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 Galt
Duct sealing in Galt typically runs $450 – $1,200 for a whole-house seal depending on attic access and how much of the system needs mastic work, and most jobs are scheduled within a week with a written price locked before we start. We’re the Duct Sealing in Galt crew that Sacramento County homeowners call when the back bedrooms won’t hold temperature and the utility bill keeps climbing. Our technicians drive out from the Sacramento dispatch office with Rotobrush and Nikro equipment, background-checked and uniformed, ready to work on the ranch homes near Lincoln Way or the newer tracts off Twin Cities Road. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Galt’s Preferred Duct Sealing Company
We’ve been working in Galt long enough to know the difference between the original town core’s 1960s ranch homes with sagging flex duct and the Emerald Park, River Oaks, and Cambridge Estates subdivisions where builder-grade attic runs start leaking inside five years. Our Duct Sealing team doesn’t quote over the phone for Galt jobs because we’ve learned that the taped collar connections in those east- and south-edge tracts almost always need camera verification first.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No waiting until Monday to schedule. When you call (361) 326-5060, you talk to a human who knows Galt’s zip code 95632 and can get you on the calendar for Galt Dryer Vent Cleaning or any of our services.
Every job gets a written price before any work starts, backed by our 365-Day Done Right Promise. If the seal fails within a year, we come back at no charge. That includes a free second visit. Roy Castellanos built this standard into Hollis Air Duct Cleaning when we joined the Garrison Partners family in 2004, and it hasn’t changed.
Duct Insulation in Galt
Duct Insulation in Galt is usually the second half of a sealing job, not a standalone service, because uninsulated or poorly insulated flex duct in a 140°F attic wastes whatever cooling your sealed joints are saving. We see this most in the 1990s – 2000s tracts where builders ran thin-sleeve flex through rafter bays without wrapping the trunk lines. When the insulation compresses or rodents tear it, the metal or flex underneath sweats in Delta-humid shoulder seasons and bleeds BTUs all summer.
A typical duct insulation job in Galt runs $300 – $800 on top of sealing, depending on linear feet of attic trunk and whether we’re re-wrapping or replacing degraded flex. We use mastic-sealed collars and professional-grade insulation wrap rated for Sacramento County attic extremes.
When Insulation Matters More Than Sealing
Sometimes the joints are tight but the duct is bare. In Galt’s older ranch homes near C Street, we’ve found original metal duct with asbestos-wrap remnants where the insulation has fallen away completely. We handle the abatement referral, then return to seal and insulate with modern materials.
Rodent-Damaged Wrap
Fall rat pressure from the Delta sloughs doesn’t just chew flex. They tunnel through insulation for nesting material. We strip the damaged wrap, inspect the duct underneath, seal any punctures, then re-insulate with rodent-resistant sleeve. The Garrison Code requires us to photograph before and after. You’ll see what we saw.
HVAC Duct Sealing in Galt
HVAC Duct Sealing in Galt starts with a pressure test and camera inspection, not a sales pitch, because the specific failure modes here demand it. We pressurize the system, measure static loss, then run a borescope through the attic runs to find crushed flex, disconnected collars, or rodent damage that a simple smoke test would miss. The actual sealing uses duct mastic at every joint and collar, reinforced with mesh on larger gaps, not tape. Tape cooks off in a 140°F Galt attic inside two summers. Mastic doesn’t.
Whole-house HVAC duct sealing in Galt typically costs $450 – $1,200. Partial sealing of a single zone or repair of specific disconnected runs runs $200 – $500. We write the price down before we open a tool case.
The Camera-First Rule
We don’t quote sealing prices over the phone for Galt calls. Too many times we’ve found that “poor airflow” is actually a flex run crushed against a truss or chewed through by rats. Quoting a seal job without looking would be guessing. Our technicians carry Nikro inspection cameras on every truck.
Negative-Air Containment
When we open a Galt duct system that’s full of construction dust or rodent debris, we run the work under negative air with HEPA filtration so nothing blows into your living space. This is standard on every Hollis job, not an upsell. The equipment comes from Abatement Technologies and Nikro, the same brands commercial remediation crews use.
Trusted Brands We Service in Galt
We stock parts and materials from Honeywell, Aprilaire, and Abatement Technologies for Galt homeowners, which means most seal and insulation jobs finish in one visit without waiting on Sacramento supply-house runs. Our trucks carry Honeywell media filters and Aprilaire humidifier pads because Galt’s dry summer air and hard-running AC systems destroy cheap fiberglass filters in six weeks. When we seal your ducts, we’ll also check what filtration you’re running and tell you honestly if it’s loading your newly sealed system with too much static pressure. We don’t sell what you don’t need. We fix what the builder left wrong.
Common Duct Sealing Problems We See in Galt Homes
- Tape failure at flex collars. Builder crews in Galt’s 1990s – 2000s tracts used foil tape, not mastic, at collar connections. Two summers in a 140°F attic and the adhesive turns to powder. We find supply air leaking into the attic instead of reaching the bedrooms, and homeowners wonder why the AC runs constantly.
- Crushed flex runs in newer attics. The Emerald Park and River Oaks subdivisions have tight truss spacing where installers rammed flex duct through gaps too small. The duct kinks, airflow drops, and the system compensates by running longer. We re-route or replace the crushed section, then seal properly.
- Rodent chews in fall. Every October, Galt’s Delta farmland and sloughs push rats into residential attics. They chew flex duct behind registers and at trunk splits, opening leaks that look like poor craftsmanship but are actually wildlife damage. Sealing over a chewed run without repair hides the hole and traps droppings inside.
- Construction debris loading the system. New builds in Cambridge Estates and similar tracts often have drywall dust, wood chips, and paint overspray in the supply and return ducts at handover. This debris coats the blower wheel and evaporator coil, raising static pressure until even a visually “sealed” joint starts leaking under load. We clean before we seal.

FAQs About Duct Sealing in Galt
Builder-grade flex duct in Galt’s 2000s tracts was taped at collars, not mastic-sealed, and attic heat cycling plus fall rat pressure from the Delta sloughs destroys tape joints within five to ten years. A 2005 build is right in the failure window. Call (361) 326-5060 for a camera inspection and written estimate.
We can seal them only after repairing or replacing the chewed section, because mastic over a hole just hides it. We inspect with a camera, cut out damaged flex, splice in new material, then seal and insulate. The 365-Day Done Right Promise covers our repair and seal work for a full year. Call (361) 326-5060 to schedule.
It helps by preventing your return ducts from sucking unfiltered attic air into the system, but sealing alone doesn’t remove dust already inside. Most Galt homes need sealing plus rotary brush cleaning because the fine Delta silt and grass pollen coat the duct interior and load the blower motor. We typically do both. Call (361) 326-5060 for a combined quote.
Check for rooms that never reach thermostat temperature, utility bills that spike in July and August, or dust blowing from registers right after the AC kicks on. In Galt’s newer tracts, also sniff for drywall dust smell from the return grille. Those are signs of disconnected collars or construction debris in the system. We confirm with a pressure test and camera. Call (361) 326-5060.
Most Galt homes do best with MERV 8 – 11 pleated filters changed every 60 – 90 days. MERV 13 and above loads the blower with too much static pressure in a system that may already have partial blockages from Delta dust. After we seal and clean your ducts, we’ll test static pressure and recommend the right filter for your specific system. Call (361) 326-5060 to schedule.
