About Detroit Window Pros: Licensed Window Pros in MI
Detroit Window Pros works on the housing stock this city actually has. The Census Bureau's 2019-2023 American Community Survey puts the median year built for a Detroit housing unit at 1947, with roughly 115,000 units, better than a third of the stock, built in 1939 or earlier. That is a city of well-made brick houses carrying old components, which is a very different job from a city of new ones.
What that means for windows is that the opening is fixed. A punched hole in a brick wall cannot be made bigger without shoring, a new steel lintel and rebuilt returns, so the only real variables are how much of that hole stays glass and how much light the glass passes. We compute glass area per opening and put visible transmittance on the quote beside the U-factor, because in a small opening that number decides how the room feels.
When not to hire us. If your sash are sound behind a tight storm and the draft is at the casing, we will seal the perimeter and charge you for that instead of a house of windows. We decline impact packages in a county with no debris region, we will not sell triple glazing bought for sound, and we will not replace a window whose only fault is a failed sealed unit.
If you have a window project in Detroit, the fastest way to get a real number is a free on-site estimate.

How Detroit Window Pros works
How a job with Detroit Window Pros runs, start to finish
Site visit first, always. We measure, look at the real condition of the work area, and ask what you are actually trying to solve — then you get an itemized free estimate in writing with materials, scope and a realistic date on it.
Once the work starts, the same crew stays on the job until it is done. We protect the surrounding area, clean up daily, and tell you the moment something under the surface changes the plan, because the alternative is a surprise invoice and nobody wants that conversation. Written workmanship warranty on the installation itself, held separately from the manufacturer's product warranty backs the finished work.
What we will not do
We do not quote a window job over the phone, take deposits before a written scope exists, or bid work we are not set up to do properly. If your project needs a different trade, we say so and point you at someone who does it well. Losing a job is cheaper than doing one badly in Detroit.
Where Detroit Window Pros works and who we work with
Detroit, MI first, then the surrounding communities of Detroit and the inner-ring suburbs: Dearborn, Dearborn Heights, Hamtramck, Highland Park, Grosse Pointe Park, Grosse Pointe Farms, Harper Woods, Lincoln Park and more. Each of those has its own page with local detail rather than a copy of this one.
Work splits roughly between homeowners and commercial property — offices, retail, restaurants, apartment complexes and HOA boards across Detroit and the inner-ring suburbs. Start with the Detroit services, the Detroit Window Pros homepage, or just call (844) 511-2320.
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.
- ✓We write mixed specifications. Pultruded fiberglass in the four or five openings that make the rooms you live in, welded vinyl in the basement, the bath and the back hall, and one crew setting both in the same week.
- ✓We decline work we think is wrong: impact packages in a county with no wind-borne debris region, triple glazing sold as a sound answer, and replacement windows on sound sash whose only fault is a failed sealed unit.
What Detroit Customers Say
They were the only company that told us how much glass we would lose with an insert, and they wrote the numbers on the estimate. We went full-frame on the three front windows and inserts on the other eleven. The living room is noticeably brighter than it was, which is not what I expected from replacement windows.
Two other outfits quoted a whole house. These guys measured every bedroom, told us the back one already met the escape requirement, and swapped four fogged sealed units instead of four windows. Cost about a fifth of what we had budgeted. They also fixed the storm on the stair landing while they were here.
Our front bay had been leaking for years and everyone wanted to replace the whole thing. They pulled the trim, showed us the rotten seat framing, rebuilt it and reroofed the bay before setting the new units. Three seasons on and the plaster inside is still dry. Straight explanation the whole way through.
We wanted a bow window and they talked us out of it, which cost them money. They showed us that one wide picture unit in the same wall would pass more light for less, and they were right. They also templated the arched landing window on site instead of ordering a stock size. It fits perfectly.
