Patio Door With New Interior Trim
The old slider had drywall returns that cracked, or oak casing that does not match anything else anymore.

A patio door with new interior trim is the slider or French door replaced and then cased inside: jamb extensions to bring the new frame flush with the drywall, casing to match the room or a new profile, and the floor transition at the threshold finished. JMB Builders does both in one job across the Twin Cities metro, priced per door, frame included, trim as its own line. Photo reply within one business day, or a free in-home estimate.
- Door and interior trim in one job
- Priced per door, frame included; trim its own line
- Casing matched to the room or a new profile
A new patio door frame is rarely the same depth as the old one, so the inside has to be dealt with either way. If the old trim comes off and goes back on, it often does not fit. Doing new interior trim with the door means the frame is extended to the wall with jamb extensions, the casing is cut fresh to the room's profile or a new one, and the joint to the floor is finished, all while the door is open and the wall is accessible.
You choose the look. Casing to match the windows in the room, in paint grade or stain grade; a wider flat casing for a cleaner modern look; or drywall returns with a simple stool if the room has no casing anywhere. Stain-grade oak, pine or maple is matched to the existing trim as closely as the species allows. New trim goes in primed or sanded and caulked; painting or staining is quoted as a separate line, or finish it yourself.
The floor at the threshold is the detail people forget. Hardwood, tile or carpet meets the new door at a different height than the old one, and the gap is covered with a transition that suits the floor, not a bead of caulk. The door itself is a white six-foot slider often in stock, or a color, grids or French door custom ordered with the lead time written on the quote.

Situations and options
Casing matched to the room
Jamb extensions and casing cut to the same profile and species as the windows and doors in the room, so the new patio door reads like it was always trimmed.
New flat casing
A wider flat stock casing in paint grade for a cleaner look, often used when the old oak is going away room by room anyway.
Drywall returns with a stool
No casing: the drywall wraps to the frame with a corner bead and a simple stool at the bottom. Matches a room where the windows are trimmed the same way.
Patio Door With New Interior Trim: questions, answered
Does a new patio door come with interior trim?
The door comes with its frame; the interior casing and jamb extensions are added on site, which is why trim is its own line on the quote. JMB Builders does the door and the trim in one job so the wall is opened once. Send photos and we reply within one business day, or book a free in-home estimate.
Can the old trim be reused on the new patio door?
Sometimes, if it comes off clean and the new frame depth is close to the old one. Often the new frame sits deeper or shallower in the wall, and old casing has nail holes and paint lines that show. New trim cut to the opening looks right and is usually the smaller line.
Can you match my oak trim on the new patio door?
Yes. Stain-grade oak casing is cut to the same profile as the windows in the room and stained to match as closely as the wood allows. New oak and thirty-year-old oak never match perfectly on day one; the color closes as the new wood ages. Staining is quoted as a separate line.
What happens where the new door meets my floor?
The new threshold sits at a different height than the old one, so a transition piece suited to the floor covers the joint: a hardwood reducer, a tile edge or a carpet bar. It is part of the trim line, not caulked and left.
Is the patio door in stock or custom ordered?
A white six-foot vinyl slider is often in stock at our supplier and can go in soon after the measure. A color, grids, an eight-foot door or a French door is custom ordered with the lead time written on the quote. The trim is done the same day as the door either way.
Do you paint or stain the new trim?
Painting or staining is quoted as a separate line, or leave it primed and caulked and finish it yourself. Stain-grade trim is sanded and ready for your stain, or ours.
