Why Is Your Paint Peeling? Common Causes Every St. Louis Homeowner Should Know

As a trusted residential and commercial painting company serving the St. Louis metro area, we at Malone Painting have seen our fair share of peeling paint—on interior walls, ceilings, exteriors, trim, and more. And while each peeling paint scenario is a little different, they all have one thing in common: they’re frustrating for homeowners who’ve invested time and money into making their homes look beautiful.

If you’re dealing with paint that’s bubbling, cracking, or flaking, don’t worry—you’re not alone. Let’s explore the most common causes of peeling paint and how Malone Painting helps St. Louis homeowners prevent and fix these issues for long-lasting, professional results.

A Real St. Louis Paint Problem: Poor Prep and Moisture

Recently, a client in Webster Groves called us after noticing peeling paint in their recently renovated kitchen. The paint was bubbling and flaking near the windows and sink just a few months after the project was completed by another contractor. After a thorough inspection, we discovered the root of the problem: poor prep work, excess moisture, and substandard paint.

This kind of issue is extremely common in the humid St. Louis climate, especially in older homes found in neighborhoods like Kirkwood, Clayton, and South City. Here's what caused the peeling—and how we fixed it.

Top 5 Causes of Peeling Paint (and How Malone Painting Solves Them)

1. Excess Moisture

High humidity, poor ventilation, and leaks are major culprits behind peeling paint—especially in St. Louis kitchens, bathrooms, and basements. In our client’s case, steam and condensation around the kitchen sink led to moisture seeping behind the paint.

Our Solution:

We repaired the damaged drywall and applied a moisture-resistant primer formulated for high-humidity areas. We also advised the homeowner to install better ventilation and address window condensation to prevent future issues.

2. Inadequate Surface Preparation

Proper prep is critical in a climate like St. Louis’s, where seasonal changes can impact paint adhesion. Skipping essential steps like cleaning, sanding, or priming leads to premature failure—something we often see in DIY or low-budget jobs.

Our Solution:

We cleaned all surfaces with a degreasing agent, sanded the area thoroughly, and applied a high-adhesion primer. We never cut corners—especially during prep—because that’s what ensures our paint jobs last for years.

3. Using the Wrong Paint

Not all paints are created equal. In environments prone to moisture or temperature fluctuations, using low-grade or mismatched paint can result in blistering or peeling. The previous contractor had used a standard interior paint not designed for kitchen conditions.

Our Solution:

We used a premium, washable, moisture-resistant paint specifically made for high-traffic, high-humidity rooms. It’s more durable, easier to clean, and built to withstand real-world wear—perfect for busy St. Louis households.

4. Painting Over Damaged or Flaking Paint

Applying new paint over old, peeling layers may look fine initially—but it won’t last. If the base layer is compromised, the topcoat will eventually follow suit.

Our Solution:

We stripped away all peeling layers, patched the walls, and sanded the surface smooth. Then we primed and repainted the area with high-performance paint, giving the kitchen a durable and flawless finish.

5. St. Louis’s Seasonal Weather Extremes

From hot, muggy summers to icy winters, St. Louis weather creates stress on both interior and exterior surfaces. This freeze-thaw cycle can cause materials to expand and contract, leading to paint failure.

Our Solution:

For exteriors, we use weather-resistant, flexible paints that can handle St. Louis’ seasonal swings. For interiors, we advise temperature regulation and dehumidification to protect painted surfaces year-round.
