Reply within one business day. Or call / text 763-250-3621.
Whole house window replacement in West St. Paul is usually a 1950s–60s rambler or story-and-a-half on a small lot, with wood double-hungs, an aluminum slider and some old vinyl all in the same house, trimmed in clamshell casing. JMB Builders measures every opening, replaces the house as one set, and can swap the clamshell for new casing while the walls are open. Priced per opening. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per opening, one set across the house
- New casing in place of clamshell, if you want it
- Tight side yards planned for ladder access
West St. Paul is a postwar city of ramblers and story-and-a-half houses on small lots, close enough together that a ladder on the side yard is a conversation with the neighbor. The windows are a mix: wood double-hungs with storms from the original build, an aluminum slider in the kitchen or the back bedroom, and a few vinyl units from a 1990s fix. Inside, nearly all of it is trimmed in the thin clamshell casing of the era.
We treat the house as one job. Every opening is measured and listed on its own line, the sound frames are marked for inserts and the rotted ones for full-frame, and the whole house goes on one order so the color, glass and grilles finally agree. Because the casing comes off on full-frame openings anyway, this is the cheap moment to replace the clamshell with a taller profile on those windows, or on every window in the house, as its own line on the quote.
Small lots change how we work, not what we do. We plan the ladder and staging for the tight side, protect the neighbor's plantings, and keep the old windows on the trailer instead of in the yard. We schedule West St. Paul as a full-day trip from Zimmerman, so the install runs on back-to-back days. Our job records show 2 installs in West St. Paul, Jun–Jul 2026. Painting is quoted as a separate line — or leave it primed and caulked and paint it yourself.

Whole House Window Replacement in West St. Paul, MN: questions, answered
Can you replace the clamshell trim while you replace my windows?
Yes, and it is the cheapest time to do it. On a full-frame opening the casing comes off anyway, so new casing, stool and apron in a taller profile add little labor there. Doing every window in the house is its own line on the quote, so you can see the difference and decide.
Do my wood, aluminum and vinyl windows all come out at once?
They can, and that is what gives the house one look. Each opening is on its own line, so if a 1990s vinyl unit is still sound you can mark it can wait, and we note the line and color so a later order matches. The aluminum sliders are usually the first to go; the frame has no thermal break and frosts.
How do you work on a lot where the houses are close together?
We plan the ladder and staging for the tight side before install day, set drop cloths over plantings, and keep the old units on the trailer rather than stacked in the yard. If a ladder has to stand on the lot line, a word with the neighbor ahead of time is usually all it takes.
Can I keep the picture window in front and replace the rest?
Yes. The picture window gets its own line like every other opening, and if the glass is clear and the frame is sound we mark it can wait. Many owners replace it anyway so the front of the house matches, and a new picture unit with casement flankers is an option in the same line.
Do I need a permit to replace all my windows in West St. Paul?
The City of West St. Paul building department sets that rule, and it can differ for a same-size swap and a resized opening. We check for your address before the order and pull the permit when one is required.
How long does a whole-house window job take in West St. Paul?
Usually two install days for a rambler and three with new casing throughout, scheduled back to back since it is a full-day trip for us. Each room is sealed and trimmed before the day ends, and the lead time for the windows is written on the quote.
