What About Installation?
When done with 2–3 or more windows, expect door installation labor to be around $1,250-1,500.00.
This includes removal of the existing door, prepping the opening, full waterproofing, applying high-quality silicone, trimming out the interior with decorative casing, and hauling away all debris related to the installation.
Standalone door installations may be higher due to setup and crew time.
Beware of Gimmicks
“Free installation” or “40% off your second door” often just means the cost is baked into the product price. These are real, transparent prices with no games.

Milgard Sliding Door FAQ
Q: Why do Milgard sliding patio doors have such different prices between series?
A: The difference really comes down to what each series is designed for. Tuscany is the classic choice — it’s packed with features and great energy efficiency. Trinsic is all about the modern, narrow-frame look that homeowners like in newer builds. Ultra uses fiberglass, which costs more but holds up in tough climates and coastal areas where vinyl can struggle. So, the price isn’t just a markup — it’s tied to the frame material, energy ratings, and the style you want for your home.
