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.
Manufacturer + Window Design Group.
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.
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.
What each manufacturer covers.
Parts AND labor for original homeowners. Industry-leading. Covers vinyl, fiberglass (Ultra), wood, and aluminum series. Honored by Milgard directly + we manage the claim.
Covers hardwood, Woodlore composite, Smart Drape motorized, Horizons natural woven. Patented InvisibleTilt systems backed for life. Norman honors the warranty + we facilitate.
10-year coverage on materials and workmanship for folding and stacking door systems. Aluminum and clad-wood frames. Hardware separately warranted by La Cantina.
Custom mahogany, oak, fir, alder, and walnut entry doors. Hardware and finish warranted separately. Direct manufacturer coverage facilitated by our team.
American manufacturer alternative for windows and patio doors. Limited lifetime warranty on frames + glass seals. Same proactive claim management we provide for Milgard.
Our 6-Month Check-Back
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.
Something not right? Call us first.
If you are an existing WDG customer with a warranty concern, call us directly and we will dispatch a technician. No back-and-forth with the manufacturer — we handle the claim for you.
