Window Replacement
Window replacement cost depends on the size, material, and installation complexity. If you’re interested in replacing your windows, we’ll provide you with a detailed consultation as well as a free project estimate. We offer plenty of cost-effective choices that make quality window installations stress-free. We also have helpful financing plans available. For more information on the cost of window replacements, contact us today!
The size of your window depends on its application. While each window style comes in various standard sizes, custom windows are built with your unique design in mind. Window sizing needs to take into account the height of your walls and their location in the room. Our window company will professionally measure your space for the ideal fit.
Some top window styles our window company offers include single-hung windows, slider windows, and picture windows. Single-hung windows offer beautiful scenery and plenty of ventilation, while picture windows allow for uninterrupted views in rooms that don’t need extra airflow. Slider windows are easier to open than a traditional double-hung window. We’ll help you select the perfect window style for your desired function and look!
Choosing the best material for your window depends on its application. Our window company carries vinyl and fiberglass—two popular choices. Vinyl windows are a low maintenance, high-performing, and customizable choice. Fiberglass windows are less likely to warp from contracting and expanding as the weather changes. They’re also durable and come in plenty of color options.
Window replacements come in countless styles and materials such as steel and Ultrex. Wood windows are a popular choice for adding visual interest, while aluminum and aluminum wood clad provides easy maintenance. Vinyl windows are an easy option that you never have to worry about repainting. Fiberglass is an energy-efficient choice that offers extra durability and thermal efficiency.
Two of the most popular window brands that we carry are Milgard and Simonton. As a Certified Milgard Dealer, we’re able to offer top-performing window installations with strong product warranties. Our Simonton window installations are another popular choice for their diverse style, size, and material selections available. Both options are durable, attractive, and crafted to last.
Choosing the right window color depends on your style and decor. White and black are the most popular color selections because they tend to blend into a room’s color scheme. Vinyl windows are known for the ease with which they can be customized. If you’re interested in switching to a unique color for your window replacement, we’ll find the right match. Another timeless option is wood and aluminum wood-clad windows that provide a rich, timeless design.
Although window warranty coverage depends on the manufacturer, most cover everything except for the screen. Many even include accidental glass breaks! Milgard Windows come with various forms of protection including a lifetime frame warranty, 20-year glass and hardware warranty, and 10-year labor warranty. At Design Windows and Doors, we add additional coverage to all of our window installations with a 4-year labor warranty.
There are noticeable signs that let you know when it’s time for a window replacement. If your windows won’t lock correctly, are hard to clean, or are difficult to open, they should be replaced with a functioning option. If you notice drafts, fog between panes, or issues with temperature regulation, your seal might need to be replaced. We’ll replace your window with a high-performing, energy-efficient option.
If you notice signs of damage such as drafts, warping, or fog, it’s time for a window replacement. On average, windows last for 20 years. At Design Windows, we believe that if you do it right, you only need to do it once. Our certified installations are made to be energy-efficient and durable so you never have to worry about installation errors. As a family-owned business, we want you to enjoy your windows for as long as you can!
Many DIY homeowners choose to replace their windows themselves. While this can be a smart option for some, it is a complex project for those with no experience in the industry. Many window manufacturers won’t honor their warranties if they aren’t installed properly by an authorized dealer. That’s why it’s important to hire a qualified window company. As a certified window installation contractor, we’ll always make sure your windows are installed correctly.
New windows can be installed from both the inside and the outside. Pocket windows fit inside your window frame without touching your siding or trim. This is a good option if your window frame is in good condition but you’re looking to upgrade your panes. Full-frame window replacements switch out your entire frame to an improved option.
Sometimes there are noticeable signs of window damage. However, it isn’t always easy to see. You can also call Design Windows and Doors for a thorough, professional inspection. If we find signs that it’s time for new window installation, our team will provide you with a free price quote at absolutely no cost to you.
Most new-build homes use the same standard measurement specifications in their window installations. This helps streamline the window replacement process and makes ordering quick and easy. Each type of window comes with different size standards. Our trained window installers will come out to your home and take accurate measurements to determine which set of specifications you’ll need.
Each window style comes with its own specifications for its standard size. Single- and double-hung windows are popular window choices all throughout the home. Their standard size is 24 inches wide by 28 inches long. Expansive picture windows or bay windows have some of the largest sizes and can be several feet wide.
Yes! A new window installation comes with many advantages and can even increase the value of your home. If you’re looking to increase your home value, consider hiring a certified window company for maximum warranty protection. Another way to add value is by selecting energy-efficient windows. These are a popular option because they decrease your home’s monthly energy bill.
We offer one of the widest window selections in the area, including:
• XO / OX / XOX Sliding Windows • Double Single Hung & Double Casement

A Single Hung window has a fixed top sash and a movable bottom sash. A Double Hung window allows both the top and bottom sashes to move, making it easier to clean and providing better ventilation control.
Casement windows are hinged on the side and crank outward, offering excellent ventilation and an unobstructed view. Awning windows are hinged at the top and open outward from the bottom — great for letting in air even during light rain.
Yes. We carry an extensive range of geometric and architectural shapes, including half-rounds, full circles, quarter-rounds, octagons, trapezoids, triangles, eyebrows, and circle tops — perfect for adding character and natural light to any space.
Bay windows project outward from the home and typically feature a large center picture window flanked by casement windows. Bow windows are similar but use a curved arrangement of multiple lites (panes). We offer 3-lite, 4-lite, and 5-lite Bow windows with casement flankers.
