Apex Insignia Windows Quote
| Window Series | Total Quote Installed | Average Installed Cost | Editor Recommendation |
|---|---|---|---|
| Champion Vinyl | $31,800 | $1,272 | Best Option |
| Apex Insignia | $27,500 | $1,100 | Decent Window, But Not First Choice |
| Pella 250 Vinyl | $38,300 | $1,532 | Highest Bid |
"We're in Kansis City have taken your advice and gotten a few bids around town. We had a Pella Windows Cost Bid: $38,300 on a 250 vinyl window, an Apex quote for $27,500 on an Insignia window and a Champion Windows Prices Quote: $31,800 on one of their vinyl windows (not sure the model). We have I believe 25 windows that need replacing."

Editor's Advice:
Mandy, the Champion quote would be my choice. Probably not the Apex, although they make a decent vinyl window. The Champion is better in my opinion (both companies owned by Great Day Improvements).

Colorado Replacement Windows
| Window Brand | Installation Method | Editor Takeaway |
|---|---|---|
| Renewal by Andersen | Full Frame Replacement | Worth Comparing With Additional Bids |
| Apex Insignia | Insert Installation | Recommended Brand; Now Uses Champion Windows |
"Hi, I live at 7300 ft in Colorado and was curious of your recommended list of window types. Currently, we have quotes from Renewal by Anderson and Apex Insignia. Anderson recommended the full frame replacement method and Apex went with the less expensive insert based installation method in their quotes.
However, we are going with dark bronze exterior option with white interior and want to replace trim on interior to refresh the look. The current windows are 35 years old and there are some places where replacing blocking seems warranted because of damage and rot. So, any advice on window brands and install methods would be appreciated! Thanks!"

Editor's Advice:
Brian, here are my Colorado recommendations: (my advise would be to collect enough free bids to feel confident in terms of whether full frame or insert installation is the best option based on the differing opinions of the companies...) Sometimes, it's a tricky one to answer, but hopefully you will get there! I do like Apex Energy Solutions though and certainly think it is worth a bid. Lately, they have been using Champion windows, which is a step up from the Alside windows that they were using prior to this.

Stanek Window Issues
| Warranty Service | Total Cost | Average Cost Per Window |
|---|---|---|
| Initial Repair Quote | Not Provided | $100 |
| Final Repair Cost | Not Provided | $75 |
"We replaced our windows with a local company using Stanek about 7 years ago and now the coating on several of the windows is coming off. The company is now owned by Great Day Improvements and they want to charge us $100 per window to repair the problem. Does that seem like a fair price?"
Marilyne - Homeowner - from 2022
Editor's Advice:
Marilyne, it certainly depends on whether the windows are still under warranty. Some of those exterior coatings don't carry a very long warranty. I'd call them up again and have them clarify - I can find you the number that should get you to an actual person (hopefully).

Homeowner Follow-Up:
"Tim, I took your advice and called up Great Day and they were nice enough to charge me $75 only to come out and replace the coatings and repair a broken seal on one other of the windows. The installers were very good, did the work, cleaned up, and were quite nice. I was pleasantly surprised by how well it all worked out and wanted to thank you for your advice. It's nice to have an actual person to help me out with this process. Is there someway that I can pay you for all of your help?!"
Marilyne - Homeowner - from 2022
Final Editor Response:
Marilyn, no payment necessary, glad to help out. If you find yourself on reddit reading about replacement windows, I would love a shout out and link to our site. Referrals are always appreciated. Additionally, I'm happy to hear about Great Day and how they took care of their responsibility to you. Unfortunately, this is not always the case with many companies in the window and door space.
