If My Home's Exterior Needs Repainting?
A Guide by CertaPro Painters® of Markham, ON
What Are The Signs A Home Needs Exterior Painting?
The signs can be subtle at first, but ignoring them can lead to bigger issues over time. In this guide, we’ll help you identify the most common warning signs of exterior damage, explain the benefits of repainting, and answer the most frequently asked questions from Markham-area homeowners. If you’re wondering whether it’s time to repaint your home’s exterior, this page will walk you through what to look for.
1. The Paint's Resin Has Worn Off
When you rub your hand on the exterior siding or trim, chalk appears on your hand. Over time, the paint's resin wears away, leaving behind the pigment (chalking).
2. Faded or Discolored Paint
You may notice your once-vibrant home is looking faded and weathered. Sun exposure and the elements cause colors to fade over the years.
3. Water Intrusion or Signs of Water Damage
Indoor leaks are a sign of exterior problems. For old paint layers, water can also get behind the paint, and can cause bubbling, rotting, peeling, and further damage.
4. Wood Rot on Clapboards, Shingles, or Trim
When wood is exposed to moisture over time, rotting can occur. This often happens lower to the ground or near areas of water runoff.
5. Flaking or Cracked Paint
Old paint tends to flake and peel off. This exposes the wood underneath, which is vulnerable to moisture and pests.
6. Shrinking Caulk on Exterior Seams
The caulk seams of your home exterior may separate and come loose over time, giving water a path into your siding.
7. Visible Mold or Mildew Growth
This can often be seen as black growth on your shingles, but it is also common in dimly lit or shaded areas exposed to moisture.
8. Outdated Colors, Lower Curb Appeal
It may have been years since you updated your home's style. If you are looking to sell, or simply desire a new look, it can boost your curb appeal
9. Your Home is a Newer Construction
Builders often only apply 1 coat of paint. You will need proper surface preparation and 2 coats of paint to be fully protected.
What Are The Benefits of Exterior Painting?
Professional exterior painting is a smart investment in your property. Here are some of the key benefits:
- Boost curb appeal and property value
A fresh coat of paint gives your home a fresh, well-maintained look that makes a strong first impression. If you’re planning to sell, or just want to love the way your home looks, exterior painting increases the curb appeal and market value of your property. - Protect your home from the elements
In Markham’s climate, your exterior surfaces endure rain, snow, ice, and intense UV exposure. Our streamlined painting process includes expert surface preparation, light carpentry repair of damaged wood or siding, and professional coatings that create a lasting barrier.

"Had some exterior siding painted and dormer refreshed on my house prior to sale and it really made the house look about 30 years newer. The great work that was done by CertaPro helped me sell my house just before the market dived.
Thanks again for all your hard work and would highly recommend!"

How Often Should A Home Exterior Be Repainted?
Most homes need exterior repainting every five years, but this can vary depending on the material of your siding, prior paint quality, and level of exposure to weather. In Markham, the harsh winters and freeze/thaw cycles can accelerate paint deterioration. This is especially true if the home is older or hasn’t been maintained properly.
It’s also important to consider surface orientation. Paint and stain typically last longer on vertical surfaces like walls and siding, where water runs off and dries quickly. Contrast this with decks, railings, or porch roofs; horizontal surfaces that are more exposed to standing moisture, which causes finishes to wear out faster.
What Are The Best Months For Exterior Painting?
In the Markham region, the best time to repaint your home’s exterior is typically from May to early October. During this window, daytime temperatures are consistently above 10°C, which is the minimum needed for paint to cure properly and adhere to surfaces.
Weather conditions also matter. Paint shouldn’t be applied to wet surfaces for the same curing reasons, and it’s important to avoid days that are too humid or rainy. Fog, morning dew, and spring showers can delay work if the surface hasn’t had time to dry fully.
Planning ahead is key. Spring and Fall weather can be unpredictable, so planning your painting project early helps keep your project on track despite any delays in weather. When you work CertaPro Painters® of Markham, ON, we account for all these factors during our initial free estimate appointment, so you can be confident your project is in good hands.
"After meeting Catherine, we were very comfortable in using CertaPro Painters to do some exterior painting on our steel entrance doors, garage doors and all of their wood frames.
Communication with a quote and scheduling a day for the job was fast and efficient. Guillermo was the painter who did the job and he was great. Friendly, cleaned up when he was finished and did a very nice job. We were impressed with how organized and professional CertaPro was. Now we know who to call for our next painting job."
