Regular Maintenance and Repair

Following these simple suggestions can prevent many problems associated with excess moisture:

  1. Keep obstructions in valleys such as leaves cleaned off to prevent water backup under shingles.
  2. Keep gutters clean and in good repair.
  3. Keep flashings sealed around fireplace chimney and all pipes/vents that extrude through the roof.
  4. Repair plumbing, fixture and appliance leaks immediately.
  5. Check in the attic for leaks during heavy rains.
  6. Have the fireplace checked and cleaned annually.
  7. Be alert for dampness in areas such as under sinks, in bathrooms and in ceilings below bathrooms or other plumbing.
  8. If you need to wash the wood trim or siding, do not use a high pressure nozzle. The pressure could force water into the wall system through cracks, crevices, faulty caulking, etc.
  9. During the air conditioning season, pour 1/2 cup bleach down the condensate drain to prevent algae growth, which could then cause a plugged drain.
