How messy is window replacement? Moderately, for a short time at each window: pulling the old unit and trim drops dust, old caulk, insulation and a few nails, and cutting trim makes sawdust. Floors are covered, the mess stays within a few feet of the window, and the room is vacuumed before the next one. JMB Builders installs across the Twin Cities metro.

  • Mess stays within a few feet of each window
  • Floors covered, room vacuumed before the next window
  • Plaster and stucco make the most dust

Most of a window replacement happens outside the wall or inside the frame. The mess inside comes from three things: pulling the old interior stops or casing, which drops dust, old paint chips and whatever was packed in the gap; pulling the old window, which can shed loose insulation and dirt from the sill; and cutting and nailing the new trim. On a drywall house with an insert window that is a dustpan's worth per window. On a plaster house, or a full-frame replacement in stucco, it is more.

We set up for it. The floor under each window is covered with a drop cloth out to a few feet, anything left on the wall near the window is moved or covered, and the saw stays outside or on a drop cloth. When the window is set and trimmed, the cloth is folded in on itself, the floor is vacuumed and the next room starts. Old windows, trim and debris go straight out to the trailer, not through the house more than once.

What we cannot do is make it zero. A little fine dust settles beyond the drop cloth, more in an old house. A person with dust allergies may want to be in another part of the house while a window is cut in. If a room has to stay clean, a bedroom with a baby or a home office, tell us and we do it first and close the door.

How do you want your quote?

Free, no obligation. Every quote is written and itemized, so you can compare it line by line.

What you supply

  • About three feet of clear floor at each window, and anything on the wall near it taken down
  • Blinds, curtains and rods removed, or left for us to take down
  • A note on which rooms need to stay cleanest, and where pets will be

What JMB supplies

  • Drop cloths under each window and over nearby furniture that cannot move
  • Cutting done outside or on a drop cloth; nails and debris picked up as we go
  • Each room vacuumed before the next window starts
  • Old windows, trim and debris out to the trailer the same day
  • A final vacuum and a walk through every room with you at the end
  • Photos of the finished windows in your job folder

How it is priced: per window

Quoted in writing from your photos, with a reply within one business day. What moves the number:

  • Insert replacement (less demolition inside) vs. full frame with the old jambs and casing out
  • Drywall vs. plaster-and-lath walls, which shed more dust at the trim line
  • Stucco or brick exteriors that need cutting at the opening
  • New interior trim vs. the old casing reset
  • Number of windows, which sets how many rooms are worked in a day

Tell us which rooms have to stay clean and we schedule them first, close them up and vacuum before moving on. It does not change the price.

How long it takes

Each window makes its mess for about an hour and is cleaned up before the next. The house is vacuumed at the end of every work day.

How Messy Is Window Replacement?: questions, answered

How much dust does window replacement make?

A little at each window for a short time. Pulling the old trim and window drops dust, old caulk and bits of insulation on the drop cloth; cutting new trim makes sawdust, which we do outside when we can. On a drywall house with insert windows it is a dustpan's worth per window. Plaster walls and full-frame work make more.

Do you cover the floors and furniture?

Yes. A drop cloth goes under each window a few feet out, and furniture that cannot move is covered. We ask you to clear about three feet in front of each window and take pictures off the wall nearby. Floors are vacuumed before we leave a room.

What about plaster or stucco dust?

Plaster-and-lath walls shed fine dust when the casing comes off, and stucco cut at an opening makes grit outside. Inside a plaster house we tape plastic around the opening on the room side, and we cut stucco from outside with the window opening sealed from the room. Expect more wiping afterward in a plaster house than in a drywall house.

Do you clean up each day?

Yes. Every window started is finished and its room vacuumed the same day, old windows and debris go out to the trailer, and the house is closed up. On a multi-day job you get your rooms back each night, with the next day's windows still in place.

Will there be debris in my yard?

A little during the day under each window outside: old caulk, bits of trim, screws. It is picked up as we go and the lawn is walked at the end of the day with a magnet for nails. Old windows go on the trailer, not in a pile in the yard.

Should I cover my things in the room?

Clear the window area and take down anything on the wall nearby, and we cover the rest. A bed near the window gets a sheet over it. If you have electronics or a desk right at the window, moving them to another room for the day is the surest way to keep dust off them.
