Kent's mixed housing stock adds a wrinkle most duct-cleaning companies skip over: homes built before 1980, common near the original townsite and West Hill, sometimes have asbestos-containing duct wrap or transite duct board. Washington State L&I and Department of Ecology rules govern how contractors identify and handle that material during a cleaning job. If your project involves sealing, resizing, or reconnecting ductwork rather than a straight cleaning, the City of Kent may also require a mechanical permit under the state-adopted mechanical code.
Local knowledge
What's different about duct cleaning in Kent
Local housing stock and utilities in Kent change what this work involves.
Homes in the Green River valley and lower Kent neighborhoods often route ductwork through crawlspaces with higher moisture levels, which speeds up mold and mildew buildup compared to hillside homes on East Hill or West Hill.
PSE supplies both gas and electric service through most of Kent, and gas forced-air furnaces common in the city's older subdivisions push more dust and combustion byproducts through the duct system over time.
Newer construction on East Hill and around Lake Meridian built since the 1990s still has drywall dust and framing debris settle into duct runs during the first few years, even in homes that look new.

How a Kent duct cleaning visit works
1
Inspection and permit check
We inspect duct material and condition first, note the home's approximate build year, and flag whether the scope of work (cleaning only versus sealing or resizing) requires a City of Kent mechanical permit.
2
Protect and isolate the system
Registers, furniture, and flooring near vents are covered, and the system is sealed off from the rest of the home before any equipment runs.
3
Negative-pressure cleaning
A HEPA-filtered vacuum unit creates negative pressure inside the ductwork while agitation tools dislodge dust, pet hair, and debris from supply and return runs.
4
Sanitizing or deodorizing (if needed)
For homes with pet odor, smoke residue, or musty crawlspace ducts, we apply an EPA-registered sanitizer as an optional add-on before the system is closed back up.
5
Final walkthrough and documentation
We show before-and-after debris collected, confirm all registers are reset, and provide documentation of any permit filed for the job.

Straight answers
Duct Cleaning in Kent — FAQ
Do I need a permit for duct cleaning in Kent?
Straight cleaning of existing ductwork usually does not require a permit. Under the state-adopted mechanical code that the City of Kent enforces, work like resizing ducts, sealing with mastic, or reconnecting sections typically does need one. We tell you upfront if your job crosses that line before we start.
My Kent home was built in the 1970s. Could the ducts contain asbestos?
Homes built before 1980 in older Kent neighborhoods, including areas near the original townsite and West Hill, sometimes used asbestos-wrapped duct insulation or transite duct board. WA L&I and Ecology rules require specific identification steps before cleaning, so we inspect first and stop work on any suspect material rather than disturbing it.
How long does whole-home duct cleaning take in a typical Kent house?
Most single-family homes in Kent, including split-levels common on East Hill, take 2 to 4 hours depending on duct length and the number of return vents. Larger homes near Lake Meridian or with finished basements can run longer.
Do you serve areas outside Kent proper, like the East Hill or Covington border?
Yes, we cover all of Kent including East Hill and neighborhoods near the Covington line, along with Seattle, Bellevue, Redmond, Kirkland, and Sammamish, dispatching from our Seattle base.
