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 Air Duct Cleaning Across Old Greenwich
Air duct cleaning in Old Greenwich typically costs between $450 and $950 for a full system on a standard single-family home, with most jobs completed in four to seven hours. Homes with crawl-space ductwork near Shore Road or Greenwich Cove often land at the higher end because of moisture-related buildup that takes longer to remove properly. We serve the entire village, from Sound Beach Avenue to the shoreline streets, and you can reach us at (980) 447-2498 any time. A live person answers, not an automated system.
What separates duct work in Old Greenwich from work in Stamford or Riverside is the marine layer. The same salt-laden humidity that corrodes outdoor hardware gets pulled into return ducts and settles inside supply runs. It makes cleaning here different. Not harder in a dramatic way, but different enough that a crew running an inland playbook will miss things. We don’t.
Why Linden Air Duct Cleaning Is Old Greenwich’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Old Greenwich on a simple standard: every technician who walks through your door is background-checked, identity-verified, and introduced to you by name and photo before the visit. That’s the Threshold Standard, and it applies to every job we do, from a small dryer vent cleaning to a full-system duct cleaning after a crawl-space flood. When the tech arrives, they show a photo ID badge at the door. Every time. No exceptions.
Marcus Veale leads our team, and he holds us to the 365-Day Done Right Promise: if the work is not right, we make it right, in writing, on every job. That promise matters in Old Greenwich because coastal duct systems fail differently than inland ones. A crew that underbids a Greenwich Cove job usually skips the camera inspection and the moisture verification. We don’t, and our guarantee backs that up.
We coordinate scheduling from our Hartford office, but our crews work locally in Old Greenwich. That means you get a team that knows the village’s housing stock, not a dispatcher routing a truck from across the county.
Ductwork Cleaning in Old Greenwich
Ductwork cleaning in Old Greenwich homes involves running a negative-pressure extraction system through the full supply and return network while agitating the duct walls to break loose accumulated debris. In pre-1960s colonials and cape cods around Oval Avenue and Sound Beach Avenue, that debris is rarely just dust. We pull out salt-particulate deposits, crawl-space moisture residue, and biological growth that forms in the narrow-gauge ductwork common to this housing stock. A standard full-system cleaning on a 2,500-square-foot home here runs $500 to $850, depending on the number of returns and the condition of the crawl space.
Supply and Return Duct Servicing
Supply ducts in Old Greenwich homes carry conditioned air through spaces that often run alongside vented crawl spaces. When moisture wicks from the crawl into the duct interior, supply-boot connections become mold colonization points. We clean those connections with agitation tools rather than just vacuuming past them.
Return ducts pull air from the home back to the air handler, and in coastal properties they also pull in whatever humidity is present in the living space. That’s why return-side buildup here is stickier and more biologically active than what you’d find in Cos Cob or Backcountry. Our procedure treats return ducts as a separate cleaning zone, not an afterthought.
Full System Cleaning With Verification
After cleaning, we run a camera through representative sections of the system to verify what the extraction actually removed. On jobs where moisture has been present in the crawl space, we take moisture readings at supply boots and flex-duct junctions. If a section can’t be dried back to specification, we document it with photos and readings so you have evidence for an insurance claim. That’s the difference between cleaning ductwork and documenting a problem.
Air Duct Inspection in Old Greenwich
Air duct inspection in Old Greenwich means sending a camera through the supply and return runs, with particular attention to the crawl-space-routed sections that dominate this village’s pre-1960s housing stock. We’re looking for mold colonization at boots, standing moisture in flex duct, corrosion at metal connections, and salt-particulate buildup. A standalone inspection with a written report runs $150 to $250 and takes about an hour for a standard home. When we’re already on site for cleaning, we include inspection as part of the job and document everything with before-and-after photos.
Post-Storm and Post-Flood Duct Assessment
When a storm pushes water into a vented crawl space off Shore Road or near Greenwich Cove, the duct system becomes a quiet liability. Water that gets into flex duct or saturates the insulation at supply-boot connections creates conditions for mold within days, not weeks. We inspect first, then tell you honestly which runs can be cleaned and which need replacement. That order matters. Cleaning a saturated duct without verifying the crawl space is dry just means the mold returns in a few weeks.
Insurance-Ready Documentation
If your ductwork has failed after water intrusion, an insurer will ask for proof that cleaning alone is not enough. We provide that proof: camera footage, moisture readings, and labeled photos showing exactly where the system failed and why. Homeowners who have that documentation get replacement covered far more often than those who submit a cleaning invoice and hope for the best. We’ve watched it work enough times to know that evidence changes the conversation.
Trusted Brands We Service in Old Greenwich
We run professional-grade equipment from Rotobrush and Nikro, and we work with air-quality components from Abatement Technologies and Guardsman when remediation or filtration upgrades are warranted. For Old Greenwich customers, that means the equipment showing up at your door is the same class of gear used on commercial and hospital-grade jobs, not a rental from a big-box store. If you need Old Greenwich Air Duct Repair, we keep common components in stock so a repair or replacement part doesn’t mean a two-week wait.

Common Air Duct Cleaning Problems We See in Old Greenwich Homes
- Mold colonization at supply-boot connections. Crawl-space moisture wicks into duct interiors year-round here, not just in summer. Within two to three years of a prior cleaning, the boots can show active growth again.
- Salt-particulate accumulation inside return ducts. The marine layer off Long Island Sound deposits fine salt particles that get pulled into the return side. This buildup accelerates corrosion at metal joints and makes standard vacuuming insufficient.
- Saturated flex duct after storm events. Low-lying streets off Shore Road and around Greenwich Cove are vulnerable to crawl-space flooding. Flex duct that sits in or above that moisture needs replacement far more often than crews from inland areas expect.
- Narrow-gauge ductwork that was never designed for modern airflow. Pre-1960s colonials and cape cods often have undersized, partially uninsulated ducts. Debris builds faster, and cleaning takes longer than on newer construction in nearby Stamford.

FAQs About Air Duct Cleaning in Old Greenwich
The answer depends on what a camera inspection and moisture readings show. Flex duct that has absorbed water into its insulation layer cannot be cleaned back to a safe condition and should be replaced. Metal ductwork that got wet but dried quickly can usually be cleaned with HEPA filtration and negative pressure. We inspect first, then give you a straight answer with documentation. If replacement is needed, we give you the evidence your insurer will ask for. Call (980) 447-2498 to schedule an assessment.
The marine layer off Long Island Sound keeps indoor relative humidity elevated through all four seasons, not just summer. Combined with the vented crawl spaces common under pre-1960s homes, that humidity wicks into duct interiors year-round. Homes even five miles inland in Cos Cob don’t see the same persistent moisture load, which means their ducts dry out between humid periods. Ours don’t.
We document everything: camera footage through the affected runs, moisture readings at supply boots and flex junctions, and labeled before-and-after photos. When an adjuster can see standing moisture and mold colonization inside a duct, the claim shifts from “cleaning” to “replacement” quickly. Homeowners with documentation get covered. Those without it usually don’t. That’s the honest answer.
Yes. Every full-system cleaning in Old Greenwich runs under negative pressure with HEPA-filtered air, so what we remove from the ducts stays contained and does not recirculate through your living space. On coastal homes with crawl-space-routed systems, we also verify the crawl space is dry before cleaning. If it’s not, cleaning is premature.
We run Rotobrush and Nikro cleaning equipment and use air-quality components from Abatement Technologies and Guardsman when filtration or remediation is required. These are trade-grade brands, not consumer fixtures, and they’re the right tools for the salt, moisture, and biological buildup specific to Old Greenwich duct systems. If a component needs replacing, we’ll tell you what it is, why it failed, and what it costs before any work starts.
