How a glass block window install usually goes
- Measure: the contractor measures each rough opening and looks at the condition of the sill, frame and surrounding masonry.
- Choose: you pick the block pattern for the privacy you want, and decide whether any panel needs a vent.
- Remove: the old sash and frame come out and the opening is cleaned up. Rotted wood or loose masonry is dealt with before the new panel goes in.
- Set the panel: blocks are mortared in place or a panel built to size is set, leveled and anchored.
- Seal and finish: the outside is caulked and sealed against water and drafts, and the inside is trimmed or patched.

Why it fits Milwaukee homes
Much of Milwaukee’s housing is older, with bungalows, duplexes and close side yards where a bathroom or stairwell window looks straight at the house next door. Glass block keeps those rooms bright without curtains, and it replaces drafty old sashes with a sealed panel. Lake Michigan winters are hard on worn wood frames and failed caulk, so a well-sealed opening matters.
Choosing a contractor
Ask for proof of insurance and any credential your municipality requires for a permit, and ask whether the work needs one at your address. Get a written estimate that lists every window, the block pattern, any vents, how old frames and damaged sills will be handled, and cleanup, so you can compare bids line for line.
