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.

Why Hollis Air Duct Cleaning Is Cape St. Claire’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our reputation in Cape St. Claire is built on showing up when we say we will and leaving the price where we wrote it. Our technicians know the local housing stock, the 1960s-era ranches near the water, the split-levels off College Parkway, and the newer construction closer to the community entrance. That matters because a duct system in a 1972 Cape St. Claire ranch with original galvanized steel behaves differently than flex duct in a 2005 build.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When you schedule with Hollis, you get a written price before any work starts and a 365-Day Done Right Promise that covers every repair in writing. If something fails within a year, we return and make it right at no charge, including a free second visit. Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the window, price in writing, complete the job by the book, leave the site clean.
Air Duct Inspection in Cape St. Claire
Air Duct Inspection in Cape St. Claire starts with a video camera fed through your supply and return lines to document what we’re dealing with before we quote a dollar. Most Cape St. Claire homeowners need this when they notice persistent musty smells, visible dust plumes from registers, or rooms that won’t hold temperature. Given the bay humidity and older ductwork common here, we often find corrosion, mold colonization, or disconnected flex runs in crawl spaces and attics. A standalone inspection runs $150 – $250 in the Cape St. Claire market, and we apply that toward your cleaning if you move forward.
What We Document
Our inspection records debris load, microbial growth, duct integrity, and airflow restrictions. In Cape St. Claire, we pay special attention to salt-air corrosion on metal components and condensation points where humid outside air meets cooled duct surfaces.
When to Schedule
Book an inspection if your system is more than five years since its last cleaning, if you’ve recently renovated, or if anyone in your home has worsening allergy symptoms. The inspection itself takes 45 – 60 minutes and leaves no mess.
Residential Air Duct Cleaning in Cape St. Claire
Residential Air Duct Cleaning in Cape St. Claire means pulling built-up debris from your entire forced-air system using a rotary brush system and negative-air machine connected at the furnace. We clean supply ducts, return ducts, the blower compartment, and registers. Most Cape St. Claire homes need this every three to five years, though the coastal humidity here pushes some households toward the shorter end of that range. A full residential cleaning in Cape St. Claire typically runs $350 – $650 depending on system size, accessibility, and contamination level.
Our Process
We seal each register, agitate debris with a Rotobrush rotary system, and extract it with a Nikro negative-air machine so nothing migrates into your living space. For Cape St. Claire’s mold-prone climate, we offer antimicrobial treatment applied after cleaning.
What You Should Notice After
Stronger airflow at distant registers, less dust resettling on surfaces, and often a marked reduction in that bay-area mustiness that lingers in older Cape St. Claire homes. We take before-and-after photos of your own ducts so you can see the difference.
Trusted Brands We Service in Cape St. Claire
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use, not hardware-store gear. For Cape St. Claire homeowners, this means we can source replacement components and filtration media without long waits. If your system uses a Honeywell electronic air cleaner or an Aprilaire media cabinet, we stock the correct filters and can install them while we’re on site. We also handle Dryer Vent Cleaning in Cape St. Claire and Duct Sealing in Cape St. Claire using compatible professional-grade materials.
Common Air Duct Cleaning Problems We See in Cape St. Claire Homes
- Musty, fishy odors from bay humidity. The salt-laden air in Cape St. Claire penetrates poorly ventilated crawl spaces and attics, creating ideal conditions for mold and bacteria that produce a distinct odor homeowners often describe as “fishy” or “rotting wood.” We find this most often in homes near the waterline and in raised ranches with minimal foundation ventilation.
- Corroded galvanized steel ductwork. Many Cape St. Claire homes built between the 1960s and 1990s still run original galvanized supply lines. The combination of condensation and salt air accelerates rust, which weakens seams and creates air leaks that pull in crawl space air.
- Disconnected flex duct in attics. Summer attic temperatures in Cape St. Claire can exceed 140°F, degrading the adhesive on flex duct connectors. We regularly find fully separated runs blowing conditioned air into attics instead of bedrooms.
- Dust mite and allergen buildup from year-round humidity. Dust mites thrive above 50% relative humidity, and Cape St. Claire rarely drops below that threshold. Ducts become reservoirs for allergen-laden debris that recirculates every time the blower cycles.
