Reply within one business day. Or call / text 763-250-3621.
To replace 30 windows or more, JMB Builders runs the job as a schedule: the house measured in one visit, every opening on its own quote line, one order, and an install over one to two weeks by floor and side, each opening closed the day it is opened. The per-window price flattens at this size. Twin Cities metro. Send photos and we reply within one business day, or book a free in-home estimate.
- Thirty-plus windows installed over one to two weeks
- Scheduled by floor and side, closed up every night
- Photo reply within one business day, or free estimate
Once a house passes about thirty windows, the install stops being a visit and becomes a schedule. We walk it with you and lay out the order of work: usually the main floor first on one side, then the other, then the upstairs, with bedrooms on days that suit you. The schedule is written on the quote so you know which rooms are open on which days.
Thirty windows do not have to show up on one truck. We take delivery in the order they install, so the garage is not full of crates for two weeks and nothing sits where it can be damaged. Each day's windows are checked against the opening schedule before the old ones come out.
The pricing shape is different from a small job. The measure, the order, the permit and the daily setup are the same work whether the house has eight windows or thirty-five, so at thirty they are spread thin. What still moves the number is the mix: casements, bays, big picture units and anything upstairs that needs a lift cost more than a double-hung on the main floor.

What you supply
- A photo of each window from inside, labeled by room and floor
- Photos of all four sides of the house from the yard
- Your room order preferences: bedrooms, a home office, nursery nap times
- Space in the garage or driveway for staged deliveries
- A paint color if you want the new trim painted; painting is a separate line
What JMB supplies
- A written install schedule by floor and side, agreed with you before the order
- One in-person measure of every opening in one visit
- One order so frame color, glass and grilles match across the house
- Staged deliveries in install order, each checked against the opening schedule
- Removal, sill pans, flashing, foam, sealant and trim at every opening
- Ladders, roof brackets or a lift for second-story and gable windows
- Daily cleanup and haul-away, and photos in your job folder
How it is priced: per opening
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- The mix of styles across thirty openings: casements, bays and picture units vs. double-hungs and sliders
- How many windows are upstairs, in gables or over a roof and need a lift or brackets
- Insert in sound frames vs. full frame with new flashing and trim
- Brand, series, frame color, glass package and grilles
- Interior finish across the house: trim kept, new casing or drywall returns
- Siding, stucco or brick and how the exterior is finished at each opening
- Rot found when windows come out, priced as written on the quote
Number the photos by floor and room. The opening schedule on the quote uses the same numbers, and so does each delivery.
How long it takes
Lead time depends on the brand and is on the quote. Thirty inserts usually install in six to eight working days; full frame, a lift or new trim throughout pushes it toward two weeks.

Walkthrough and invoice
We walk the finished work with you. If anything is not right, we fix it before we call the job done. Then one invoice, paid by check or direct deposit — no card fees, no payment links.
Situations and options
One stretch, one to two weeks
The crew comes every working day until the last window is trimmed. The fewest disruptions overall, and the house is finished in one go.
Two blocks, main floor then upstairs
The main floor is done in one week and the upstairs a few weeks later, around travel or a busy stretch. Still one order, so everything matches.
Windows and exterior doors together
At thirty openings the entry and patio doors often go on the same order and schedule, so colors and hardware are picked once.
Replace 30+ Windows: Large-House Scheduling and Pricing Shape: questions, answered
How long does it take to replace 30 windows?
Thirty inserts in sound frames usually take six to eight working days with one crew. Full-frame replacement, new interior casing throughout, or a lot of second-story windows that need a lift push the job toward two weeks. The schedule is written by floor and side before the order, and every opening is closed the same day.
Is the price per window lower when you replace 30 at once?
The per-window price settles down, yes. The measure, the order, the permit and the daily setup are about the same work on any house, so across thirty windows they are a small share of each line. The windows themselves cost what they cost; a casement is still more than a double-hung.
Do all 30 windows arrive at once?
No. We stage deliveries in install order, so the first days' windows come first and the upstairs units arrive when the main floor is done. Each delivery is checked against the opening schedule. Your garage is not full of crates for two weeks.
Which rooms are open on which days?
The quote carries an install schedule by floor and side. You pick the order that suits the household, such as bedrooms on a weekday or the home office last. Only one or two openings are open at a time, and each is sealed and locked before we leave that day.
Can you quote 30 windows from photos?
For a first number, yes. Send a photo of each window labeled by floor and room and a photo of each side of the house, and we reply within one business day with a line per window. The quote is firmed when every opening is measured in person, before anything is ordered.
Should the doors go on the same order as 30 windows?
Usually. A house with thirty windows often has an entry door, a patio door and a service door that are the same age. Putting them on the same order means the exterior color, glass look and hardware are chosen once, and they fall into the same schedule.
