Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Duct Sealing Across Pinehurst
Duct sealing in Pinehurst, TX typically runs $450 – $1,200 for a whole-house seal depending on system size and accessibility, and most jobs are completed in a single visit. If you’re living on one of the wooded half-acre lots off Pinehurst Avenue or in the older sections near the old Pinehurst School, your home’s original galvanized ductwork is likely leaking 20 – 30% of conditioned air into the attic, crawlspace, or basement. That’s heated air you’re paying for all winter while your windows stay shut from October through April, and cooled air you’re losing to the summer humidity that breeds musty odors in below-grade duct runs.
We dispatch crews to Pinehurst from our Dallas-Fort Worth coordination office, and our technicians know the local housing stock: the 1950s – 1970s Capes and ranches with short duct runs, few returns, and those narrow 6-inch galvanized pipes that newer franchises often damage because they’re trained on flex duct. We’ve also worked the 1980s – 2000s Colonials going up in newer sections. Roy Castellanos and our Duct Sealing team have sealed systems in Pinehurst homes where the original asbestos tape on basement trunk lines is crumbling, and where return ducts were undersized for modern 3-ton systems and got crushed above finished basements.

Why Hollis Air Duct Cleaning Is Pinehurst’s Preferred Duct Sealing Company
Pinehurst homeowners don’t need another company that treats their town like a zip code on a route sheet. We’ve sealed ducts on the dead-end streets off Pinehurst Avenue where the return chases are too narrow for modern equipment, and in the older sections near the old Pinehurst School where crushed runs hide above drop ceilings that haven’t been opened in forty years. That local knowledge means we show up with the right tools and don’t waste your time figuring out what Pinehurst homes are built like.
Our reputation here is built on The Garrison Standard: arrive inside the quoted window, price in writing before touching anything, complete the job by the book, and leave the site clean. Every technician is background-checked and uniformed, and you’ll know who’s coming before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops. The 365-Day Done Right Promise covers every seal we perform; if it fails within a year, we return and make it right at no charge, including a free second visit. That’s not a slogan. It’s written on every job.
We also handle Air Duct Cleaning in Pinehurst and Dryer Vent Cleaning in Pinehurst, so if your inspection turns up multiple issues, one crew can address them without coordinating separate visits.
Duct Insulation in Pinehurst
Duct Insulation in Pinehurst addresses a specific problem: those original galvanized trunk lines in your basement or crawlspace, often still wrapped in failing asbestos tape, lose massive thermal energy through metal walls that have no barrier against the cold winter ground or summer humidity. When your furnace runs for six months straight with windows sealed against nor’easters, uninsulated ducts in unconditioned spaces are radiating heat you paid for into the dirt. In summer, the same metal sweats in humid basement air, feeding the musty odors that Pinehurst homeowners notice when they first switch on the AC in May.
A typical duct insulation job in Pinehurst runs $600 – $1,400 depending on linear feet of accessible trunk line and whether we’re working around hazardous tape that requires abatement protocols. We use professional-grade materials from Abatement Technologies and Guardsman, not hardware-store wrap that compresses and fails within two seasons.
Basement and Crawlspace Applications
Most Pinehurst homes built before 1980 have supply trunks running through unfinished basements or crawlspaces below grade. We install closed-cell insulation with a vapor barrier rated for below-grade moisture exposure, sealed with mastic at every joint. The goal is stopping thermal loss and condensation, not just covering metal with a sleeve.
Return Chase Upgrades
On the dead-end streets off Pinehurst Avenue, we frequently find return chases that were never insulated because they were originally wall cavities, not dedicated ducts. We line these with rigid board insulation where accessible, or recommend full replacement if the chase is too compromised to seal effectively.
HVAC Duct Sealing in Pinehurst
HVAC Duct Sealing in Pinehurst is the core fix for the leakage that plagues these mid-century systems. Your blower is designed to push air through sealed pathways to your registers. When gaps at joints, disconnected runs, or rusted-out sections let that air escape, your system works harder, your bills climb, and rooms stay unevenly heated or cooled. In Pinehurst’s climate, where windows stay shut from October to April and recirculated air carries months of dust, pet dander, and humidifier moisture, leaky ducts also pull in attic dust and crawlspace odors that contaminate what you’re breathing.
We seal with mastic compound and fiberglass mesh at every joint, register boot, and plenum connection, plus mechanical fastening where the original installation has failed. A typical whole-house HVAC duct sealing in Pinehurst runs $450 – $1,200. We don’t price per vent or hit you with add-ons once the van is in your driveway; one flat price per system, agreed in writing before work starts.
Pressure Testing Before and After
Every seal job includes a duct blaster test to quantify leakage in CFM25, measured before we start and after we finish. You’ll see the number drop. We document it, explain it, and leave the report with you. No guesswork, no “trust us, it’s better.”
Accessing Hidden Damage
In Pinehurst’s older sections, we regularly find disconnected runs buried above finished basements where the original installer never expected access. We cut precise access panels, seal the damage, and restore the finish. If we need to open more than we estimated, the price we wrote down still governs.
Trusted Brands We Service in Pinehurst
Our trucks carry sealing and insulation materials from Aprilaire, Abatement Technologies, and Guardsman, plus rotary brush systems from Rotobrush for jobs where cleaning precedes sealing. We don’t order parts after we arrive; our Dallas-Fort Worth warehouse stocks the mastics, meshes, and board insulation these Pinehurst jobs require, so turnaround is same-visit, not next-week. When your basement trunk line needs insulation rated for below-grade moisture, or your register boots need high-temperature mastic that won’t crack after one heating season, we’re not running to a supply house. That matters in Pinehurst, where the iron-rich well water and forced-air systems create that distinct reddish dust coating every supply run, and where failing asbestos tape demands materials that can be applied safely alongside abatement protocols.
Common Duct Sealing Problems We See in Pinehurst Homes
- Rusted galvanized trunks leaking at seams. Pinehurst’s original 6-inch galvanized pipes, installed in the 1950s through 1970s, have decades of rust and scale buildup. The seams were never designed to last seventy years, and we regularly find pinhole leaks and separated joints that newer flex-duct crews don’t recognize until they’ve made them worse.
- Crushed return ducts above finished basements. The dead-end streets off Pinehurst Avenue and the older sections near the old Pinehurst School often have return chases that were undersized when homeowners upgraded to modern 3-ton systems. We find crushed or fully disconnected runs hidden above drop ceilings, a quirk you rarely see in neighboring towns with newer construction.
- Failing asbestos tape on basement and crawlspace lines. Original trunk line insulation was asbestos tape, now crumbling and creating both a health hazard and a thermal loss point. We work with certified abatement protocols where required, then seal and reinsulate with modern materials.
- Reddish well-water dust infiltrating supply runs. With a huge share of Pinehurst homes on private wells, the dry, iron-rich water combines with forced-air systems to create a distinct reddish dust that coats every supply run. Leaky return ducts pull this dust from basements and crawlspaces, depositing it through your registers.
