If you are planning a window replacement project in Ann Arbor, one of the first questions you probably have is how long the work will actually take. The honest answer depends on a few key factors, but most homeowners can expect the process to move quickly once installation day arrives. Understanding the full timeline from start to finish helps you plan around your schedule and avoid surprises.
For a standard single or double-hung window replacement in an existing frame, a professional installer can typically complete the job in about one to two hours per window. A full-frame replacement, which involves removing the entire window unit down to the rough opening, takes longer and may run two to four hours per window depending on the condition of the surrounding structure. For a typical Ann Arbor home with six to ten windows, a crew of two installers can often complete the entire project in a single day. Larger homes with more windows or specialty shapes like bay windows or picture windows may require two days on site.
Ann Arbor homes vary widely in age and construction style, from historic craftsman bungalows near Old West Side to mid-century ranch homes in Burns Park and newer construction near the University of Michigan medical campus. Older homes often have wood rot, lead paint, or out-of-square frames that need to be addressed before new windows can be set properly. Cold Michigan winters can also impact scheduling since extreme temperatures affect caulking, sealing, and overall workmanship quality. Most local installers recommend completing window projects between April and October when conditions are ideal, though winter installations are possible with the right precautions. Permit requirements in Washtenaw County are generally straightforward for replacements but can add a few days to the overall timeline if approvals are needed.
The installation day itself is only part of the equation. After you choose your windows and sign a contract, custom-ordered windows typically take four to eight weeks to arrive from the manufacturer. Standard in-stock sizes can sometimes ship faster. Once the windows arrive, scheduling the installation appointment usually adds another one to two weeks depending on the contractor's current workload. In total, most Ann Arbor homeowners should plan for a six to ten week window from first consultation to finished installation.
If you are ready to get started or want an accurate timeline based on your specific home, connecting with a trusted local window installation expert in Ann Arbor is the smartest next step. A local pro can assess your existing windows, recommend the right products for Michigan weather, and give you a realistic project schedule tailored to your home.
