complete system. Our approach identifies thermal bridges and air leaks that traditional methods miss, ensuring a comprehensive upgrade to your property's efficiency. From preventing ice dams in the winter to blocking humidity in the summer, our tailored insulation strategies are designed to protect your investment and enhance your quality of life.





The Challenge: A two-story home in the Plainfield North subdivision was suffering from severe ice dams every winter. The homeowners were dealing with water damage on the second-floor ceilings and dangerously large icicles hanging from the gutters.
The Solution: Upon inspection, we found significant air leakage from the living space into the attic and insufficient fiberglass insulation. We performed a "remove and replace" operation. We extracted the old insulation, air-sealed all penetrations (light fixtures, plumbing stacks), and installed blown-in cellulose to R-60.
The Result: The air sealing stopped warm air from escaping into the attic, preventing the snow on the roof from melting and refreezing. The ice dams disappeared completely, the upstairs became comfortable again, and the client reported a 20% drop in heating costs.

For our climate, Closed Cell Spray Foam is often the most effective because it provides the highest R-value per inch and acts as a vapor barrier and air sealer, preventing heat loss common during freezing Illinois winters.
Common signs include fluctuating temperatures between rooms, cold walls to the touch, high energy bills, drafts near outlets, and ice dams forming on your roof gutters during the winter.
Yes. Open Cell Spray Foam, Cellulose, and Mineral Wool are excellent at sound dampening. They absorb sound waves, significantly reducing noise from traffic, neighbors, or wind.
Yes, when installed by certified professionals. We use high-quality materials and ensure proper ventilation during application and curing. Once cured, the foam is inert and safe for occupants.
Yes. If your existing insulation is damaged by water, mold, or pests, we can safely remove it using commercial vacuums and prepare the space for clean, new insulation.
Most residential retrofit projects, such as attic insulation or rim-joist spraying, can be completed in 1 to 2 days. Larger commercial projects will vary based on square footage.
R-Value measures a material's resistance to heat flow. The higher the R-Value, the greater the insulating power. In Plainfield, we aim for higher R-Values in attics and walls to combat the extreme temperature differences.
Absolutely. Encapsulating and insulating the crawlspace prevents the cold earth temperature from transferring to your floorboards, making your home feel much warmer underfoot.
Yes. We use "drill-and-fill" techniques, drilling small holes in the exterior or interior wall and injecting loose-fill insulation or injection foam, then patching the holes, leaving the wall intact.
Yes. We specialize in Spray Foam Roofing and Commercial Roof Coatings, which insulate the roof deck and provide a seamless, waterproof barrier for commercial buildings.
