Jenks, OK: what's different here
Jenks sits in Tulsa County, about 11 miles and roughly 15 minutes from downtown Tulsa via US Route 75. Because the county is in Oklahoma Climate Zone 3, the residential energy code calls for wood-frame walls at R-15. Wall cavity foam injection is a common retrofit for existing homes, especially when siding is already coming off. A local pro can inspect your wall cavities and quote the job.
How is wall cavity foam injection installed in Jenks homes?
Many crews work from the exterior by removing a course of siding, drilling one hole per cavity, filling it, plugging the hole, and replacing the siding. This makes the method popular for existing homes. It is often recommended when siding is being replaced and the wall sheathing is exposed.
What R-value do walls need in Jenks, Oklahoma?
Jenks is in Tulsa County, which falls in Oklahoma Climate Zone 3. The residential energy code summary shows wood-frame walls at R-15 and ceilings at R-38 for Zone 3. Ask the contractor what R-value the foam will reach in your walls.
What paperwork should I get from the contractor?
The Oklahoma Residential Code requires the aged R-value per inch of spray polyurethane foam to be provided to the customer in writing at the time of foam application. Ask for that document before the crew starts. Also ask for proof of license and insurance.
What drives the cost of injection foam up or down?
A whole-house injection-foam project can range from about $3,000 to $20,000 depending on square footage, access, and foam type. Larger homes and hard-to-reach cavities cost more. Get an itemized quote so you know what you are paying for.
What to do next
- Count the exterior walls and note your siding type so the pro can estimate holes per cavity.
- Ask each contractor for the written aged R-value per inch the Oklahoma Residential Code requires at application.
- Ask for proof of license and insurance before signing, since rebate rules require a licensed professional installer.
- Request an itemized quote showing cost per square foot and total project price.
