To replace one window in a brick house, JMB Builders measures the masonry opening, orders a window sized to fit behind the brick returns, removes the old unit, sets the new one level and seals the joint to the brick with backer rod and sealant. One window is a welcome job across the Twin Cities metro, priced per window, custom ordered with the lead time on the quote. Photo reply within one business day, or a free in-home estimate.
- One window in brick is a welcome job
- Measured to the masonry opening before ordering
- Priced per window, window included
A window in a brick wall sits in a masonry opening that was built around the original window. The brick returns wrap the sides, a steel angle or a brick arch carries the load above, and a sloped brick or stone sill sits below. None of that moves. The new window has to be sized to that opening, which is why a window in brick is nearly always custom ordered, and why the measure is done in person before anything is ordered.
On install day the old window comes out, the opening is cleaned to the brick, and the new window is set level and plumb behind the returns on shims. Flashing tape and low-expansion foam seal it to the rough framing behind the brick, and the outside joint between the frame and the brick is filled with backer rod and sealant, not caulk alone. A brickmould or capping covers the gap if one was there before.
Inside, the window is trimmed with stops or casing to match the rooms around it, primed and caulked. Painting is quoted as a separate line, or paint it yourself. If the window is rotted, the frame comes out to the rough opening behind the brick and the soft wood is replaced before the new window is set.

How it is priced: per window
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Size and style of the window, and how tight the fit to the masonry opening is
- Custom ordered to the opening vs. a common size that happens to fit
- Rot in the wood frame or rough opening behind the brick
- Condition of the brick sill, lintel and sealant joint around the opening
- Interior trim kept, matched or replaced
- First floor vs. second story access
Send a close-up of where the old frame meets the brick on each side. That joint tells us how the old window was set and what the new one needs.
How long it takes
Half a day to a day on site for one window in brick. The window is usually custom ordered to the masonry opening, and that lead time is written on the quote; a common size that fits can be in stock.

Situations and options
Insert behind the brick returns
The old wood frame is sound. The new window is sized to fit inside it or directly in the masonry opening, set on shims, and sealed to the brick with backer rod and sealant.
Full frame behind the brick
The old frame is rotted. It comes out to the rough framing behind the brick, the soft wood is replaced, and the new window is flashed to the framing and sealed to the brick.
Matched to the other brick-wall windows
The new window is custom ordered in the same color, glass and grille pattern as the others in the wall so the one new window reads as part of the set.
One Window in a Brick Wall: questions, answered
Can you replace one window in a brick house without removing brick?
Yes. The window is sized to the existing masonry opening and set behind the brick returns, so no brick is cut or removed. The joint between the new frame and the brick is sealed with backer rod and sealant. JMB Builders does this one window at a time across the Twin Cities metro.
Is a window in a brick wall in stock or custom ordered?
Usually custom ordered, because a masonry opening is a fixed size and the window has to fit it closely. We measure in person, order the window to the opening, and write the lead time on the quote. If a common size happens to fit, an in-stock window can go in sooner.
Why does the one window in my brick wall leak when the others do not?
Often the sealant at the brick joint has failed on that one window, or the brick sill under it has an open mortar joint that sends water behind the frame. We check both at the measure. The new window is sealed to the brick with backer rod and sealant, and an open sill joint is pointed up as part of the job.
Can one window in a brick wall be made bigger or smaller?
Smaller is straightforward: the opening is furred in behind the brick and the new window is trimmed to it. Bigger means cutting brick and resetting the lintel, which is a different job we quote separately. For one replacement window, we size it to the opening you have.
Will the new window match the other windows in the brick?
If you want it to. We compare color, frame width, glass and grilles against the windows beside it and custom order the closest match, or tell you where it will differ before you sign. Send photos and we reply within one business day, or book a free in-home estimate.
Is one window in brick too small a job?
No. One window is a welcome job for JMB Builders, brick wall or not. It gets an in-person measure, a per-window quote with the window included, and the same flashing and sealing a whole-house job gets.
