FREQUENTLY ASKED QUESTIONS

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."
