Sunland Park Insulation is an insulation contractor serving Anthony, NM with blown-in insulation, attic insulation, and air sealing services, operating from Sunland Park since 2017. We work throughout Dona Ana County and respond to every new estimate request within one business day.

Most homes in Anthony were built between the 1970s and 1990s with ranch-style layouts that have low-slope roofs and attics that have never been touched. Our blown-in insulation service fills those attics efficiently, reaching around irregular framing and existing ductwork without tearing anything apart.
Anthony summer temperatures regularly push past 100 degrees F, and the intense UV at this elevation breaks down building envelopes faster than homeowners expect. Spray foam insulates and air seals in one step, delivering the biggest reduction in heat gain for stucco homes where hot outdoor air pushes in through every small gap.
The Mesilla Valley sun bakes rooftops hard from late spring through early fall, and Anthony homes with aging or undersized attic insulation feel it in every room below the ceiling. Bringing attic insulation up to the depth recommended for Climate Zone 3B is the single highest-return upgrade most Anthony homeowners can make before the next summer arrives.
The desert winds that move through the Anthony area in spring push fine dust through every unsealed gap around light fixtures, ceiling penetrations, and the top plate. Air sealing closes those pathways before insulation goes in, which cuts both energy loss and the constant dust accumulation that frustrates homeowners throughout the valley.
Many Anthony homes were built on slab foundations with little wall insulation and codes that were far more lenient than what is required today. Retrofit insulation upgrades those homes without a major renovation, improving comfort and reducing cooling costs in houses that were never built for today's energy prices.
Anthony homes with crawl spaces face a particular challenge during monsoon season, when fast-moving runoff across flat desert lots can push moisture against foundations and under homes. A properly installed vapor barrier keeps ground moisture out of the crawl space and away from the floor framing above it.
Anthony sits in the Mesilla Valley at the southern end of New Mexico, where summer temperatures regularly exceed 100 degrees F and the area averages over 290 sunny days per year. At this latitude and elevation, UV exposure is intense enough to degrade exterior stucco, roofing materials, and caulk faster than homeowners expect. The monsoon season from July through September brings the valley's annual rainfall in concentrated bursts - and because the surrounding desert soil does not absorb water quickly, that rain moves fast across flat lots and can pool against foundations or find its way into crawl spaces before the ground dries out. An insulation contractor who works here regularly understands that the job is not just about adding material; it is about sealing the building against both heat and water infiltration.
The housing stock in Anthony is made up almost entirely of single-family homes, most of them built between the 1970s and 1990s. These are ranch-style houses on modest lots with stucco exteriors, slab foundations, and flat or low-slope rooflines - a building type that works well in dry heat but ages poorly when the original insulation is never upgraded. Many of these homes were built to energy codes that are well below what is recommended today for Climate Zone 3B, which means a homeowner living in a 1980s Anthony house is very likely losing a significant amount of conditioned air through the ceiling every day. Addressing that gap pays off in lower electric bills and rooms that actually reach the temperature on the thermostat.
Our crew works throughout Anthony regularly, and insulation permits for projects that require them are handled through the Dona Ana County building department, since Anthony is an unincorporated community with no city permit office of its own. The ranch-style stucco homes on flat valley lots that we find throughout Anthony are exactly the type of construction we work on most often, and we understand how these homes age in the Chihuahuan Desert heat and dust.
Anthony is best known to locals and visitors alike for the Texas-New Mexico state line that runs right through the middle of the community - and for the celebrated identity as the New Year's Capital of the World, a point of pride on both sides of the border. The community sits in the flat valley floor south of the Franklin Mountains, with Interstate 10 running through town as the main connection to El Paso to the south. We cover all of Anthony, from homes near Anthony Gap at the state line to neighborhoods further north toward the valley farmland.
When scheduling jobs in this part of the valley, we also serve the neighboring community of Dona Ana, NM to the north and Santa Teresa, NM to the west - if you have a neighbor in either of those communities who has asked about insulation work, we are already familiar with the area.
When you call or send a message, we ask a few basic questions about your home - age, rough square footage, and what problems you have noticed. We respond to every new estimate request within one business day.
We come to your Anthony home, look in the attic, and measure what is already there. This visit is free, takes about 30 to 45 minutes, and results in a clear written estimate with no pressure to sign on the spot.
The crew seals air gaps first, then installs the insulation. For a typical Anthony ranch-style home, the job takes one full day. You can stay home - the work is contained to the attic or treated area.
Before we leave, we walk you through the finished work so you can see exactly what was done. If any questions come up after the job, we are reachable and stand behind our work.

(575) 266-8167Anthony, NM is an unincorporated community in Dona Ana County with a population of around 9,000 to 10,000 residents. It sits on the flat floor of the Mesilla Valley, part of the Rio Grande corridor that runs through southern New Mexico and into Texas, with the Franklin Mountains visible to the south near the Texas state line. The community is made up mostly of owner-occupied single-family homes on modest lots, and residents have strong roots in the area - many families have lived here for generations. Because Anthony is unincorporated, county services handle roads, zoning, and building permits rather than a city hall.
Anthony is perhaps best known for straddling the Texas-New Mexico state line - the community shares its name and its main road with Anthony, TX directly to the south, and the state line runs through the heart of the area. Locals on both sides of that line know each other, and the shared identity is a real part of community life here. The housing stock is dominated by ranch-style stucco homes built from the 1970s through the 1990s, many of which still carry their original insulation. Neighbors throughout the area also call us for work in Anthony, TX and in Chaparral, NM to the east - so if you have friends or family in those communities, we serve those areas too.
