Whole house window replacement in Hopkins usually means a 1920s–60s bungalow, Cape or rambler near Mainstreet with original double-hungs and storms, small odd-size openings and plaster behind the casing. JMB Builders measures every opening in person, orders each window to its own size so the plaster and casing stay put, and installs room by room. Priced per opening. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per opening, each ordered to size
- Plaster and original casing kept where sound
- Small and odd openings measured in person
Hopkins is an old city by suburban standards. The streets around Mainstreet filled with bungalows and story-and-a-half Capes from the 1920s to the 1950s, and the ramblers and splits came after. Most of them still run original wood double-hungs with aluminum storms outside, and the openings are smaller and less uniform than anything in a newer suburb: a short window over the kitchen sink, narrow pairs in the dormers, a wide picture unit added in a 1960s remodel.
That is why a whole-house job here starts with a tape, not a catalog. We measure every opening in person, width and height at three points each, and order each window to that size. Where the frame is square and dry, an insert goes inside it and the plaster, casing and stool stay untouched. Where a sill has rotted or the frame is out of square, that opening is marked full-frame on the quote, with the plaster cut back only as far as needed and patched.
Everything is written one line per opening, so you can see which rooms are inserts, which are full-frame, and what can wait. One order through ABC Supply keeps the color, glass and grille pattern the same across the house, and the storms come down for good. Our job records show 3 installs in Hopkins, Mar–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 sizes rather than stock
- Insert inside a sound frame vs. full-frame where the sill or frame has failed
- Plaster patching around full-frame openings
- Line, frame material and glass package
- Dormer and knee-wall windows upstairs and the access to them
- A kitchen picture unit or other wide opening in the mix
- Doors added to the order, each its own line
- Interior trim and painting, each quoted separately
Send one photo of each side of the house and one of a typical window from inside showing the casing. The free in-home estimate is where the measuring happens.
How long it takes
A Hopkins bungalow or rambler is usually two install days; a Cape with dormer windows, two to three. Custom sizes add lead time, and both the days and the lead time are written on the quote.

Whole House Window Replacement in Hopkins, MN: questions, answered
Can you replace windows in my Hopkins bungalow without wrecking the plaster?
Yes, in most rooms. An insert window goes inside the existing frame, so the plaster, casing, stool and apron are not touched. Only an opening marked full-frame, where the sill or frame has failed, needs the casing pulled and the plaster cut back a few inches, and we patch that before we leave.
My windows are all different sizes. Does that cost more?
Each window is ordered to its own size, which is normal for a 1920s–60s house, and most lines are made to order anyway. A size outside a maker's standard range can add lead time or cost, and the quote says so on that line. Measuring in person is what keeps a custom-size order from arriving wrong.
Do I keep the storm windows after replacement?
No. A new double-pane window does the job the storm was added to do, and the storms, their frames and the screws come off and go away with the old sash. If you want the look of a storm, say so and we will talk about it, but it is not needed for warmth.
Can the little windows in the dormers and knee walls be replaced too?
Yes. Dormer and knee-wall windows on a Cape are usually small double-hungs or awnings, and they are often the worst for frost because they sit in the coldest part of the house. They go on the same order in the same line, sized to the opening, and reach is planned from inside or a ladder on the roof side.
Do I need a permit to replace all my windows in Hopkins?
The City of Hopkins building department sets that rule, and it can differ between a same-size replacement and a changed opening. We check for your address before ordering and pull the permit when one is required.
Will the new windows look right on an older house from the street?
They can. A double-hung with a grille pattern that matches the old sash keeps the front of a bungalow looking like itself, and white or an almond exterior suits most of these houses. We can also match a stained interior with a woodgrain or wood-interior line. Bring a photo of the front and we will suggest a pattern.
