1970s Front Door Replacement
The door is original to the house: a dark wood slab with a small diamond or rectangular window, a skinny sidelite, a storm door that rattles, and a sill that has been wet for fifty years.

1970s front door replacement is a new prehung entry door for a split-entry, rambler or two-story from that decade: the original is usually a wood or early steel slab with a small lite, a narrow sidelite and an aluminum storm. JMB Builders supplies and installs it across the Twin Cities metro, priced per door, frame included. In stock or custom ordered, lead time on the quote.

- Door, sidelite and sill replaced as one unit
- Priced per door, prehung frame included
- In stock or custom ordered; lead time on the quote
A lot of Twin Cities houses went up in the 1970s: split-entries with the door at the landing, ramblers with the door under a low eave, and two-stories with a stoop and an aluminum awning. Their front doors were a flush or lightly paneled wood slab, sometimes an early steel door, with one small lite, a narrow sidelite in its own frame or sharing the door frame, and an aluminum combination storm. The sill under all of it was set straight on the subfloor with no pan.
Fifty winters later the slab is often fine and the frame is not: the jamb feet are soft, the threshold is loose, the weatherstrip is gone and the deadbolt barely lands in a strike that has been moved twice. The replacement is a prehung unit, frame included, so the sill and jambs are new, sized to the opening the house has. If the sidelite shares the frame, the door and sidelite are replaced together as one unit; if it is separate and sound, it can stay.
A plain steel or smooth fiberglass door in a common size is often in stock at our supplier, which suits a 1970s opening since most are standard widths. A door with a sidelite, glass, a color or a wood grain finish is custom ordered with the lead time written on the quote. The storm door comes off and is remounted on the new brickmould if it fits, or retired. New trim is primed and caulked; painting is quoted as a separate line, or paint it yourself.

How it is priced: per door
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Door only vs. door with sidelite as one unit
- In-stock steel or smooth fiberglass in white vs. custom ordered glass, color or finish
- Rot at the sill, jamb feet and subfloor after decades without a sill pan
- A split-entry landing or low rambler stoop and how the threshold meets it
- Siding, brick or stucco around the opening
- Interior casing kept, matched or replaced
- Storm door kept, remounted, replaced or retired
Include the sidelite in your photos. Whether it shares the door frame decides whether the order is a door or a door-and-sidelite unit.
How long it takes
About a day on site, more with rot repair. An in-stock door is picked up for the install soon after the measure; a door with a sidelite, glass or color is custom ordered with the lead time written on the quote.

Situations and options
Door and sidelite as one unit
The 1970s door and its skinny sidelite share a frame. Both come out and a new prehung door-with-sidelite unit goes in, with the sidelite glass clear or obscure.
Door only, sidelite kept
The sidelite has its own frame and is sound. The door and its frame are replaced between it and the wall, often with an in-stock door.
Split-entry landing door
The door opens onto the landing between the stairs. The threshold is set to the landing floor and the swing is checked so it clears the stair rail.
1970s Front Door Replacement: questions, answered
Should I replace my original 1970s front door?
If the frame is soft at the bottom, the threshold is loose or the door no longer seals and locks cleanly, yes, and the fix is a prehung unit with a new frame and sill, not a new slab in the old frame. JMB Builders supplies and installs it, priced per door with the frame included. Send photos and we reply within one business day, or book a free in-home estimate.
Can the narrow sidelite be replaced with the door?
Yes. If the sidelite shares the door frame, the two come out together and a new door-with-sidelite unit goes in as one piece. If it is in its own frame and sound, it can stay and only the door is replaced. We tell you which from your photos or at the measure.
Is a 1970s front door a standard size?
Most are, which means a plain steel or smooth fiberglass door in white is often in stock at our supplier and can go in soon after the measure. A door with a sidelite, glass, a color or wood grain is custom ordered with the lead time on the quote.
What is under a 1970s front door?
Usually a threshold set on the subfloor with no sill pan, so decades of meltwater have reached the jamb feet and the floor. The soft wood is cut out and replaced, and the new door goes in on a pan with flashing. The repair is quoted as its own line from your sill photo.
Can I keep the aluminum storm door?
If it fits the new brickmould and still closes well, it is remounted as part of the job. Many 1970s storms do not fit the new frame or are worn out, and a new storm door is a separate line, or the entry goes without one.
What style looks right on a 1970s split-entry?
A simple door: a smooth or lightly paneled slab, a half-lite or a small lite, with a sidelite in clear or obscure glass. Heavy colonial raised panels and arched decorative glass tend to look added-on. A solid paint color does more for a split-entry than a fancy door.
