How to Choose the Best Window Glazing Company for Your Project

When it comes to restoring or maintaining a large-scale building—whether it’s a historic church, mid-century school, or a multi-unit residential complex—your windows play a crucial role in both aesthetics and performance. Choosing the right window glazing company can make all the difference in energy efficiency, weather protection, and maintaining architectural integrity.

At Corona Craft Restoration, we understand how important window systems are to the overall health and longevity of a building’s façade. If you’re looking to hire a window glazing company for your project, here are a few key things to consider.

Look for Experience With Large-Scale and Historic Projects

Not all glazing companies are equipped to handle the demands of commercial or historic buildings. These structures often have custom window openings, unique architectural details, or outdated systems that require expert attention. A company that specializes in glazing for high-rise residential, religious, or institutional buildings will have the equipment, training, and know-how to execute the work safely and efficiently.

Ask about past projects—have they worked on buildings similar to yours? A seasoned window glazing company should have a portfolio of completed jobs that showcase both technical skill and aesthetic sensitivity.

Verify Licensing, Insurance, and Safety Standards

Safety isn’t just a buzzword—especially when it comes to exterior glazing work several stories up. The best window glazing companies will have proper licensing, liability insurance, and a strong track record of job site safety. Ask about their safety protocols and certifications. A reputable company will be transparent and willing to walk you through their process.

At Corona Craft Restoration, we prioritize safety in every project we undertake, from façade inspections to glazing system repairs.

Evaluate Their Knowledge of Building Envelopes

Window glazing is more than just installing glass. It’s a critical component of your building’s envelope—the barrier between the interior and the elements. An expert glazing contractor should understand how the glass interacts with masonry, caulking, waterproofing, and insulation systems.

Look for a window glazing company that considers the full picture. Integration with existing materials, compatibility with sealants, and understanding thermal movement are all essential for long-lasting performance.

Ask About Material Options and Custom Solutions

Depending on your project, you may need custom glazing solutions to match historic profiles or improve performance without compromising appearance. Whether it’s insulated glazing units, laminated safety glass, or historically accurate single-pane glass, a skilled contractor will offer a range of solutions—and help you select the right one.

Be wary of a one-size-fits-all approach. The best companies tailor their work to your building’s unique needs, combining modern performance with timeless design.

Consider Maintenance and Long-Term Support

Once your glazing system is installed or repaired, ongoing maintenance is key. Ask if the company offers inspections, sealant replacement, or ongoing façade restoration support. A company that stands behind its work will often offer long-term solutions—not just one-time fixes.

Corona Craft Restoration takes pride in offering full-envelope services, ensuring that your windows, masonry, and sealants work together to protect your building for years to come.

Building Better With the Right Window Glazing Partner

Choosing the right window glazing company isn’t just about glass—it’s about trust, technical expertise, and a shared commitment to preserving your building’s value and appearance. Whether you’re working on a historic restoration or upgrading aging components, partnering with an experienced contractor can make all the difference.
