Window Glazing Services in the Chicago Area
At Corona Craft Restoration, we specialize in providing top-tier window glazing services for both commercial and residential properties.
With over 20 years of experience in the industry, we bring dedicated craftsmanship and a commitment to quality to every project we take on. Window glazing is one of those details that affects your building's energy performance, security, and appearance all at once, and it's closely connected to the broader health of your building envelope. We approach it with the same thoroughness we bring to services like caulking, flashing systems, and concrete facade repair.
What is Window Glazing?
Window glazing refers to the process of installing, repairing, or replacing glass panes within a window frame, secured with glazing compound, putty, or other setting materials. Far more than just placing glass in a frame, proper window glazing creates a tight, weather-resistant seal that holds the glass securely, prevents air and water infiltration, reduces noise, and contributes to the thermal performance of the building.
In older Chicago buildings, single-pane windows with traditional glazing putty are common. Over time, glazing compound dries out, cracks, and pulls away from the glass and frame, creating gaps that allow water to enter and accelerate deterioration of the surrounding wood or metal frame. Failed glazing is one of the most overlooked sources of moisture damage in historic buildings, and it's a problem that compounds quickly once it begins.
For commercial buildings and newer construction, glazing work often involves more complex systems, including curtain wall glazing, storefronts, and multi-pane insulated glass units. Our team has the experience to work across the full range of window systems common in Chicago's commercial and residential building stock.
How Window Glazing Connects to the Rest of Your Building Envelope
Window openings are one of the most common points of water entry in any building. Properly glazed windows are only part of the solution. The opening also needs proper flashing above and around it to direct water away, and properly applied caulking and sealant at the perimeter joint between the window frame and the surrounding masonry.
When we assess window glazing on a building, we look at the full opening, not just the glass. If the surrounding masonry has deteriorated, brick repair or limestone repair may be needed before glazing work begins. If the flashing above the opening is failed, our flashing system services address that as part of a coordinated scope. This integrated approach is what separates a repair that holds from one that fails again within a season.
For commercial storefronts, curtain wall systems, and large-format glazing, our team applies industry-standard installation techniques to ensure a secure, weather-tight, and visually consistent result.

Our Window Glazing Services
At Corona Craft Restoration, we offer a range of services tailored to meet the unique needs of each project:
Window frames that have been exposed to water infiltration through failed glazing often show signs of deterioration that need to be addressed before reglazing. We assess frame condition as part of our glazing evaluation and recommend repairs as needed before installing new glazing.
Frame Assessment and Repair
Once glazing work is complete, the perimeter joint between the frame and the surrounding facade is sealed with high-performance sealant. This work is part of our broader caulking services and is a critical step in creating a complete weather barrier at the window opening.
Perimeter Caulking and Sealing
Where window openings lack proper through-wall flashing or have failed flashing above, we address this as part of the window project scope. Our flashing system services cover all aspects of window opening flashing.
Flashing Integration
For historic and older windows, we remove deteriorated glazing putty and replace it with compatible modern glazing compound, creating a tight, durable seal around each pane. This restores the window's weather resistance and helps preserve the original frame.
Glazing Compound Replacement
Cracked, broken, or deteriorated glass panes are replaced with appropriately matched glass, including matching glass type, thickness, and in the case of historic properties, glass character. We handle everything from individual pane replacement to full sash regalzing.

Frequently Asked Questions
How do I know if my windows need reglazing?
Signs include cracked, dried, or missing glazing compound, rattling glass panes, visible gaps between the glass and frame, water staining on interior sills or walls near windows, and condensation between panes on insulated glass units. Any of these warrant a professional assessment.
Can glazing work be done without replacing the windows entirely?
In most cases, yes. Reglazing restores the weather resistance of existing windows without the cost of full window replacement. For historic buildings where preserving the original windows is important, reglazing is typically the preferred approach.
Does window glazing need to be done before or after masonry repair?
It depends on the situation. If the surrounding masonry is deteriorated and needs to be repaired or repointed first, that work should be completed before glazing. If the masonry is in good shape, glazing can proceed independently. We assess the full opening condition during our inspection and sequence the work accordingly.
Juan and his team are extremely organized, they provide schedules of the work that needs to be done and the work is always completed following those timelines while staying within budget. The work is done correctly according to the specifications submitted by the engineering firm. I wouldn't change a thing — the Board and Management are extremely pleased with CCR. The project that was awarded them is the largest capital project ever undertaken by the Association. We very much appreciate Juan's diligence and his leadership.
