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 Martha Lake’s Preferred Air Duct Cleaning Company
We’ve been serving Puget Sound homeowners since 2004 as part of the Garrison Partners family, and our Martha Lake customers know we don’t treat their homes like every other job. Our technicians follow The Garrison Standard: arrive inside the quoted window, price the work in writing before touching equipment, and leave the site clean. That discipline matters especially here, where the lake-effect moisture and 1960s-era duct systems require more than a standard blow-and-go.

When you schedule Air Duct Cleaning with Hollis, you’re talking to a real person who can confirm your appointment, explain what the technician will do, and email you the written estimate before we dispatch. Our crews are background-checked, uniformed, and equipped with professional-grade tools from Rotobrush and Nikro, not hardware-store attachments.

Air Duct Cleaning Services in Martha Lake
Air Duct Cleaning Services in Martha Lake mean source removal of dust, debris, and microbial growth from your entire duct network, not just the vents you can see. We serve homeowners from the original lakeside cottages near the boat launch to the expanded ramblers along 164th Street Southwest and the split-levels tucked behind Martha Lake Airport Park. A typical residential full-system clean in Martha Lake runs $350 – $650 depending on system size, accessibility, and whether we find conditions like rodent nesting or moisture damage that need additional attention.
Most Martha Lake homeowners schedule duct cleaning when they notice musty odors, reduced airflow, or visible debris at registers. The damp marine climate here means mold and mildew develop faster than in drier inland areas, so we often recommend cleaning every 3 – 5 years rather than the 5 – 7 year interval that might suffice east of the Cascades.
Residential Duct Cleaning
Our residential work covers single-family homes, townhouses, and duplexes throughout Martha Lake. We use rotary brush systems to agitate debris from duct walls, then extract it with HEPA-filtered negative-air machines. Every job includes a video inspection so you see what we found and what we removed.

Commercial Duct Cleaning
Small commercial buildings and multi-unit properties near Martha Lake’s retail corridors need scheduled maintenance to maintain indoor air quality and comply with insurance requirements. We coordinate with property managers to minimize tenant disruption and provide documentation of work completed.

HVAC Duct Cleaning in Martha Lake
HVAC Duct Cleaning in Martha Lake addresses the complete heating, ventilation, and air conditioning pathway, from return grilles through the air handler to supply registers. In this market, the job frequently involves more than standard cleaning because original 1960s – 1980s metal trunk systems were never designed for the additions and conversions that followed. We find DIY duct runs in expanded ramblers that create pressure imbalances, drawing damp crawl space air into the system and distributing musty odors throughout the house. A typical HVAC duct cleaning in Martha Lake runs $400 – $750 for systems with these accessibility challenges.
Our process starts with a visual and camera inspection of the full network. We identify leaks, disconnections, and moisture intrusion points that a basic cleaning would miss. Then we source-remove debris using appropriate methods for rigid metal, flex duct, or duct board, and rebalance the system so supply and return pressures match the home’s current layout.
Supply Duct Cleaning
Supply ducts push conditioned air to your rooms. In Martha Lake’s older homes, these lines often terminate in additions with smaller diameter flex duct that reduces airflow and traps debris. We clean and inspect each branch, measuring static pressure to confirm the system performs after we’re done.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in Martha Lake, these are where we most often find problems. The fall rain season drives rodents into crawl spaces, and their nesting material ends up in returns along with degraded insulation. We extract this debris completely, then seal access points to prevent recurrence.
Trusted Brands We Service in Martha Lake
We carry professional-grade equipment and filtration products from Nikro, Honeywell, and Aprilaire, the same brands commercial crews specify. For Martha Lake homes with original systems lacking modern filtration, we stock Aprilaire media filters and Honeywell electronic air cleaners that install directly into existing return plenums. Our technicians arrive with the right tools for rigid-metal trunk systems, flex duct conversions, and mixed-era installations, so we don’t waste your time running for parts. If your system needs a component we don’t stock, our Seattle office coordinates next-day delivery for most items.
Common Air Duct Cleaning Problems We See in Martha Lake Homes
- Moisture damage in lake-effect crawl spaces. Duct runs near Martha Lake pass through spaces that stay damp year-round, promoting mold growth on metal surfaces and degrading flex duct insulation. A standard cleaning that doesn’t address the moisture source means mold returns within months.
- Rodent nesting in returns after fall rains. The wet season drives pests into crawl spaces, and they build nests in warm return ducts. We pull shredded insulation, droppings, and food debris from these lines regularly between October and January.
- Pressure imbalances from mismatched additions. Expanded ramblers often have original rigid-metal trunks feeding newer flex branches sized by whoever did the addition. The result is weak airflow to new rooms and backdrafting that pulls crawl space air into the system.
- Failed “sanitiser” fogging treatments. Previous companies sold chemical fogging that coated duct walls but left actual debris in place. Homeowners still smelled musty because the source, rodent nesting and wet insulation, was never removed.

FAQs About Air Duct Cleaning in Martha Lake
The musty smell usually means the previous cleaning left debris in place or missed a moisture source. In Martha Lake, lake-effect crawl spaces keep duct runs damp year-round, and mold grows on metal surfaces that a basic blow-and-go won’t address. We camera-inspect the full system, source-remove debris with agitation and negative pressure, and identify where moisture enters. Call (361) 326-5060 for an inspection and written estimate.
No. Fogging coats duct surfaces with a chemical that may temporarily mask odor but does not remove the physical debris causing it. We were called to a 1965 split-level near the Martha Lake boat launch where the homeowners complained of a musty smell every time the furnace kicked on. The original rigid-metal trunk-and-branch system ran through a crawl space that had clearly been wet for months – our tech used a camera inspection and agitation tools to find rodent nesting at the return, then pulled negative pressure with a HEPA-filtered unit and source-removed the debris before rebalancing supply and return ducts. We replaced the missing filter with an Aprilaire MERV 11 and showed the homeowner that the blower motor was pulling twice the debris it should – the fogging ‘sanitiser’ the previous company sold them had done nothing for the actual source.
Yes, and we specifically address the mismatched sections that standard kits miss. Original 1960s – 80s trunk-and-branch systems in Martha Lake were often expanded with flex duct runs that create pressure imbalances and trap debris. We inspect and clean every branch, measure static pressure, and rebalance the system so all rooms receive proper airflow. Call (361) 326-5060 to schedule.
Schedule an inspection promptly. The debris is likely rodent nesting material and degraded insulation that has been pulled into your return duct from a damp crawl space. This is common in Martha Lake’s lakefront and near-lake homes after the wet season begins. We extract the debris, inspect for entry points, and can recommend sealing solutions to prevent recurrence. Call (361) 326-5060 – estimates are free.
Every 3 – 5 years for most Martha Lake homes, sooner if you notice musty odors, visible debris, or reduced airflow. The high humidity and lake-effect moisture accelerate microbial growth compared to drier climates, and older systems with crawl space runs need more frequent attention. Homes with additions and mismatched ductwork may need inspection every 2 – 3 years to catch pressure problems before they degrade air quality. Call (361) 326-5060 to discuss your system’s condition.
