Patio Door Replacement in Zimmerman, MN
The slider off your deck or walkout is twenty-some years old, it fights you every time you open it, and the floor in front of it is getting soft.

Patio door replacement in Zimmerman usually means a 1990s or 2000s builder slider that drags, fogs or leaks onto the floor, often on a walkout or a deck. JMB Builders is based in Zimmerman. We measure, order the new door, pull the old one, repair soft subfloor at the sill, set the new door in a sill pan with flashing, and trim it inside and out. Priced per door, quoted from photos.

Walkouts and back decks are everywhere in Zimmerman, and most of them got a builder-grade slider when the house went up in the 1990s or 2000s. Those doors are now at the age where the rollers have worn a groove in the track, the glass has fogged between the panes, and the lock barely catches. New rollers buy a season. They do not fix a bent track or a failed seal.
The bigger problem is usually under the door. If the original slider went in without a sill pan, water has been working into the subfloor at the corners for years. On a lot with wind coming across it, rain gets driven at that sill harder than it would in a sheltered spot. When we pull the old door we check the subfloor and rim, cut out anything soft, and replace it before the new door goes down.
Then the new door is set in a pan, flashing tape lapped at the sides and head, the frame shimmed so the panel glides and the lock meets the keeper, foamed, sealed, and trimmed. Since we are based in town, a follow-up adjustment after the first hard freeze is an easy stop.

Patio Door Replacement in Zimmerman, MN: questions, answered
Why do so many patio doors in Zimmerman fail around the same time?
A large share of Zimmerman homes were built in the 1990s and 2000s with builder-grade sliders. At twenty-plus years the rollers, tracks and glass seals on those doors wear out together. Once the glass fogs or the track is grooved, replacing the door is usually the better spend than more repairs.
Can you fix the rotted floor in front of my slider?
Yes. When the old door comes out we check the subfloor and rim at the sill, cut out the soft wood and replace it before the new door goes in. The new door is set in a sill pan with flashing so the same leak does not start again.
Do you replace walkout basement patio doors in Zimmerman?
Yes. A walkout slider sits close to grade, so we look at how water and snow sit against the sill and make sure the pan and flashing are lapped to shed it. The install is otherwise the same as an upstairs door onto a deck.
Do I need a permit to replace a patio door in Zimmerman?
Many Minnesota cities do not require a permit for a same-size door swap, but rules vary and a resized opening is different. We check with the City of Zimmerman building department for your job and pull a permit if one is needed.
Should I switch my slider to a hinged patio door?
It depends on the room. A slider does not swing into furniture or onto the deck. A hinged door seals with compression and opens the full width. We can quote both, and converting a slider opening to a hinged door is its own job we do.
Do you work outside Zimmerman?
Yes. We are based in Zimmerman and replace patio doors across the north metro, including Big Lake and Princeton, and across the Twin Cities. Send photos for a reply within one business day, or book a free in-home estimate.
