July home maintenance checklist

• Make sure flood protection works before a storm DIY
  Check the backwater valve flap moves freely and test the sump pump. If your pump has a battery backup, check the battery's age and charge. Waterproofing cost guide →
• Keep the AC running efficiently DIY
  Change the filter if it's dirty and rinse dust off the outdoor coil with a garden hose (power off first). Setting the thermostat very low doesn't cool the house faster.
• Clean out window wells DIY
  Remove leaves and garbage from basement window wells and check the drain at the bottom isn't blocked. A clear cover keeps them dry.
• Re-caulk tubs and showers DIY
  Look for cracked or mouldy caulking around tubs, showers and sinks. Water that gets behind tile causes far more damage than the caulking costs. Bathroom renovation guide →
• Check for wasp and ant nests DIY or pro
  Look under eaves, deck boards and around the foundation. Carpenter ants near damp wood can point to a leak.
• Check the pool gate DIY
  Pool gates must close and latch on their own. Test that it swings shut and latches from any open position. Pool repair guide →
