Spring in Connecticut means thawing snow, April rain and windows opening after a closed winter. It also means moisture, and moisture is the whole condition mold needs. If the house has been holding water anywhere it should not, this is the season it shows. Here is where to look, what to do, and how to stop it before it becomes an expensive job. Have you looked behind the boxes and into the corners you only open in spring?
Why spring is mold's favourite season
Humidity rises. Warmer air holds more moisture, and the house ends up damp in the places it was dry in January. Snowmelt. Water from melting snow and ice finds cracks in the foundation, leaky windows and poor drainage, and comes in. Spring rain. Gutters, roofs and windows that were not maintained let April showers into the structure. Condensation. Warm days and cold nights mean water condenses on windows, walls and pipes, in pockets where mold takes hold.
Where it grows
Basements and crawl spaces. High humidity and poor ventilation, plus snowmelt seeping in, make them ideal. Attics. Leaky roofs, poor ventilation and condensation trapped under the roof deck. Bathrooms. Steam from showers, especially where the extractor fan is not working or not used. Behind walls and under floors. Hidden moisture from leaks and condensation, which is why inspection matters: you cannot see this one. Windowsills. Condensation in older, poorly insulated windows sits right on the frame.
1. Control indoor humidity
Dehumidifiers in damp areas such as basements and crawl spaces. Exhaust fans in bathrooms, kitchens and laundry rooms, running long enough to clear the moisture rather than for the length of the shower. Open windows when the weather allows, and use air conditioning in the warmer months to pull moisture out of the air.
2. Find leaks and fix them
Roof: missing or damaged shingles let water into the attic. Windows and doors: check the seals for cracks and gaps. Plumbing: under sinks, around toilets, along pipes. A slow drip is enough to keep a patch of mold alive. Foundation: water should not pool at the base of the house. Clean the gutters and make sure downspouts carry water away from the foundation rather than along it.
3. Ventilate properly
Exhaust fans in the bathroom, kitchen and laundry should vent outside, not into the attic. Check the attic vents and fans so moisture is not trapped under the roof. Open windows whenever the weather permits.
4. Clear the gutters early
Clogged gutters back up, leak and feed mold. Clean them in early spring, once the snow has gone, and confirm the downspouts run free and away from the house rather than along the foundation. While you are up there, look at the flashing and the roof edge for lifted shingles: the leak that wets an attic in April is the one that feeds growth you will not spot until summer, by which point it has had two months of damp to work with.
5. Use mold-resistant materials where it is wet
Mold-resistant drywall in the rooms prone to moisture, mold-resistant paint in bathrooms and kitchens, and waterproof flooring such as vinyl or ceramic tile in basements and bathrooms so water cannot reach the subfloor.
6. Dry what comes in wet
Snow boots, wet coats, the boot tray and the mat by the back door: anything that comes in wet in March and stays wet for a week gives growth a corner to start in where nobody looks. The same goes for condensation running down basement walls during a thaw. Dry it, give the room air, and the season passes without anything taking hold.
If you find mold anyway
Contain the area first so spores do not travel through the house. Small patches can be cleaned with a commercial mold cleaner or water and vinegar, wearing gloves, a mask and goggles. Bigger growth, or anything behind a wall, belongs to a professional remediation company. Disturbing it yourself spreads it.
