Better light. Better airflow. Better insulation. Custom Exteriors installs Infinity from Marvin patio doors in sliding, French, folding, and multi-slide configurations, with AAMA Certified Master Installers doing the work

‍

Most Tri-Valley homeowners don't replace a patio door because the old one looks bad. They replace it because it stopped working, drafts in winter, sticking tracks in summer, seals that failed years ago. The right door fixes all of it and holds up for decades.

‍

A door replacement that
changes how you live in your home.

‍

• Lower energy bills, year-round | A door that's lost its seal is a year-round draft. Our fiberglass patio doors hold their seal through 100°F summers and cold, wet winters in ways a warped or swollen wood door can't.
• Lower energy bills – Infinity's Title 24 compliant glass packages are engineered to reduce solar heat gain and minimize thermal transfer — measurable savings on cooling costs in Tri-Valley summers.
• Noise reduction | A tight seal doesn't just keep out heat and cold. Multi-pane glass and precision fiberglass frames reduce exterior noise, meaningful for homes near high-traffic streets.
• Less upkeep, not more | Fiberglass doesn't warp, crack, or rot the way wood does, and it won't dent like steel. No annual repainting, no re-caulking every other year.
• Resale value | Patio doors are a high-impact exterior upgrade that can make your home feel brighter, more open, and better connected to outdoor living space, details buyers notice right away.
• Zero maintenance finish | ColorPlus technology is a factory-applied finish that eliminates repainting, refinishing, and the ongoing cost and inconvenience of maintaining a painted surface over time.
