Window Repair

Emergency Services

When a window in your home is broken or shattered, contact our team at any hour for emergency glass repair. We understand a broken window poses a hazard to your safety and security, and you should never have to wait until tomorrow to have it repaired. When you contact Glass Doctor of Northwest Indiana, our team will arrive promptly at your home to mend your damaged window. If a pane must be ordered to complete the repair, our glass specialists will board up the window, clear the area of broken glass and debris, and return at the time of your choosing to finish restoring your window.

Double Pane Window Repair

Double pane windows provide significant energy-saving advantages to homeowners. Valparaiso residents count on Glass Doctor of Valparaiso to keep their panes in good repair. If condensation has collected between the panes or a foggy appearance mars the glass, your windows most likely have broken seals. Glass Doctor of Northwest Indiana will repair the seal or replace the pane to boost your curb appeal, improve insulation and keep your house comfortable.

Specialty Glass Repair

Our experts are trained well beyond basic window replacement, and will tackle any glass repair or installation, including door glass, mirrors, cabinets, shower doors and glass decor of all kinds.

Window Replacement

We always try to save you money by repairing a window rather than replacing it, but if you need a new window, you can trust our specialists to select the right window for your needs. We have a wide variety of insulated glass units (IGUs) to choose from, including double and triple pane windows.


Glass enhancements from Glass Doctor of Northwest Indiana offer advantages like lower energy bills and greater comfort. New and advanced glass options like IGUs and low-emissivity windows allow every homeowner in the Valparaiso and Portage to take advantage of these benefits. Ask our experts about replacing worn or broken windows with newer models that will increase home value and comfort.
