Stephenville Insulation is an insulation contractor serving Hillsboro and Hill County with home insulation, attic upgrades, spray foam, and air sealing for owner-occupied homes throughout the county seat and surrounding area. We have served this region since 2018 and respond to every inquiry within one business day.

Hillsboro has a high rate of owner-occupied homes, and many of those houses were built before modern insulation standards were in place. A proper home insulation assessment covers the attic, walls, and any crawl space under the floor - because Hill County homes often lose energy from multiple directions at once, not just one.
Hillsboro summers regularly exceed 95 degrees F for weeks at a stretch, and an attic with compressed or aging insulation turns into a heat sink that radiates directly into the living space below. Homes built in the 1950s through 1980s - which make up a large portion of the housing stock here - were insulated to R-values well below what North-Central Texas now requires, and a blown-in upgrade to R-38 or higher is the most cost-effective improvement most of these homes can get.
Older Hillsboro homes with irregular framing cavities, additions, or non-standard construction present gaps that standard batt insulation cannot fill reliably. Spray foam seals and insulates in a single application, making it the right choice for rim joists, around the attic hatch, and in any area where air sealing and insulation need to happen at the same time.
The clay soil under Hillsboro homes expands and contracts every season, and that movement gradually opens gaps at the sill plate, around plumbing penetrations, and along the foundation perimeter. Air sealing those pathways before adding insulation is the step most contractors skip - and leaving it out means a newly insulated attic still leaks conditioned air around the clock.
Many of Hillsboro's older homes sit on pier-and-beam foundations, which means there is a crawl space open to outdoor air and ground moisture below the living floor. Insulating and sealing that crawl space reduces drafts through the floor, protects floor framing from moisture damage, and makes the home measurably warmer in winter - a real difference in a house where the floors have always felt cold.
Pier-and-beam homes in Hillsboro are exposed to ground moisture through the crawl space floor, and Hill County's clay soil retains water after rain for weeks at a time. A properly installed ground vapor barrier limits the moisture that evaporates up into the floor assembly, reducing the risk of wood rot, mold in the subfloor, and the musty smell that older homes develop when the crawl space is not managed.
Hillsboro is the county seat of Hill County, and it has one of the most stable, long-term owner-occupied housing markets in North-Central Texas. That stability means the homes here have been lived in and maintained for decades - but it also means a large share of the housing stock is old enough to have been built under insulation standards that look nothing like what is recommended today. Homes built before 1970 in this area were typically insulated with fiberglass batts at code-minimum thicknesses, and many of the pier-and-beam homes from that era have crawl spaces that have never been properly sealed or insulated. Summer heat in Hill County reaches the mid-to-upper 90s F from June through September, and an under-insulated older home works the air conditioning hard for months at a stretch - which is why energy bills in these houses tend to be noticeably higher than newer construction nearby.
Hill County's clay soil creates a different kind of problem that is less visible but just as consequential. Expansive clay swells when wet and shrinks when dry, and that seasonal movement puts ongoing stress on foundations, sill plates, and the building envelope. For pier-and-beam homes, the movement affects the framing directly. For slab homes in newer parts of Hillsboro, it opens small gaps at the perimeter that allow conditioned air to escape and outdoor air to enter continuously. Spring in this part of Texas also brings severe thunderstorms - hail large enough to damage roofing is a regular occurrence in Hill County - and water intrusion from a storm-damaged roof will saturate attic insulation and reduce its performance long after the roof is repaired. Addressing the insulation immediately after any water event is important, not just the structural repair.
Our crew works throughout Hillsboro regularly, and we understand the local conditions that affect insulation work here. The older neighborhoods near downtown - some with homes dating back to the late 1800s and early 1900s - have construction details that newer crews are not used to handling. We are familiar with the pier-and-beam framing, original wood siding, and non-standard cavity depths common in pre-war Hillsboro houses, and we approach those jobs differently than a cookie-cutter subdivision in a newer suburb.
Hillsboro sits at the junction of Interstate 35 and I-35W, one of the most-traveled highway intersections in Texas, which means the city draws commuters and residents from across Hill County who depend on local contractors to get work done while they are away. We work independently and do not require the homeowner to be present for the full job - we confirm the access arrangement during the estimate visit. The Hill County government offices handle building permits for projects in unincorporated parts of the county, and the City of Hillsboro handles permits for work inside city limits. We coordinate permit applications for any job that requires one.
We also serve neighbors to the east in Corsicana, TX, which sits about 45 miles east of Hillsboro along US Highway 22 and has a similar older housing stock that needs the same kind of attention. For homeowners closer to the Metroplex, we cover Cleburne, TX as well, which is about 30 miles north of Hillsboro on US Highway 67.
Call us or use the contact form and we will respond within one business day. We ask basic questions about the home - age, square footage, foundation type - so we can prepare for the visit before we arrive.
We come out, inspect the attic, crawl space if applicable, and any problem areas you have noticed. We give you a written estimate with a firm price before we leave - no pressure, no surprise add-ons after the work starts.
We schedule the work at a time that is convenient for you and confirm the timeline in advance. Most Hillsboro attic jobs take a single day, and we do not require you to be home for the full duration once access is arranged.
When the work is done, we walk through what was completed, show you the finished areas, and answer any follow-up questions. You will have documentation of the installed R-values and materials used for your records.
We serve Hillsboro and Hill County with free on-site estimates and no-pressure quotes. One call or message and we will be in touch within one business day.
(254) 362-0219Hillsboro is the county seat of Hill County, located about 65 miles south of Dallas and 35 miles north of Waco along Interstate 35. The city of roughly 8,000 people is one of the most stable communities in North-Central Texas - most residents are long-term homeowners, and the housing stock reflects generations of owner-occupied living. Downtown Hillsboro is anchored by the historic Hill County Courthouse, a landmark built in 1890, and the surrounding neighborhoods include some of the oldest residential streets in the region. The Hillsboro Premium Outlets, located just off I-35, is the city's most prominent commercial landmark and draws shoppers from across the region. Single-family homes on modest lots make up almost all of the residential inventory, ranging from craftsman-style houses near downtown to brick ranch homes built through the mid-20th century.
The surrounding Hill County is a mix of small-town residential, agricultural land, and rural properties spread across the rolling terrain between the Metroplex and Central Texas. As the county seat, Hillsboro is the service hub for communities throughout the county, and most Hill County residents come into town for government services, healthcare, and contractors. Homeowners in outlying areas around Hillsboro face the same clay soil conditions and weather patterns as those in town - severe spring storms, intense summer heat, and occasional hard winter freezes that expose weaknesses in older building envelopes. Our neighbors in Godley, TX to the northwest and Corsicana, TX to the east deal with the same regional climate and soil conditions, and we serve all of these communities regularly.
