Davenport Replacement Window Company

There are numerous reasons to replace windows. In some cases, they may be the original windows in a home that is nearly a century old. Many of these windows feature wood frames, single-pane glass, and a weight system on a rope inside the frame. These windows tend to be non-functional, highly energy-inefficient, and may have rotted wood. In newer homes built within the last fifty years, contractors often used “contractor-grade” windows to save on construction costs and improve their profit margins. Unfortunately, many of these windows were subpar from the moment they were installed. Over time, some of these windows have stopped working, developed seal failures causing cloudiness, and may even leak air or become drafty due to deterioration. Let Mainstream Home Improvement make it easy, simple and stress-free to get new energy efficient replacement windows that will last a lifetime.

Stress-Free Window Replacement in Davenport Iowa

Mainstream Home Improvement makes acquiring new windows a breeze with our straightforward process. First, we guide you through the various types and styles of windows we offer, helping you choose the perfect option for your home. Next, we measure the window and provide a price based on your selections and measurements. To ensure accuracy, we send another team member to re-measure the windows before placing the order.

Depending on the manufacturing plant’s schedule, windows can take anywhere from two to eight weeks to produce. Once the windows are shipped to our office, we will contact you to schedule a convenient installation date. After installing your new windows, we conduct a “victory lap,” a customary practice at Mainstream Home Improvement, to ensure everything is to your satisfaction before collecting the final payment.

Windows in Davenport, Iowa Can Be Evaluated Based on the Following Energy Performance Characteristics


This measures the rate at which a window, door, or skylight transmits non-solar heat flow. For windows and glass doors, the U-factor may refer to the glass or glazing on the panes of glass. However, NFRC U-factor ratings represent the entire window performance, including frame and spacer material. A lower U-factor indicates greater energy efficiency.

Solar Heat Gain Coefficient (SHGC)

This is the fraction of solar radiation admitted through a window, door, or skylight, either transmitted directly and/or absorbed and subsequently released as heat inside a home. A lower SHGC means the window transmits less solar heat and has better shading ability. A high SHGC-rated product is more effective at collecting solar heat during the winter, while a low SHGC-rated product is more effective at reducing cooling loads during the summer by blocking heat gain from the sun.

Air Leakage

This measures the rate of air movement around a window or door in the presence of a specific pressure difference across it. A product with a low air leakage rating is tighter than one with a high air leakage rating. It’s important to note that air leakage also depends on the proper installation of a window, which is assumed in all ratings. Mainstream Home Improvement guarantees proper installation.
