Window & door replacement FAQs
- What affects the cost of window and door replacement?
- Cost depends on how many openings you are replacing, their sizes, the window or door style, frame material, glass package, and whether it is a retrofit or full-frame installation. Wall or stucco repair can also matter. We measure in your home and give you a free written estimate before any work begins.
- How long does a window replacement project take?
- After your free in-home measurement, your windows and doors are built to the exact size of each opening, which is usually the longest step. Installation is faster: many door replacements finish in a single day, and most homes take one to a few days depending on the number of windows.
- Do I need a permit to replace windows or doors?
- Often, yes. San Fernando, Burbank, and Santa Clarita have their own building departments, while Valley neighborhoods inside the City of Los Angeles use LADBS. Replacements must also meet California Title 24 energy standards. When a permit is required by your city or HOA, we coordinate the paperwork.
- Are your windows Title 24 energy efficient?
- Yes. We install Milgard windows and doors with Low-E dual-pane insulated glass that meets California Title 24 energy standards. Low-E coatings reflect much of the sun's heat, which matters in the hot San Fernando Valley, while still letting natural light into your rooms and helping cut cooling costs.
- What warranty comes with Milgard windows?
- You receive the Milgard manufacturer warranty on the products, which is among the strongest in the industry, plus our workmanship warranty on the installation. Because we are a Milgard Certified Dealer and install to manufacturer spec, your warranty stays protected. We walk you through the details at the final walkthrough.
