What Our Homeowners Say About Us
Rated 4.9 out of 5 from 62 Google reviews
Why Homeowners Choose Anderson
We're not the biggest window and door company in the Bay Area. We don't try to be. What we do is show up with our own employees, install products we stand behind, and have the owner check the finished work before we leave your house.
Most companies around here sub out their labor to whoever's available that week. You never know who's actually doing the work. At Anderson, every installer is a full-time employee trained on Andersen and Milgard product lines. John, the owner, personally oversees projects from the initial measurement to the final walkthrough.
That approach has kept us in business for 25 years and 225,000 installations. San Jose, Sunnyvale, Mountain View, Palo Alto, Los Gatos, Cupertino, Santa Clara, Campbell, Morgan Hill, Saratoga, Milpitas, Gilroy. If you're in the county, we've probably already done work on your street.
Window Replacement
for Santa Clara County Homes
Old windows don't just look bad. They leak conditioned air 24 hours a day. Your HVAC runs longer, your bills climb higher, and your home never quite feels comfortable. The longer you wait, the more you spend on energy you're losing through the glass.
We replace every type of residential window: single-hung, double-hung, casement, awning, sliding, picture, bay, and bow. Custom shapes and sizes too.
Andersen and Milgard Windows
Every window we install comes from Andersen or Milgard. Both are built for Bay Area conditions and backed by full manufacturer warranties on top of our own lifetime installation warranty. You're covered from every angle.
Signs You Need New Windows
Drafts around the frame.
Condensation trapped between panes.
Windows that stick, rattle, or won't lock.
Energy bills that keep climbing.
If any of those sound familiar, patching won't fix it. The window has failed. Replacing it will.
Door Replacement
for Santa Clara County Homes
A front door that doesn't seal properly lets in noise, dust, and outside air. It also tells every visitor your home is overdue for an upgrade. Replacing it changes how your home feels inside and how it looks from the street.
We replace front doors, entry doors, patio doors, French doors, sliding glass doors, and interior doors. Wood, fiberglass, and vinyl, depending on the application.
Simpson, Andersen, and Milgard Doors
Simpson Door Company has been building wood doors for over 100 years. For curb appeal and lasting build quality, they're hard to beat. For fiberglass and vinyl, we turn to Andersen and Milgard. Every door carries a manufacturer warranty plus our lifetime installation guarantee.
How Door Replacement Works
We measure your opening precisely, order to spec, and install it so it seals tight from day one. One visit. No callbacks. No gaps.
STILL HAVE Questions?
Window and Door Replacement FAQs
How long does a window or door replacement take?
Most single-family projects finish in 1-2 days. Larger homes or full-house replacements may take 3-5 days. We'll give you a clear timeline before we start.
What brands do you install?
We're certified dealers for Andersen Windows and Doors, Milgard Windows and Doors, and Simpson Door Company.
Do I need to replace all my windows at once?
No. Many homeowners do it in phases. That said, replacing multiple windows in one visit is more cost-effective than scheduling separate trips.
How do I know it's time for new windows?
Drafty rooms, condensation between glass panes, difficulty opening or closing, and higher energy bills are the most common signs.
What areas do you serve?
All of Santa Clara County. San Jose, Santa Clara, Sunnyvale, Mountain View, Palo Alto, Los Gatos, Cupertino, Campbell, Saratoga, Milpitas, Morgan Hill, and Gilroy.
Do you offer free estimates?
Yes. The owner John or a senior team member comes to your home, takes measurements, and walks you through your options. No obligation.

I had a great experience with Anderson Window and Door. We had purchased a large trifold outside door and two regular outside doors. They came and made very careful measurements, ordered the doors, which arrived sooner than expected, and did a smooth installation. They have been in and working well for over a year now. I will definitely contact them again if I need another new door or window.

John was fantastic and answered all questions, while helping me pick the right sliding doors for all 3 locations. All they do is the door installation so I had plenty of work to do before and after the doors were installed. I'm cheap so I did the prep and finish myself. They came in and installed all doors in 3 days. They trimmed and cased them inside and out and were done. He then came by for final payment while we shared a nice bottle of Cabernet. All is good.
