Back Door Replacement — Rear, Side and Kitchen Doors to the Yard
The back door gets used more than the front, sits under a deck or at a stoop, and usually wears out first.

Back door replacement covers the rear, side or kitchen door out to the deck, stoop or yard. JMB Builders does it across the Twin Cities metro: we measure the opening, order a prehung door with the glass and swing that fit the space, pull the old door and frame, repair sill rot, set the new unit in a sill pan with flashing, and trim it. Priced per door, quoted from photos.
- Priced per door, door supplied
- Glass options that let light into the kitchen
- Sill set to the deck or stoop height
Back doors take more traffic than front doors: kids, dogs, groceries, trash. They often open to a deck or a concrete stoop with no roof over it, so the sill takes rain and snow, and the bottom of the frame rots first. Many are a builder-grade steel door with a small window, a worn weatherstrip and a lock that has to be lifted to latch.
A back door also has to work with what is around it. The sill height has to clear the deck boards or stoop outside and the flooring inside. The swing has to clear cabinets, a table or a wall in a kitchen or mudroom. Glass choices matter because this door is often the only light in a back hall: half-lite, full-lite, or glass with blinds between the panes so there is nothing to dust.
We measure, order a prehung door that fits the opening and the room, and install it with a sill pan, flashing, foam and sealant, then trim both sides. A storm door or pet door can be added as its own line. Painting is quoted as a separate line — or leave it primed and caulked and paint it yourself.

Situations and options
Kitchen door to a deck
A half- or full-lite door that brings light into the kitchen. The sill is set so the door clears the deck boards and the floor inside.
Side door off a driveway
A solid or small-lite door, often under an overhang. Common spot for a storm door and a keypad deadbolt.
Door with blinds between the glass
Blinds sealed inside the glass so there are no cords or slats to clean and nothing to snag on the way out.
Back Door Replacement — Rear, Side and Kitchen Doors to the Yard: questions, answered
Why does my back door rot at the bottom when the front door is fine?
Back doors often open to a deck or stoop with no roof over it, so the sill takes rain and melting snow. A deck set too close to the sill holds water against it too. We fix the rot and set the new door in a sill pan so water drains out.
What kind of door is best for a back door?
Most back doors are insulated steel or fiberglass prehung units. Steel costs less and holds up to traffic; fiberglass will not dent or rust. Glass depends on whether you want light into the kitchen or privacy.
Can my back door have blinds built into the glass?
Yes. Many steel and fiberglass doors come with blinds sealed between the panes, raised and tilted by a slide on the frame. There are no cords and nothing to dust.
My back door is too close to my deck. Can you fix that?
If the deck boards sit at or above the sill, water runs toward the door. Sometimes the new door sill can be set higher; sometimes the deck boards near the door need to be lowered or trimmed back. We look at it in the photos and quote the fix.
Can you add a storm door or pet door to a new back door?
Yes. A storm door is mounted on the new brickmould after the door is in, and a pet door can be cut into the door or placed in the wall next to it. Each is its own line on the quote.
How long does back door replacement take?
About a day on site for one door in a sound opening, longer if the rim or subfloor needs repair. The wait is the door order. The opening is closed up the same day.
