To replace a patio door before winter, order it early: a white six-foot vinyl slider is often in stock and can go in soon, while a color, grids or an eight-foot door is custom ordered and the lead time on the quote decides whether it lands before the freeze. JMB Builders installs it on a sill pan across the Twin Cities metro, priced per door, frame included. Photo reply within one business day, or a free in-home estimate.
- Order early; the lead time on the quote sets the date
- White six-foot slider often in stock
- Priced per door, frame and screen included
A patio door is the coldest thing in most Minnesota living rooms: a wall of glass, a sill that meltwater runs under, and weatherstrip that was done years ago. Fall is when people notice it again and the right time to replace it, because the ground is dry, sealants cure well in cool weather, and the house is not open to a January wind while the frame goes in.
The question is whether the door can be here before the freeze, and that depends on the order. A white six-foot vinyl slider is often in stock at our supplier and can be measured, picked up and installed soon after you sign. A color, grids, blinds between the glass, an eight-foot door or a French door is custom ordered, and the factory lead time is written on the quote. We do not promise a number of days; the quote tells you the wait, and you decide whether to order the custom door or take the in-stock one now.
Patio doors can also be replaced in winter, with the room sealed off and the opening closed the same day, so missing the freeze is not the end of it. But a fall install means the sill pan, the foam and the exterior sealant all go in at the temperatures they like best. New trim goes in primed and caulked; painting is quoted as a separate line, or paint it yourself before the holidays.

Situations and options
In stock now, sealed before the freeze
The white six-foot vinyl slider from our supplier's shelf, measured and installed soon after you sign. The surest way to have a new door in before winter.
Custom ordered, if the lead time fits
A color, grids, triple pane or an eight-foot door. The factory lead time is on the quote; if it lands before the freeze, order it. If not, you decide between waiting and the in-stock door.
Missed the window, winter install
The door can still go in during winter with the room sealed off and the opening closed the same day. It is a normal job for us; fall is just the easier season for it.
Replace the Patio Door Before Winter: questions, answered
When should I order a patio door to have it installed before winter?
As early in fall as you can. An in-stock white six-foot slider can go in soon after the measure. A custom ordered door depends on the factory lead time, which is written on the quote, and that number decides whether it lands before the freeze. Send photos and we reply within one business day, or book a free in-home estimate.
Is the in-stock patio door good enough, or should I wait for a custom one?
The in-stock door is a white vinyl two-panel slider with low-e double-pane glass and a screen, which is what most houses have and what most people need. Custom buys you a color, grids, blinds between the glass, triple pane or a different size. If the lead time on the quote runs past the freeze and the old door is bad, the in-stock door now is the practical choice.
What happens if the door does not arrive before the snow?
It is installed in winter. The room is closed off with plastic, the new door is on site before the old one comes out, and the opening is closed the same day with cold-rated sealants. Fall is the easier season, not the only one.
Why does my patio door frost over inside in winter?
Old glass with a failed seal or no low-e coating, worn weatherstrip letting cold air across the glass, and a frame that conducts the cold through. A new door with low-e double or triple pane glass and fresh weatherstrip stops most of it. Indoor humidity does the rest; keep it moderate.
Can one patio door be done on its own this fall?
Yes. One door is a welcome job for JMB Builders, priced per door with the frame and screen included. The windows and other doors are not part of it unless you add them.
Does the new patio door get sealed differently in fall than in winter?
Same materials, better conditions. The sill pan, flashing tape, foam and exterior sealant all go in the same way, but in fall they cure at the temperatures they are made for. In winter we use cold-rated products and keep the opening closed quickly.
