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.

AfterFast, Reliable Duct Sealing Across Fairview
Duct sealing in Fairview typically runs $800 – $2,400 for a whole-house system, with most hillside ranch homes falling in the $1,200 – $1,800 range depending on whether we’re sealing accessible trunk lines or chasing crushed flex runs behind the air handler. We’re the crew that Fairview homeowners call after a PSPS shutoff fills their house with wildfire smoke, because sealing is what actually keeps that smoke out the next time the Diablo Winds blow.
Our dispatch and scheduling runs through the Dallas-Fort Worth office, but our techs serve Fairview directly. We know the difference between a flatland dust call and a hillside smoke-intrusion job. Homes along Fairview Avenue, the canyon roads off Palomares, and the older ranch builds tucked into the East Bay hills have duct problems that flatland contractors rarely see: original galvanized trunk lines from the 1960s, flex duct crushed by decades of settling, and registers that have been disconnected since the last homeowner “fixed” things themselves. When you call (361) 326-5060, a live person answers, and we’ll get you a written price before any work starts.

Our techs are background-checked and uniformed, and they work under 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. No estimate that balloons once we’re inside. No per-vent pricing games. One flat price per system, agreed before work starts.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday when your house still smells like smoke from last week’s PSPS event.
HVAC Duct Sealing in Fairview
HVAC Duct Sealing in Fairview is not about summer dust or pollen, the way it is in the hot Central Valley. Here in the East Bay hills, sealing is a smoke-defense measure. Fall and winter Diablo Winds push wildfire smoke and ash directly into Fairview’s canyons, and PG&E’s Public Safety Power Shutoffs cut HVAC power exactly when that smoke is worst. Many homeowners, trying to “clear the air,” run their furnace fan on generator power or battery backup, and pull contaminated outside air straight through leaky return ducts, spreading ash through every room.
Our sealing process starts with a camera inspection of the full duct run, including the flex lines behind the air handler that no homeowner can see. We pressurize the system, measure leakage at the trunk lines, registers, and plenum connections, then seal with mastic and mechanical fasteners rated for the temperature swings these hillside systems see. For homes with older galvanized duct, we often find that “sealing” actually requires partial replacement of disconnected or corroded sections, and we’ll tell you that before we start, not after.
Smoke-Season Sealing Protocol
Fairview’s real duct threat arrives October through March, not July. We seal to create positive pressure integrity: when your system runs, filtered air goes out, unfiltered smoke does not come in. This means sealing the return side as carefully as the supply side, which many contractors skip.
Generator and Backup Power Considerations
Homes on private wells and septic, common in unincorporated Alameda County pockets like Fairview, often run furnace fans on portable generators during PSPS events. A sealed duct system protects that limited power investment by reducing the runtime needed to maintain clean air. An unsealed system just recirculates contamination.
Duct Repair in Fairview
Duct Repair in Fairview usually means fixing what decades of hillside settling, original construction shortcuts, and amateur handyman work have left behind. The 1950s – 70s ranch homes that dominate Fairview’s flat areas and lower hills often have galvanized steel trunk lines with corroded seams, while the custom hillside builds along the canyon roads have flex duct runs that have been crushed behind air handlers or pulled loose at registers by the weight of their own insulation over forty years.
We price repair by the actual condition we find, not by a per-vent formula. A typical repair job in Fairview runs $400 – $1,200 for reconnecting and sealing disconnected runs, replacing crushed flex sections, or patching corroded galvanized seams. If the trunk line itself has failed, replacement of that section runs $1,500 – $3,000 depending on accessibility. We put the full scope and price in writing before any cutting or sealing begins.
Camera-First Diagnosis
We run a borescope through every accessible duct section before quoting repair. In a hillside home off Palomares Road last season, the camera revealed a flex run that had been completely detached from the plenum for years, dumping conditioned air into the crawlspace while the homeowner paid to heat dirt. No amount of register-sealing would have fixed that.
Galvanized Trunk Line Restoration
Older Fairview homes with original galvanized duct often have seams that were never sealed at installation, only taped. The tape dries and falls off. We remove the failed tape, clean the metal, and apply mastic sealant with reinforcing mesh, then test under pressure to confirm the fix holds.
Trusted Brands We Service in Fairview
Our equipment roster includes professional-grade tools that match what commercial crews use: Rotobrush rotary brush systems and Nikro negative-air machines for cleaning and pre-seal preparation, plus filtration products from Honeywell and Aprilaire that we specify for Fairview’s smoke-season needs. We stock replacement flex duct, register boots, and mastic supplies locally so repair jobs don’t wait on parts. For homes needing upgraded filtration during Diablo Winds season, we size and install Honeywell and Aprilaire media filters and electronic air cleaners that actually fit your existing return, not generic inserts that gap at the edges.
Common Duct Sealing Problems We See in Fairview Homes
- Original flex runs crushed behind the air handler. In hillside builds along Fairview’s canyon roads, flex duct was often routed through tight framing cavities with no support. Decades of gravity and vibration compress the duct flat. The system still “works,” but airflow is strangled and the fan pulls harder, drawing smoke through every leaky joint.
- Galvanized seams that were never properly sealed. Fairview’s mid-century ranch homes commonly have trunk lines where the installer relied on friction fit and a strip of cloth tape. The tape is dust now. Smoke and ash flow freely through these gaps when the Diablo Winds pressurize the crawlspace or attic.
- Registers disconnected from duct boots by amateur repairs. We find this constantly in older homes: a previous owner “fixed” a noisy register by pulling the duct loose and never reconnecting it properly. Conditioned air dumps into the wall cavity. During PSPS events, that same gap pulls smoke backward into the system.
- Homeowner fan cycling that contaminates freshly cleaned ducts. After a smoke event, Fairview residents often run the furnace fan continuously to “clear the air” before ducts are sealed. This pulls ash through return leaks and deposits it throughout the supply side, undoing any recent cleaning and making sealing more urgent, not less.
Pricing for Duct Sealing in Fairview, TX
A typical whole-house duct sealing job in Fairview runs $800 – $2,400. Most 1,200 – 2,000 square foot ranch homes with accessible crawlspaces fall in the $1,200 – $1,800 range. Hillside builds with multiple air handlers, crushed flex runs requiring replacement, or galvanized trunk lines needing section repair can reach $2,000 – $3,500.
What moves the price: accessibility (crawlspace vs. finished basement), duct material age and condition, and whether we’re sealing existing intact runs or repairing disconnected and crushed sections first. We do not quote per-vent pricing. One flat price per system, written down before work starts, and it does not change at the door.
Camera inspection and full system testing are included in every sealing quote. If we find that sealing alone won’t solve your smoke intrusion problem, we’ll show you the camera footage and explain exactly what repair is needed and why. Estimates are free. Call (361) 326-5060 to schedule.

FAQs About Duct Sealing in Fairview
Yes, sealing matters more than cleaning if your goal is keeping wildfire smoke out. Cleaning removes existing ash and debris, but without sealing, the next PSPS event or Diablo Winds cycle pulls new contamination through the same leaks and contaminates your supply ducts within hours. We recommend sealing after cleaning for Fairview homes, not instead of it, because the two jobs address different problems. Call (361) 326-5060 and we’ll inspect both conditions and quote accordingly.
We run a borescope camera through every accessible section of duct before quoting any sealing work. In Fairview’s 1950s – 70s ranch builds and custom hillside homes, we commonly find flex runs crushed behind the air handler, registers disconnected from boots inside wall cavities, and galvanized seams that have separated completely. The camera shows us exactly where the breaks are, so we seal what needs sealing and repair what needs repairing, with no guesswork. Call (361) 326-5060 to schedule a camera inspection.
Because an unsealed return duct system pulls outside air through every leak in your crawlspace or attic, and during Diablo Winds events that outside air is loaded with wildfire smoke and ash. The fan distributes that contamination evenly through every supply register in your house. On a canyon-side ranch off Fairview Avenue, the homeowner ran the furnace fan all night during a PSPS event to “clear the air” and ended up pulling east-wind ash and smoke through the return ducts and spreading it across the whole house. Our techs did a camera inspection, found several flex runs crushed behind the air handler and disconnected at the registers, then sealed the joints and reconnected the runs under negative pressure with HEPA filtration. The next smoke event, the house stayed noticeably cleaner. Sealing first, then running the fan, is the correct order.
Yes. Many Fairview homes need repair before sealing can be effective. Original galvanized trunk lines may have corroded through at the seams. Flex runs may be crushed or detached. We repair or replace failed sections, then seal the intact system, and we price both phases in writing before starting. The 365-Day Done Right Promise covers the complete job: if any sealed joint fails or repaired section separates within a year, we return and make it right at no charge, including a free second visit. Call (361) 326-5060 for an exact scope and price.
MERV 13 or higher pleated media filters, properly sized with no edge gaps, are the minimum for Diablo Winds smoke events. For homes with members who are sensitive to particulates, we specify and install Honeywell and Aprilaire electronic air cleaners and high-capacity media cabinets that integrate with your existing return duct. The filter only works if the duct around it is sealed, a gap at the filter rack or return plenum bypasses even the best filter entirely. We test seal integrity at the filter location on every job. Call (361) 326-5060 and we’ll assess your current setup.
