The best custom front doors pair ProVia fiberglass or steel with unlimited Sherwin-Williams color options.
ProVia offers 16 paint and 16 finish choices, all backed by 10-year manufacturer warranties. Every door is built in 1/8-inch increments, so you’re getting a precise fit — not a close-enough guess.
What Homeowners Need to Know:
- Unlimited Color Freedom: Pick any shade from the full Sherwin-Williams catalog — 3,500+ colors — with warranty coverage. Factory painting uses robotic base coat, oven curing, and electrostatic finish for a 10-year hold against flaking and peeling!
- ProVia’s Track Record Speaks: ProVia has won ENERGY STAR Partner of the Year nine times — the only manufacturer to hit that mark. Signet fiberglass doors come in Mahogany, Cherry, Fir, and Oak Series with real woodgrain texture.
- Custom Sizing Down to 1/8 Inch: Doors are crafted in every 1/8-inch increment, which means no awkward gaps or shims. Professional measurements lock in an energy-efficient fit that lasts a lifetime.
- Glass That Makes It Yours: Decorative glass, grids, and built-in blind options let you match your home’s architectural style. ProVia’s artistic patterns catch eyes from the curb while keeping security and efficiency intact.
- Hardware With Substance and Style: Antique bronze, modern finishes — the best options are all on the table. Multi-point locking systems, Impact-Shield protection, and 20-gauge kick plates keep your home safe.
- Woodgrain Without the Worry: Embossed fiberglass delivers an astonishingly accurate wood look, minus the rot and warping. Seven stain options per wood series match traditional tastes!
- A Design Process That Helps: Consultations walk you through style, color, glass, and hardware selections. Free 3D previews show your transformation before installation begins.
