Owning a home is one of the biggest investments you’ll ever make — and like any investment, it needs consistent care.
Most homeowners remember the obvious tasks: mowing the lawn, cleaning the gutters, shoveling the driveway. But it’s the small, overlooked maintenance items that often lead to costly repairs — foundation cracks, water damage, mold issues, or premature appliance failure.
In Ontario especially, where we deal with freeze-thaw cycles, heavy rain, humidity, and hard water, preventative maintenance isn’t optional — it’s essential.
Here are 10 commonly forgotten home maintenance tasks that protect your home’s value, improve efficiency, and prevent expensive surprises.

Bathroom fans remove moisture from showers and baths. When they’re clogged with dust, they can’t do their job properly — which leads to excess humidity, peeling paint, and even mold.
How often? Every 6 months
Why it matters in Ontario: Humid summers + tightly sealed winter homes = trapped moisture.
Remove the cover and vacuum the fan housing to keep air flowing properly.

Southern Ontario is known for hard water. Over time, sediment builds up at the bottom of your hot water tank, reducing efficiency and shortening its lifespan.
How often? Once per year
Benefits:
Improves energy efficiency
Extends tank life
Reduces noise
Helps lower utility costs
This simple task can add years to your water heater.

Rubber washing machine hoses are one of the most common causes of interior flooding.
They crack and bulge quietly — and often burst without warning.
Tip: Replace rubber hoses with braided stainless steel hoses every 3–5 years.
A $40 upgrade can prevent thousands in water damage.

Many homeowners don’t think about their sump pump until there’s a heavy rainstorm.
With Ontario’s spring melts and summer downpours, this small device protects your entire basement.
How to test it:
Pour a bucket of water into the pit. If it doesn’t activate immediately, it needs servicing.

Your garage door is likely the largest moving object in your home — and one of the most used.
Dry rollers and hinges strain the opener and can lead to premature failure.
Use a silicone-based lubricant on:
Rollers
Hinges
Tracks
Springs (lightly)
Do this once or twice per year.

When dust builds up behind your fridge, it forces the appliance to work harder.
Result:
Higher energy bills
Reduced lifespan
Risk of overheating
Pull the fridge out and vacuum the coils once a year.

Caulking around windows, doors, and tubs breaks down over time.
Cracks allow:
Water intrusion
Drafts
Increased heating costs
Rot and mold
In Ontario’s freeze-thaw climate, even small cracks can expand quickly.
Inspect caulking each fall and reapply as needed before winter.

Walk around your home and make sure the soil slopes away from your foundation.
Over time, soil settles and creates low spots where water pools.
Poor grading can lead to:
Basement leaks
Foundation cracks
Mold growth
Even a slight slope adjustment can prevent major structural issues.

Cleaning the lint trap is good — but lint builds up inside the vent line too.
A clogged dryer vent:
Reduces efficiency
Increases fire risk
Raises energy costs
Have it professionally cleaned or use a vent brush kit annually.

Most homeowners don’t realize their shut-off valves are seized… until there’s a leak.
Turn each valve gently on and off once a year to keep them functional.
In an emergency, working shut-offs can prevent major damage.
Breaking tasks down by season makes them easier to manage:
Test sump pump
Inspect grading
Check exterior caulking
Clean bathroom fans
Lubricate garage door
Clean dryer vent
Vacuum fridge coils
Flush hot water tank
Seal gaps and cracks
Check weather stripping
Exercise shut-off valves
Monitor attic condensation
Watch for ice buildup near foundation
If you’re ever planning to sell, buyers notice signs of neglect quickly:
Water staining
Musty smells
Drafty windows
Aging appliances
Small maintenance issues signal bigger potential problems in a buyer’s mind — which can affect offers and negotiations.
A well-maintained home:
Shows pride of ownership
Reduces inspection surprises
Commands stronger resale value
Sells faster in competitive markets
Think of maintenance as protecting both your comfort and your equity.
