In Indiana, the housing stock often features older homes with single-pane windows that lose significant heat in winter and gain heat in summer. Replacement projects aim to improve insulation and reduce drafts. The state's building codes do not have unusual permitting requirements for standard window replacements, but it is always advisable to confirm local ordinances in Indianapolis or your specific municipality. Our process begins with a detailed assessment of your current window condition and measurements. We then prepare the opening, ensuring the frame is clean and level before setting the new vinyl window. Finally, we seal and flash the exterior, and finish the interior trim for a weather-tight seal.
