Pittsburgh property managers know better than anyone how tough the local climate can be on commercial buildings. Between year-round moisture, rapid temperature swings, and harsh winters, properties in Western PA face conditions that make exterior cleaning and preventative maintenance essential—not optional.

If you manage office buildings, retail centers, apartment complexes, or industrial properties, understanding how our regional weather affects exterior surfaces can help you prevent damage, avoid costly repairs, and maintain strong curb appeal for tenants and visitors.

Below is a breakdown of the most common weather-related exterior issues in Pittsburgh—and how to protect your properties before they become liabilities.

---

1. Excess Moisture = Algae, Moss, and Mold Growth

High humidity, rainfall, and shaded areas create perfect conditions for biological growth on:

• Siding and facades
• Roof shingles
• Retaining walls
• Walkways and stairways
• Brick and stone surfaces

This growth is more than an appearance issue—it can cause premature material deterioration and slippery surfaces that increase liability risks.

How Soft Washing Helps

Soft washing safely removes organic growth at its root using low-pressure equipment and professional-grade solutions. It’s the ideal method for:

• Apartment buildings
• Office exteriors
• Retail storefronts
• EIFS and stucco surfaces

2. Freeze–Thaw Cycles Create Cracks in Concrete & Masonry

Pittsburgh winters bring constant freezing and thawing. Water seeps into pores and micro-cracks in:

• Sidewalks
• Parking lots
• Entry pads
• Brick patios
• Retaining walls

When it refreezes, it expands—leading to cracks, spalling, and uneven surfaces that accelerate long-term damage.

How Pressure Washing + Sealing Helps

Professional pressure washing removes dirt, salt, and grime, while concrete sealing protects surfaces from moisture absorption and freeze-related expansion.

3. Road Salt & De-Icing Chemicals Cause Surface Damage

Snow removal on commercial properties often requires salt and chemical de-icers. But over time, these compounds:

• Corrode metal railings
• Eat into concrete
• Stain siding
• Accelerate degradation around entry areas

Regular cleaning after winter prevents long-term structural deterioration and keeps high-traffic areas looking professional.

4. Heavy Rainfall Leads to Gutter Overflow & Water Intrusion

Clogged or underserviced gutters are a top cause of water damage in commercial buildings. Pittsburgh’s heavy rainfall overwhelms systems quickly, leading to:

• Foundation leaks
• Soil erosion
• Fascia damage
• Basement moisture
• Flooded walkways and entrances

Why Property Managers Should Schedule Routine Gutter Cleaning

Twice-yearly gutter cleaning—spring and fall—protects both the roofline and the property’s structural integrity.

5. Airborne Pollution Creates Black Streaks & Staining

Pittsburgh’s industrial heritage and active roadways create a constant buildup of:

• Soot
• Diesel particulates
• Dust
• Traffic film

This affects commercial facades, especially concrete, stucco, and metal siding near highways or high-traffic corridors.

Building Washing Restores Professional Appearance

Professional exterior cleaning removes these contaminants safely, preserving paints, coatings, and commercial branding.

---

6. UV Exposure Fades Exterior Surfaces & Signage

Direct sunlight causes:

• Faded siding
• Deteriorated trim
• Damaged signage
• Weakening of protective coatings

Regular cleaning helps maintain the lifespan of paints and finishes by removing contaminants that accelerate UV damage.
