Introduction to Windows: Why They Matter More Than You Think
The windows of a home play several important roles within the construction of the house. For example, windows should provide crystal clear views of the outdoors, protect your home from the weather, intruders, and other outside threats, and keep out bothersome noises from the street. Your home’s windows should also enhance your property’s interior and exterior aesthetic appeal, while also improving your home’s energy efficiency.
These are just some of the ways that beautiful, high-performance window products can make an impact on the overall function, beauty, and value of your property. In fact, the benefits of brand-new windows are countless—especially if your current windows are old, foggy or water damaged, cracking, broken, or otherwise defective. If your windows aren’t flooding your home with natural light and other amazing benefits, it might be time to consider a replacement.
At Legacy Remodeling, we’re always glad to help out our customers with the information they need to complete successful home improvement projects—including window replacement, one of the most popular projects in the country for homeowners. If you’re currently considering new windows and need help or advice on how to go about replacing your old ones—take a look at this master guide to window replacement, brought to you by your friendly team of window experts at Legacy Remodeling.

How Can I Tell if My Windows Need Replacement?
Windows that are no longer serving your home’s needs—whether those needs are functional or aesthetic, can be obvious to detect—for the most part. Faulty windows can be the cause of an increase in your home’s monthly utility bills due to energy loss from damaged or inefficient frames or glass or other problems. If you’ve noticed drafts coming in through tiny gaps, this would be another sign that your windows need replacement—as your home is not as tightly sealed as it should be. The ability to safely operate your windows and the need for ongoing maintenance can also be important indicators of a need to replace your windows.
Popular Window Styles for Home Renovations
Homeowners can feel overwhelmed when considering the various options they have for window replacement. There are a great many types of windows in what might seem like an endless array of styles—including custom-made shapes and designs. Choosing the right ones will depend on your personal preferences—as well as the design of your home, the existing window, and of course, your budget.
For the best outcome, we highly recommend seeking the help of an experienced and reputable window contractors like Legacy Remodeling to help you choose the best windows for your needs. At Legacy Remodeling, our design experts work closely with our customers to help them decide on the most functional and attractive window style for their homes. We also offer in-home consultations and price estimates, to help homeowners decide on the services they need and the products that will help them to achieve their home improvement goals.
Before you make an appointment with a window company, it’s a good idea to become familiarized with the styles available—in order to know what to expect with your replacement. When it comes to window designs, most of our replacement window purchases for home remodeling will fall into one of these types of windows: double-hung, single-hung, casement windows, sliding windows, and bay/bow windows, or a custom design. Here’s a bit of information on each of these popular styles, to help you determine how each of them might fit into your plans for window replacement.

The difference between single and double hung windows is that single-hung windows can only be opened at the bottom, while double-hung windows have two sashes that open both at the bottom and the top of the window. These windows can also be equipped with an inward-tilting feature, that allows for super simple cleaning of the outside surfaces from the inside of the home.




Bay windows consist of three, side-by-side windows set at an angle—usually, a larger, fixed, picture window in the middle and flanked by two fully operational windows on either side. Bow windows, on the other hand, usually consist of four or more windows set side-by-side, of equal size and design.




Choosing the Right Frames to Use for Window Replacement
When we think of windows, we don’t usually think beyond the glass—but window frame materials are a critically important feature as well. Windows can be framed in a number of materials, which will feature different characteristics and capacities for durability, energy-efficiency, beauty, and other factors.
Some of the most commonly sold window frame materials for homes in the United States are wood, fiberglass, and vinyl. Other options include aluminum, wood/plastic composite, cellular PVC, and thermoplastic alloys. Whichever material you choose, make sure it’s from a highly rated window manufacturing company—and that the material is complementary to your home style, the climate where you live, and other important considerations. A great window company will offer you expert advice on your window products, so you don’t have to worry if you’re feeling unsure about which one to choose.
For now, here’s some information you should know about wood, fiberglass, and vinyl—the bestselling window framing materials for homes in the US. For information on other materials, ask your home improvement company for details.
For those that still pine for wood frames, the good news is they can now be found pre-primed and glazed with materials that reduce damage from water, termites, and other threats. Also, homeowners can opt for composite windows that use wood on the inside while the outside is a more durable material, allowing people to enjoy the beauty of wood without the intensive upkeep or higher cost.

Window Panes 101: Innovative Glass for Energy-Efficient Homes
You may have heard the terms “single-pane” or “double-pane” in regards to windows before, but what about triple-pane or Low E glass?
In the world of windows, the more panes a product has, the more energy-efficient that product will typically be. This means that the least energy efficient windows are old single-pane windows, which feature just one pane of glass. New windows today are at least double-pane and can feature an insulating gas such as Argon between the sheets of glass that stops energy loss in its tracks. Additionally high tech low emissivity (Low-E) glass coatings can help repel heat in the summer and hold it inside during the winter. Triple-pane windows are even higher performing than double-pane and offer additional insulation and energy-efficiency.
Beyond the features of the insulated glass unit, there are other factors that you can use to determine the efficiency of a window. The first is the window’s U-Value, which should be listed in the product information from the manufacturer. The U-Value measures the energy-efficiency of a window by evaluating the rate that heat travels through it. In essence, the higher the U-Value, the faster the energy-loss and the worse the insulation is. Homeowners instead want to look for the lowest U-Value for the best energy efficient windows.
Perhaps the most important characteristic to consider however is a windows air infiltration rating. While the U value measures how well a particular material or glass insulates, the air infiltration rating measures how much air leaks through the window. The lower this rating, the less your home leaks conditioned air, helping to reduce your energy bills.

What to Look for When Choosing a Window Installation Company
Choosing a window installation company is an important decision, as it will likely affect the quality of your installation, the cost of your window replacement project, and the quality of your materials. The goal is to get the best possible installation possible, combined with the highest value products at the lowest possible price.
Homeowners can choose one of four routes when installing new replacement windows: they can hire a department store chain like Home Depot or Sears as an all-in-one service, hire trusted local window company that specializes in replacement windows, hire an unlicensed contractor for the installation, or buy and install the windows as a DIY project.
If you’re not a window expert, DIY window installation can be difficult. In fact, DIY window installation can go very wrong when done by a non-professional—and is not recommended by window experts. Window installation is an important home improvement project and should be handled by professionals for the best outcome. Along the same lines, hiring a department store or an independent contractor to install new windows might not result in the personalized experience—nor the quality installation—that homeowners expect when making this large of an investment into their homes.
In contrast, a reliable home improvement company will offer homeowners with everything they need to experience a superior window replacement project and will likely guarantee their products and installation services for years to come. Unfortunately, finding a trusted remodeling company can be tricky—as there are plenty of unlicensed window contractors advertising low rates, and scammers seeking homeowners to swindle in contractor schemes. To find a legitimate remodeling company that specializes in windows, make sure to do an internet search for companies in your area. Check reviews, read ratings, and visit the company’s website. Check for awards from organizations like the BBB, Angie’s List, or Houzz.com, and ask friends, family, and acquaintances for recommendations.
