Window wells without drainage

Wells that fill with water leak around frames and can saturate walls.

Weak bathroom ventilation

Older bathrooms with disconnected or noisy fans hold steam and grow mold on ceilings.

Seasonal mold risk near Columbine Knolls South

Winter

Ice dams on shaded roofs, burst pipes in older exterior walls and condensation in tightly closed rooms.

Spring

Heavy wet snow, rapid melt and rising groundwater near lakes and creeks stress basements, crawl spaces and sump pumps.

Summer

Foothill thunderstorms and hail, swamp-cooler humidity and clogged AC condensate lines.

Fall

Tree leaves clog gutters and downspouts, and sprinkler blowout mistakes leave water against foundations.

How to prevent mold in Columbine Knolls South

These steps fit the conditions in this part of town:

  • Keep sump pumps tested and consider a battery backup, especially near lakes and creeks.
  • Seal and ventilate crawl spaces, and add a vapor barrier over bare soil.
  • Check the grade around the house: soil should slope away from the foundation for several feet.
  • Inspect shaded roof sections and gutters before winter to reduce ice dams.
  • Replace aging galvanized supply lines and old drain connections before they leak inside walls.
  • Run a dehumidifier in tri-level lower rooms and monitor humidity with a hygrometer.
