Damp air is the defining housekeeping problem here. This guide draws on LSU AgCenter advice to explain what helps, what cleaning can handle and when you need a contractor instead.
If you have lived here for a while, you already know the signs: a musty closet, a shower that never quite dries, shoes that grow spots if left in a dark corner. A dry-climate transplant may need a season or two to catch on.
This guide covers what causes that, and what to do about it. TotalCare Cleaning does not treat mold or repair water damage, so some of the steps below are for a contractor. Everyday surface cleaning is the part a house cleaner can help with.
Baton Rouge averages about 62 inches of rain a year and 77 days with at least a tenth of an inch. About 96 days a year reach 90 degrees or hotter, and only about 18 nights reach freezing. Warm, wet air stays around for most of the year.
The LSU AgCenter warns that humid air, damp items and wet ground under a home can lead to mold, dust mites and bacteria growing inside. Homes that have flooded have an extra reason to pay attention: the most widespread 2016 flooding hit East Baton Rouge, Livingston, Ascension and Tangipahoa parishes, so a persistent smell in a repaired home is worth checking.
About 58 percent of homes in the city were built before 1980, so ventilation may be older too, though that varies from house to house.
The AgCenter's advice starts with the source. Cleaning a damp surface without fixing why it is damp only buys time.
Regular cleaning removes the soap film, skin oils and dust that give mildew something to live on. Wiping shower walls, washing bath mats and clearing dust from window tracks all help. A Recurring House Clean keeps those surfaces under control, and a One-Time Deep Clean gets into the tracks, blinds, vents and baseboards in one visit.
Cleaning cannot deal with mold growing inside a wall, on drywall or beneath flooring. Spreading growth, a patch that returns within days, soft drywall or a smell that does not fade are all signs of a problem beyond surface cleaning. Have a qualified contractor check it. TotalCare Cleaning's visit comes after that work is finished.
Humidity also feeds dust mites, which is why the AgCenter's allergy advice focuses on routine. It recommends mopping and wiping away dust, using a HEPA vacuum, and washing bedsheets in hot water every two weeks. The Asthma and Allergy Foundation's 2026 report placed Baton Rouge 69th among the 100 metro areas it scored, though any one household's experience can differ. If symptoms are troubling, a doctor is the right person to ask.
Bathrooms. Run the fan during showers and for a while after, and leave the door open when you finish. Squeegee the glass. The water is soft here, with total hardness no more than 52 milligrams per liter on the Baton Rouge Water Company system, so what you see on glass is often soap film.
Closets. Leave a little space between hanging clothes, and wash anything that smells musty. Keep shoes and bags dry before putting them away.
Kitchens. Use the range hood while cooking. Check under the sink every so often for slow drips. Wipe the rubber door seal on the refrigerator, and empty the drip pan.
Entries. Use washable mats, and dry them fully. Rain falls on 77 days a year, so these need attention more than most other parts of a home.
