“I am very satisfied with the repair of my window from the on start. The call taker, Ira, was pleasant and accommodating providing me with information and a quick appointment. The tech, Alex, demonstrated professionalism. He was prompt and efficient. The repair was completed in a timely fashion. I would recommend this company for any repairs especially with Alex.”

“I called Build and Fix when I found that I could not open my back French doors this Spring! One side had dropped down considerably. I called and Max came over to look at the situation . It required taking the doors off and re-positioning them. We booked a convenient time and he came over virtually at the end of the day due to a longer spot before me but he stayed, completed the job even though it was 7:30 when he left. He was professional, cheerful and left the site immaculate. Mary at the front desk was my go to with questions and she too was always both helpful and on top of things. Communication with them was terrific. You never waited. The job was done definitely to my satisfaction. The price was reasonable . I’d definitely recommend using them for your needs!!!!”

“Great company … excellent work repairing my door . The problem with the door was an interior bolt so a picture wouldn’t show anything .. but it was not an easy fix … all was done in a timely and skilled fashion! My building is located in Scarborough. The door was a commercial fire exit door. Repair wait time 1–2 hr”

“Excellent and incredibly fast service! My door that needed urgent attention, and they responded immediately. The technician arrived quickly within an hour. The pricing was very fair for such a rapid turnaround. I highly recommend them for any urgent glass repair needs!”

Newmarket's downtown core along Main Street is one of the older commercial strips north of Toronto, lined with century-old brick storefronts above newer residential infill. Alongside those historic buildings sit postwar and 1980s subdivisions where original sliding doors and single-pane windows are common repair calls.
