Some wood and vinyl window designs haven’t changed, but the energy efficiency of them has. No matter how you want the job done, we’re here to serve.

Here are a few popular window styles:

Awning Windows

Awning windows have hinges at the top and open outward. They provide a benefit to the homeowner with their wide design leaving a side-to-side amount of ventilation. They are often placed above or below other windows to add light and ventilation to a room.


Bay Windows

Bay windows are windows that project outward from the home. They also provide ventilation from each side with your choice of either a casement or double hung style.


Casement Windows

Casement Windows have hinges on the sides and open with just a turn of a handle located at the bottom of the window. Most of the time they are taller than wide and provide excellent ventilation especially for hard to reach places.


Double Hung Windows

Double hung windows were originally often fitted with shutters. They slide up or down to provide ventilation. They have two sashes in a single frame and are a great option for any room in the house.

    Extremely fast response and service. Highly recommend! The price was reasonable along with financing options. I bought a house this year without a roof inspection (Biggest L of the year), but this team was able to replace the entire flat roof in one day. So happy that I don't have to deal with any more leaks!

    By the time I connected with Certified, I had already gone through at least 3-4 window presentations. If your not familiar with the process, it's mostly full of high pressure sales tactics and overprices proposals. The folks at Certified did not take the approach. The owner of the company came out to do the survey. His approach was simple: we will provide you with quality windows at a fair price and customer service to ensure your satisfied.
    Certified delivered on all of these. Their pricing 20% to 50% less than anything we had received from the big name companies. The windows arrived earlier than expected, so the job was completed sooner than we were initially told. Quality of the windows is great and I trust that if we have any warranty issues that Certified will hold up their end of the deal. We had a few workmanship issues (mostly caulking) that we didn't catch right away, but when this was pointed out to their team, they quickly sent someone out to check it out, and a crew was out the following day to make the repairs.
    Overall a great experience. Big thanks to Tom, Diane, Koo, and The Crew.
