Whole House Window Replacement in Mound, MN
Your Mound house grew one addition at a time, and so did its windows. The lake side is soft at the sills, and you want the whole house to finally look like one house.

Whole house window replacement in Mound often starts with a lake cottage that has been added onto three or four times, so the house has windows from every decade and rot on the side that faces Lake Minnetonka. JMB Builders checks every opening down to the framing, lists each on the quote, and brings the whole house to one line and color. Priced per opening. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per opening, each checked to the framing
- Additions brought to one line and color
- Lake-side rot found before the order
Mound sits at the west end of Lake Minnetonka, and much of its housing started as a cottage. Over the decades a porch was closed in, a bedroom went on the back, a second story went up, and each addition brought its own windows: wood double-hungs in the original, aluminum sliders in the 1970s wing, vinyl in the 1990s porch. The 1960s–80s ramblers and walkouts off the lake have their own version, with the original units and a few later swaps.
The lake side is where it shows. Sun and wind off the water cook the finish and drive rain under the sills, so the jambs and sills on that wall are often soft while the street side is fine. Settled floors and additions that never quite met square add to it. Before anything is ordered we open up the suspect openings, check the sill, the jamb feet and the framing under them, and write what we find on the quote, line by line.
Then the house goes on one order so every window, cottage and addition alike, is the same line, color and glass. Odd cottage sizes are ordered to size, lake-side openings get glass that handles sun and wind, and a lake-facing patio door can join the order. Mound is a full-day trip from Zimmerman, so install days are planned together. Our job records show 2 installs in Mound, Jul 2026. Painting is quoted as a separate line — or leave it primed and caulked and paint it yourself.

How it is priced: per opening
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Number of openings and how many are custom cottage sizes
- Rot in sills, jambs or framing on the lake side, found before the order
- Insert vs. full-frame on each addition
- Glass package for the lake-facing wall
- Line and frame material, including wood-interior options
- Openings that are out of square or settled and need extra shimming and trim
- A patio door on the lake side added to the order
- Exterior trim repair and interior painting, each quoted separately
Send a photo of each side of the house, with the lake side first, and close-ups of any soft or peeling sill. The free in-home estimate includes the rot check.
How long it takes
Two to four install days for most Mound houses, more where several openings need framing repair. The lake side is done first. Days and lead time are written on the quote.

Repair, then set, lake side first

Whole House Window Replacement in Mound, MN: questions, answered
Can you make the windows on my added-onto Mound cottage all match?
Yes. Each opening is measured and ordered in the same line, color and glass, so the original cottage, the 1970s wing and the closed-in porch read as one house from the lake and from the street. Odd sizes are ordered to size. The only thing an order cannot change is the shape of an opening, and resizing is quoted separately if you want it.
Why are the windows on the lake side of my house rotting while the others are fine?
The lake wall takes direct sun, wind and spray that the sheltered sides never see. Finish fails first there, then water gets behind the sill and into the jamb feet, and the framing under the window follows. We check that wall first on every Mound estimate and write the repair on the quote before anything is ordered.
Will you find more rot once the old windows are out?
Sometimes, which is why we probe and open up the suspect openings at the estimate instead of guessing. If something more shows up on install day, we photograph it, tell you what it needs, and quote it before going further. Nothing is covered over.
Can a cottage opening that is out of square take a new window?
Yes. The new unit is ordered a little smaller than the tightest dimension, set level and square inside the opening, shimmed, and the gap is foamed and covered with trim sized to the reveal. On a badly settled opening we may suggest reframing it square, and the quote says which.
Do I need a permit to replace all my windows in Mound?
The City of Mound building department sets that rule, and a lakeshore address can bring other reviews when an opening changes size. We check for your address before the order and pull the permit when one is required.
What glass should the lake-facing windows have?
A low-E package that cuts summer heat and UV without making the view gray, in a frame stiff enough for wind off the water. We lay out the options for that wall at the estimate; the rest of the house can take a standard low-E glass in the same line so the color matches.
