Longview Insulation Company provides insulation contractor services in Marshall, TX - including spray foam, attic insulation, and commercial insulation - and serves Harrison County homeowners and business owners with free on-site estimates and replies within 1 business day.

Marshall has a mix of commercial buildings, retail properties, and institutional facilities - many of them aging - that lose significant conditioned air through under-insulated walls and ceilings. Our commercial insulation work covers everything from warehouses and office suites to the older brick commercial buildings near downtown Marshall that need modern thermal performance without major structural changes.
Marshall summers push attic temperatures well above 130°F, and the heat radiates directly into living spaces in homes with thin or degraded insulation. Most of Marshall's ranch-style homes from the 1960s through 1980s were built with insulation levels that made sense for energy costs at the time - but those homes are paying for it every summer now with inflated cooling bills.
Pier-and-beam foundations are common in Marshall's older neighborhoods, and the crawl spaces under those homes are a consistent source of heat loss in winter and moisture intrusion year-round. Insulating and sealing the crawl space properly is one of the most impactful upgrades for Marshall homes built before 1975, where the floor system has often never been addressed at all.
Harrison County's humidity and heat make air sealing a critical part of any insulation project, not just a bonus. Spray foam applied to attic decks, rim joists, and crawl space walls seals gaps and insulates in one pass - a practical approach for Marshall homes with brick exteriors and wood framing that have developed air infiltration paths over decades.
Marshall receives close to 50 inches of rain per year, and the clay soils in Harrison County hold moisture for extended periods after heavy rain events. A vapor barrier under the crawl space protects floor joists and subfloor from the ground moisture that drives wood rot and mold growth in pier-and-beam homes throughout this part of East Texas.
Blown-in insulation is well-suited to Marshall's older housing stock, where wall cavities and attic floors have irregular framing and obstructions that make batt installation impractical. The loose-fill material covers every corner and gap, which matters in homes with decades of settling, added wiring, and insulation that has shifted over time.
Marshall sits deep in the East Texas Piney Woods, where summer heat and humidity arrive together and stay for months. Average highs reach the mid-90s from June through August, and the air conditioning systems in older homes run almost continuously to compensate for thermal envelopes that were built to 1960s and 1970s standards. A large share of Marshall's housing stock was constructed before 1980, and insulation from that era has been compressing, settling, and degrading ever since. Upgrading it is not a luxury - it is overdue maintenance on a system that affects every room in the house every day.
The mix of pier-and-beam and slab foundations across Marshall creates different insulation challenges depending on the home. Pier-and-beam homes - common in older neighborhoods near downtown and near the two university campuses - have open crawl spaces that lose heat in winter and let moisture in year-round. Slab-on-grade homes on the city's edges face the same surface-level insulation problems but without the crawl space variable. Both types benefit from an insulation contractor who has worked across this specific housing stock and knows what to look for on arrival, rather than applying a one-size approach.
Our crew works on homes throughout Harrison County, and Marshall is a city we know well - from the older brick homes in established neighborhoods near Wiley College to the ranch-style houses on the south and east sides of town. The Harrison County area has a higher-than-average share of pier-and-beam foundations in the older housing stock, which means our crawl space crews come prepared for access challenges and subfloor conditions that newer construction simply does not have.
Marshall is the county seat of Harrison County and draws residents from a wide surrounding area for services and commerce. The city is located along US Highway 59 and Interstate 20, and the commercial corridors along both of those routes include older industrial and retail buildings that frequently need commercial insulation upgrades. The team also serves the rural residential areas between Marshall and the Texas-Louisiana border, including communities near Caddo Lake, where pier-and-beam homes on wooded lots are especially common.
We also serve homeowners in nearby Carthage, about 30 miles south of Marshall in Panola County, where the housing stock and climate conditions are nearly identical. Homeowners in Longview, roughly 40 miles to the west, can also reach our team directly - we move between these East Texas communities regularly.
We respond within 1 business day. A quick conversation helps us understand whether we are looking at an attic, crawl space, walls, or a commercial space - so we come prepared. No commitment required to get information or a rough range.
A technician walks the space, checks the existing insulation, and measures the area. This is where we give you an honest price - no inflated figures and no pressure to decide on the spot. Most homeowners find the assessment answers the cost question quickly.
Most Marshall jobs are completed in a single day. Blown-in and batt work moves quickly once prep is done. Spray foam requires the home to be vacated for 24 hours after application - we walk through what to expect before the job starts.
Once the work is done, we walk the space with you so you can see what was installed and ask any questions. If something needs attention after we leave, call us - we stand behind the work.
We serve Marshall, TX and all of Harrison County. No pressure - just an honest assessment and a straightforward quote.
(430) 267-1839Marshall is the county seat of Harrison County in East Texas, with a population of roughly 22,000 to 23,000 people. The city is home to two four-year universities - Wiley College, a historically Black liberal arts college founded in 1873, and East Texas Baptist University - which give Marshall a stable institutional base and a diverse mix of long-term residents and student renters. The older neighborhoods near both campuses and the downtown square have some of the oldest housing in the region, with brick ranch homes and traditional-style houses sitting alongside early 20th-century wood-frame construction.
Marshall is perhaps best known regionally for its annual Wonderland of Lights festival, which draws visitors from across East Texas and beyond each November and December. Beyond the holiday season, the city serves as the commercial and services hub for Harrison County, with US Highway 59 and Interstate 20 connecting it to Longview to the west and the Louisiana border to the east. Nearby areas like Texarkana share much of the same East Texas climate and housing character, as does Carthage, the county seat of Panola County about 30 miles to the south.
