Remodeled ranches hide old problems

South of 38th Avenue, block after block of mid-century ranches have been updated: open kitchens, finished basements, new flooring. Remodels are good for the housing stock, but they can cover up earlier water damage. Drywall and laminate flooring laid over an old basement that once took on water can trap moisture against concrete and framing that never fully dried.

Lena Gulch, a drainage channel running through this part of the city, carries stormwater north toward Clear Creek. Most homes are not directly beside it, but heavy rain in the neighborhoods it drains can overwhelm street inlets, window wells and low driveways. Homes at the bottoms of local slopes see more of that runoff than those at the top.

Older ranch versus newer infill

Mid-century ranch

  • Basements often finished long after construction, sometimes without vapor control
  • Original clay sewer service lines under mature trees
  • Crawlspaces with partial or old ground cover
  • Older materials that may need asbestos testing before removal

Newer townhome or infill house

  • Tighter construction that holds indoor humidity if ventilation is weak
  • Bathroom and laundry upstairs, so leaks travel down through ceilings
  • Window wells and grading that may not be settled yet
  • Shared walls where a neighbor's leak can reach your unit

Where to start if you smell mold

  • IfYou own a remodeled ranch with a finished basementCheck the bottom of exterior basement walls behind trim and under carpet first.
  • IfYou live in a newer townhomeLook at ceilings below bathrooms and laundry, and run bath fans longer.
  • IfThe smell started after a big stormCheck window wells and the lowest corner of the basement nearest the street.
  • IfThe smell is near a floor drainRule out a dry trap or sewer gas before assuming mold.

Before buying a remodeled home here

  • Ask the seller about past basement water, even before the remodel
  • Check whether permits were pulled for the basement finish
  • Have the sewer line camera-inspected
  • Look for fresh paint or new trim limited to one basement wall
  • Take a moisture meter reading at the base of exterior walls

Common questions

Do newer townhomes get mold less often?
They avoid some older problems, but tight construction keeps moisture indoors if bath fans and ventilation are not used. Leaks from upstairs bathrooms and laundry also show up as ceiling stains below.
