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 Cheney
Duct sealing in Cheney typically runs $450 – $1,200 for a whole-home system, with most jobs completed in a single visit. Our crews serve Cheney from the Seattle office, dispatching with Rotobrush and Nikro equipment to homes from the historic downtown grid to the rental corridors near Eastern Washington University. Call (361) 326-5060 for a written estimate before any work starts.
We’ve worked in Cheney long enough to know the difference between a post-WWII ranch on the north side with original sheet-metal ductwork and a 1980s rental conversion on the south side with flex duct strung through an unconditioned crawlspace. That local knowledge matters because the sealing approach, the materials we bring, and the problems we expect to find are different in each. Cheney’s older housing stock, its student-rental turnover cycle, and the blowing Palouse dust that settles into every gap and seam create duct-sealing challenges you won’t find in Spokane’s more established owner-occupied neighborhoods. Our Duct Sealing team treats those conditions as standard operating procedure, not surprises to pad a bill.
Why Hollis Air Duct Cleaning Is Cheney’s Preferred Duct Sealing Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004, and our Cheney work 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. That discipline matters in a market where landlords and property managers need documented service with photo reports they can show tenants or owners.
Our technicians are background-checked and uniformed. You know who is walking into your home before they arrive. Every job gets a written price that does not move at the door, and every repair is covered by our 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge, including a free second visit.
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 for someone to confirm your appointment. For Duct Sealing in Cheney, that responsiveness matters when you’re coordinating around a tenant move-in or trying to solve a heating problem before winter break ends.
Duct Insulation in Cheney
Duct Insulation in Cheney addresses a specific problem: heated or cooled air escaping through thin or deteriorated duct walls before it ever reaches your registers. In Cheney’s climate, with winter temperatures regularly dropping below 20°F and summer heat pushing attic temperatures past 120°F, uninsulated duct runs in basements, crawlspaces, and attics waste energy and create uneven temperatures from room to room. A typical Duct Insulation job in Cheney runs $600 – $1,400 depending on the linear footage of exposed duct and the accessibility of the spaces where it runs.
When Insulation Beats Sealing Alone
Some Cheney homes need insulation more than sealing, or both. Original sheet-metal ducts in post-WWII ranches often have intact seams but no thermal barrier, so the air cools 10 – 15 degrees before reaching a bedroom on the north side of the house. We wrap those runs with formaldehyde-free fiberglass insulation jacket, sealed at every joint, to maintain the temperature the furnace produced.
Rental Conversions and Unconditioned Spaces
The 1970s-80s rentals near EWU are a different case. Flex duct run through crawlspaces often lacks both proper sealing and adequate insulation. In August turnover cleanings, we regularly find condensation on cold duct surfaces in humid crawlspaces, which leads to mold and degraded insulation. We replace the damaged wrap and seal all connections with mastic before reinsulating.
HVAC Duct Sealing in Cheney
HVAC Duct Sealing in Cheney closes the gaps, cracks, and disconnected joints that leak conditioned air into spaces where it does no good. A typical whole-home HVAC Duct Sealing job in Cheney costs $450 – $1,200, with simpler single-zone repairs starting around $350. The price depends on the duct material (sheet metal, flex, or fiberboard), the number of joints and connections, and whether we need to access crawlspaces or sealed chases to reach the problem areas.
Sheet-Metal Seams in Older Homes
Post-WWII Cheney homes with original galvanized ductwork develop gaps at longitudinal seams and transverse joints over decades. We seal those with water-based duct mastic, brushed into every seam, not tape that will peel in Cheney’s temperature swings. The mastic remains flexible through freeze-thaw cycles and cures to a hard, durable seal.
Flex Duct Reconnection and Support
On the south side near campus, we find crushed, sagging, or completely disconnected flex runs in crawlspaces where previous maintenance was minimal. We support the duct properly with strapping, reconnect it with mechanical fasteners and mastic, and verify airflow at every register before we leave. Our Nikro negative-air machines pull debris from the line during the process.
Trusted Brands We Service in Cheney
We stock parts and materials from Rotobrush, Nikro, and Abatement Technologies for Cheney jobs, which means faster turnaround and no waiting for a Seattle warehouse shipment to seal a rental before move-in weekend. Our rotary brush systems handle the agitation needed to prep old metal seams for sealing. Our negative-air equipment maintains proper containment when we’re working in occupied homes. For filtration upgrades after sealing, we carry Honeywell, Aprilaire, and Guardsman products sized to the systems we commonly see in Cheney’s modest single-family homes and duplexes.
Common Duct Sealing Problems We See in Cheney Homes
- Unheated vacant rentals crack sealants. When EWU students leave for winter break and landlords set thermostats to 50°F, duct sealants in 1970s-80s rentals experience thermal stress without the moderating effect of regular airflow. We return to those same properties in January to find mastic joints and tape seams that held fine in October now leaking heated air into crawlspaces.
- Palouse dust infiltrates return ducts. Cheney’s late-summer wheat harvest kicks up fine dust that finds every gap in poorly sealed return plenums. We see filters clog prematurely and blower motors strain because the return side is pulling unfiltered air from basements and wall cavities, not just the conditioned space.
- Original sheet-metal seams gap after decades. The post-WWII housing stock on Cheney’s north and east sides often has ductwork installed when Truman was president. Those longitudinal seams were sealed with fabric tape and paste that has dried, cracked, and failed. Rodents and insects enter through gaps near crawlspace vents, leaving debris that circulates through the system.
- DIY flex duct repairs fail. Landlords and previous tenants have sometimes attempted repairs with hardware-store foil tape that won’t adhere to dusty flex duct in Cheney’s temperature extremes. We remove those failed attempts and install proper mechanical connections with mastic-rated for the application.
Pricing for Duct Sealing in Cheney, WA
Whole-home duct sealing in Cheney typically runs $450 – $1,200. Single-zone repairs or partial sealing start around $350. Duct Insulation jobs range $600 – $1,400 depending on linear footage and accessibility. What moves the price: the amount of duct we can reach without demolition, whether we’re repairing disconnected runs or just sealing joints, and whether the job includes access panel installation for future maintenance.

FAQs About Duct Sealing in Cheney
Cheney’s roughly 40% renter-occupied housing stock, driven by Eastern Washington University student turnover, means units sit vacant and unheated between tenants, causing thermal stress on duct sealants that owner-occupied Spokane homes rarely experience. Landlords also face compressed timelines between tenants that prioritize quick fixes over proper sealing, so accumulated problems surface faster. Call (361) 326-5060 for an exact quote on your rental property.
Late-summer and fall wheat-field dust on the Palouse infiltrates poorly sealed return ducts and settles at joint gaps, accelerating sealant degradation and contaminating indoor air. We address this by sealing the return side first, then verifying with negative-air testing that the system pulls only from conditioned space. Call (361) 326-5060 for an exact quote.
We inspect original sheet-metal seams for dried paste failure, check for sagging flex duct in basement conversions, and verify that crawlspace vents aren’t creating pressure differentials that pull unfiltered air through gaps. Our camera inspection documents every finding before we quote. Call (361) 326-5060 for an exact quote.
Yes, by closing the gaps at seams and connections where rodents and insects enter duct runs, though we always recommend addressing the crawlspace access or vent screening that allowed entry in the first place. Sealing alone won’t remove existing debris; we typically combine sealing with source removal using Rotobrush agitation and Nikro negative-air containment. Call (361) 326-5060 for an exact quote.
The busiest weeks are early August and late December, before fall move-in and after winter break, when landlords need documented service completed fast for new leases. We schedule these periods first-come, but our live-answer phones and local parts stock help us meet tight windows that out-of-area competitors often miss. Call (361) 326-5060 for an exact quote.
