Patio door replacement in Monticello, MN, from worn vinyl sliders in the 1990s-and-newer neighborhoods to tired wood patio doors in the older homes near downtown. JMB Builders measures, orders the door you pick, removes the old one, repairs rot at the sill and framing, sets the new door in a sill pan with flashing, and trims it to suit the house. Each door is priced on its own, from photos or an in-home visit.
- Priced per door, door supplied
- Sliders and hinged patio doors
- Trim matched to older houses
In the neighborhoods built from the 1990s on, the patio door is usually the original vinyl slider. The trouble with those is predictable at this age: rollers worn, the panel no longer locking tight, fog between the panes and air coming in at the meeting rail.
The older homes in the river-town core are different. A patio door there was often added in a remodel, sometimes a wood slider or a hinged door that has swollen, lost its paint at the bottom rail, or let water into a sill that was never panned. Those openings get a closer look: we check the header above, the framing at the sides and the floor below before the new door is ordered, and the inside casing is made to match the wider, older trim in the room.
Monticello homes facing open ground take wind on the door, and a door that was never sealed well leaks air there first. Whatever the house, the new door goes in a sill pan, is flashed into the wall, and is foamed and sealed so the opening is tight.

- Rot found at the sill, subfloor or framing

Patio Door Replacement in Monticello, MN: Sliders and Wood Doors: questions, answered
Can you replace an old wood patio door in a Monticello home?
Yes. The old door and frame come out, any rot in the sill and framing is repaired, and a new door goes in a sill pan. You can choose a clad-wood door to keep the wood look inside, or vinyl or fiberglass for less upkeep.
My older house had a patio door added years ago. Does that change the job?
It can. A door added in a remodel may have a header or framing that was not done the way we would do it today. We check the header, the side framing and the floor when we measure, and if something needs fixing, it is on the quote before the door is ordered.
Can the inside trim match the rest of my older Monticello home?
Yes. Older in-town homes often have wide casing and stained trim. We can make new casing to match the profile and finish, or install a standard casing if you are updating the room.
Why does cold air come in around my sliding door?
On an older slider, usually the weatherstrip at the meeting rail is worn, the rollers have dropped so the panel no longer seals, or the frame was never sealed well into the wall. Adjusting helps a little. A new door with fresh weatherstrip, set in a sill pan and sealed into the wall, fixes it.
Should I choose a sliding or hinged patio door?
A slider saves floor space because nothing swings into the room. A hinged door gives a wider opening when both panels open and has a solid, latching feel. In a small dining area a slider is usually the better fit.
Does a patio door replacement in Monticello need a permit?
A same-size replacement often does not, but it depends on the city and on whether the opening changes. We check with the City of Monticello building department and pull a permit when one is required.
