Ottawa's humidity makes AC non-negotiable. Don't wait until the first heatwave — HVAC companies book up fast. Here's what to do now:
Ottawa's freeze-thaw cycle is brutal on exteriors. Summer is your window to assess and repair:
Check for missing shingles, damaged flashing, and clogged gutters. Summer storms can turn small leaks into big damage fast.
Look for cracks and ensure soil slopes away from your foundation. Proper grading prevents basement flooding during heavy rains.
Repair loose siding and touch up peeling paint. Summer's dry weather is ideal for exterior painting projects.
Check weatherstripping and caulking. Air leaks waste energy and let in humidity. Reseal where needed.
Ottawa summers were made for outdoor living. Here's how to maximize your space while protecting your property:
| Task | Why It Matters | Pro Tip |
|---|---|---|
| Tree & branch trimming | Dead branches can fall during summer storms | Hire a certified arborist for branches near power lines |
| Lawn care & fertilization | Healthy lawns resist pests and drought | Water deeply but infrequently to encourage deep roots |
| Deck & fence inspection | Wood can rot or warp from winter moisture | Power wash and reseal every 2-3 years |
| Irrigation system check | Leaks waste water and money | Run each zone and watch for broken heads |
| Patio & walkway repair | Uneven surfaces are safety hazards | Address trip hazards before entertaining season |
From mosquitoes breeding in standing water to carpenter ants looking for damp wood, summer pests are more than a nuisance — they can cause real damage:
Ottawa's humid summers are prime time for basement issues. Here's what to check inside:
Run a dehumidifier to keep basement humidity below 50%. Empty and clean the reservoir regularly to prevent mold.
Test all detectors and replace batteries. Summer storms can cause power surges that trip hardwired systems.
Reverse fan direction for summer (counterclockwise) to push cool air down. Clean blades to avoid dust circulation.
