Premium door brands we install
La CantinaWindsorMilgardAMI
Why Window Design Group for exterior doors?
Four verified door brands
La Cantina for bifold and folding systems. Windsor for custom entries and French doors. Milgard and AMI for patio sliders. We match the right brand to the right opening — not just what we sell.
Energy-rated, Title 24 compliant
Every door we install features Low-E coated, argon-filled dual-pane glass. ENERGY STAR certified. Measurable utility bill reduction vs. original single-pane or aging aluminum doors.
Factory-trained install, never subcontracted
Every door installed by our own family team. Threshold, weatherstripping, jamb seals — done right because we own the warranty. BBB A+ Accredited, CSLB Licensed.
“Our new windows are STUNNING!! Their team was easy to work with and gave us a great price. We are glad we chose Window Design Group for our windows replacement project.”
