Whole house window replacement in Stillwater often means an 1850s–1910s house with tall wood double-hungs, some worth restoring and many past saving. JMB Builders checks every window and marks it restore, insert or full-frame on the quote, orders the replacements in custom tall sizes with grilles that match the old lites, and matches the stained casing where it has to come off. Priced per opening. Send photos and we reply within one business day, or book a free in-home estimate.
- Each window marked restore, insert or full-frame
- Custom tall sizes and matched grille patterns
- Stained casing matched where it must come off
Historic Stillwater houses carry wood double-hungs that are taller and narrower than anything built since, with weight pockets in the jambs, stained casing and sills that have taken a century of river-valley weather. Some are sound and worth keeping; many have rotted meeting rails, split sills and glass held in by paint. On the bluff lots the wind off the St. Croix tests every one of them.
A whole-house job here starts with sorting, not selling. Each window is checked for frame, sill, sash and glass and marked one of three ways on the quote: restore, where the sash and frame are sound and new weatherstrip and glazing will do; insert, where the frame is sound but the sash is gone, so a new unit goes inside the old jamb and the casing stays; or full-frame, where the sill or jamb has rotted and the whole opening is rebuilt with new casing milled to match the old profile. Mixing all three in one house is normal.
Replacements are custom-ordered in the tall sizes these houses need, with grille patterns that follow the original lites and a wood or wood-tone interior where the trim is stained. The west-side 1990s–2000s neighborhoods are a simpler job, a straight package swap with the same opening-by-opening quote. Stillwater is a scheduled full-day trip from Zimmerman, so install days are planned in advance. Painting is quoted as a separate line — or leave it primed and caulked and paint it yourself.

Whole House Window Replacement in Stillwater, MN: questions, answered
Do all the old windows in a Stillwater house have to be replaced?
No. Each one is checked and marked restore, insert or full-frame. A window with a sound frame and sash can be weatherstripped and reglazed and kept; a window with a sound frame and a shot sash gets an insert inside the old jamb; a window with a rotted sill gets rebuilt. The quote shows which and why, so you decide window by window.
Can new windows be made in the tall sizes my 1880s house has?
Yes. Replacement windows are built to the measured opening, and tall, narrow double-hungs are a normal custom order. Grille patterns can follow the original two-over-two or six-over-six lites, and arched or cottage-style sash with a taller lower pane are available in most lines.
What happens to the weight pockets and pulleys?
When an insert goes in, the weights and cords come out, the pockets are filled with insulation and sealed, and the pulley holes are covered by the new frame. That cavity was a major air leak, so this is one of the bigger comfort gains. On a full-frame opening the whole pocket is removed with the old jamb.
Do I need a permit or historic review to replace windows in Stillwater?
The City of Stillwater building department sets the permit rule, and same-size replacement and resizing an opening are usually treated differently. If your house is in a designated historic district the city may also review exterior changes. We check for your address before anything is ordered and pull a permit when one is required.
Will the new casing match my original stained trim?
Where an insert goes in, the original casing never moves. Where an opening is rebuilt, we mill new casing to the old profile, including back band where the house has it, and stain to match. The joint between old and new is planned at the measure so it lands where it will not show.
Does wind off the river change anything about the windows?
On bluff lots the river side takes the weather. We flash those openings with extra care, recommend a stiffer frame and a good glass package on that elevation, and check that old storm-window screw holes in the exterior casing are sealed. The sheltered sides of the house can be the same line without the upgrades.
