Mr. and Mrs. Russell GordonHomeowner

Excellent Contractor Skills

We would like to thank you for the great job that you and your employees did in installing the new windows and sliding doors in our home. The installation was done in a very professional manner and the two bay windows look like they were put in the same time the house was built. Your overall excellent contractor skills are evident in your work.

Hugh and Joanne ArmstrongHomeowner

Perfect Match

We are very pleased with our new Superior Windows. We are especially pleased with the restucco. You matched the texture and color to the existing stucco perfectly.

Sam & CarolHomeowner

Outstanding Work

We just wanted to say THANK YOU to everyone for doing such a great job on installing our 16 foot French sliding door, 96" picture window, and 48" double hung window. The eight foot opening on our French slider is awesome!!

Great Features

I like my windows - the appearance, the fit, the features such as safety locks, and the provision to wash the outside from the inside.

Art KochmanHomeowner

Excellent Service

I wish to express my sincere thanks for such a great job you have recently done in installing 14 windows plus two 8' sliding doors at our house. The contract was drafted and signed shortly after we gave Mike the details of what we wanted. The price Mike quoted beat the others we looked at earlier. I felt the deal was done in a professional and practical manner with no wasted time.

Sancy WuHomeowner

Clifferd R. HelwigHomeowner

Outstanding Teamwork

I must say that I have dealt with many contractors during my working life, but never had I seen such teamwork as your people. The work was done in a top notch professional manner, very knowledgeable, effective, timely, and extremely clean and to say the least just a group of hard working guys.

Louise PerazaHomeowner

Significant Difference

Just a note to let you know how great our new windows are. By putting those windows in, we lowered the temperature in our loft by 12-15 degrees. What a difference! I also wanted to thank you for the prompt service. It's nice to see the quality work of the past still being done.

Ann & Gabe RamirezHomeowner

Beautiful Patio Work

We love the way the cement patio was done. Several of our neighbors have given compliments since. It looks great! We are completely and totally impressed with the quality of work put into it.

Julie & Bill HinkleyHomeowner

Easy to Work With

Mike was easy to work with and fair when it came to problems as the work progressed. He also followed up well when problems occurred with subcontractor's work. I would recommend Mike for any home remodeling that you may need.

Ed PetuckaHomeowner

Complete Success

The installation was fast, clearly professional and we were most favorably impressed when we noted the frequent use of a portable vacuum to pick up the debris left from the removal of each aluminum window. Our experience with California Doors and Windows was a complete success.

Mr. & Mrs. J. L. WingertHomeowner

Light and Bright

I am very pleased with the windows you installed. The rooms are so much lighter and brighter and cooler too in this heat. I no longer have to be concerned about fading color in rugs and furniture. Since I moved here a year ago, I've make numerous improvements but the new windows have added the most in comfort and attractiveness.

Jeanne KresslerHomeowner

Professional Crew

Every crew member was cooperative and performed in a professional manner. I especially appreciated the thorough clean up upon completion of the patio.

Winston B. WhittemoreHomeowner

Wonderful Work

I wanted to thank you and your staff for the wonderful work you did on our door installation. Your work and service was very professional, I would gladly recommend you to any of my friends.

The pictures cannot illustrate the beauty and craftsmanship that we enjoy everyday thanks to your service.

Efficient and Timely

My husband and I would like to thank you and your Father for the wonderful job you did converting our master bedroom retreat into a bedroom for our new baby. The job was done in an efficient and timely manner with minimal disruption to our family. The end result was a nice addition to our home.

Deborah F. BoiceHomeowner

Your work was done in a timely and efficient manner. You were prompt in returning calls, showing up for appointments and your installers were most courteous. All in all, we couldn't have been more pleased once the job was completed.

Amazing Service

The service I received from your company was amazing. I have worked with many contractors, but working with your Company was the best experience.

Spencer PabloHomeowner

Heat and UV Protection

Although I bought the windows primarily for the heat and UV protection, I am even more thrilled with their appearance. The quality of the product is excellent. Even with the hot summer we've had, the windows have cut down the interior heat quite a bit. I would certainly recommend these windows and your company to my friends and neighbors.

Elayne P BendelHomeowner

Prompt and Professional

I recently had California Doors and Windows plan and install a patio door in my Banker's Hill condo. I highly appreciated the work, beginning with arriving promptly for the estimate, measuring, and ordering of the door which was delivered exactly as planned.

Patricia LindquistHomeowner

Beautiful and Clean
