Attic, crawl space, and whole-home spray foam for Del City's postwar homes — quoted free, per job.
Postwar ranch homes east of OKC — big comfort gains on a working budget.
Del City sits just east of Oklahoma City, built up in the postwar decades for the same Tinker Air Force Base workforce that filled Midwest City next door. Its homes are modest, solid, and insulated to 1950s standards. Foam work here is about value: seal the attic, cut the summer bill, and make a smaller home comfortable without a renovation-sized budget.
Del City was founded in 1948 and filled in through the 1950s, 60s, and 70s with compact single-story ranch and brick homes — many of them around 1,000 to 1,400 square feet, noticeably smaller than the metro's newer suburbs — on a mix of slab and pier-and-beam foundations. They were built fast and affordably for military families and base workers, in an era when energy was cheap and nobody insulated to modern standards. Attics typically got a few inches of blown-in or a single layer of batts, and many wall cavities were left empty.
Five to seven decades of Oklahoma summers have settled and thinned whatever was up there, so the typical Del City house today leaks heat at the top and runs its air conditioner long into the evening. Demand here is remodel and retrofit demand: first-time buyers fixing up a starter home, landlords cutting the utility complaints that come with an uncomfortable rental, and long-time owners who want the bill down. Because the homes are smaller and the budgets are real, the work gets sequenced by payoff — attic first, crawl space second, walls when they're open anyway.
Attics are the most common job by far: foam seals the attic floor or roofline, keeps conditioned air inside, and takes pressure off your HVAC through Oklahoma's 100-degree stretches. See how it works on our attic insulation page. Del City's pier-and-beam homes add a second regular, the crawl space, where closed-cell foam ends cold floors and damp under-floor air. Metal buildings and garages round out the list — closed-cell foam bonds to the metal, stops condensation, and insulates in the same pass; details are on the metal building insulation page.
| Job | Typical Del City property | Usual approach |
|---|---|---|
| Attic retrofit | 1950s–70s ranches with a few settled inches of original insulation | Old insulation removed where needed, then open-cell foam on the attic floor to seal and insulate in one pass |
| Crawl space sealing | Pier-and-beam homes with cold floors and musty smells | Closed-cell foam on crawl space walls and rim joists to close off damp outside air |
| Remodel wall package | Homes mid-renovation with walls already opened | Foam sprayed into the open cavities before drywall goes back — the one chance to fix empty walls |
| Garage & shop | Detached garages and small backyard shops | Closed-cell foam on walls and roof to insulate and stop condensation dripping on tools and equipment |

Open-cell is the budget-friendly pick for attic floors and interior walls; closed-cell brings higher R-value per inch, moisture resistance, and rigidity for crawl spaces and metal. In Del City the split usually lands as open-cell in the attic and closed-cell underneath the house. The full plain-English comparison is on our open-cell vs. closed-cell page, and the free quote settles which fits your building.
Attic jobs commonly run $2,500–$6,000 depending on size and foam type; whole-home and metal-building jobs run higher. As a planning rule, spray foam in the OKC metro runs about $1.50–$4.50 per square foot installed — open-cell at the lower end, closed-cell at the higher end. One cost note specific to Del City: the smaller footprints mean smaller spray areas, so many attic jobs here land toward the lower half of that range — confirmed at the free inspection, never promised in advance. Older attics often need the failed original insulation removed first, and that removal is included in the quote when needed. For the full breakdown, see spray foam insulation cost in Oklahoma City.
You don't have to foam a whole house at once, and in Del City most people don't. The attic is where a postwar home loses the most conditioned air, so it comes first — and it's the job open-cell foam was made for. A pier-and-beam home's crawl space is the second half of the comfort equation: closed-cell foam on the crawl space walls and rim joists stops the damp air that sits under the floors, and our crawl space insulation in Oklahoma City page walks through how it works. Walls come last, during remodels. For the full metro picture, see spray foam insulation in Oklahoma City.

Typical attic jobs in the OKC metro run about $2,500–$6,000 depending on attic size and foam type, and Del City's smaller postwar homes often land toward the lower half of that range simply because there's less attic to spray. By the square foot, open-cell foam generally runs about $1.50–$2.50 and closed-cell about $2.50–$4.50 installed. Every quote is free and per job — no price is promised on this page.
Yes — it's the norm, not a defect. Most Del City homes went up in the 1950s through 1970s, when energy was cheap and insulation standards were minimal. A few inches of blown-in or a single layer of batts was a typical attic for the era, and fifty-plus Oklahoma summers of settling have thinned it further. Modern guidance for our climate zone targets about R-38 in the attic, which is roughly ten inches of open-cell foam — several times what most of these houses started with.
The attic, almost every time. Heat and air leakage concentrate at the top of the house, so sealing and foaming the attic delivers the biggest comfort and bill improvement per dollar — and open-cell foam keeps that job at the lower end of the cost range. A crawl space comes second if your home has one. Walls are last, and only worth doing when a remodel has them open anyway.
Usually, yes. In Del City's older homes the original batts or blown-in are typically thin, settled, or damaged after decades in a hot attic, and foam seals best sprayed directly against the attic floor or roof deck. Removal is checked during the free inspection and included in the quote when it's needed, so there are no surprise line items later.
For most Del City attics, open-cell is the value pick: it air-seals completely, costs less per inch, and reaches the Oklahoma R-38 ceiling target at about 10.5 inches. Closed-cell (about R-6.5 per inch) makes sense where attic depth is limited, anywhere moisture resistance matters, or in a crawl space. The free inspection settles which fits your roof and your budget.
Most attic jobs are finished in a day, including prep and cleanup. Crawl space jobs on Del City's pier-and-beam homes are usually a day as well. The crew will advise on ventilation and re-entry timing for your specific job before spraying starts.
