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 Country Homes
Duct sealing in Country Homes typically runs $450 – $950 for a whole-home system, and most jobs are scheduled within a few days of your call. We’re the Duct Sealing crew that knows the difference between a 1962 ranch on North Wall Street and a converted shop off West Trails Road, because we’ve worked on both. Our dispatch team coordinates from the Seattle office, but the technicians who roll to Country Homes live and work in the Spokane area, so they understand why your return-air ducts smell like smoke every August and why your crawlspace flex-duct freezes solid by January. Call (361) 326-5060 for a written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Country Homes’s Preferred Duct Sealing Company
We’ve been sealing ducts in the Spokane County unincorporated pockets since 2004, long enough to know that Country Homes isn’t Spokane proper and doesn’t operate like it. The Garrison Standard means our technicians arrive inside the quoted window, price the job in writing before touching your system, and leave the site clean. Roy Castellanos built this operation on accountability, not coupons.
Country Homes homeowners call us back because we flag the problems other crews miss: the galvanized trunk line rusted through where it crosses your dirt crawlspace, the flex-duct chewed open by rodents in the garage conversion, the return plenum pulling wildfire smoke straight through a gap you can’t see from the hallway. Our 365-Day Done Right Promise covers every seal in writing. If it fails, we return 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. When you’re smelling smoke in your bedroom at midnight, you reach a human who can schedule you.
Duct Insulation in Country Homes
Duct Insulation in Country Homes addresses the heat loss and condensation that plague ranch-style homes with ducts routed through unheated crawlspaces and garages. In this semi-arid climate, winter temperatures drop below 20°F for weeks at a stretch, and bare metal or thin-walled flex-duct in a crawlspace bleeds heated air into the dirt while sweating moisture that breeds musty odors and mold. Most Country Homes properties we insulate are 1950s-1970s builds on large lots, many with original ductwork that was never wrapped. A typical duct insulation job here runs $600 – $1,400 depending on linear footage and accessibility.
Condensation and Freeze Protection
Uninsulated return ducts in Country Homes crawlspaces collect frost on their exterior during cold snaps, then drip when the furnace cycles off. We wrap with formaldehyde-free fiberglass insulation and vapor barrier, sealed at every seam, so the metal stays dry and your indoor humidity stays controlled.
Garage and Outbuilding Runs
Many Country Homes properties have informally ducted shops or converted garages. These flex-duct runs often lack insulation entirely, dumping heat into unused space and pulling cold air back into the system. We assess whether insulation alone solves it or if the run needs rerouting to conditioned space.
HVAC Duct Sealing in Country Homes
HVAC Duct Sealing in Country Homes closes the gaps, disconnected joints, and corrosion holes that leak conditioned air into attics, crawlspaces, and wall cavities. In this market, we see more smoke-damage and rodent-chewed systems than typical urban calls, because Country Homes sits downwind of regional wildfire corridors and many homes were ducted without permit oversight. A whole-home seal with mastic and reinforced tape typically runs $450 – $950; partial repairs on specific runs start around $250. We price by the system, not by the vent, and we write it down before we start.
Smoke and Ash Infiltration Sealing
Wildfire season pulls fine particulates through every gap in your duct shell. After the smoke clears, homeowners still smell it because ash settled in leaks the filter never reached. We pressurize the system, locate every breach with a smoke pencil or theatrical fog, then seal with water-based duct mastic rated for temperature cycling.
Rodent Damage and Re-entry Prevention
Country Homes’s large lots and rural edge mean mice and pack rats explore crawlspaces and garage duct runs regularly. We seal entry points with galvanized mesh and mastic, then pressure-test to confirm the system holds before we leave.
Trusted Brands We Service in Country Homes
Our trucks carry professional-grade equipment from Nikro and Abatement Technologies, plus filtration products from Honeywell and Aprilaire. For Country Homes homeowners, this means we don’t order parts from a warehouse three states away and make you wait. We stock mastic, reinforced foil tape, fiberglass insulation wraps, and replacement flex-duct in common diameters. If your system needs a Honeywell media cabinet sealed into a new return plenum, or an Aprilaire whole-house dehumidifier tied into ductwork after smoke damage, we have the components and the training to install it without a second trip. Rotobrush rotary systems and Nikro negative-air machines are on every truck for the cleaning work that often accompanies a seal job.
Common Duct Sealing Problems We See in Country Homes Homes
- Original galvanized trunk lines rusted through at crawlspace joints. The 1950s-1970s ranch homes dominating Country Homes were built with galvanized steel ducts that corrode where they contact damp soil or sit in pooled condensation. We cut out the failed section and splice in sealed duct board or properly wrapped flex, depending on access.
- Flex-duct in converted garages and shops, chewed or kinked. Informal additions are common on large Country Homes lots. Homeowners run flex-duct to a shop or garage conversion without proper support or protection, and it sags, crimps, or becomes rodent nesting material within a season.
- Return plenums pulling wildfire smoke through attic and wall gaps. During August and September, negative pressure in leaky return systems draws outside air straight past the filter. We find these breaches with pressure testing and seal them with mastic rated for the temperature swings of a Country Homes attic.
- Disconnected boots at floor registers in split-level additions. Mid-century split-levels in the neighborhood often had register boots that separated from subfloor ductwork as the original mastic dried and cracked. The gap blows conditioned air into the wall cavity until we reseat and seal the boot.
Pricing for Duct Sealing in Country Homes, WA
A typical whole-home duct sealing in Country Homes runs $450 – $950. Partial repairs on one or two compromised runs start around $250. Duct insulation, which we often recommend alongside sealing for crawlspace and garage runs, adds $600 – $1,400 depending on linear footage. What moves you within these ranges: accessibility (crawlspace height and condition), extent of damage (rodent-chewed flex versus a single disconnected joint), and whether we need to remove degraded material before sealing. Every price is written down before work starts. No per-vent pricing. No add-ons at the door. We also handle Air Duct Cleaning in Country Homes and Dryer Vent Cleaning in Country Homes if your system needs more than sealing.

Pricing is consistent across the Spokane metro.
