Sherman Insulation serves Anna, TX with attic insulation, blown-in insulation, spray foam, and crawl space services. We work throughout Collin County and respond to new requests within one business day.

Most homes in Anna's newer subdivisions were built with attic insulation that meets minimum code but falls short in practice when North Texas summer heat pushes attic temperatures past 130 degrees. Our attic insulation service brings those R-values up to where they need to be, reducing the load on your HVAC system and lowering energy bills through the long cooling season.
Blown-in insulation is the most efficient way to upgrade attic performance in Anna's production builder homes. It lays over existing material in most cases, requires no tearout, and can be installed in a single day. For an attic that simply needs more depth to meet current R-value standards, blown-in cellulose or fiberglass is the right call.
For Anna homes with rim joists, crawl spaces, or accessible wall cavities that need both insulation and air sealing, closed-cell spray foam handles both in a single application. It is also a strong option for the older in-town properties near Anna's historic center where gaps and air leakage are a bigger factor than they are in new construction.
Collin County clay soil releases ground moisture seasonally, and homes in Anna with vented crawl spaces are directly exposed to that cycle. Crawl space insulation paired with a vapor barrier stops moisture from migrating up into the floor system and reduces the humidity levels that make cooling less efficient during summer.
Newer Anna subdivision homes can have meaningful air leakage at attic penetrations, recessed lights, sill plates, and duct chases even when they look well-built from the outside. Air sealing those points before adding insulation keeps the upgrade from losing performance through air movement and is a standard part of how we approach attic work here.
Anna's older homes - the ones near the original town center that predate the recent subdivision growth - are the properties where retrofit insulation makes the biggest difference. These homes were often built before modern R-value requirements and benefit from a full assessment of the attic, walls, and floor system before selecting the right approach.
Anna has been one of the fastest-growing cities in Collin County over the past decade, with the population climbing from around 8,000 to well over 20,000 as families moved north along the US-75 corridor. That growth brought entire neighborhoods of production builder homes - houses put up quickly by large builders using standard floor plans and builder-grade materials. These homes are well-constructed and comfortable when new, but the attic insulation in many of them was installed to meet the minimum code requirement at the time of construction, not to perform optimally through fifteen to twenty North Texas summers. Homeowners who moved in five to ten years ago are now seeing that gap show up on their energy bills as their insulation begins to age and compress.
The older parts of Anna - the streets closer to the original town center that predate the recent subdivision wave - have a different set of challenges. These homes were built before modern R-value standards existed and often have minimal insulation in the attic and none in the walls. Collin County clay soil adds a shared problem across both old and new homes: the soil swells in wet seasons and shrinks in summer heat, creating seasonal movement at slab edges that allows both moisture and air to enter the building envelope. Spring storms in this part of Texas can also drop large hail that damages roofing and accelerates insulation degradation in the attic below the affected area.
Our crew works throughout Anna regularly, and we understand the local conditions that affect insulation work here. The newer subdivisions off Rosamond Parkway and the streets going up on the east side of town are where we handle the most attic upgrade calls - homes that are five to fifteen years old and performing below expectations in summer. The jobs are consistent: builder-grade blown-in or batt that needs to be supplemented with additional depth and, in many cases, air sealing at the attic penetrations first. The older properties near Anna High School and Anna ISD are more varied, and we approach those with a full assessment before recommending a scope.
Anna sits along US Highway 75, the main road that connects the city to Melissa, TX to the south and Sherman to the north. According to U.S. Census data, the large majority of Anna homes are owner-occupied single-family houses, and the city's median household income reflects families who are investing in their properties for the long term. We also serve Van Alstyne, TX to the north, which has seen a similar growth pattern and faces the same builder-grade insulation challenges in its newer subdivisions.
Reach us by phone or through the online estimate form. We respond within one business day and schedule your assessment at a time that works for you - mornings, afternoons, whatever fits your schedule.
We measure existing attic insulation depth, inspect crawl spaces or other areas of concern, and give you an exact cost for the recommended work before anything is scheduled. No obligation to proceed - just an honest picture of where your home stands.
Our crew handles setup, installation, and cleanup. A typical blown-in attic job on an Anna home takes four to six hours. We confirm the timeline at the assessment so you know exactly what to plan for.
We walk you through the finished work before we leave and answer any questions. If anything comes up after the job, you have a direct line to our team - not a call center.
We serve Anna, TX and the surrounding Collin County area. Free on-site estimates, no pressure, and a response within one business day.
(903) 294-5640Anna is a fast-growing city in Collin County, about 45 miles north of Dallas along US Highway 75. It has grown from a small agricultural community into one of the more active residential markets in North Texas, with new subdivisions going up across the city at a pace that has more than doubled the population over the past decade. The city is served by Anna ISD, and Anna High School is a central gathering point for the community. Families here tend to be owner-occupants who chose Anna for its schools, its relatively affordable home values compared to closer-in Dallas suburbs, and its position along the US-75 corridor that makes commuting practical.
The housing stock in Anna is mostly single-family homes built after 2000, many of them on typical suburban lots with brick veneer exteriors, attached two-car garages, and concrete driveways. Homes sit on Collin County clay soil - the same heavy black clay that covers much of North Texas - which swells and shrinks with the seasons and is the leading cause of foundation movement in the area. The older streets near the original town center have a different character: smaller lots, homes with more age on them, and property that has not changed hands as recently as the newer subdivisions. We serve homeowners across both parts of Anna, as well as the neighboring community of Melissa, TX, which sits just to the south and has seen a similar growth pattern along the highway corridor.
