Detroit Window Pros provides professional energy-efficient window installation in Detroit, MI for residential and commercial properties across Detroit and the inner-ring suburbs. More than a third of Detroit's housing was built before 1940, and on a good share of those houses the right energy purchase is not a new window at all. Saying so out loud costs us work in this city, and we go on saying it anyway.
Take the number first, because it applies either way. Wayne County is Climate Zone 5A, and Michigan's residential energy chapter caps window U-factor for that zone with no solar heat gain requirement attached to it.
The figure the state has enforced is 0.32. A tighter edition has been through rulemaking and litigation, so ask which edition your permit is reviewed under before anything gets ordered.
What is not in doubt is that the cap reaches replacement work. The state's replacement fenestration provision says that where an existing unit is replaced with a new one, including sash and glazing, the replacement has to meet the applicable U-factor requirement. A small allowance of roughly fifteen square feet of glazed area per dwelling unit exists, and that is the extent of it.
Now the honest part. The city's own historic district guidance describes this stock accurately: wood double-hung sash with wood, or far more commonly now, aluminum storm windows hung over them. A sound original sash that has been weatherstripped, behind a tight-fitting storm, traps a layer of still air and performs well beyond what its single pane suggests.
That assembly costs a fraction of replacement and keeps sash which a century of Detroit weather has already tested. Where the stiles and rails are solid and only the putty, the sash cords and the weatherstrip have failed, repair is the better purchase and we will quote it as one. A wood sash can be reglazed and rebalanced repeatedly; a failed sealed unit in a welded frame generally cannot.
Two layers of paperwork sit on top in this city. Inside a designated historic district, the Historic District Commission reviews exterior changes before a permit issues, and its window guidance expects a replacement to conform to the original in material, configuration and color. A proposal to put vinyl into a historic opening tends to come back. Budget the review time as well as the money, because it lands before the permit rather than alongside it.
The second layer is lead. The overwhelming majority of housing here predates 1978, and the federal renovation rule names window replacement specifically: paid work disturbing paint in a pre-1978 home must be performed by a certified firm using lead-safe practices. That is not an upsell. It is the condition of doing the job lawfully, and any bidder should be able to give you a firm certification number before paint is disturbed.
So our recommendation runs on condition rather than on age. Soft sills, racked frames, sash that will not hold a position and brick openings that have shifted are replacement work, and a brick opening accepts an insert cleanly. A repairable sash behind a tight storm is not replacement work, and on a 1925 house with one cold room the cheaper fix is usually also the correct one.
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 energy-efficient window installation
The difference between energy-efficient window installation that lasts and energy-efficient window installation 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.
