    I had Artur come and replace and install my basement double French patio doors, and I’m very happy with the work. He was clear about everything from the start, arrived on time, and did a great job with the installation.

    We replaced 12 windows and 1 sliding door in my parents’ house in Oakville based on a neighbor’s recommendation. Thanks to Max for the careful and meticulous work with the interior wood trim.

    Got 2 external doors replaced with new ones. Artur and his cousin did an excellent job with minimum fuss. Very patient in answering all the questions about the project.

What window and door replacement costs

Starting prices for the most common jobs in Toronto and the GTA. Each one includes installation and taking away the old unit.

What changes the price

  • Size and number of openings. Small, medium and large windows each have their own starting price, whether casement, slider, hung or picture.
  • Glass. Double or triple glazing. Triple is priced by configuration.
  • How it opens. Casement, awning, slider, hung or a fixed picture window.
  • The wall around it. Brick, stucco, siding work or a larger opening is priced after we see it.
  • One order for windows and doors. Up to 50% off the installation.

Honestly, the quality is better than that of companies charging much higher prices.

Installation from A to Z

One price for the whole job. After a standard install, the most you may want to do is paint the interior trim.

  • Old windows or doors taken out
  • Haul-away of everything we remove
  • New unit installed and sealed by our crew
  • Exterior capping
  • Interior casing

Priced separately, after we see it: brick, stucco or a larger opening, and new siding, soffit or decorative trim boxes.
