Detroit Window Pros provides professional double-pane window replacement in Detroit, MI for residential and commercial properties across Detroit and the inner-ring suburbs. Most of this city is older than insulated glass. The median Detroit housing unit dates from 1947 and better than a third of the stock went up before 1940, so a double-pane window is frequently the first one a house has ever carried rather than an upgrade.
Start with what the product is. Two sheets of glass, a hollow spacer bar between them packed with desiccant, and the gap sealed at the edge with argon inside it. The seal carries everything the unit claims.
When it fails, air and water vapor get into the cavity, the desiccant saturates and the insulating value drops. The symptom is haze or a dried tide line between the panes that no amount of cleaning touches. It is a glass failure, not a window failure, and that is the useful part: the unit can often be replaced inside the existing sash and frame, which costs a fraction of a new window.
That route belongs to a particular half of Detroit. Houses built from the 1980s onward have sealed units in them already and are straightforward glass candidates. The pre-war stock is wood sash with single glazing, often true divided lites, and an insulated unit is not a drop-in there. We say which of the two your house is before anybody prices anything.
Michigan licensing is worth one careful question. The state issues a Residential Builder license for complete structures and remodeling work, and a separate Maintenance and Alteration Contractor license covering named crafts and trades, so the classification printed on the card matters as much as the card. Either one has required sixty hours of prelicensure education before the examination since 1 June 2008. Ask which classification, not whether.
Permits split the same way the work does. Like-for-like replacement in an existing opening is generally straightforward through the city's buildings and safety engineering department, while cutting brick for a wider bedroom window or a basement escape opening means a lintel, structural work, a permit and an inspection. In a designated historic district the commission reviews exterior changes before a permit issues, so budget that review time ahead of the order rather than beside it.
Michigan's energy code edition has been through rulemaking and litigation, so ask which edition your permit is reviewed under before glass is ordered, and do not accept a U-factor recited from memory. We read it off the certified label on each unit, where the spacer type and the gas fill also show up. Coatings and cold-climate payback arguments live on the Low-E and triple-pane pages.
The recommendation we give most often is a refusal. Two fogged units in otherwise sound frames is a two-unit glass job, not a whole-house order, and in a city where the money is better spent on air sealing an old shell, replacing every window because one bedroom is uncomfortable is the wrong purchase. Where every sash is rotted and painted shut, it is the right 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 double-pane window replacement
The difference between double-pane window replacement that lasts and double-pane window replacement 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.
