One of the most common questions homeowners ask is, “How long will my window replacement take?” Understanding the process and timeline helps you plan with confidence, whether you’re upgrading for energy efficiency, boosting curb appeal, or improving comfort. If you’ve been searching for windows in Kirkwood, MO, this guide walks you through every stage, so you know what to expect.
Step 1: Planning and Measuring (1–2 Days)
The process starts with a consultation and precise measurement of your existing windows. This ensures that every unit we order fits your home perfectly. During this stage, we also confirm design choices and review details such as frame style, glass type, and hardware. By investing time up front, you avoid costly mistakes later.
Step 2: Ordering and Manufacturing (2–4 Weeks)
Most replacement windows are custom-built. Once measurements are finalized, the order is placed with trusted manufacturers. The turnaround time is usually two to four weeks, depending on the complexity of your design and current production schedules. While this waiting period may seem long, it ensures that your new windows are tailored to your exact specifications.
Step 3: Pre-Installation Prep (1 Day)
Before installation, we prepare your home by protecting floors and furniture, carefully removing old windows, and inspecting openings. This step also ensures the frames are free of damage and ready for new installation.
Step 4: Installation (Half-Day to Full Day per Window)
The actual installation is often faster than homeowners expect. Standard windows may be replaced in just a few hours, while larger bay or bow windows take longer. For projects involving multiple windows, crews can often complete several in a single day. A professional team ensures airtight sealing, proper insulation, and smooth operation for long-lasting performance.
Step 5: Cleanup and Inspection (Same Day)
After installation, the work area is cleaned thoroughly. Installers test each window to confirm easy operation and a perfect fit. Homeowners receive a walk-through to see the results and ask questions. This quality check ensures satisfaction before the project is considered complete.
