Calgary's winters are legendary for their dramatic temperature swings, heavy snowfall, and biting winds. While we bundle up to stay warm, what about our homes? The exterior paint on your house takes a constant beating from these elements, and without proper care, its lifespan can be significantly shortened. At Mellow Yellow Painting, we not only apply high-quality, durable exterior finishes but also believe in empowering Calgary homeowners with the knowledge to protect their investment.
Ensuring your exterior paint withstands the harsh Alberta winter is crucial for maintaining your home's curb appeal and structural integrity. Here's your essential guide to exterior paint care to help your home look its best, even when the snow flies.
Understanding Winter's Impact on Exterior Paint
Calgary's unique climate poses several challenges for exterior paint:
Freeze-Thaw Cycles: Rapid temperature fluctuations cause materials to expand and contract, leading to cracking, peeling, and blistering of paint.
Moisture: Snow, ice, and melting water can penetrate compromised paint, leading to wood rot, mildew, and paint failure.
UV Radiation: Even in winter, sunlight (especially reflected off snow) can cause paint to fade and chalk.
Wind & Abrasion: Strong winds can carry abrasive particles that wear down the paint surface.
Pre-Winter Exterior Paint Care: The Best Defense
The best way to protect your exterior paint is through proactive measures before winter truly sets in.
Thorough Cleaning:
Wash Your Siding: Before temperatures drop consistently below freezing, give your home's exterior a good wash. Use a mild detergent and a soft brush or a low-pressure power washer (carefully!) to remove dirt, grime, and mildew. Clean surfaces allow paint to adhere better and reveal any issues.
Clean Gutters & Downspouts: Clogged gutters can lead to ice dams and water overflowing onto your paint, causing significant damage. Ensure they are clear of leaves and debris.
Inspect for Damage & Address Small Repairs:
Look for Cracks & Peeling: Walk around your home and meticulously inspect for any signs of cracking, peeling, blistering, or chipping paint. These are entry points for moisture.
Seal Gaps & Cracks: Use high-quality exterior caulk to seal any gaps around windows, doors, and trim. This prevents water from getting behind the paint and into the structure.
Minor Paint Touch-Ups: For small areas of peeling or damaged paint, gently scrape away loose paint, sand the edges, prime, and apply a matching topcoat. Addressing these now prevents them from becoming larger issues under winter stress. For larger touch-ups or extensive damage, consider consulting Mellow Yellow Painting.
Ensure Proper Drainage:
Check Grade Around Foundation: Ensure the ground slopes away from your house to direct melting snow and rain away from the foundation and siding.
Extend Downspouts: Use extenders to ensure downspouts drain water well away from your home's exterior walls.
During-Winter & Post-Winter Maintenance Tips
While pre-winter prep is key, a few ongoing habits and post-winter checks can make a big difference.
Avoid Salt Splatter: If you use de-icing salts on walkways or driveways, try to keep them away from your home's painted surfaces, as salt can be corrosive.
Gentle Snow Removal: When clearing snow from decks or areas adjacent to your house, be mindful not to scrape or damage painted surfaces with shovels or snow blowers.
Post-Winter Inspection: Once the snow melts and temperatures rise consistently above freezing, conduct another thorough inspection. Look for any new cracks, peeling, or signs of moisture damage that may have occurred over winter. Address these promptly.
