Whole house window replacement in Crystal MN usually means a 1940s–60s rambler or story-and-a-half: original wood double-hungs with storms downstairs, small windows in the upstairs knee walls and dormers, and maybe some 1990s vinyl that is aging out. JMB Builders measures every opening, quotes each on its own line, and replaces the house as one matched set. Priced per opening.

- Priced per opening, each on its own line
- Story-and-a-half dormer and knee-wall windows included
- Double-hungs, storms and old vinyl replaced as one set
Crystal's housing is compact and consistent: 1940s–60s ramblers and story-and-a-halfs on small lots, built well and lived in hard. The downstairs still has wood double-hungs with aluminum storms, or the aluminum sliders that replaced them. Upstairs in the story-and-a-halfs are the small windows in the dormers and knee walls, often the originals, often painted shut. Some houses got a round of vinyl in the 1990s, and those seals are now going too.
A whole-house order is how the mix becomes one house again. Every opening is measured in one visit, including the awkward ones up under the roof, and the quote lists each on its own line so you can see the whole house and the worst side separately. The order goes in as one line in one frame color, and the storms come off for good.
The upstairs windows take some care. Dormer openings are small and sometimes an odd size, the knee-wall windows sit low, and the roof is right outside them, so staging and flashing against the shingles matter. We measure each one rather than ordering from a chart. Where a wood sill has rotted under sixty years of storm condensation, that opening gets full-frame work; sound frames can take an insert and keep the casing. Painting of new interior trim is quoted as a separate line, or leave it primed and caulked and paint it yourself.

Whole House Window Replacement in Crystal, MN: questions, answered
Can you replace the little upstairs windows in my story-and-a-half?
Yes. Dormer and knee-wall windows are small and sometimes an odd size, so we measure each one and order to fit rather than from a chart. The roof is right outside them, so the new unit is flashed against the shingles and staged from the roof or a ladder. They go on the same order as the downstairs windows in the same line and color.
Should I keep my storm windows?
No. The storm was adding a second layer of glass to a single-pane window. An insulated double-pane replacement does that on its own, so the storms and their frames come off and go away with the old windows. No more panels to swap in fall and spring.
My 1990s vinyl windows are fogging too. Do they go on the same order?
Yes. Originals, aluminum sliders and aging vinyl all go on one order in the same line and color so the house finally matches. Each is still priced on its own line, so you can see what each part of the house costs.
Do I need a permit to replace all my windows in Crystal?
The City of Crystal building department sets that rule. Same-size replacement and changing an opening's size are treated differently in most cities, and an egress window has its own requirements. We check for your address and pull a permit when one is required.
Can you keep the wood casing inside?
Where the wood frame is square, dry and solid, an insert goes inside it and the casing stays. Where the sill has rotted, the frame comes out and new casing goes on primed. We mark each opening on the quote so you know ahead of time which rooms get new trim.
How long does a whole-house window job take in Crystal?
A rambler is usually about two install days; a story-and-a-half with upstairs windows runs two to three. Each room is closed up before we leave for the day. The order lead time is written on the quote.
