Entry door replacement in Chaska MN often means a 1970s Jonathan contemporary: a flush slab beside a full-height sidelite in a thin frame, warped and leaking at the sill. JMB Builders measures the opening, orders a clean-lined prehung unit and sidelite that keep the house's narrow sightlines, repairs the sill, sets it in a sill pan with flashing and trims it. Priced per door. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per door, prehung unit and sidelite included
- Flush and narrow-lite doors that suit a 1970s contemporary
- Sill pan and flashing on every door
Chaska's Jonathan neighborhoods were planned in the 1970s with contemporary houses: low rooflines, vertical siding, big glass and entries with a flush door beside a full-height sidelite or a tall narrow lite in the slab. The trim is minimal on purpose. Fifty years on, the original slab has warped so it misses the weatherstrip, the single-pane sidelite sweats and frosts, and the sill under both has taken water. Downtown Chaska's older houses have their own door problems, but on this page we are talking about the contemporaries.
The wrong replacement here is a six-panel colonial door with brickmould. The right one keeps the lines: a smooth flush or single-vertical-lite slab in fiberglass or steel, a matching sidelite with insulated glass, narrow frames and a simple square-edge casing or a drywall return inside. Dark exterior colors are common on these houses and hold well in fiberglass. The door and sidelite are ordered as one prehung unit sized to the opening so the sightline between them stays thin.
Underneath it is the same careful install. The old unit comes out, the subfloor and framing at the sill are checked and the soft wood replaced, a sill pan goes down with flashing tape at the sides and head, and the new unit is shimmed plumb, screwed through the hinge jamb into framing, foamed and sealed. The strike, threshold and weatherstrip are adjusted so the door seals with the deadbolt thrown. Chaska is a scheduled full-day trip from Zimmerman, so a front door often rides along with a patio door or windows. Painting is quoted as a separate line — or leave it primed and caulked and 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:
- Smooth fiberglass vs. steel, and a dark or custom exterior color
- Single door vs. door with a full-height sidelite ordered as one unit
- Sidelite glass: clear, frosted, textured or with a narrow grille
- Rot at the sill and jamb feet once the old unit is out
- Exterior trim against vertical cedar or panel siding
- Handleset, deadbolt or smart lock
- Painting, quoted as a separate line
Send a photo of the whole entry from the walk showing the siding and roofline, one from inside, and a close-up of the threshold. Tell us if the sidelite sweats in winter.
How long it takes
One door with a sidelite in a sound opening: about a day on site. Sill repair adds a few hours. Lead time on a smooth fiberglass unit in a dark color is longer and is written on the quote.

Entry Door Replacement in Chaska, MN: questions, answered
Can a new front door keep the look of my 1970s contemporary in Chaska?
Yes. Smooth flush slabs and doors with a single tall narrow lite are stock items in fiberglass and steel lines, and a matching sidelite comes in the same unit. Narrow frames, no brickmould and a square-edge casing inside keep the lines the house was designed with. We bring the option sheet to the estimate.
Why does the glass beside my front door sweat and frost?
The original sidelite is single-pane glass in a thin frame, so the inside surface drops below the dew point on a cold night and the moisture in the house condenses on it. A new sidelite has insulated glass and a thermally broken frame, and the frosting stops. The water that ran off the old glass is also why the sill under it is soft.
Can the sidelite be replaced without replacing the door?
Sometimes, if the door is sound and the sidelite is its own framed unit. On most of these entries the door and sidelite share a frame and a sill, and the sill is what has failed, so replacing both as one prehung unit is the right fix. We tell you which it is from the photos.
Is a permit needed to replace a front door in Chaska?
The City of Chaska building department sets that rule. Changing the size of the opening is the usual trigger in most cities; a same-size swap is often handled differently. We check for your address and pull the permit when one is needed.
Fiberglass or steel for a modern-looking front door?
Both come smooth and in dark colors. Fiberglass does not dent and holds a dark color better on a south or west face; steel costs less and is fine under an overhang or on a shaded entry. Both are set the same way, in a sill pan on a plumb frame, which matters more than the slab.
Can the front door go on the same trip as my windows or patio door?
Yes. Chaska is a scheduled full-day trip from Zimmerman, so the door goes on the same order as a patio door or windows in a matching color and is installed during the same visit.
