Benefits of Replacing Your Windows

When your home needs new windows, the process can seem overwhelming. However, it’s important to focus on the long-term benefits that quality replacement windows provide. Here are four key advantages to consider beyond the price and installation offered by Mainstream Home Improvement:

Energy Efficiency

One of the most significant benefits of replacing windows in Davenport, Iowa, is improved energy efficiency. High-quality, energy-efficient windows can provide better insulation, reducing heat transfer between your home’s interior and the outdoors. This can help maintain a comfortable temperature inside your home throughout the year, resulting in lower energy consumption and reduced heating and cooling costs.

Enhanced Curb Appeal

Replacing old or damaged windows can significantly boost the aesthetic appeal of your home. With a wide range of styles, colors, and materials available, new windows can transform the look of your property, making it more attractive and modern. This can also increase the perceived value of your home, which may be beneficial if you plan to sell your property in the future.

Increased Home Value

Investing in replacement windows can add value to your home in Davenport, Iowa. Prospective buyers are often attracted to homes with energy-efficient, visually appealing windows, as they recognize the long-term savings and comfort they can provide. As a result, homes with upgraded windows may sell faster and command higher prices on the market.

Reduced Noise Pollution

High-quality replacement windows can help reduce the amount of noise that enters your home from the outside. By providing better sound insulation, these windows can create a quieter, more peaceful living environment for you and your family. This is especially important if you live near busy roads or in neighborhoods with high levels of noise pollution.

Quad Cities 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.

Why do I have condensation on my windows?

Excessive humidity levels in your home is what causes condensation, not your windows. Condensation is proof of excessive moisture in the air, which can actually be fixed with a dehumidifier or the cleaning of your HVAC units by a professional technician. For more information on condensation, please visit AAMA’s website.

How much can I save by switching out my old windows with new energy efficient windows?

This answer varies depending on several factors: the characteristics of your old and new windows, the size of your home, your property’s location, and more. ENERGY STAR® has put together calculated estimates of the energy you are bound to save when replacing a single-pane or double-pane clear glass window. Ask our team for more specifics on how much money you could be saving with our windows.

Why won’t my window sash stay up?

If your window sash won’t stay up, it may be due to the wrong size window being installed or the balance of your window is off. Unfortunately, this fix requires help form the professionals as the repair is different for every window style and manufacturer. Get in touch with our team if you’re having issues with your window sash.

What window warranties do you offer?

As a window dealer of MI Windows and Doors, our window replacement products are all covered under a Limited Lifetime Customer Assurance Warranty. This allows for homeowners to order replacement parts at no additional charge when their MI windows are broken or not operating properly. Some of our windows also come with a Glass Breakage Limited Warranty where new glass can be purchased at no additional cost if your window breaks.

How can I make the window installation process go as smoothly as possible?

To have your window installation process go as smoothly as possible, make sure the opening to your windows has been cleaned before our contractor gets there. Once your custom windows are installed, make sure there isn’t any more work to be done before using your windows. Lastly, take care of your caulk and trim to make sure your windows last as long as possible.
