Failed insulated glass units — any size, any thickness. We source direct from local fabricators and replace IGUs efficiently across your entire property portfolio.
Call 724.858.2721 for a Free AssessmentInsulated glass units (IGUs) consist of two or more panes of glass sealed together with a space between them, typically filled with argon or air. That seal is what gives the window its insulating value.
Over time — usually 10 to 20 years in a commercial or multi-family setting — those seals fail. When they do, moisture enters the space between the panes. You see it first as slight cloudiness or haze. Over months it becomes visible fogging, streaking, or white mineral deposits on the interior glass surfaces that can't be cleaned.
Once the seal fails, the problem only gets worse. The glass cannot be repaired — the entire unit must be replaced. And in a multi-family property, when one unit starts going, others are usually not far behind.
RWC Glass has ongoing relationships with glass fabrication facilities in the Pittsburgh region. We buy direct off the factory floor — which means we're not paying a distributor or a middleman markup, and neither are you.
We can match the thickness, coating, tint, and specifications of your existing windows so replacements are seamless and consistent across your property.
Replacing 5 units and replacing 50 units are both things we handle. We can batch orders for efficiency and schedule work around tenant turnover to minimize disruption.
If you have widespread IGU failure across a property, we can help you build a multi-year replacement program — addressing the worst units now and working through the rest systematically.
Multi-family properties present a specific challenge with fogged IGUs. Units age together. If a building was constructed or last reglazed in a particular decade, the seals across the entire building tend to fail around the same time.
Property managers often discover this when maintenance requests for "foggy windows" start coming in from multiple units at once. What looks like isolated incidents turns out to be a building-wide issue that's just starting to surface.
RWC Glass works with maintenance supervisors to identify the scope of the problem early — before tenant complaints multiply — and develop a realistic plan that the ownership group can budget for over time rather than facing as a sudden capital crisis.
Fogged glass is more than an aesthetic problem. Tenants notice it. It communicates that the property isn't being maintained. In competitive rental markets, it affects lease renewals and the quality of residents a property attracts.
Replacing fogged glass during unit turnover — before new tenants move in — is the cleanest approach. RWC Glass works with property managers to establish a standing protocol: when a unit turns over, we assess the glass and replace what's failed. The new tenant never sees the problem.
We understand that large property glass programs require approval from ownership. We can provide written assessments, unit-by-unit documentation, and program pricing that gives ownership the information they need to make a decision and budget appropriately.
