We at Windtek manufacturer and install a wide variety of windows and door products. Here is how we breakdown where we help:

  • Doors: Entrance, Patio, Storm, garage doors
  • Windows: Replacements, Bay, Bow, End-Vent, single hung, single slider, double hung, double slider, awning window and casement windows
  • We do NOT offer interior doors

Depending on your home and existing windows or doors, there are two common forms of installation:


  • Retrofit: Working inside the existing frame, not removing brick or materials.

  • Brick-To-Brick: We take the whole frame out and re-do the frame and section of the wall

Unlike a pro-rated warranty which decreases in value overtime. Our products come with a full non pro-rated warranty for the lifetime of the product. Our warranty is also transferable.

Yes, Windtek stays competitive with industry standard prices. We can offer our customers factory-direct pricing. We focus on quality and price accordingly to our high standards. We even offer bulk pricing. Customers who order in large quantities or purchasing multiple products will receive a discount. Please talk with your Windtek contact for more information.

Most of our products qualify homeowners with a home renovation rebate. Customers can contact Barrier Science Group to submit your recent project: https://www.barriersciences.com/ 

We make all our windows and door products ourselves. As such we engineer them with features like slider tilts for our windows that make them easier to clean then traditional windows or doors.

Contractors often get preferential pricing from window manufacturers. Yet while they may get a cheaper price than you will, the high fees for labor far outstrip any money you'll save by having a contractor order your replacement windows. The job becomes much cheaper when you don't have to pay for a window installer.

Installing new home windows are definitely worth the investment depending on what you are looking to get from them. Replacement windows bring value by increasing your home's resale value, increasing energy efficiency and increase your home's overall aesthetics.

Not always, but it depends on the door you choose. The average front door cost is $2,500 (single door, excluding sidelight), with a range from $1,500, for the most basic and budget-friendly options, to over $5,000, for more upscale exterior doors.

What our customers have to say about our work


Love my new windows and storm door. I highly recommend Windtek. From initial consult to installation  Ryan had my back, all questions and concerns answered and all window updates initiated by him, never had to chase anybody down. Great windows and excellent customer service. Windtek also offers a large variety of window options and colours inside and out at a great price point. They are  the manufacturer, everything is custom. Roman and Ali, the installers were an amazing duo. Installed all windows  quickly and with care. Job well done.

Mohsan Abdullah

Windtek was exactly what I was looking for when it came to replacing my windows. Not only did they inform me about what the current regulations for essential and non essential window replacements were during this pandemic, they guided me to the exact product I needed for my house. I have many more windows that I will replace in the future and know that I will only be calling Windtek.

Brianna Carney

We are very pleased with our new windows and door that we purchased from Windtek Windows & Doors. We had a great experience working with the Windtek team and the owner Danny. They are professional and true window experts. We will be referring them to all our friends and family!

Adam Merchant

Danny was a window professional of the highest order! I like it when businesses educate consumers about all products and don't try to sell you something specific. Danny made me feel that my input was the most important.  Bravo! Will definitely recommend them to my friends.

Shahrokh Aryan

Best price, good quality, fast delivery, no unpleasant surprises. I will use them again and recommend them.

Mark Reeves

Danny and his crew were exceptional at meeting our needs. Gave a very fair quote and installed and cleaned up extremely well. I now know that my house had a much better curb appeal. Would thoroughly recommend Windtek!
