Are you and your Community’s homeowners prepared for the spring rainy season? Heavy spring rains and spring thaw greatly increase the risk of water intrusion and mold problems.

Water can enter the building envelope and foster the growth of mold in several different ways.  But, with regular preventive inspection and maintenance, the risk of major problems can be reduced.  The following list should help you prevent small problems from becoming large (and expensive!).

SPRING/SUMMER WATER INTRUSION/MOLD CHECKLIST:

Exterior:

• Check gutters for debris. Confirm that downspouts are fully connected and splash block drain away from the building.
• Fill in settlement of backfill soil along foundations and make sure ground is graded away from the building to maintain proper drainage.
• Check and repair caulking around windows and doors.
• Inspect exterior facades and foundations for cracks, spaces or discolorations that might indicate water penetration.
• Make sure weep holes in window troughs and in brick facades are clear of any dirt or obstruction.

Interior:

• Verify sump pump operation. Keep drainage channels and discharge points free of debris and obstructions.
• Turn humidifiers off, shut off water supply and clean and dry interior of units.
• Check and operate air conditioning system, including condensation drains and pump for leaks or accumulated water.
• Inspect interior foundation walls for evidence of water stains or “efflorescence” (mineral deposits indicating chronic water penetration).
• Check crawlspaces for standing water (pump out immediately), and make sure air vents are unobstructed to allow air flow and protected against rain and debris entering.
• Consider installing vent fans with humidistat control in crawlspaces to maintain relative humidity below 60% during hot and humid months.

Important Reminders to Homeowners/Tenants:

• Periodically inspect for signs of interior water leaks, with special attention to attics, basements and plumbing fixtures.  Areas around and behind tile showers are at high risk for leaks and related damage.  Respond immediately to leaks to prevent mold and related damage.
• Change HVAC filters (quarterly) and look for signs of standing water in and around the furnace.
• Maintain indoor relative humidity levels at or below 55%, especially during hot and humid months.  Encourage homeowners to operate dehumidifiers in basements during the summer.
• Do not store basement contents on the floor or directly against foundation walls.  Long term stored items should be in sealed durable plastic tubs rather than cardboard boxes.
• Open windows or use vent fans in bathrooms during, and for 30 minutes after showers or baths to reduce humidity levels and the risk for mold.

Despite the best preventive efforts, water intrusion related damage and mold can happen.  How you respond can make the difference between a small event and a major case involving health claims, expensive repairs or reconstruction, regulatory enforcement and possible litigation.  Contact GSE for professional advice and assistance in this often emotional issue.
