How Texas Weather Destroys Commercial Windows—And How to Stop It

Texas weather doesn’t just test your patience—it tests your property. From brutal summer heat to unpredictable storms and hard water buildup, your commercial windows face more punishment than you might realize. Over time, that exposure leads to clouded glass, damaged seals, corrosion, and expensive repairs—all avoidable with the right maintenance routine.

At Davis Window Cleaning Company, we’ve seen firsthand what Texas weather can do to business windows—and more importantly, how to stop it. Here’s what every business owner in Fort Worth, Keller, Southlake, and surrounding areas should know about protecting their investment.

The Harsh Truth About Texas Weather and Your Windows

Texas may be known for its sunshine, but the same climate that makes our state beautiful also causes year-round challenges for commercial buildings. The mix of heat, humidity, wind, dust, and mineral-heavy rainwater is a perfect recipe for long-term window damage.

Let’s break down the biggest culprits.

1. The Texas Sun: UV Rays and Thermal Stress

The Texas sun is relentless. Prolonged exposure to ultraviolet (UV) rays and high heat doesn’t just fade furniture—it also weakens and distorts your glass over time.

• Thermal stress cracks happen when one part of a window heats faster than another. This creates pressure that can cause cracking or warping, especially in larger panes or tinted glass.
• UV rays damage window seals and coatings, allowing moisture and dirt to creep between panes.
• Constant sunlight amplifies water spots and mineral buildup, baking them onto the glass until they become nearly impossible to remove.

Regular professional cleaning removes buildup before the sun “bakes” it in permanently, keeping your glass clear and structurally sound.

2. Hard Water Stains from Sprinklers and Rain

If you’ve ever seen white, chalky spots on your windows, you’re looking at hard water damage. In Texas, our water supply has a naturally high mineral content—especially calcium and magnesium. When sprinkler overspray or rainwater dries on your windows, it leaves behind those minerals.

Over time, those spots bond to the glass surface and start to etch microscopic scratches into it. Once that happens, it’s no longer just a cosmetic issue—it’s permanent damage.

Professional window cleaning eliminates these mineral deposits using specialized, non-abrasive solutions designed to lift them safely without harming the glass.

3. Dust, Pollen, and Wind Damage

Anyone who’s lived in Texas knows dust and pollen season is no joke. Strong winds carry grit, sand, and airborne debris that sticks to your windows and works like sandpaper when not cleaned off regularly.

This constant abrasion wears down both glass surfaces and window frames, dulling their shine and shortening their lifespan. It’s especially harsh for businesses near busy roads, construction zones, or open landscapes.

Routine cleaning removes these abrasive particles before they cause scratches and keeps your windows clear, bright, and professional-looking.

4. Rain, Humidity, and Seal Damage

Texas weather loves extremes. One day it’s dry and windy, the next it’s humid and raining sideways. That rapid shift in moisture can wreak havoc on your window seals and frames.

• Humidity builds mold and mildew around window tracks, creating unpleasant smells and potential air quality issues.
• Rainwater seeps into cracks and seals, leading to fogging between panes.
• Metal frames corrode, while wooden frames swell, crack, or rot over time.

Professional cleaning includes wiping down and inspecting frames and seals—stopping damage before it spreads and saving you from expensive replacements.

5. Storms and Hail: The Sudden Threats

Texas storms are unpredictable, and they bring more than rain. High winds, hail, and flying debris can chip, crack, or pit your windows.

While cleaning can’t prevent hail, regular maintenance helps spot existing weaknesses before storms make them worse. A professional inspection can detect loose panes, failing seals, or cracks early, giving you time to fix issues before severe weather hits.

The Real Cost of Neglecting Weather Damage

Ignoring weather-related wear and tear doesn’t just hurt appearances—it costs you money.

• Reduced energy efficiency: Damaged seals let hot air in and cool air out, spiking your utility bills.
• Permanent glass damage: Etched or fogged windows require costly replacement, not repair.
• Declining curb appeal: Dirty, weathered windows make your building look neglected and unprofessional.
• Increased maintenance costs: Delaying cleaning and inspections leads to more expensive long-term problems.

In short, weather happens—but neglect makes it worse.

How to Protect Your Windows from Texas Weather

You can’t control the elements, but you can control how your business prepares for them. Here’s how:

• Schedule regular cleanings. For most Texas businesses, exterior windows should be cleaned every 1–3 months. Retail and restaurant locations exposed to landscaping or sprinklers should clean every 2–4 weeks.
• Use professional-grade cleaning. Avoid DIY cleaning that can leave streaks, residue, or even scratches. Professionals use pure water systems and eco-friendly solutions that clean deeper without damage.
• Inspect frames and seals regularly. A professional cleaner can spot corrosion, loose seals, or fogging early—before they become expensive repairs.
• Protect landscaping zones. Redirect sprinklers or adjust timers to minimize overspray onto windows.
• Clean after major storms. Post-storm cleaning removes debris, mud, and mineral deposits before they set in.
