20 years ago I built my house using Mercer double-pane windows, which included a lifetime warranty. I've had some seals leak which causes the windows to fog up, but Mercer honored the warranty by replacing the fogged windows.

Recently several windows fogged up. I found that VPI took over Mercer in 2014. I contacted Brianna at VPI about two very large windows with seal issues; Jim and Brandon just completed the replacement.

If you are looking for a hassle-free window company that honors "life-time warranties", you can count on VPI!
