Follow these good maintenance practices and inspect your new home on a regular basis to avoid problems.


  • Check smoke and carbon monoxide detectors to ensure they are working. Replace batteries in battery-powered units.
  • Clean or replace filters in HRV, furnace, hoodfan, etc. (do monthly or as needed)
  • Turn off and clean humidifier and close humidifier damper, if you have a humidifier.
  • Ensure air conditioner is ready for use. Close air supply vents to basement to direct cooler air to upper levels of house.
  • Adjust thermostat to summer mode, if you have an air conditioner. Set temperature to 23°C or warmer when heat is no longer needed.
  • Keep furnace fan on if you do not have an air conditioner (set temperature to 15°C to keep it from heating during the summer). Run the fan at all times to provide ventilation to the house.
  • Use a dehumidifier in basement (connect directly to drain) to remove excess moisture from new construction materials.
  • Ensure indoor air vents (HRV & forced air furnace supplies & returns) are clean and not blocked by dust, furnishings, drapes, etc.
  • Turn off pilot light for gas fireplace and clean glazing. Follow instructions in fireplace manual.
  • Know your plumbing. Learn how to shut off the water and where your pipes are located. Inspect for any signs of plumbing problems.
  • Clean windows, screens and hardware. Ensure windows operate smoothly.
  • Vacuum rear of refrigerator and freezer to improve operating efficiency. Clean drip pans.
  • Ensure sump pump (if you have one) is ready to operate when needed. Make sure discharge pipe is connected and directs water away from foundation.
  • Lubricate garage overhead door track, rollers and hinges. Inspect to ensure operating correctly.


  • Check exterior surfaces of home (including roof and flashings) for items damaged or loosened by winter weather or animals; repair as needed.
  • Clear debris from swales, drainage ditches and culverts; ensure melting snow can run off property.
  • Clean winter debris from eavestrough. Check that eavestrough and downspout joints are secure and ensure water flows away from foundation (at least one metre).
  • Ensure roof louvers, vents and soffits are not blocked. Ventilation is a critical factor in roof durability – air must be able to move through the attic. Check for damaged areas, nests, trees or vines blocking openings, etc.
  • Inspect exterior fixtures, such as lights and satellite dishes, to ensure securely anchored.
  • Ensure gas meter is not blocked by debris, vegetation, snow, etc.
  • Remove any debris from window wells.
  • Check for ground settling at foundation. You may need to build up landscaping to ensure rainwater flows away from your foundation wall.
  • Check exterior steps and readjust, if settled or unstable.
  • Ensure outdoor air vents (exhausts, intakes, dryer, HRV, forced air furnace) are not blocked by debris, vegetation, snow, etc.
  • Remove winter cover from outside air conditioning unit and clean debris from coils.
  • Close bleeder nut and open valve to outside hose connection (hose bib) after danger of last frost.
  • Fertilize young trees and begin spring landscape maintenance.
  • Remove protective shrouds from delicate plants and shrubs.
  • Apply lawn seed to bare patches.
