WinDor has been manufacturing replacement windows and doors in Southern California for over 27 years years.  And in that time, we have been operated by the same family, we have used the same name, and we use the same contractors license number.

We'll Be Here For You

So many other window and door companies have gone out of business or changed their name every few years to avoid the ongoing customer service costs and warranty issues.  We haven't!  Our commitment to quality over quantity allows us to continue on the right way.

Factory Direct Savings

When you buy replacement windows and doors from WinDor, you are buying directly from the manufacturer.  Our prices are competitive to other high-end windows and we put some of the savings back into building better quality products.

Eliminate the Middle-Man

There is no middle-men adding 10% here and another 15% there.  We sell them, we make them, we install them and most importantly, we service and warranty them.  You'll never be put in between a contractor or manufacturer pointing fingers at each other as to who needs to solve your window or door problems.

Commitment to Quality

Being the window and door manufacturer, and the sales organization also has its advantages when it comes to quality.  What we save by eliminating layers allows us to invest more money into our windows and doors.

Will you be next?

WinDor uses only the finest vinyl available, the best glass, stainless steel rollers instead of plastic or brass that break or gunk up.  Our hardware is also great!

Commitment to Service

We're proud of our BBB A+ rating.  For nearly two decades we've been recognized as one of the the best window and door companies by AngiesList, the OC Register and others.  Nothing makes us happier than doing well for our clients.

The Ongoing Relationship

We understand that the bond and commitment that we create with our clients starts when you sign the contract - but continues on through your warranty period.  It doesn't end after we cash your check.

Family Owned and Operated

WinDor was founded in Orange County California by the same people who own and operate it today.  We are passionate about replacement windows and doors.  Our children are also very much involved in the day-to-day opperations and continuing this rich tradition.

Pride in the Company

The legacy of WinDor is important to everyone involved, from the owners to their family members who have been brought up in the business.  But it doesn't stop there. Many of our team have been with the company for over 25 years!
