Heat rises straight through an under-insulated attic. Updated attic insulation is the single most cost-effective upgrade for most Danville homes.

Loose-fill blown-in insulation covers every corner and odd-shaped space in your attic, filling gaps that batts simply cannot reach.
Learn More
Whole-home insulation assessment and upgrade for older Danville homes, covering attic, crawl space, and walls in a coordinated plan.
Learn More
Old, damaged, or pest-compromised insulation holds odors and traps moisture. We remove it cleanly before any new material goes in.

Cold floors in winter? An uninsulated crawl space lets frigid air rise straight into your living space. We seal and insulate it properly.
Learn More
Wall insulation reduces noise, eliminates drafts near outlets, and makes every room in your home more comfortable year-round.
Learn More
Insulation alone does not stop drafts. Air sealing closes the gaps around pipes, fixtures, and framing that let conditioned air escape.
Learn More
Basement rim joists are one of the most overlooked sources of heat loss in older homes. We insulate and seal them for immediate results.
Learn More
Closed-cell foam offers the highest R-value per inch available and also resists moisture - ideal for crawl spaces, basements, and rim joists.
Learn More
Open-cell foam is a cost-effective option for interior walls and attics, providing excellent soundproofing alongside solid thermal performance.
Learn More
Commercial buildings leak heat and cool air just like homes do. We insulate warehouses, offices, and retail spaces throughout the region.
Learn More
A crawl space vapor barrier blocks ground moisture from rising into your home, protecting floors, framing, and air quality from the ground up.
Learn More
Proper vapor barrier installation is the difference between a dry crawl space and a damp one. We size and seal it correctly the first time.
Learn More
Air leaks in your attic bypass even thick insulation. Attic air sealing closes those pathways before they waste your heating and cooling budget.
Learn More
Retrofit insulation adds thermal performance to finished walls and existing structures without a full tear-out or major renovation.

"The crew sealed our rim joists and added blown-in to the attic in one day. Our gas bill dropped noticeably the very next month. They showed us the depth markers before they left so we could verify the coverage ourselves."
- Greg M., Danville - Attic Insulation

- Linda T., Tilton - Crawl Space Insulation
"I called on a Tuesday and had an estimate by Thursday. They explained the difference between open and closed-cell foam without any sales pressure. The work was done the following week and turned out exactly as quoted."

Danville sits in Climate Zone 5, where winters regularly drop below 10 degrees and summers push into the 90s with high humidity. The wider your indoor-outdoor temperature gap, the harder insulation works. The U.S. Department of Energy recommends higher R-values for this zone than most of the country.
Old insulation that is compressed, water-damaged, or pest-compromised loses most of its effectiveness. Adding new material on top of damaged insulation traps moisture and odors. An in-person assessment is the only reliable way to know whether removal or a simple top-off is the right call.
Insulation slows heat movement. Air sealing stops the actual flow of air through gaps, cracks, and penetrations. Both are needed - insulation without air sealing leaves a large portion of the thermal benefit on the table, especially in older homes with irregular framing.
Ice dams form when heat escapes through the attic, warms the roof deck, and melts snow unevenly. That meltwater refreezes at the cold eave and builds up. Proper attic insulation combined with air sealing is the long-term fix - not just chipping ice or adding heat cables.
Closed-cell foam is denser, resists moisture, and delivers a higher R-value per inch - best for crawl spaces, rim joists, and exterior applications. Open-cell foam is softer, more affordable, and provides excellent soundproofing - well-suited for interior walls and attics above conditioned space.
Yes. The federal government currently offers a tax credit worth up to 30% of materials cost for qualifying insulation upgrades through 2032. Ameren Illinois also offers utility rebates. The Illinois Home Weatherization Assistance Program may cover costs for income-qualifying households. Ask your contractor for documentation before work begins.
Custom Danville Insulation is a licensed and insured insulation contractor company based in Danville, IL, serving east-central Illinois and western Indiana since 2018. We hold all required state contractor registrations to perform insulation work in Illinois, operating under the oversight of the Illinois Department of Financial and Professional Regulation.
Since 2018, we have completed insulation projects across 16 service types, working in homes ranging from century-old brick buildings near downtown Danville to postwar ranch houses throughout Vermilion County. Our team has hands-on experience with the older housing stock and climate demands specific to this region.
Homes built before 1980 were often built with insulation levels far below current recommendations. Many have settled, compressed, or degraded materials. An assessment is the right first step - not a full replacement, but an honest look at what is there.
Address moisture first. Installing insulation over a wet crawl space or a leaking basement traps moisture and creates conditions for mold. Fix the source of the water, confirm the space is dry, and then insulate. A good contractor will flag moisture issues during their assessment.
Yes. Many rebate and tax credit programs apply to individual improvements - like adding attic insulation or encapsulating a crawl space - not just comprehensive upgrades. Ask your contractor which programs your specific project qualifies for before work begins.
The ENERGY STAR Seal and Insulate program is a good independent resource for understanding how insulation and air sealing work together to reduce energy costs. When you are ready to get a local, in-person assessment, call us at (217) 444-0284.
Danville is a city of about 30,000 people in east-central Illinois, sitting on the Illinois-Indiana border along the North Fork of the Vermilion River. The city is home to a mix of older brick homes near the downtown historic core and postwar ranch houses throughout the surrounding neighborhoods. The median home in Danville was built well before 1960, which means most of the city is working with insulation - and in many cases, the lack of it - from an era when energy standards were a fraction of what they are today.
Local landmarks like the Vermilion County War Museum and Ellsworth Park are part of a community where people tend to stay put and take care of their properties for the long haul. Major employers like Carle Health and the local VA hospital anchor a stable, working-class population that is invested in keeping homes in good shape even on tighter budgets. Many of the homes near downtown Danville feature full brick exteriors, original plaster walls, and crawl spaces that have never been properly insulated or sealed.
Custom Danville Insulation has been working in Danville homes since 2018. We know the older construction here - the irregular framing, the vented crawl spaces, the rim joists that have never seen foam. If you own a home in this city, chances are there is a meaningful insulation improvement available that will make a real difference in your comfort and your energy bills. Call us and we will come take a look.
