FAQ

Door Questions, Answered

What affects the cost of a new door?

Door cost depends on the type of door, its size, frame material, glass package, hardware, and whether the opening needs to be resized or reframed. A standard replacement in an existing opening costs less than a new or widened opening. We measure at your home and give you a free written estimate.

How long does a typical door installation take?

Most door installations are completed in a single day once the door arrives. Doors are built to the size of your opening after we measure, which is the longest part of the timeline. Larger openings or projects with structural work can take longer, and we give you a clear schedule up front.

Do I need a permit for a new door?

Many exterior door replacements need a permit, especially when the opening size changes or glass doors are involved. San Fernando and Burbank have their own building departments, while Los Angeles neighborhoods use LADBS. When a permit is required by your city or HOA, we coordinate the paperwork so the job is done to code.

Are new doors energy efficient and Title 24 compliant?

Yes. The glass doors we install use Low-E dual-pane insulated glass that meets California Title 24 energy standards, and new weatherstripping seals out drafts. In the hot San Fernando Valley, that means less heat coming through patio glass and a more comfortable home with lower cooling costs.

What warranty comes with a Milgard door?

Milgard doors come with the Milgard manufacturer warranty, which is among the strongest in the industry, and we add our workmanship warranty on the installation. As a Milgard Certified Dealer we install to manufacturer spec, which keeps that warranty protected. We review the coverage with you at the final walkthrough.

Do you install doors in my city?

We install doors throughout San Fernando and the San Fernando Valley, including Sylmar, Pacoima, Mission Hills, Granada Hills, Northridge, Van Nuys, North Hollywood, Sherman Oaks, and Burbank, plus Santa Clarita and Los Angeles. Our showroom is at 255 Parkside Dr. Call (818) 388-2560 if you are unsure about your address.
