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.

Call us at (361) 326-5060 for a free estimate.
Cheshire Village isn’t like newer Connecticut suburbs. The colonial-era homes along Main Street, the farmhouse properties near the Cheshire Historical Society, and the vintage Cape Cods tucked behind Highland Avenue all share something: HVAC systems that were retrofitted into structures never designed for forced air. That retrofitting leaves seams, joints, and connections that loosen over decades. We’ve sealed ducts in homes where the original stone foundation dates to the 1700s and the ductwork was added in the 1980s. The mismatch shows up in your utility bills and your comfort.
Why Hollis Air Duct Cleaning Is Cheshire Village’s Preferred Duct Sealing Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Cheshire Village comes from showing up when we said we would and pricing the job in writing before we touch anything. Our 365-Day Done Right Promise covers every duct sealing repair: if the seal fails within a year, we return and make it right at no charge, including a free second visit.
Our technicians are background-checked and uniformed, and they arrive equipped with professional-grade tools from Rotobrush and Nikro. When we seal ducts near the Cheshire Academy or in the neighborhoods off Route 10, we know to check for the specific problems this village’s housing stock creates: unsealed crawlspace runs, basement moisture intrusion, and rodent-damaged flex duct in older outbuildings.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues. If you’re calling from a home near Bartlem Park or the Mixville Road area, we’ll get you scheduled.
Duct Insulation in Cheshire Village
Duct Insulation in Cheshire Village addresses a problem most homeowners don’t know they have: conditioned air bleeding into unheated spaces before it ever reaches your vents. In this village’s historic homes, supply ducts often run through original dirt-floor basements, unsealed crawlspaces, and stone-walled utility chases that stay 40 degrees in winter and 85 degrees in summer. Without proper insulation, you’re paying to heat or cool those spaces, not your living areas.
A typical duct insulation job in Cheshire Village runs $600 – $1,400 depending on linear footage and accessibility. Homes with exposed basement runs are straightforward; properties where ducts snake through finished walls or tight crawlspaces take more time and material.
When Insulation Matters More Than Sealing
Sometimes the ducts are airtight but uninsulated. We see this in Cheshire Village homes where a previous owner sealed joints with mastic but left bare metal running through a damp stone cellar. The air arrives at your registers at the right volume but the wrong temperature. Insulation fixes that. We use wrapped fiberglass with vapor barrier, sized to the duct diameter, secured with mechanical fasteners rather than tape that degrades in basement humidity.
Basement Moisture and Insulation Choice
Cheshire’s high water table means basement dampness is common, especially in older homes near the Ten Mile River watershed. Standard insulation absorbs moisture, compresses, and breeds mold. In these conditions, we specify closed-cell foam or pre-formed fiberglass with reinforced jacketing that won’t wick groundwater. Roy Castellanos, who leads our operation, insists on materials that hold up in the actual conditions we find, not the conditions a catalog assumes.
HVAC Duct Sealing in Cheshire Village
HVAC Duct Sealing in Cheshire Village closes the gaps, cracks, and disconnected joints that leak conditioned air into your walls, attic, and crawlspaces. In a typical village home, we measure 20 – 35% air loss through these leaks before we start. After sealing with mastic compound and metal-backed tape at accessible joints, plus aerosol sealant for interior duct runs, that loss drops below 5%. The difference shows up in room-to-room temperature balance and in your monthly energy costs.
Whole-home HVAC duct sealing in Cheshire Village generally runs $450 – $950. Smaller Cape Cods with basement mechanical rooms at one end of the house fall toward the lower end. Larger colonials with duct runs to a second floor and finished attic, or homes requiring crawlspace access near Highland Avenue, trend higher.
Aerosol Duct Sealing for Finished Homes
When ducts are buried behind plaster and lath, we can’t reach every joint by hand. Our aerosol sealing process pressurizes the duct system and introduces a fine polymer sealant that finds and plugs leaks from the inside. The sealant only deposits where air is escaping, so your ducts aren’t coated unnecessarily. This method is especially useful in Cheshire Village’s historic properties where opening walls isn’t practical or permitted.
Post-Sealing Verification
Every sealing job ends with a pressure test. We measure total duct leakage before and after, and we show you the numbers. If the system doesn’t meet our standard, we keep working. That’s The Garrison Standard: price in writing, work by the book, verify before we leave. No guesswork, no “trust us, it’s better.”
Trusted Brands We Service in Cheshire Village
We stock parts and materials from Abatement Technologies, Guardsman, and Rotobrush for fast turnaround on Cheshire Village jobs. When a seal requires specialized collar fittings, dampers, or access panels for tight crawlspaces, we don’t wait on freight from a warehouse three states away. Our van inventory covers the common repair scenarios we encounter in colonial and farmhouse construction, and our Hartford office maintains deeper stock for same-day pickup when needed. If your system uses Honeywell or Aprilaire filtration components, we handle those integrations too, ensuring sealed ducts work with your whole air quality setup.
Common Duct Sealing Problems We See in Cheshire Village Homes
- Original dirt-floor basements acting as contaminant reservoirs. In the oldest parts of Cheshire Village, stone or brick foundations with dirt floors release fine soil particles and moisture that get drawn into ductwork through leaky return plenums. Sealing returns without addressing these pathways is temporary at best.
- Unsealed crawlspace duct runs with rodent damage. Technicians frequently find supply ducts in unheated crawlspaces where mice and chipmunks have chewed flex duct for nesting material. We seal the access points and repair the damage, then seal the system properly.
- Retrofit HVAC creating incompatible connections. When forced air was added to a home built for coal or oil heat, installers sometimes used adapters that don’t form lasting seals. Metal-to-flex connections dry out and separate; we replace these with proper transition fittings and sealant.
- Basement humidity degrading tape seals. Cheshire’s damp summers and high water table mean standard duct tape fails within a few years in basement environments. We find homes where every joint was “sealed” a decade ago and none of it holds. We use mastic and mechanical fasteners rated for wet conditions.
Pricing for Duct Sealing in Cheshire Village, CT
Duct sealing in Cheshire Village runs $450 – $950 for a complete residential system. Here’s how that breaks down:
- Small home (under 1,500 sq ft), accessible basement mechanical room: $450 – $650
- Mid-size home (1,500 – 2,500 sq ft), some crawlspace or finished-area access: $650 – $850
- Large or complex home (2,500+ sq ft), multiple zones, attic or extensive crawlspace runs: $850 – $950
- Aerosol sealing add-on for inaccessible ductwork: $200 – $400 additional
- Duct insulation wrapping, per linear foot: $8 – $14
What moves you within these ranges? Accessibility is the big one. A home with an unfinished basement and exposed ductwork is straightforward. A colonial with ducts running through a tight, stone-walled chase to the second floor takes longer. The condition of existing seals matters too; if we’re removing failed tape and cleaning old mastic before resealing, that adds labor.
