Insulation Contractor in Capitol Hill, OKC

Capitol Hill's Trusted Insulation Contractor

Capitol Hill is one of Oklahoma City's oldest and most storied neighborhoods. Stretching south of I-40 between Western Avenue and I-35, this south-central community earned its name because the Oklahoma state capitol was originally planned for this location. While the capitol ultimately landed a few miles north, Capitol Hill developed into a thriving neighborhood with its own commercial district, schools, churches, and a tight-knit community that endures to this day.

The housing stock in Capitol Hill tells the story of Oklahoma City's early growth. Most homes here were built between the 1920s and 1950s — small frame houses, many between 800 and 1,400 square feet, that were constructed long before insulation standards existed in any meaningful form. These homes have charm, character, and affordable price tags, but many of them have zero wall insulation and only a thin layer of deteriorated material in the attic. Bo's Insulation has spent years working in neighborhoods exactly like Capitol Hill, and the Bohannan brothers understand how to bring these older homes into the modern era of comfort and efficiency without disrupting the character that makes them special.

Insulation Challenges in Capitol Hill's Older Homes

Capitol Hill's housing stock presents a unique set of insulation challenges that differ significantly from newer construction elsewhere in the metro:

• Empty Wall Cavities — The majority of Capitol Hill homes were built with wood-frame construction and finished with plaster or early drywall. The wall cavities were left completely empty — no insulation at all. In summer, exterior walls radiate heat directly into living spaces. In winter, cold air passes straight through. Injection foam fills these cavities without removing interior walls, transforming comfort practically overnight.
• Pier-and-Beam Crawl Spaces — Many Capitol Hill homes sit on pier-and-beam foundations rather than concrete slabs. The open crawl space beneath the house allows cold air, moisture, and even pests to affect the home from below. Crawl space insulation with spray foam or rigid board stops cold floors in winter and helps control moisture that can lead to mold and wood rot.
• Attics with Little or No Insulation — Original attic insulation in these homes, if it existed at all, has long since deteriorated or settled to nearly nothing. Many Capitol Hill attics we inspect have less than two inches of old material — well below the R-38 to R-49 recommended for Oklahoma's climate zone. Blown-in cellulose or fiberglass brings these attics up to modern standards affordably.
• Air Leaks Throughout — Decades of settling, aging materials, and previous repairs have created countless gaps around windows, doors, electrical boxes, plumbing penetrations, and where walls meet the attic floor. Comprehensive air sealing paired with insulation is the most impactful upgrade for these homes.

Why Capitol Hill Homeowners Choose Bo's Insulation

We understand that Capitol Hill is a working-class neighborhood where every dollar matters. That is exactly why insulation is such a smart investment here — the energy savings on monthly utility bills make a real, measurable difference for families in this area. A Capitol Hill home with no wall insulation and minimal attic insulation might be spending 30 to 50 percent more on heating and cooling than necessary. Fixing that is not a luxury; it is practical financial relief.

Bo's Insulation gives Capitol Hill homeowners the same quality work and honest service we bring to every neighborhood in the metro. The Bohannan brothers personally assess each project, recommend only what your home actually needs, and never pressure you into unnecessary upgrades.

Services Available in Capitol Hill

Because most Capitol Hill homes are between 800 and 1,400 square feet, the total cost of an insulation upgrade is very manageable. A complete attic insulation job for a typical Capitol Hill home runs $1,200 to $3,000, depending on the method and current conditions. Crawl space insulation typically adds $1,000 to $2,500, and wall injection foam for a small home is often $1,500 to $3,500.

These are not luxury upgrades — they are practical investments that pay for themselves through lower OGE and ONG bills. Many Capitol Hill homeowners see their investment returned within two to four years through reduced energy costs alone. Combined with available OGE rebates for insulation upgrades, the net cost is even lower.
