Fast, Reliable Duct Repair & Sealing Across Antelope
Duct repair and sealing in Antelope typically runs $180-$650 depending on the scope, and most jobs are completed in a single visit. If your home in 95843 was built during the late-1980s to mid-1990s buildout, there’s a strong chance your original flex duct system is now 30-40 years old and showing it. We answer calls from Antelope Crossing, the Walerga Road corridor, and throughout the 95843 ZIP code with same-day or next-day scheduling, and a live person picks up the phone 24 hours a day at (855) 401-6006. Our technicians know the area’s housing stock because we’ve been working these subdivisions since they were new.
Why Bellows Air Duct & Vent Co. of California Is Antelope’s Preferred Duct Repair & Sealing Company
We’ve been serving Sacramento County homeowners since 1984, and Antelope has been part of our route for decades. The company was built on a simple idea: show the honest price before you start, do the work right, and stand behind it without making the customer fill out forms. That approach has earned us a strong local reputation across the communities we serve, including Antelope.
Our response time to Antelope is typically same-day or next-day because our technicians are already working nearby in Foothill Farms, North Highlands, and Citrus Heights. We don’t route calls through an app or voicemail. A real person answers, schedules the appointment, and confirms the upfront price before any truck rolls.
What matters most to Antelope homeowners is that we understand their specific housing stock. These aren’t custom homes with metal ductwork. They’re 1,400-2,400 square foot tract homes with long flex duct runs through unconditioned attics that hit 140°F or higher every summer. We’ve replaced and sealed enough of these systems to know where they fail and why.
Every job is camera-inspected before and after. You see what we see. And our 90-Day Done Right Promise means if something isn’t right, we return at no charge. No paperwork, no arguing.
Our Duct Repair & Sealing Services in Antelope
Flex Duct Repair
Flex duct repair is the service we perform most often in Antelope. The original fiberglass flex duct in these 1986-2002 tract homes was never designed to survive 35 years of Sacramento attic heat cycling. We regularly find partial collapses, detached plenum connections, and micro-tears that pull conditioned air into the attic while drawing insulation fibers and debris back into the supply stream. Our crew repairs the damaged sections, reattaches connections with mechanical fasteners, and seals everything with mastic so it holds.

Mastic Sealant Application
Mastic sealant is the only proper way to seal duct joints in Antelope’s climate. Tape dries out and fails within a few seasons of attic heat exposure. We brush on professional-grade mastic at every joint, plenum connection, and penetration point. In Antelope’s continuous cooling season - May through October with minimal breaks - a sealed system can improve delivered airflow by 20-30% and reduce the load on your air handler. One honest price shown before we start. No bait coupons.

Metal Duct Repair
Some Antelope homes, particularly a few custom builds and later infill properties, have galvanized metal ductwork. Where we find rusted sections, separated seams, or failed dampers, we patch or replace the affected runs. Metal duct holds up better to heat but corrodes where condensation collects. We inspect with a camera, show you the damage, and quote the repair before cutting anything.

Duct Insulation
Duct insulation is critical in Antelope because of those 140°F+ attic temperatures. Uninsulated or degraded flex duct acts like a radiator in reverse, warming your cooled air before it reaches the register. We install proper R-6 or R-8 insulation on replacement and repair sections, and we can reinsulate existing metal runs where the original wrap has compressed or torn. The goal is simple: the temperature at the vent should match the temperature at the air handler.

Trusted Brands We Service in Antelope
We carry repair materials and equipment from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors specify for residential ductwork. For Antelope homeowners, this means we don’t have to order parts and come back. Our trucks are stocked with flex duct in standard diameters, mastic, mechanical fasteners, and insulation wrap. Most repairs are completed in a single visit by background-checked, uniformed technicians. If your system uses Honeywell or Aprilaire components, we service those too.
Common Duct Repair & Sealing Problems We See in Antelope Homes
- Flex duct detachment at the plenum. In the Antelope Crossing neighborhood, our crew found a 1989-built home where the flex duct at the plenum had detached and partially collapsed, drawing attic insulation and rodent debris into the air stream. We sealed the plenum with mastic and reattached the ducts, restoring proper airflow and filtration. This failure mode is driven by 35 years of Sacramento attic heat cycling.
- Micro-tears from extreme attic temperatures. Original fiberglass flex duct in Antelope’s unconditioned attices regularly faces 140°F+ conditions. The liner degrades, develops pinholes and tears, and leaks conditioned air into the attic. Your system runs longer, your bills climb, and your comfort drops.
- Sagging duct supports creating low spots. Original support straps fail over time, allowing flex duct to sag between joists. These low spots trap dust, moisture, and debris. In Antelope’s winter Tule fog season, when homes stay sealed tight for weeks, microbial growth can develop in these accumulations.
- Wildfire smoke particulate infiltration. Because Antelope sits in the northeastern corner of Sacramento County, it is among the first communities to receive smoke and ash fallout from Sierra Nevada foothills wildfires. That particulate cycles directly into aging duct systems that run almost continuously through summer, embedding in torn flex duct and bypassing filtration through unsealed joints.

FAQs - Duct Repair & Sealing in Antelope
A typical duct repair for an 1,800 square foot Antelope tract home runs $280-$650 depending on whether we’re sealing joints, replacing sections, or both. Most homes in this size range need plenum reattachment plus mastic sealing at multiple joints, with occasional flex duct section replacement. Call (855) 401-6006 for a free estimate - we’ll give you an exact number before any work begins.
Repair is usually the right call for a 1990 Antelope home if the flex duct is intact but leaking at joints and plenum connections. Full replacement becomes necessary when multiple sections have collapsed, the inner liner is shredded, or rodent damage is extensive. We camera-inspect first and show you exactly what we’re seeing. Many 1990 builds need strategic repairs and sealing rather than full replacement, which saves thousands. Call for a free second opinion on any written estimate.
Sealing torn flex duct and detached plenum connections will significantly reduce wildfire smoke infiltration, but it won’t eliminate smoke odor if particulate has already embedded in porous duct liner or your HVAC filter is saturated. We recommend duct sealing combined with our air quality and sanitizing service for homes that have experienced heavy smoke events. The sealed system prevents new infiltration; sanitizing addresses what’s already inside. Call (855) 401-6006 to discuss both steps.
Most home warranties in Antelope cover ductwork only when a covered component failure causes the damage, not for age-related deterioration or poor initial installation. We provide detailed written documentation and photos from our camera inspection if you need to file a claim, but we do not bill home warranty companies directly. Our $89 Seasonal Tune-Up can identify issues before they become warranty disputes. Call for details.
Most duct repairs in Antelope’s standard 1,400-2,400 square foot tract homes take 2-4 hours and are completed in a single visit. Attic access through a hallway or garage entry is usually straightforward in these slab-on-grade homes. We schedule morning or afternoon windows and call when we’re en route. You’ll know the timeframe before we start.
