Ottawa’s weather is tough on exterior surfaces. Between freezing winters, humid summers, snow buildup, and strong UV exposure, your home’s paint constantly expands, contracts, and absorbs moisture. One of the most common questions homeowners ask is how often they should repaint to keep their property protected and looking its best.
Below, Randall’s Painting answers the most frequently asked questions about exterior repainting in Ottawa.
How Often Should You Repaint a House Exterior in Ottawa?
In Ottawa’s climate, most homes should be repainted every 5 to 10 years. However, the exact timeline depends on the surface material:
-
Wood siding: 5 to 7 years
-
Aluminum siding: 5 to 10 years
-
Stucco: 7 to 10 years
- Painted brick: 10 to 15 years
Homes exposed to strong sunlight, heavy wind, or moisture may require repainting sooner.

Why Does Ottawa’s Climate Shorten Paint Lifespan?
Ottawa experiences significant temperature swings throughout the year. These fluctuations cause siding and trim to expand and contract, which stresses the paint film.
Other contributing factors include:
- Freeze and thaw cycles
- Snow and ice buildup
- High summer UV exposure
- Humidity and rain
Proper preparation and high quality materials are essential to ensure long lasting protection.
What Are the Signs It’s Time to Repaint?
Even if you are unsure when your home was last painted, there are clear warning signs:
- Peeling or flaking paint
- Fading or discoloration
- Cracked caulking
- Bubbling or blistering
- Exposed wood or siding
- Mold or mildew stains
If you notice any of these issues, it may be time for an inspection.

Can You Wait Until Paint Is Peeling?
It is not recommended. Exterior paint acts as a protective barrier. Once it begins to fail, moisture can enter the surface and lead to:
- Wood rot
- Structural damage
- Mold growth
- Higher repair costs
Repainting before major failure saves money and prevents larger restoration work.
Does Quality of Previous Work Affect How Long Paint Lasts?
Absolutely. The durability of your exterior paint depends heavily on:
- Surface preparation
- Cleaning and sanding
- Priming
- Professional application
- Product quality
A properly prepared and professionally applied paint system can last significantly longer than a rushed or DIY job.

When Is the Best Time to Repaint in Ottawa?
The best time for exterior painting in Ottawa is typically late spring through early fall, when:
- Temperatures stay above 10°C
- Humidity is moderate
- Surfaces are dry
- Rain is minimal
Painting during proper weather conditions ensures better adhesion and longer lasting results.
Does Colour Choice Impact Longevity?
Yes. Darker colours absorb more heat, which may cause faster fading or stress on certain surfaces. Lighter shades often retain their appearance longer under strong sun exposure.

Is Repainting Worth It Before Selling?
