Warranties & Service

If we touched it, we stand behind it.

Every window, door, shutter, and shade comes with both manufacturer warranty AND our lifetime workmanship warranty. That is the difference between a contractor and a family business in its third generation.

Two-Layer Coverage

Manufacturer + Window Design Group.

Layer 1

Manufacturer Warranty

Every product we install carries the factory warranty from the manufacturer. We only carry brands that back their products with industry-leading limited or full lifetime coverage.

Coverage details vary by product — see warranty cards below.

Layer 2

Lifetime Workmanship Warranty

From our family team to yours. Anything we installed — windows, doors, shutters, shades — anything not perfect because of how we installed it, we come fix it. For as long as you own the home.

Not transferable. Original homeowner coverage. Honored by the same family that installed it.

Our 6-Month Check-Back

No other installer in SoCal does this. Ask around.

Six months after install, we come back.

Not because something broke. Because we said we would. We check every seal, every hinge, every lock. We inspect the caulk after a rainy season. We re-lubricate hardware. We make sure everything we installed is still operating the way it did on day one.

Anything not perfect gets fixed on the spot. This is part of our lifetime workmanship promise. Not optional. Not upcharged.
