Great experience. Had a small imperfection in a couple pieces of the stone and the installer said he wasnâ t attaching his name to it. Took it back and recut it. They even had it reinstalled first thing the next morning. Will use them again for our bathroom remodel.

The install went great. Very quick and kept us in the loop. Had an issue after the install and getting someone to fix the issue was rather difficult as the person I talked to was quite dodgy and short with me. Would not respond to calls and kept missing self imposed deadlines to get back to me....

Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”
