Bartonville sits right on the south edge of Peoria along IL-Route 116, and I run spray foam jobs there more often than most homeowners might expect. Being just minutes from our main service area means we can schedule Bartonville jobs quickly and without the drive premium that contractors charge for outlying towns. If you are in Bartonville and dealing with high energy bills, cold floors, or a crawl space problem, call 309-491-4457 and we will come take a look.
The village of Bartonville has a housing stock that mirrors what I see across Peoria County’s older neighborhoods — bungalows and two-stories built in the decades after World War II, solid construction but with little to no meaningful air sealing. The heating systems in these homes work harder than they should because the building envelope was never designed to hold conditioned air in. Spray foam addresses both problems at once: it insulates and air-seals in the same application, which is why adding more batt insulation almost never solves the problem homeowners are trying to fix.
What Drives Energy Loss in Bartonville Homes
Bartonville homes have the same structural vulnerabilities common to older Peoria County housing. The rim joist — the band of framing that runs the full perimeter of the foundation at floor level — is almost always uninsulated or has deteriorated fiberglass stuffed in without any air sealing. Cold air infiltrates at this point year-round and is responsible for a significant portion of the heat loss in older homes. Two inches of closed-cell spray foam along the full rim joist perimeter seals every crack and brings that section to R-12, often producing a noticeable improvement in floor temperature within the first cold night after the job.
Crawl spaces are the second major source of energy loss I see in Bartonville. Older vented crawl spaces pull humid summer air into the floor system, allow cold air to back-draft up through the floor in winter, and create the conditions that lead to mold and rot in floor framing over time. Converting a vented crawl space to a sealed encapsulation with spray foam on the walls is the highest-return project available for most older Bartonville homes.
Spray Foam Applications That Work in Bartonville
- Rim joist insulation. The highest-return application in most Bartonville homes. Closed-cell foam seals and insulates the full perimeter in two to three hours. Most homeowners notice the difference immediately.
- Crawl space encapsulation. We seal the vents, spray foam the crawl space walls, and convert an open liability into a sealed zone. Eliminates cold floor issues and removes the primary mechanism driving moisture problems in the floor framing.
- Attic air sealing and insulation. We move existing insulation, seal every penetration through the ceiling plane with spray foam, then reinstall or supplement. This consistently outperforms simply adding more insulation depth without addressing the air pathways first.
- Basement wall insulation. Closed-cell foam on interior concrete or block walls controls moisture vapor, stops cold conduction inward, and turns an uncomfortable basement into usable conditioned space.

| Attic air sealing | Open or closed-cell | $900 – $2,200 |
| Full attic spray foam | Open-cell, 6" | $3,000 – $5,800 |
| Basement walls | Closed-cell, 2" | $2,200 – $4,800 |
All prices are all-in installed — materials, labor, equipment, and cleanup. The number on the written estimate is what you pay.
Closed-Cell vs. Open-Cell Spray Foam for Bartonville Homes
Closed-cell spray foam delivers R-6 to R-7 per inch and acts as a Class II vapor retarder. It is the right product for any moisture-sensitive or below-grade application: rim joists, crawl space walls, and basement walls. Open-cell foam delivers about R-3.7 per inch at a lower cost and is vapor-permeable, making it the right choice for full attic fills and interior wall cavities. Most Bartonville homes use both products in different locations based on the specific application. For a full breakdown, see our open-cell vs. closed-cell spray foam guide.
