California Window & Exteriors, Inc., is your best choice for all of your home improvement needs. My name is Jeffery Petty and I am the owner of the company. I have been in business for over 15 years while carrying my same installer since 1998. Please look at my reviews as I have over 150 with a very high rating which shows longevity and quality.

"I am generally a DIY'r and a while back I purchased six modern windows from a big box store to replace the original aluminum windows in my sixty year old home. I had planned to install them myself with the help of my grandson and we had gotten one installed when he got a job offer, out of state, which he could not pass up. These windows were too heavy and bulky for me to handle myself and my search for an installer happily brought me to Jeff Petty and CW&E. Jeff's crew arrived on time, were polite, clean and efficient and except for a short lunch break, worked straight through to completion. There were no surprises with the price and my family and I are very happy with the results of their work. Whenever I might need help with a similar project, I will call CW&E again."

"American Home Renewal recently replaced 7 double hung windows in our home. We had 3 window replacement companies come to our home discuss the process and give us estimates. Chris from American Home Renewal was by far the most professional. He spent time with us, accurately described the entire installation process with us and exhibited willingness and patience to hear and understand what we were looking for in the new windows. The American Home Renewal contract was clear, concise and straight forward. The 3 day installation process was fluid and fairly quiet and we were able to work from home. It had a minimal impact on our lives. The crew cleaned up thoroughly every day and took time to make sure we knew how to tilt the windows for eventual cleaning etc. Keith, the Production Manager, checked in a few times during the 3 day installation period to ensure everything was progressing to our satisfaction. We could not be more pleased with American Home Renewal's level of professional service and care."

Glass Block Windows questions, answered by experts

Costs depend on wall size, labor, block type, and customizations like frosted or colored glass.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

Glass blocks provide privacy, natural light diffusion, insulation, and a decorative aesthetic.

Glass blocks are much thicker than glass panes in traditional windows and serve as better insulators. The overall glass block window is sealed against drafts that allow warm or cool air to escape, saving on energy costs. Since this type of window is sealed airtight into your home, you don’t have to worry about air leaks and drafts as often as traditional windows that open and close. When installing glass block windows, look for options that are Energy Star rated, proving their energy efficiency.

Options include tempered, laminated, and tinted glass for various needs.
