What Our Clients Say

Sandra V

Had a great experience with everyone at eco choice. Friendly and professional. Love how my new windows and door look.

 

Matt

From the get-go Terry, the sales rep, was professional and easy to work with. He priced the job competitively with a superior energy star product. Then the install team took over and their workmanship was phenomenal. They took care of the floors, covered the furniture and cleaned up after themselves. Considering the amount of work that was completed in just 2 days the team amazed me with their detail oriented approach. Thanks Eco Choice - I likely will be calling you for my Doors next!

I chose two different window companies to do various windows in my home as I liked certain features of each window type. As it turns out, Eco Choice was by far the better company from my experience. If you want a professional window and door company, this would be the one. No wonder they have won multiple awards. Thank you Alani and team.

By all accounts, they did a terrific job as our doors work beautifully and look great! We would highly recommend using EcoChoice and plan to use them again for future projects.
