Frequently Asked Questions
What our Customers are Saying
I just signed a contract for windows with Apex. The in-home experience and quality of windows sold me on working with Apex. My salesperson, Justin, was very professional and personable. He made my feel comfortable about this large purchase and had a thoughtful answer to all of my questions. My windows are very old in my over 100 yr old house and I'm very much looking forward to seeing the final product. I'm also looking forward the my energy bill going down. Thank you Justin for all your time and patience explaining the whole process to me.
Ericka
I have had a few different companies come to provide quotes for new windows, Justin Hill with Apex was by far the best presentation/experience that I have had! He was very knowledgeable, and was able to answer all of my questions. I also appreciated his no pressure approach, I could tell he was invested in making sure I had the education to make an informed decision without pressuring me to buy. I also liked that he was transparent and came in with the best quote possible at the beginning, I didn't have to play a game of negotiation.
Shano
I am so glad I answered my door!!! I feel like we all have that terrible feeling of "who's at my door now"...In this case, it was Justin from Apex Energy Solutions. From the start, he was personable and professional. When we scheduled our appointment to discuss windows, my husband and I were blown away with the quality of Insignia, their installation standards, and the no pressure environment. We were so excited with the value, we jumped at the opportunity, and waited about 4 months. It was worth the wait because we slept great!!! The comfortability of our home immediately after install was noticeable.

Justin is one of the most honest and trustworthy humans I know. Not only that but he keeps his word and gets the job done. He’ll make sure that you get exactly what you need and figure out the most cost effective way to do it for you. I always recommend JTs Windows to anyone in the market for new windows or an upgrade!

Everything was first class service, from the initial consultation, to the communication and the installation, and even a follow-up the day of install with the original sales consultant. The windows are amazing - such a great upgrade!
