Sherman Insulation provides spray foam, attic insulation, blown-in, and crawl space services to homeowners in Van Alstyne, TX. We know this community well and respond to new requests within one business day.

Van Alstyne has a large inventory of older pier-and-beam homes near downtown where crawl space air sealing and insulation are the highest-priority upgrades. Our spray foam insulation service handles rim joists, crawl space walls, and hard-to-reach cavities in these homes in a single application that insulates and air-seals at the same time.
Many of Van Alstyne's newer subdivision homes were built with just enough attic insulation to meet code at the time of construction, which may have changed since the home was built. North Texas attic temperatures routinely top 130 degrees Fahrenheit, and upgrading to current R-value standards is the single most effective energy improvement for most Van Alstyne homes.
Blown-in insulation is a practical choice for Van Alstyne homeowners who want to improve attic performance without a major project. It installs quickly over existing material in most attics, raises R-values to current standards, and works well in the dense, compact attic spaces common in newer subdivision homes.
Older Van Alstyne homes with pier-and-beam foundations sit directly over vented crawl spaces where Grayson County clay soil pushes moisture into the floor system year-round. Crawl space insulation stops that heat and moisture transfer at the floor joists, making a measurable difference in both comfort and energy use.
Ground moisture is a consistent problem for Van Alstyne crawl spaces, especially during the wet spring months and after heavy rains. A properly installed vapor barrier across the crawl space floor stops moisture migration before it reaches the floor system, protecting insulation and wood framing alike.
Van Alstyne homes built in the 1990s and early 2000s often have significant air leakage at attic knee walls, plumbing chases, and sill plates. Air sealing those pathways before adding insulation prevents conditioned air loss in winter and stops hot attic air from cycling back into living areas in summer.
Van Alstyne has more than doubled in population over the last fifteen years, and the housing stock reflects that growth. Newer subdivisions built along US Highway 75 contain homes that were constructed to the minimum code standards of their build year - which means many of them are underinsulated by today's standards and by what North Texas summers actually demand. Families who moved here from the suburbs looking for more space and a quieter pace are often surprised to find their energy bills higher than expected. In most cases, the attic is the starting point: too little insulation, no air sealing, and an attic floor that acts more like a heat conduit than a barrier.
The older neighborhoods near downtown Van Alstyne present a different challenge. Homes in this part of town were built decades ago, and many sit on pier-and-beam foundations with vented crawl spaces beneath them. Grayson County clay soil is highly expansive, swelling with moisture in wet months and releasing that moisture as humidity as it dries out. Without a vapor barrier in the crawl space, that humidity cycles up through the floor system and into the home, degrading insulation and contributing to air quality problems. Van Alstyne also sees regular spring hailstorms that can compromise roof penetrations and attic ventilation covers, creating new air pathways into insulated spaces that go unnoticed until the next energy bill arrives.
Our crew works throughout Van Alstyne regularly, and we understand the local conditions that affect insulation work here. The range of homes in this community is wide - from older pier-and-beam houses on smaller lots near the historic downtown along Jefferson Street to newer brick-front homes in planned subdivisions on the outskirts of town. Each type needs a different approach, and we bring that local familiarity to every job. The City of Van Alstyne has been managing rapid growth carefully, and permit requirements and building standards reflect a community that is paying attention to how new construction integrates with older neighborhoods.
Van Alstyne runs along US-75, which connects it directly to Sherman to the north and McKinney and the broader Dallas metro to the south. The Van Alstyne Panthers are the local high school team, and the school district is one of the primary reasons families choose to settle here rather than in nearby towns. Most of the properties we work on here are owner-occupied single-family homes - people who are investing in their homes for the long term, not just looking for a quick fix.
We also serve Anna, TX to the south and Gunter, TX to the north - both communities along the same corridor that share similar housing patterns and climate conditions.

(903) 294-5640Van Alstyne is a city in Grayson County, about 50 miles north of Dallas along US Highway 75. It is one of the fastest-growing small cities in the region - the population has more than doubled since 2010, going from around 3,000 to over 7,000 by the early 2020s. That growth is visible in the expanding subdivisions along the highway and on the edges of town, where new brick-front homes continue to go up on what was recently open land. The older part of Van Alstyne, centered on Jefferson Street and the historic downtown, has a quieter character with smaller lots, mature shade trees, and homes that date back to the early and mid-1900s. Many of those older homes were built on pier-and-beam foundations, a detail that matters when it comes to crawl space moisture and floor insulation. For more on the city's history and layout, the Van Alstyne, Texas Wikipedia article covers the community's background.
The Van Alstyne Independent School District is the main reason many families have chosen this city over other nearby towns - the schools have a strong local reputation, and families who move here for the district tend to stay and invest in their homes for the long term. Rural-edge properties outside the subdivisions often have larger lots, outbuildings, and long driveways that reflect the area's agricultural past. The city is well-positioned on the US-75 corridor, making it easy to reach from both Sherman to the north and McKinney to the south. We also serve Anna, TX, which sits just down the highway and has a similar mix of newer suburban-style homes and long-time residents who have been in the area for generations.
