Patio door replacement in Chaska MN is often a 1970s Jonathan contemporary with a slider bigger than stock: eight feet tall, or a nine- or twelve-foot opening with fixed glass beside it, in a frame that frosts. JMB Builders measures the opening, orders a narrow-framed door built to it, repairs the sill and sets it in a sill pan. Priced per door. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per door, new door included
- Tall and wide openings ordered to size
- Narrow frames that keep a contemporary look
Chaska's 1970s Jonathan neighborhoods were designed around glass. The patio door is often a full eight feet tall, or it is a standard-height slider mulled to a wide fixed panel so the whole back wall opens to the yard or the walkout. The frames are thin aluminum with no thermal break, so they frost inside in January, and the single or early double glass has long since fogged. The rollers drag, the lock barely catches, and the sill has taken water for decades.
A door this size is not a stock item, but it is a normal custom order. Sliders come in eight-foot heights and in three- and four-panel widths, and a fixed glass panel can be ordered to mull beside the door in the same frame line so the sightlines stay thin. Fiberglass and clad-wood frames are stiff enough for a tall panel and come in the dark colors these houses often wear; vinyl works in standard heights. We measure the whole opening, not just the door, and quote the layout you want.
Setting a tall, wide door means the sill has to be dead level and supported its full length. The old door comes out, the subfloor and rim are checked and soft wood replaced, a sill pan and flashing go down, and the frame is set, shimmed at the head and jambs and anchored before foam and sealant. Chaska is a scheduled full-day trip from Zimmerman, so a patio door often goes with windows or a front door. 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:
- Eight-foot height vs. standard, and the number of panels
- Fixed glass beside the door, ordered in the same frame line
- Fiberglass or clad-wood vs. vinyl, and a dark exterior color
- Rot under the sill or at the rim once the old door is out
- Same-size replacement vs. framing the opening down to a stock size
- Exterior trim against vertical cedar or panel siding
How long it takes
One tall or wide patio door: a full day on site in a sound opening. Sill repair adds hours. A custom-size order has a longer lead time, written on the quote.

Situations and options
Eight-foot slider
A full-height two-panel slider in fiberglass or clad-wood, which stays stiff at that height. Dark exterior colors and a wood or painted interior are available.
Slider with fixed panel
A standard slider mulled to a fixed glass panel in the same frame line, so a nine- or twelve-foot opening stays mostly glass with one operating door.
Frame down to stock
If you would rather have a stock-size door, the opening is framed down, insulated and sided to match. It changes the look of the wall, so we show you both on the quote.
Patio Door Replacement in Chaska, MN: questions, answered
Can you replace an eight-foot-tall sliding door in Chaska?
Yes. Eight-foot sliders are a regular custom order in fiberglass and clad-wood lines, and some vinyl lines. We measure the full opening, order to it, and set the frame with the sill level and the head anchored so a panel that tall slides true. It is a one-day install once the door is here.
My patio door has a big fixed window next to it. Does that have to be replaced too?
Usually, because it shares a frame and sill with the door and has the same frosting frame and fogged glass. The door and the fixed panel are ordered together in one frame line so the mullion between them stays thin. If the fixed panel is its own unit and sound, it can stay, and we tell you from the photos.
Why does the metal frame on my old slider frost inside?
The 1970s aluminum frame has no thermal break, so the cold runs straight through the metal to the inside face and the moisture in the room freezes on it. New sliders have insulated frames in vinyl, fiberglass or clad-wood, so the inside surface stays above the dew point and the frost stops.
Do I need a permit to replace a patio 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 a permit when one is required.
Can a new door keep the modern look of a 1970s contemporary?
Yes. Narrow-frame sliders and fixed panels in dark colors with no grilles are stock options in fiberglass and clad-wood lines, and a square-edge casing or a drywall return inside keeps the trim minimal. We bring the frame profile to the estimate so you can see the sightline.
Can the patio door go on the same trip as my windows or front door?
Yes. Chaska is a scheduled full-day trip from Zimmerman, so the door goes on the same order as windows or a front door in a matching color and is installed during the same visit.
