Can Ottawa post-construction cleaners fix scratched glass or do I need a glass repair specialist?

Post-construction cleaning professionals cannot repair scratched glass — they focus on removing construction debris, dust, paint spots, and adhesive residue from glass surfaces, but scratched or damaged glass requires a specialized glass repair technician or complete replacement.

Most Ottawa cleaning contractors carry glass-safe solvents and use proper techniques to remove construction-related contaminants from windows without causing additional damage. They use razor blades to carefully scrape off paint overspray, adhesive residue from protective films, and concrete splatter. Professional cleaners also have the right cloths and squeegees to clean new glass without introducing scratches during the cleaning process itself. However, once glass is already scratched from construction activity — whether from grinding sparks, dragging tools across windows, or cleaning with contaminated cloths that contained grit — the damage is permanent and beyond what cleaning can address.

In Ottawa's construction market, scratched glass is unfortunately common during renovation and new build projects. The extreme temperature swings from minus 30 to plus 35 degrees Celsius cause building materials to expand and contract, sometimes shifting protective coverings on windows. Construction dust becomes especially abrasive during Ottawa's dry winter months when indoor humidity drops to 15-20 percent, making even fine particles more likely to scratch glass surfaces during cleaning attempts. Clay-rich soil tracked in from job sites creates particularly abrasive particles that can scratch glass if not properly removed before window cleaning begins.

Glass repair specialists in the Ottawa area can sometimes polish out very light surface scratches using specialized compounds and equipment, but this service typically costs $150-400 per window depending on the size and severity of scratching. Deep scratches, chips, or cracks require complete glass replacement, which runs $200-800 per window for standard residential sizes. The Ontario Building Code requires that any glass replacement in habitable areas meet current safety standards, which may mean upgrading to tempered or laminated glass even if the original was standard annealed glass.

The best approach is prevention during construction — ensure contractors properly protect windows with appropriate film or boards, and verify that your post-construction cleaning team uses clean cloths and proper glass-cleaning techniques. When hiring cleaning professionals, confirm they understand the difference between cleaning glass and repairing it, and ask about their insurance coverage for accidental glass damage during cleaning.
