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."

"Had Red come out to do some small concrete work at the front of my driveway. He did a solid job?work looks clean, held up well, and he knocked it out in good time. Communication was straightforward and he was easy to work with. Only reason I?m giving 4 stars instead of 5 is there?s always room for little improvements, but overall I?m happy with the job and would call him again. "

RC&G is an acronym - it stands for "Richard, Charlene, and the Girls", because it's a great reminder of what I'm working for. I'm Richard and my wife and daughters are the most important thing in the world to me. Also hugely important to me is doing great work in my business as a handyman. I've always been mechanically inclined and good at fixing whatever's broken. With decades of experience, now I'm truly a master handyman. Whatever you need, I'm here to get it done. I respond quickly to contacts and give an accurate estimate. Then I arrive as scheduled, do the job right, and leave your house as clean as I found it. I'm looking forward to meeting you!

"Richard was friendly and kind. He installed our blinds, helped clear our sink, fixed our screen door, and assessed our TV mount— all in an hour. We’d love to work with RC&G. As someone with mini houses fixes and projects it can be intimidating to ask for help, but RC&G showed us most things are fixable. "

Windows questions, answered by experts

Yes, most manufacturers and installers offer warranties. Confirm terms before purchasing.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

Because bay windows are a combination of three windows, there are many options for how wide or tall they can be. That said, individual windows come in standard sizes, and you can use those as a guide for the width and height of your bay window.

It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.

The best way to clean outside windows is by using a garden hose. Start by spraying the windows with a high-pressure stream to clear off loose dirt and grime. Then use a mixture of hot water and dish soap and scrub the windows with a sponge. Rinse off the soapy water with the hose. Before you finish up, spray the windows with a solution of vinegar and water and wipe them down with a microfiber cloth.
