Detroit Window Pros provides professional retrofit windows in Detroit, MI for residential and commercial properties across Detroit and the inner-ring suburbs. Detroit is the city where the honest answer is most often the expensive one. The median housing unit here dates from 1947, and roughly 115,000 units were built in 1939 or earlier. Most of the frames we probe are original wood that has had eighty winters working on it.
A retrofit sets a new window inside the frame already in the wall and leaves brick, siding, trim and plaster returns untouched. Full-frame replacement takes the frame out to the rough opening and rebuilds the opening itself. It is the only method that can change a size, and the only one that replaces the water detail rather than trusting it.
A retrofit into a bad frame buys a new window in a failing opening. That is the central risk in this market. Original double-hungs rot from the sill upward and from the exterior casing inward, and the damage sits under paint where a tape measure will never find it. We probe the sill, the jamb bottoms and the sub-sill before quoting either method.
Where the frame is sound, retrofit is genuinely the better job here. The window buck in a Detroit brick opening sits behind the masonry, so removing it can mean disturbing brick, resetting a lintel and rebuilding an interior plaster return. Weight pockets get insulated while the opening is open, because nobody opens one twice. Filling that cavity is worth more on a cold Detroit wall than a glass upgrade.
What keeping the frame costs you is glass. An insert nests inside the old frame and takes an inch or two of visible glass per side. On an upstairs bedroom that matters, because an escape opening is measured by clear opening rather than by the hole in the wall, so a window that only just qualified can finish under the minimum.
Two things land before the permit rather than beside it. In a designated historic district the Historic District Commission reviews exterior changes first, and its window guidance expects a replacement to follow the original in material, configuration and color. On a pre-1978 house the federal renovation rule names window replacement by name, and a full-frame teardown disturbs far more paint than an insert does.
Like-for-like replacement in an existing opening is the straightforward case. Cutting brick for a wider bedroom window, a basement escape opening or a patio door means a lintel, structural work, a permit and an inspection. Safety glazing follows location whichever way you go: doors and their arcs, tub and shower walls, stairs, and large low panes near a walking surface.
So the recommendation splits by house. On a sound post-war frame, retrofit what is failing and leave the rest. On a pre-1940 house with soft sills, do fewer openings properly in full frame rather than a houseful of inserts. In a historic district, restoring sound sash and fitting a good storm is often both what the commission will approve and what the house actually wants.
Our insured team brings the right materials and equipment to every job — glass area computed per opening and printed beside the unit price, visible transmittance read off the NFRC label alongside the U-factor, insert frames that add jamb depth inside the original wood box frame, full-frame units set back to the brick reveal, loose steel angle lintels bearing on both masonry jambs, cottage-style sash proportions that lift the check rail out of the sightline — and backs the work with a written workmanship warranty. We serve Detroit and nearby communities including Dearborn, Dearborn Heights, Hamtramck, Highland Park.

Materials, equipment and how we do retrofit windows
The difference between retrofit windows that lasts and retrofit windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with glass area computed per opening and printed beside the unit price, visible transmittance read off the NFRC label alongside the U-factor, insert frames that add jamb depth inside the original wood box frame, full-frame units set back to the brick reveal, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Detroit job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in Detroit and the inner-ring suburbs means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Detroit Chooses Detroit Window Pros
- ✓We measure the daylight opening before and after, and both numbers go on the estimate. On a thirty-inch Detroit opening an insert costs you roughly a fifth of the glass; on a wide one it costs almost nothing, and only one of those is worth full-frame money.
- ✓Visible transmittance sits on the quote next to the U-factor. The code here caps how much heat a window may lose and sets no solar heat gain ceiling at all, so glass built for a cooling climate is a poor trade in a Detroit February.
- ✓Net clear opening is measured through the sash in every sleeping room in the house, including the ones nobody asked about. If a room already meets the requirement we write the number down, say so, and leave it alone.
- ✓Glass is specified by elevation rather than by package. South and east openings get higher transmittance and higher solar gain, the few west lites get something tighter, and alley-facing openings get laminated glass for security.
