Doors That Close, Windows That Seal, Locks That Turn

Same-Day Door & Lock Service in Thornhill

Our Journey

How a Repair Crew Became an Installation Company

The transition took years and a lot of certification. Here is roughly how it went.

2010

Repairs Only

A two-person outfit doing draught-proofing and hardware work on older residential windows.

2014

Licensed for Installation

Certification from the manufacturers we knew best let us start fitting complete units.

2019

A Real Team

Trained technicians joined and the service area grew to cover communities across the region.

Today

Full Service, Same Ethos

Doors, windows, glass, and locks under one roof, run with the same hands-on approach.

Our Commitment

Built on Careful Work and Straight Answers

Owners across Thornhill keep calling Windows & Doors Thornhill because a squeaky hinge gets the same attention as a full door replacement. Quick adjustment or emergency board-up, the method does not change: look properly, explain plainly, then do work that holds.

  • Security Checked Every Visit: Locks, frames, and seals get tested while we are there, so the property leaves safer than repaired alone.
  • Doors, Windows, and Glass Together: Entry doors, patio sliders, storefront glazing, and every window style, all handled by one crew.
  • Locks and Access Control Included: Rekeying a single deadbolt or wiring controlled entry across a site, we cover the hardware behind the hardware.
  • Materials Chosen for the Job: Components rated for daily use and real weather, not for looking acceptable on handover day.
  • Answers Before Any Work Starts: What failed, what it takes to put right, and what it costs, all settled before a tool comes out.
  • Inspections That Catch It Early: Scheduled checks find tired seals and drifting hardware while they are still cheap to correct.

What We Stand For

Windows and doors are more than design features — they’re structural elements that protect what matters most. That’s why we stand for:

  • Premium materials: durable, weather-resistant products built to last.
