Opening a window after the frost caused damage, and during the extreme cold we urgently needed a quick repair. The team was attentive, responsive, and very reliable. Paul was very understanding about our situation and the time-sensitive nature of the repair. Keegan was able to schedule us quickly and was very attentive throughout the process.

We’re especially happy to support a local business — and it’s no surprise they have so many outstanding reviews. The service was professional, efficient, and handled with great care.

Highly recommended!

We recently had the Window Repair Guys complete a window installation at our home and couldn’t be more pleased with the entire experience. From the initial consultation to the final cleanup, everything was handled with professionalism and attention to detail.
Paul (the owner) was knowledgeable, responsive, and a pleasure to work with throughout the process. His installers, Keegan and Jake, were equally impressive — courteous, respectful, and clearly take pride in their work. They arrived on time, worked efficiently, maintained a clean workspace, and ensured every question we had was answered.
It’s refreshing to see young tradesmen who are both skilled and professional. Paul is fortunate to have such outstanding team members representing his company. We wouldn’t hesitate to recommend the Window Repair Guys to anyone looking for quality workmanship and excellent customer service.

Very happy with the whole process from the initial email to final purchase. I was concerned about replacing my front window...it is a large window and heard the cost would be high but not with Window Repair Guys...like they were able to just replace the glass. The install went very smoothly and the guys were very friendly. Will definitely use them again and have recommended them to many. The first picture is before...2nd is after. Big difference.

We received excellent service at a really good price. Their service estimator promptly responded with a cost estimate for the repair of 2 broken windows. It only took 2 weeks from the day we booked the repair for the service to be completed. Their Service Team arrived on time, completed the job, cleaned up after themselves and were done before I new it. I have already recommended their quality service to friends and would encourage anyone looking for a cost effective solution to their window issues, to use the Window Repair Guys. Job well done by an excellent Canadian Company.

Frequently Asked Questions

In many cases the insulated glass unit (IGU) can be replaced without changing the entire frame. The team measures the opening, orders a matching sealed unit, and installs it once ready. This approach can restore clarity and efficiency when the frame is still in good condition.

After measurements, most projects require a lead time for the new sealed unit to be fabricated. Installation itself is commonly completed in a single visit and is usually finished the same day. Timelines vary by size, glass type, and supplier availability.

Yes, common hardware components can often be repaired or replaced. During the assessment, technicians identify the specific parts and determine if repair is feasible or if a replacement is required. Recommendations are provided with clear pricing before work proceeds.

Photos of the window, approximate measurements, and a brief description of the issue are useful. If possible, include the window brand or any labels on the spacer. This helps provide a faster and more accurate estimate.

Yes, installers remove debris and vacuum the work area as needed. Protective drop cloths are used where appropriate to help keep interiors clean. The goal is to leave the space tidy after the repair or replacement.
