Stephenville Insulation provides wall insulation, attic upgrades, spray foam, and crawl space work for homeowners throughout Cleburne and Johnson County. We have served this part of North Texas since 2018 and follow up on every request within one business day.

A large share of Cleburne homes built from the 1950s through the 1970s have exterior wall cavities that were never insulated or filled with materials that have long since lost their effectiveness. Upgrading wall insulation through a retrofit process is one of the highest-impact improvements available for older Johnson County homes, and it makes a noticeable difference in how the home feels in both summer and winter.
Cleburne summers are long and hot, and inadequate attic insulation allows heat to pour into the living space from above throughout June, July, and August. Homes built before 1990 typically need their attic insulation brought up to current R-value recommendations to give the HVAC system a fair chance of keeping up during peak summer heat.
For Cleburne homes with crawl spaces, uninsulated rim joists, or areas where both air sealing and thermal resistance are needed at the same time, spray foam is the most effective solution. Older homes in Johnson County with pier-and-beam foundations benefit especially from spray foam applied to the crawl space perimeter, where ground moisture and outside air are the primary problems.
Many homes in Cleburne's established neighborhoods sit on raised or pier-and-beam foundations with open crawl spaces that allow ground moisture, pests, and cold winter air to reach the floor system. Insulating and vapor-sealing the crawl space eliminates a significant source of energy loss and protects the wood framing from the seasonal moisture cycles common in Johnson County's clay soils.
Adding blown-in insulation to the attic floor is the fastest and most affordable way to increase R-value in a Cleburne home with an open attic. It works on top of existing material, does not require the home to be vacated, and can be installed in a single day for most single-family homes. For homes where the existing insulation is too degraded to be worth topping off, removal and replacement comes first.
Johnson County's clay soils hold moisture and release it slowly, which means crawl spaces under Cleburne homes deal with ground moisture year-round - not just during the rainy season. A properly installed vapor barrier stops that moisture at the soil level before it can migrate upward into insulation, floor joists, and subfloor materials.
Cleburne was founded in 1867 and has been the county seat of Johnson County ever since. That history means a large share of the city's housing was built 50 to 100 years ago, and much of it has never received a meaningful insulation upgrade. Homes built in the 1950s, 1960s, and 1970s were typically insulated to standards that are a fraction of what current energy codes require, and the materials used - thin fiberglass batts, early blown-in cellulose, or nothing at all in wall cavities - have degraded further over the years. Add North Texas summers that routinely push temperatures above 95 degrees for weeks at a time, and the result is high energy bills, HVAC systems that never catch up, and living spaces that feel warm no matter how low you set the thermostat. Cleburne's housing also skews toward owner-occupied single-family homes, meaning most residents here are long-term homeowners who stand to benefit directly from a properly insulated building envelope.
The clay soils throughout Johnson County are another factor that distinguishes insulation work in Cleburne from what you encounter in cities with more stable ground. The soil expands when it absorbs rain and contracts sharply during dry summers, and that movement is continuous - every year, small new gaps open around foundations, rim joists, and utility penetrations that allow outside air to bypass insulation entirely. This is why air sealing is as important as R-value in this market. Cleburne also experienced significant damage from the February 2021 winter storm, and some homes in the older neighborhoods still have crawl spaces and pipe runs where insulation and vapor barriers were damaged and never fully replaced. Addressing those gaps matters not just for comfort but for protecting the home from the next hard freeze event.
Our crew works throughout Cleburne regularly, and we understand the local conditions that affect insulation work here. Cleburne has a housing mix that runs the full range - from the older brick homes in the established neighborhoods around the Johnson County Courthouse on the historic downtown square, to mid-century construction throughout the core neighborhoods, to larger properties on the city's edges that border rural Johnson County. Each type requires a different approach, and we have worked on all of them.
Cleburne is a working-class homeowner city with a strong local identity - major employers like BNSF Railway keep many families here long-term, and the result is a population that invests in their properties rather than treating them as short-term rentals. We take that same long-term view on every job we do in this city. We also serve Alvarado, TX just to the north along US 67, and Burleson, TX further up toward the Metroplex, so we have regular coverage of southern Johnson County and the communities between Cleburne and Fort Worth.
If you are not sure what your Cleburne home needs, start with a free in-home estimate. We inspect the attic, wall access points, and crawl space where applicable, and give you a written quote on the spot - no ballpark numbers, no follow-up call to negotiate the price.
Call us any time or use the contact form. We follow up within one business day. We ask a few short questions about your home and the issues you are experiencing so we arrive prepared for the estimate visit.
We visit your Cleburne home, inspect the attic, wall cavities, and crawl space as applicable, and evaluate what is currently in place. You receive a written quote before we leave - the price you see is the price you pay.
Most blown-in and batt insulation jobs in Cleburne finish in a single day. Wall retrofit work typically runs one to two days depending on scope. Spray foam projects require the treated space to be vacated for 24 hours after application.
After the job is complete, we walk through the finished work with you, answer any questions, and confirm you are satisfied with the result before we leave the property.
We serve all of Johnson County and the surrounding area. No pressure, no obligation - just an honest look at your home and a written quote.
(254) 362-0219Cleburne is the county seat of Johnson County and the largest city in the county, with a population of around 32,000 people. Founded in 1867, the city has one of the older neighborhood grids in the region - streets near the historic downtown square and the Johnson County Courthouse are lined with homes that date to the early and mid-1900s. The housing stock throughout the city is predominantly single-family detached homes on modest in-town lots, with larger rural-edge properties appearing as you move toward the county lines. Most residents are long-term homeowners, and the city has a stable, working-class character anchored by employers like BNSF Railway, which operates a major locomotive repair facility here and employs a significant share of the local workforce.
For outdoor recreation, Cleburne residents have access to Cleburne State Park, a Texas state park just outside the city with a lake, camping, and hiking trails that is a well-known local destination. The city also has Pat Cleburne Lake on its east side, used for events and recreation by residents from across Johnson County. Whether your home is in an older neighborhood near the historic downtown square or out toward the edge of town, we serve all of Cleburne and the surrounding area. We also regularly work in Alvarado, TX just up the road, and Godley, TX to the northwest.
