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 Town and Country
Most Town and Country homeowners don’t realize they’re heating and cooling their crawlspaces until the utility bill arrives. Duct sealing in Town and Country typically runs $450 – $1,200 for a full system, and our Duct Sealing crew can usually assess your leaks and give you a written price the same visit. We dispatch from our Seattle office, but we’ve been sending crews east to Town and Country long enough to know the difference between a 1968 ranch off Country Homes Boulevard and a new build near the Spokane River bluff. That local knowledge matters because the fix for galvanized steel ductwork with failing tape joints isn’t the same as the fix for a disconnected flex duct in a million-dollar attic. Call (361) 326-5060 and we’ll put you on the schedule.
Why Hollis Air Duct Cleaning Is Town and Country’s Preferred Duct Sealing Company
We’ve earned our reputation in Town and Country the slow way, one job at a time. Roy Castellanos built Hollis Air Duct Cleaning on The Garrison Standard, which means showing up inside the window we promised, pricing in writing before touching anything, and leaving the site clean. Our technicians are background-checked and uniformed, and our phones are answered by a live person 24 hours a day, 7 days a week.
Town and Country isn’t a generic suburb to us. We know the older neighborhoods near Whitworth University where original duct systems pull dust through crawlspace leaks, and we know the newer estates off Five Mile Road where multi-zone systems hide disconnected runs behind finished ceilings. That specificity shows up in our work. We also handle Air Duct Cleaning in Town and Country and Dryer Vent Cleaning in Town and Country, so when we’re already in your home, we can spot problems across the full system.
Every repair we perform carries our 365-Day Done Right Promise in writing. If the seal fails or the leak returns within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.
Duct Sealing Services in Town and Country
Duct Sealing Services in Town and Country address the conditioned air you’re losing through gaps, disconnected joints, and deteriorated tape in your forced-air system. In our local market, a typical whole-home duct sealing job runs $450 – $1,200 depending on system size, accessibility, and whether we’re working with original galvanized steel or modern flex duct. Most Town and Country homeowners call us after noticing hot or cold rooms, dust blowing from registers even when the system’s off, or utility bills that climbed without explanation.
Leak Detection and Pressure Testing
We start with a visual inspection and, where appropriate, a pressure test to quantify how much air your ducts are bleeding into the attic or crawlspace. In Town and Country’s older ranches, we regularly find return plenums pulling 15 – 20% unconditioned air from the crawlspace through gaps around filter racks. That isn’t just inefficient, it’s pulling fiberglass, rodent droppings, and crawlspace dust straight into your living space.
Mastic Sealing and Mechanical Reconnection
For accessible leaks, we brush on duct sealing mastic, a water-based sealant that remains flexible and won’t degrade like foil tape. Where flex duct has pulled off collars or registers, we resecure with mechanical connections and seal the joint. We don’t use duct tape, the gray cloth stuff from the hardware store, because it fails within months in Town and Country’s temperature swings.

Duct Insulation in Town and Country
Duct Insulation in Town and Country protects the air you’ve already paid to heat or cool as it travels through unconditioned spaces. In eastern Washington’s climate, attic ducts can lose 10 – 30% of their thermal energy through bare metal or thin factory insulation. A typical duct insulation job in Town and Country runs $600 – $1,800 depending on linear footage and whether we’re wrapping existing duct or replacing degraded insulation. Homeowners with bonus rooms that never reach temperature, or systems that run constantly in July and January, usually benefit most.
R-Value Upgrades for Attic and Crawlspace Runs
We install foil-faced fiberglass or closed-cell insulation wraps rated for the temperature extremes Town and Country sees, from single-digit winter nights to 100-degree August afternoons. In homes near the Little Spokane River where humidity can spike seasonally, we specify materials that won’t absorb moisture and collapse against the duct.
Insulation Replacement After Rodent Damage
Our crews regularly find shredded insulation in crawlspaces off Assembly Street and the older neighborhoods south of Francis Avenue. We remove the contaminated material, seal the underlying duct, then reinsulate with fresh product. The work is priced as a separate line item on your written estimate, so you know exactly what you’re paying for.
Trusted Brands We Service in Town and Country
We stock parts and materials from Aprilaire, Abatement Technologies, and Guardsman, the same filtration and sealing products commercial HVAC contractors specify. For Town and Country homeowners, that means faster turnaround, no waiting for Seattle supply houses to ship east. When we find a failed Aprilaire zoning damper or a collapsed Guardsman flex duct during a sealing job, we can usually complete the repair the same visit rather than rescheduling. Our equipment roster also includes Rotobrush rotary brush systems and Nikro negative-air machines for jobs where sealing follows cleaning.
Common Duct Sealing Problems We See in Town and Country Homes
- Crawlspace dust infiltration in mid-century ranches. The original galvanized steel ductwork in 1960s and 1970s homes near Country Homes Boulevard and the Whitworth area was sealed with fabric tape that degrades after 40 years. Once the tape fails, the return side pulls fine dust, construction debris, and occasionally rodent activity directly into the airflow.
- Disconnected flex ducts in newer luxury homes. In the estates off Five Mile Road and along the bluff, we’ve found flex duct that pulled completely off trunk lines because installers used zip ties instead of proper mechanical connections. The room gets no airflow, the homeowner cranks the thermostat, and the system runs itself to death.
- Wildfire smoke residue accelerating seal degradation. Town and Country’s proximity to Spokane means regional fire seasons deposit fine ash and particulates inside ductwork. That ash is abrasive and chemically active, it breaks down tape adhesives and collects at leak points, making existing gaps worse over time.
- Filter rack gaps pulling unconditioned air. In both old and new homes, we find return filter racks that were never properly sealed to the duct. The system draws attic or crawlspace air around the filter, bypassing it entirely and pressurizing the gap with dust.
Pricing for Duct Sealing in Town and Country, WA
We don’t do per-vent pricing or teaser coupons that balloon once we’re in your driveway. A typical duct sealing job in Town and Country runs $450 – $1,200 for a full system, with most single-story ranches falling in the $500 – $800 range and larger multi-zone homes reaching $1,000 – $1,200. Duct insulation adds $600 – $1,800 depending on linear footage. What moves the number: how much of your duct is accessible, whether we’re repairing disconnected sections or just sealing joints, and whether insulation replacement is part of the scope.
