Replaced all my windows with Earthwise windows by Home Guard. Love them. Reduced outside noise. Reduced my energy costs. So much easier to open and close. Love them.

I’ve had my new earthwise of Indiana windows now for five months, and I cannot believe how much better my house felt this winter compared to my old windows. The installer did a great job putting them in and left no mess. The windows are incredible. I can’t wait to get the rest of my windows in the back of the house replaced with these windows.

Purchased new windows a month ago. I got the black in and black out casement, they are stunning! My neighbors are jealous!

Earthwise Windows stand out as a remarkable product, offering not only superb craftsmanship but also unparalleled performance. Their ability to create a tight seal against airflow and cold drafts during the winter months ensures a cozy and energy-efficient home environment. Moreover, come summertime, these windows excel at preserving the cool air generated by expensive air conditioning systems, effectively keeping indoor spaces refreshingly comfortable without overworking your HVAC unit. With Earthwise Windows, you're not just investing in quality; you're investing in year-round comfort and energy savings for your home.

When we moved into our house about 10 years ago the previous homeowner purchased the Earthwise windows by Home Guard. I can't say enough great things about these windows. Since we have moved in, we have not had any issues and they are so easy to clean. We have an addition on our home and we will be purchasing Homeguard windows for that room.
