Chattanooga sits near the top of national lists for seasonal allergies. Here is where tree pollen collects inside a home and how to clean for it from March through May.
Each spring a yellow-green film coats cars, porches and patio tables across Chattanooga. Most of what you can see is pine, but it signals that the more allergenic trees are pollinating as well. The part that gets inside the house is the part a cleaning routine can do something about.
This guide covers the local pollen season, where pollen ends up indoors, and the routines that help during the worst weeks. It is about cleaning, not medical advice; an allergist is the right person for treatment.
The Asthma and Allergy Foundation of America ranked Chattanooga 16th of the 100 largest metro areas in its 2025 Allergy Capitals report. Local reporting points to Hamilton County's many trees, especially on the mountains, as the driver of early spring pollen, with April and May the hardest months and counts that can climb into the thousands.
A Chattanooga Allergy Clinic allergist told WDEF in March 2025 that trees were releasing pollen earlier and in larger amounts. She also noted that the pine pollen people notice is not the most allergenic; it simply shows that all the trees are pollinating at once.
Pollen does not stay where it lands. It rides in on clothes, hair and pets and then settles wherever air slows down. These are the spots to check first:
Chattanooga's spring is wet. March is the wettest month in the 1991 to 2020 normals, at about 5.3 inches, and the city averages 55 inches a year. Damp pollen clumps onto screens, sills and porch rails rather than blowing away, then dries and crumbles into fine dust that tracks inside.
That is why a damp cloth beats a dry duster here. Wiping lifts the clumps and the fine dust together; a feather duster sends both back into the air.
On the outdoor side, the Chattanooga-Hamilton County Air Pollution Control Bureau publishes a local air quality forecast, a useful daily check for planning yard work and deciding whether to air out the house. Indoors, these habits do the most:
For allergy households, the best time for a One-Time Deep Clean is after the heaviest weeks of tree pollen, often late May, so the hand washed baseboards, wet-wiped blinds, wiped fans, vents and light fixtures and vacuumed couch crevices stay clean longer. During the peak, a weekly Recurring House Clean that dusts reachable baseboards and blind slats each visit keeps the layer thin. The deep cleaning guide lists everything that visit covers.
If someone in the home is sensitive, ask any cleaning company whether it can use fragrance-free products and damp cloths instead of dry dusters.
Older houses give pollen more places to hide. About 29 percent of city homes were built before 1960, and many have wood windows with deep tracks and grooved trim that hold fine dust. Mountain towns get a double dose: Signal Mountain runs a spring leaf collection round in April, right in the middle of tree season, on top of its long fall leaf season. The older home guide covers gentle methods for original finishes.
