Custom window & door FAQs
What can actually be customized?
Nearly everything — shape (arches, triangles, hexagons, circles), size (from accent windows to monumental glass walls), material, color, glass package, grille patterns, hardware, and finish. If a stock unit doesn't fit your vision, we design one that does.
Does custom mean a much longer wait?
Custom units add manufacturing time — typically a few extra weeks depending on the maker and complexity. We confirm lead times before you order and schedule installation the moment product lands, so there are no surprises.
Can you match the style of my existing home?
Yes — matching architecture is the heart of custom work. Whether it's a historic bungalow in Austin or a modern build in the Hill Country, we design profiles, proportions, and finishes that look original to the home.
Do custom windows still qualify for energy-efficiency features?
Absolutely. Custom shapes and sizes are available with the same Low-E coatings, insulated frames, and performance glass packages as standard units — engineered for Central Texas heat.
