Prep Your Stucco for the Brisk Ottawa Cold with CertaPro Painters
Posted on September 5, 2024
When Ottawa’s temperature drops, homeowners know it’s time to prepare their homes for the long winter ahead. For those with stucco exteriors, winter prep is especially important to prevent moisture damage, cracks, and other cold-related issues. While stucco is a durable and energy-efficient choice for homes, it does require maintenance to withstand Ottawa’s harsh winters. This guide outlines essential steps for preparing stucco exteriors for cold weather and how CertaPro Painters of Ottawa can help ensure your stucco surfaces are protected and looking their best.
1. Inspect Your Stucco for Damage
Before winter hits, it’s critical to assess the condition of your stucco. Look for any cracks, chips, or areas where the material may have pulled away from the wall. Even small cracks can let moisture in, which can expand as it freezes, leading to more severe damage. The freeze-thaw cycle common in Ottawa winters can worsen these issues, resulting in costly repairs if left unchecked.
CertaPro Painters of Ottawa offers thorough inspections, focusing on identifying minor issues before they become major problems. Our team can spot areas needing attention and provide a plan for repairs to keep your stucco intact throughout the winter.
2. Address Cracks and Holes
Stucco may develop hairline cracks over time, especially with fluctuating temperatures. It’s crucial to repair these before the first freeze, as water can seep in, freeze, and expand, which will widen the cracks. Patch up any holes as well, as these are prime entry points for moisture.
CertaPro Painters of Ottawa uses high-quality, weather-resistant materials designed to withstand Ottawa’s freezing temperatures. Our experienced painters ensure each repair is sealed tightly, creating a barrier against moisture. Properly patching and sealing your stucco can extend the life of your exterior and prevent larger repairs in the future.

3. Clean the Stucco Surface
Dirt, mold, and mildew can accumulate on stucco, especially in areas with high moisture levels. Cleaning your stucco before winter is essential, as dirt can trap moisture against the surface, increasing the risk of damage. Regular cleaning also allows you to spot any underlying issues that may require attention.
Our team at CertaPro Painters uses gentle, effective cleaning methods to remove buildup without damaging the stucco. We recommend scheduling a professional cleaning before temperatures drop below freezing to ensure that your stucco is in the best shape possible. A clean surface not only looks better but also enhances the durability of any additional treatments.
4. Apply a Protective Sealant
Applying a sealant to your stucco exterior is one of the best defenses against moisture penetration. Sealants form a protective layer that keeps water out, which is especially important during Ottawa’s snow-filled winters. A good sealant will prevent water from soaking into the stucco and expanding when it freezes, which could lead to cracks and further issues.
CertaPro Painters of Ottawa offers high-quality sealant application services tailored for our cold climate. Our team selects a sealant that’s compatible with your stucco type and applies it evenly to provide long-lasting protection. We recommend reapplying a sealant every few years, and fall is an ideal time to do this before winter sets in.

5. Consider Repainting for Extra Protection
If your stucco is due for a repaint, autumn is a perfect time. A fresh coat of paint not only improves curb appeal but also adds an additional layer of protection. High-quality exterior paint acts as a sealant on its own, providing an extra barrier against moisture and cold.
CertaPro Painters of Ottawa specializes in repainting stucco with durable, weather-resistant paints that are designed to withstand extreme conditions. Our team understands the importance of proper preparation and applies paint in a way that maximizes longevity, ensuring your home’s exterior is not only beautiful but also winter-ready.
6. Check for Proper Drainage
Finally, make sure that water is directed away from your stucco exterior. Improper drainage can lead to water pooling against your stucco, which can cause damage over time. Ensure gutters are clean and downspouts are positioned to direct water away from your home.
While our focus at CertaPro Painters is on your home’s exterior, we can also advise on ways to protect your stucco through proper drainage. By combining these efforts with your regular stucco maintenance, you can significantly reduce the risk of winter damage.
