Common questions, answered.

How long does a door installation take?

Most single-door installations are completed in one day. Our crews arrive, remove the existing door, prep the frame, install the new door, and clean up before leaving. Multi-door projects or custom framing may take 1 to 2 days.

What's included in a free in-home estimate?

A Stockmohr specialist visits your home, measures the door opening, discusses the door styles that fit your home, brings samples of finishes and glass options, and provides a written quote on the spot. No obligation, no high-pressure sales.

What warranty comes with a ProVia door?

ProVia doors carry a manufacturer warranty ranging from 10 years on entry-level lines to lifetime coverage on Signet fiberglass. Stockmohr adds a lifetime workmanship warranty on top of the manufacturer coverage. [CLIENT TO CONFIRM SPECIFIC TERMS]

Do you offer financing?

Yes. We partner with home improvement lenders to offer flexible monthly payment options on any door project. Learn more about our financing options →

Fiberglass or steel: which is right for my home?

Fiberglass gives you the best energy efficiency and the most authentic wood look, but costs more up front. Steel is more affordable and offers the highest security rating. For a full comparison, read our guide: Fiberglass vs Steel Entry Doors →
