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 Riverside
Duct sealing in Riverside, CT typically runs $450 – $1,200 for a whole-home system depending on access and the extent of leakage, and most jobs are completed in a single visit with a written price agreed before any work begins. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family since 2004, and our Duct Sealing in Riverside crews dispatch from our Hartford office to serve homeowners throughout this shoreline community.

Call (361) 326-5060 for a free estimate, or read on to see what separates a proper sealing job from a tape-and-hope patch.
Why Hollis Air Duct Cleaning Is Riverside’s Preferred Duct Sealing Company
We’ve built our reputation in Fairfield County on The Garrison Standard: arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean. In Riverside specifically, that means technicians who understand how the salt air off Long Island Sound affects metal ductwork in older homes, and how the freeze-thaw cycles common to this part of Connecticut stress flexible duct runs in attics. Our background-checked, uniformed technicians are accountable and verifiable, and every repair we perform is backed by our 365-Day Done Right Promise in writing. If the seal 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, seven days a week, so you’re never left in a voicemail loop when you’ve got a duct leak bleeding heated air into your attic in January.
HVAC Duct Sealing in Riverside
HVAC Duct Sealing in Riverside addresses the conditioned air escaping through gaps, disconnected joints, and deteriorated seals in your home’s duct network, which in this area often means metal trunk lines from the 1950s – 1970s or flexible duct retrofitted into older colonials. We see the worst leakage in homes near the water, where decades of humidity cycling have corroded tape adhesives and loosened connections in crawlspaces and basements. A typical whole-home sealing job in Riverside runs $450 – $950 for accessible systems, while homes with ductwork buried behind plaster or requiring substantial access work can reach $1,000 – $1,200. We use mastic sealant and mechanical fasteners, not duct tape, because tape fails within months in the temperature swings your attic experiences.
What the Process Involves
We pressurize your duct system and measure leakage with a calibrated fan, then mark every gap. Our Duct Sealing team applies professional-grade mastic, reinforced with mesh where joints have separated, and tests again to verify the reduction. You’ll see the before-and-after numbers on the invoice.
When Riverside Homeowners Need It Most
Call us when rooms stay cold despite a running furnace, when your energy bill spikes without explanation, or after any renovation that disturbed walls or ceilings. In Riverside’s older homes near the village center, we’ve found original ductwork that was never properly sealed during installation, bleeding 30% or more of heated air into unfinished spaces.
Duct Repair in Riverside
Duct Repair in Riverside fixes physical damage, collapsed flexible runs, rusted metal sections, and improperly supported sags that restrict airflow, problems we encounter frequently in the split-level and ranch homes built during the 1960s and 1970s housing boom along this stretch of the Connecticut coast. Repair costs in Riverside typically range from $250 – $600 for localized fixes such as replacing a damaged flexible run or patching a corroded metal section, while more extensive reconstruction of a trunk line or multiple branch repairs can run $700 – $1,200 depending on material and access. We carry sheet metal, flexible duct, and connectors appropriate for the mix of systems found in Riverside homes, and we never start cutting until you’ve approved the written price.
Collapsed and Restricted Runs
Flexible duct in Riverside attics often gets crushed by storage boxes or sags where straps have failed, choking airflow to distant rooms. We replace the damaged section with properly supported new material and seal all connections with mastic.
Corrosion and Rust-Through
Metal ducts in homes near the Sound show accelerated corrosion from decades of humid basement and crawlspace conditions. We cut out the rotted section, fabricate a replacement from galvanized stock, and seal it into the existing system without disturbing surrounding finishes where possible.
Trusted Brands We Service in Riverside
We maintain parts and materials from Honeywell, Aprilaire, and Abatement Technologies for filtration and air quality components tied to your duct system, and our sealing equipment includes professional-grade mastic applicators and pressure-testing gear from Rotobrush and Nikro. For Riverside homeowners, that means no waiting on special orders for common repairs, and technicians who arrive with the right materials to complete most jobs in one visit. We also stock Guardsman filtration products when your sealing project reveals a need for upgraded return-air filtration, which is common in homes near the I-95 corridor where road particulate loads are higher.
Common Duct Sealing Problems We See in Riverside Homes
- Failed tape at metal joints in pre-1980 homes. The original cloth-backed tape used in Riverside’s older colonials and capes has dried and detached, leaving gaps at every trunk-line connection. We remove the residue and apply mastic rated for the temperature range your attic reaches.
- Disconnected flexible duct in attic retrofits. Homes in the Glenville and North Mianus areas often had central air added in the 1980s and 1990s with flexible duct strung through hot attics. The connections work loose over time, and the insulation degrades. We re-secure and seal with proper supports.
- Leaky return-air pathways pulling in basement or crawlspace air. In Riverside’s hillside homes with walkout basements, we find return chases that draw musty air through gaps in the building envelope. Sealing these pathways improves air quality and system efficiency simultaneously.
- Condensation damage at cold-air returns. The temperature differential between Riverside’s heated interiors and unconditioned basement spaces creates moisture at metal duct seams, accelerating corrosion. We seal and insulate these vulnerable points to break the cycle.
Pricing for Duct Sealing in Riverside, CT
A typical whole-home duct sealing in Riverside runs $450 – $950 for systems with reasonable attic or basement access, while complex jobs requiring drywall repair, extensive crawlspace work, or reconstruction of damaged trunk lines range from $1,000 – $1,200. Single-room or partial-system repairs start around $250 – $400. Your price depends on three factors: how much of the system we can reach without destructive access, the condition of existing materials, and whether we’re addressing sealing alone or sealing plus repair of physical damage. We provide a written, itemized price before any work begins, and that price does not move at the door. No per-vent pricing, no surprise add-ons, no bait-and-switch. Call (361) 326-5060 for a free estimate, we’ll inspect your system, and you’ll know exactly what you’ll pay before we start.
