At Mountain West Painting, your trusted painting company in Evergreen, CO, we understand the importance of maintaining your home’s exterior to its finest. That’s why we’ve compiled 6 exterior painting warning signs that point out when it’s time to call in the professionals for a refresh.

The Importance of Timely Exterior Repaints

A timely repaint isn’t just about maintaining your home’s appearance—it’s a crucial part of home maintenance that protects your property from the elements. When paint begins to fail, your home’s siding becomes vulnerable to moisture, insects, and even rot. These issues, if left unchecked, could lead to costly structural repairs.

Moreover, fading and peeling paint can significantly decrease the curb appeal and value of your home. To prospective buyers, a house in need of repainting may signal neglected maintenance. So, staying on top of your home’s exterior painting needs can help preserve and even boost your property’s value.

Paint is your home’s first line of defense against the elements, and regular repaints ensure that this protection remains effective. Thus, it’s essential to watch out for the warning signs of deteriorating exterior paint.


One of the first signs that it’s time for a repaint is chalking. When the binders in paint break down due to exposure to sun and weather, a powdery residue forms on the surface, commonly known as “chalking.” Chalking is like a silent whisper from your house, indicating that the protective layer of paint is gradually losing its effectiveness.

When you notice chalking, it’s crucial to take action swiftly. Ignoring this subtle sign can lead to further paint degradation, leaving your home vulnerable to weather and aging. Like solving a mystery before it unfolds, catching chalking in its early stages can prevent unnecessary damage to your home.


The radiant Colorado sun is a blessing for outdoor enthusiasts, but it can be a curse for your home’s exterior paint. Prolonged exposure to sunlight can cause paint colors to fade over time, detracting from your home’s aesthetic appeal. However, fading is more than just an aesthetic issue. It can be an indication that the paint is losing its protective qualities.

Not all paint colors fade at the same rate. Darker colors tend to absorb more UV rays and are therefore more prone to fading. If you notice significant fading, especially on sun-exposed walls, it’s likely time to consider a fresh coat of paint.

Peeling or Cracking

If your paint is peeling or cracking, it’s a clear sign that the protective layer is failing. This not only tarnishes the look of your home but also exposes the underlying material to harsh weather conditions. Cracking usually begins with small, hairline cracks before developing into wider ones.

Once these wide cracks start to peel off, moisture finds an easy path to the underlying material. Over time, this moisture can cause significant damage, including rotting of the wood beneath. When you notice cracking or peeling, it’s best to address it promptly. The longer you wait, the higher the chance of moisture damage to your home.

Bubbling or Blistering 

Paint that is bubbling or blistering can indicate trapped moisture or heat beneath the paint surface. These bubbles can eventually lead to peeling or cracking, exposing the underlying material to potential damage.Bubbling or blistering often indicates that the paint isn’t adhering correctly to the surface beneath.

It could result from painting over a dirty or damp surface or could be due to the application of oil-based paint over latex paint.If you notice bubbling or blistering, you’ll likely need to scrape and sand the area and then repaint. Remember, it’s crucial to identify and address the underlying issue to prevent future blistering.

Rot or Mold

One of the more severe signs that it’s time for a repaint is the presence of rot or mold. These fungi can indicate significant water damage and can have serious health implications if left untreated.

According to the Environmental Protection Agency, mold can cause respiratory issues and other health problems, especially in people with mold allergies or compromised immune systems. If you notice mold on your home’s exterior, it’s crucial to address the problem promptly, starting with a thorough cleaning and followed by repainting with mold-resistant paint.

Similarly, rot can compromise the structural integrity of your home. While repainting can help protect the wood from further rot, you’ll likely need to replace any already rotted wood before repainting.

Hardened Caulk

Caulk is often the unsung hero of exterior painting. It seals gaps and cracks around windows, doors, and other openings, providing an extra layer of protection against moisture and drafts. Over time, caulk can become hard and lose its flexibility, leading to cracks and gaps. If the caulk around your windows and doors has become brittle or cracked, it might be time to repaint.

However, repainting involves more than just applying a new layer of paint. It’s also about ensuring that the surface is well-prepared and properly sealed, and this includes replacing any hardened or cracked caulk. Repainting your home is a perfect opportunity to address any issues with your caulking and ensure your home is well protected against the elements.

When to Consult Professional Painters

While some minor paint issues can be handled with DIY methods, many problems are best left to professionals. Knowing when to call in professional painters can save you time, effort, and the potential hassle of further repair costs.

Professional painters can help identify the underlying issues causing paint deterioration and provide a comprehensive solution, from preparing the surface to applying the final coat of paint. Moreover, professionals can often complete the job more efficiently and achieve a smoother, more durable finish than the average homeowner.
