A Window Company Dedicated to Quality

We are a window company that recognizes the importance of having high-performance windows in place, which is why we source our products from industry-leading manufacturers, such as MI Windows & Doors and ProVia.

These companies are known for constructing energy-efficient windows that are equipped with:

  • Gas fills between multiple panes of glass
  • uPVC frames filled with polyurethane insulating foam
  • Stainless-steel spacers with moisture-absorbing desiccant beads
  • Low-E glass coatings
  • Triple weatherstripping

Having energy-efficient windows installed on your home is a smart choice, as they can help reduce stress on your HVAC system, which may even lower your monthly energy expenses.

What’s more, we are a window company that also values the importance of aesthetics. Considering this, we offer replacement windows in a wide selection of popular styles, including:

  • Double-hung
  • Single-hung
  • Casement
  • Sliding
  • Awning
  • Bay and bow
  • Garden
  • Geometric
  • Hopper
  • Picture

Customization options are available as well, so you can choose your desired frame color or finish, grid pattern, decorative glass design, and hardware.

“Once again, The Door Store installed a door and frame to perfection. This was done in 25 degree weather. Four windows installed this past summer on a ninety year old house. We have used David and his excellent installers for years. I would not go to any other place of business for my doors and windows plus beautiful hardware.”

“Recently our home in Berkeley received vinyl replacement windows, a bow window and steel doors. I wish to write a big thank you to the gentlemen who installed the above improvements. The windows and doors look beautiful. The men were enjoyable to have around. They tolerated our questions and our neighbor's questions with genuine concern and patience. Paul and I appreciate their high quality of workmanship. Thank you for a job well done.”
