Gatewood, King County
Duct cleaning for a Gatewood house starts at $535. That opening price fits a modest single-story layout with one furnace and a normal count of supply and return registers. More floors, more runs, a second system, or ductwork buried in tight crawlspaces add hours, and the quote counts the registers so you can see where the time goes. The work itself is straightforward: put the whole system under negative pressure with a powerful collector, loosen what clings to the inside of each duct, and pull it out rather than blow it around the house.

How a Gatewood house is heated decides whether this service applies at all. For the Census ZIP code area around Gatewood, the 2020 to 2024 estimates split occupied homes roughly in half between electric heat and everything else: utility gas 41.9 percent, fuel oil 4.7 percent. A gas or oil furnace usually sends its heat through ducts, though a boiler feeding radiators does not. Electric heat may or may not: a heat pump uses ducts, wall and baseboard heaters do not. If your home has no supply registers in the floor or walls, you do not need us for this.
Gatewood School's enrollment, HistoryLink records, jumped to 768 in April 1943 with the opening of the High Point housing project and passed 800 again in the 1950s. Houses from those surges have had seventy years to change their heating. Some of them, the heating-fuel figures above suggest, may still be on oil today.
A furnace may have been replaced two or three times while its ducts stayed in place. Where oil was burned for decades, it is worth looking for soot in the supply trunk near the furnace before assuming the ducts only hold household dust. We put a camera into a few branches during the estimate, show you what is there, and tell you plainly if the system does not need cleaning yet.
Every air duct cleaning we do in Gatewood includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowWhatever a household sheds ends up in its ducts: lint and skin flakes, the dog's undercoat, drywall powder from the last renovation, occasionally old soot. Winter adds wood smoke from the neighborhood. The Clean Air Agency's 2024 summary counts up to four winter days in 2024 on which wood smoke alone carried fine particles over the agency's health target. A system recirculating air all winter may draw some of that in. For smoke episodes, the agency advises HEPA filtration or a box fan fitted with a MERV-13 or better filter; we can suggest a furnace filter grade your blower can handle.
We walk the house, count registers, find the furnace and trunk lines, and confirm the price before starting.
Every register gets taped over; then the collector hose is cut into the trunk line, and the ducts start pulling air toward it.
Air whips or brushes go into every supply and return, one at a time, loosening dust toward the collector.
Grilles and registers are washed; the blower compartment is vacuumed and wiped where it can be opened safely.
Access holes are sealed, the system is restarted, and we check airflow at a few registers before leaving.

From $535 for a small single-system house. Larger homes and multiple systems cost more; the quote is built from the register count.
Cleaning removes what has settled. During smoke episodes, filtration does the daily work; the Clean Air Agency points to HEPA units, or a box fan wearing a MERV-13-plus furnace filter.
No. A house with no ducts gives us nothing to clean. A bathroom or kitchen exhaust fan is a different, smaller job.
We can schedule both. The chimney visit runs $99 plus tax for each flue stack, and that sum is credited toward chimney work you approve.
