FREQUENTLY ASKED QUESTIONS

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 clients say:


"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 has much better curb appeal. Would thoroughly recommend Windtek!"

 

Mark Reeves


"Just had some windows replaced and was very impressed with both the sales and installation services. Ryan was very professional and informative — he even showed up the day of installation to ensure we were happy with the work being done. Will definitely contact Windtek in the future for window/door replacements."

 

James McCan


"We needed a custom window for our kitchen — it needed light so badly, but the shape was awkward. Windtek did an amazing job of taking measurements and having a high-quality, energy efficient, custom window installed in our home. Absolutely stunning."
