Installing glass in a commercial building is only the beginning. Proper maintenance is essential to keeping it looking great and performing well for years. Whether you’re working on a storefront in Dallas or a curtain wall in Kansas City, a good maintenance routine saves your client money and protects your reputation as a contractor.
Here’s what glazing and general contractors in Texas, Oklahoma, and surrounding states need to know about maintaining commercial glass properly.
Why Maintenance Matters
Glass might look low-maintenance, but it takes a beating—sun, wind, pollution, and physical impact can all reduce its clarity and performance. If your client invested in quality materials like insulated glass units (IGUs), Low-E coatings, or laminated safety glass, they’ll only get their money’s worth if that glass is appropriately maintained.
Unmaintained glass leads to:
- Stains or corrosion from hard water
- Reduced energy efficiency due to dirt and debris
- Frame and seal failure
- Shortened lifespan of IG units
Prevention is cheaper than replacement—especially when you’re dealing with large commercial panels or specialty glass.
Best Practices for Glass Cleaning
- Use the Right Cleaning Products
Skip the ammonia-based cleaners and harsh chemicals. These can damage coatings and seals. Instead, use pH-neutral, non-abrasive cleaners and soft cloths or squeegees. - Stick to a Schedule
Set a regular cleaning schedule based on location and exposure. Busy urban storefronts might need monthly cleaning, while protected office windows may need attention quarterly. - Avoid High-Pressure Washing
High pressure can damage seals, especially around IGUs. For larger areas, use water-fed pole systems or professional cleaning crews with experience in commercial buildings. - Clean in the Shade
Direct sunlight causes cleaning products to dry too fast, leaving streaks and residue. Early morning or cloudy days are best for glass maintenance.
Inspect for Damage
Routine inspections are just as important as cleaning. Look for:
- Chips or cracks
- Fogging between panes (a sign of IGU failure)
- Broken seals or damaged gaskets
- Corrosion or wear on frames and hardware
Catch issues early, and you can repair instead of replace. Make it part of your service package or recommend a local professional to your client for routine inspections.
Maintain the Frame Too
The glass is only as good as the frame it sits in. For aluminum storefronts and facades:
- Keep weep holes clear for water drainage
- Check for oxidation or pitting on the aluminum
- Lubricate any moving hardware like closers or pivots
- Ensure sealant joints are intact and flexible
Well-maintained frames prevent leaks, drafts, and thermal loss—major concerns in extreme climates like those in Texas and New Mexico.
Special Considerations for Coated or Tinted Glass
Low-E, mirrored, or tinted glass needs extra care. Avoid abrasive cloths or metal scrapers. Even a small scratch can ruin a coating. Make sure building maintenance teams are trained—or supply a glass care guide to your clients post-installation.
Train the Client
One of the easiest ways to ensure long-term performance is to educate the client. Offer a maintenance checklist at project closeout or schedule a short walkthrough. It builds trust, improves satisfaction, and positions you as a reliable partner—not just an installer.
You can even upsell maintenance packages or build long-term relationships with property managers and developers who need ongoing support.
