Patio doors in Anoka come in two kinds of houses. The postwar and 1970s–80s neighborhoods have original or first-replacement sliders that drag, fog and leak at the sill. The early-1900s houses in town did not start with patio doors; when one is there, it was added later, sometimes cut into a wall that was never framed for it. Both get the same check before we quote: is the header carrying the load, is the sill dry, and is the opening square.
On install day the old door comes out and the floor under the sill gets a hard look. Older sliders were rarely set in a pan, so water that got past the track often soaked the subfloor and rim. Soft wood is cut out and replaced, a sill pan goes down, flashing tape is lapped at the sides and head, and the new door is set level so the panel glides and the lock catches.
Trim is where an older Anoka house shows a cheap job. In a character home with stained casing, we match the profile and wood species so the new door does not read as a patch. In a newer house it is standard casing inside and brickmould or trim outside to suit the siding. Painting or staining is its own line on the quote.

Patio Door Replacement in Anoka, MN — Sliders and French Doors: questions, answered
Can you put a patio door in an older Anoka house that never had one?
Yes, but it is a bigger job than a swap. A window opening is cut down to the floor, a header for the wider span goes in, and the outside is patched around the new door. In an early-1900s house we check the framing and floor first, and a header that size is sized by an engineer when the span calls for it.
Should I pick a sliding or a French patio door?
A slider takes no swing space and suits a tight kitchen or a deck close to the house. A hinged French pair opens wider and fits the look of an older home, but needs room for the doors to swing. Both go in the same way: sill pan, flashing, set square, trimmed.
Why is the floor soft in front of my old sliding door?
Water gets past a worn track and down into the subfloor, and older sliders were seldom set in a sill pan. Over years the subfloor and rim under the door rot. We cut out the soft wood and replace it before the new door goes in.
Can you match the stained trim around my patio door?
Usually. We match the casing profile and wood species as close as we can and stain it to blend with the trim already in the room, which comes up often in Anoka's older homes. The finish work is quoted as its own line.
How long does patio door replacement take?
Most single patio doors are a day on site once the door is here. Sill repair, matched trim or a resized opening add time. The longer wait is the door order, and we give you the expected date when it is placed.
Do you replace patio doors in Coon Rapids and Ramsey too?
Yes. From our base in Zimmerman we replace patio doors across the north metro, including Coon Rapids, Ramsey and Champlin. Send photos from wherever the house is and we reply within one business day.
