"Working with Wasco was a great experience all around, both sales and installation. We intend to use them again in the future to replace additional windows. They were incredibly knowledgable and professional. We would rate them an A++"

"I had received parts from the window manufacturer that, of course, were completely wrong for the window. They examined and tested the window and were able to make the necessary adjustments so that the window closed snuggly to eliminate the draftiness. Arrived on time and were very personable and explained some additional options. I will definitely call them again for any future window repairs and will recommend them to others."

"Mr Atkins was very knowledgeable about the windows that he was selling, very friendly. Mr Atkins was not pushing me to buy the windows which I like. Once again thank you for your professionalism. I look forward to getting my new windows installed! Kelly"

Windows questions, answered by experts

The cost of window installation depends on several factors, including the window type, size, and frame material. Labor rates, the need for custom sizing, and any required structural modifications will also influence the final price.

It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.

The key difference between a hung window and an awning window is that hung windows (including single-hung and double-hung versions) slide vertically to open and close. In contrast, awning windows have a hinge at the top and open outward at an angle. You can use both types of windows throughout your home, but awning windows are best suited for kitchens and bathrooms.

Window replacement is typically always worth the cost, both from a money-saving standpoint and a comfort standpoint. If your windows are older and significantly damaged, a window replacement can actually save you money in the long term by improving energy efficiency. If your windows aren’t up to code, you may not really have a choice. 

Yes, they address underlying issues, providing long-term seals and energy savings you might need help to achieve.
