What Should You Consider When Buying New Windows?
So many factors go into window selection that it can become overwhelming quickly—even with professional help. Professional window installers will guide you through the process and ensure you receive the right windows for your home, but we’ve listed some top things to consider as you make decisions.
Types of Windows
Below are the most common window styles you’ll encounter during your search.
- Awning Windows: Awning windows swing open as if you’re pushing a latch. This design makes them easier to clean and ideal for climates with heavy rain, as they push rainwater away from your home rather than towards it.
- Bay Windows: A great option for increased curb appeal, bay windows use multiple flat windows set into an angled frame that protrudes from an exterior wall. This creates a small shelf or seating area indoors and a beautiful accent outside.
- Bow windows: Similar to bay windows, bow windows use custom curved windows to create a protruding circular design. They provide expansive views of lawns or gardens and are ideal for breakfast nooks and dining areas.
- Casement windows: Casement windows are one of the most popular window types. They swing out to the side or up to open and tend to be made from solid glass, lending a sleek, minimalist design.
- Custom windows: Most window replacement companies offer custom windows designed in any shape or size you want.
- Double-hung windows: Double-hung windows are among the most common. These windows have a lower and upper sash that each move up and down to open. They often have a tilted sash for easier cleaning.
- Garden windows: Garden windows are one of the best ways to add character and charm to your home. They’re similar to bay windows in that they protrude from the outside, but they have small shelves to grow plants and herbs.
- Hopper windows: Typically found in basements and bathrooms, hopper windows are ideal for rooms with limited wall space. They’re commonly used for ventilation and open from the top, tipping down.
- Picture windows: Picture windows don’t have panes or visible frames, offering unobstructed views of the outdoors and making your interior feel larger. These windows are fixed and can’t be opened but are often paired with other functional windows.
- Skylight windows: Skylights act like windows for your roof. They’re an excellent way to add more natural light to homes with limited wall space.
- Single-hung windows: Single-hung windows open vertically via their bottom window panel. The lower sash moves up and down, but the upper sash remains stationary.
- Sliding windows: Ideal for elongated walls, sliding windows have two sections usually made from single windows. One of the sections slides horizontally over the other to open or close.
- Transom windows: Transom windows are often used as decorative accent windows. They help break up space or add a design focal point. You often find them around doors or above other windows, and they tend to be semicircles, rectangles, or squares.
Window Warranties
Most window manufacturers offer limited lifetime warranties and labor warranties. Limited lifetime warranties cover the cost of the window parts but don’t always cover labor.
“Lifetime” often refers to the estimated time the window will maintain its manufactured quality. For example, lower-quality windows may have an estimated lifespan of fewer than five years, while higher-quality windows may last more than 15 years. The length of the warranty will match those estimations. However, some manufacturers mean the actual lifetime of the window. These warranties are usually transferable to new homeowners.
Limited lifetime warranties typically cover the following items:
- Accidental damage to the glass
- Broken or malfunctioning hardware
- Cosmetic defects
- Custom design aspects
- Energy-efficient glass
- Installation/errors performed by the installing contractor
- Obstructed vision/issues with the seal
- Window materials
A window installation company should offer a labor warranty covering installation. This warranty will cover installation errors, not manufacturing defects. Labor warranties may require you to pay a service call fee for requested service.
Window labor warranties typically cover:
- All installation and labor
- Glass systems and frames
- Pieces, parts, and materials
- Locks and hardware
We recommend selecting a window installer that the manufacturer approves. It makes it easier to receive coverage if a defect occurs, as the manufacturer won’t try to blame the installer or vice versa.
Labor Costs
The average labor cost to install windows ranges from $100 to $300 per window, depending on the difficulty of the installation. More standard windows, such as vinyl double-hung windows, cost less, while more unique windows cost more. Check out our window replacement cost guide to learn more about factors that can affect the cost of your window installation.
How to Choose the Best Window Installation Company
To find a good window installer, there are a few significant factors to consider, such as certifications, financing options, and warranties. We’ve listed all the key considerations below.
Check for Certification
Many window manufacturers recommend using a trained and certified installer. This helps you avoid bureaucratic headaches if any issues occur. In addition, the manufacturer should be willing to help resolve problems with a certified contractor. We recommend visiting a brand’s closest showroom to connect with local certified installers and double-check for American Window and Door Institute certification.
Financing
Many companies offer financing options to make your installation project more affordable. We recommend checking the available financing options’ full terms before committing to a payment plan. Although paying outright would help you avoid additional interest rates, choosing a payment plan allows you to make smaller payments over a longer period.
In-Home Estimates
Although many companies offer virtual and over-the-phone installation quotes, in-home estimates allow installers to properly view your current installation and review your windows’ condition. In-home consultations also ensure your windows are measured properly. With virtual consultations, homeowners are required to measure their windows themselves. This process could lead to inaccuracies.
Most of our recommended companies provide in-home estimates. Harvey Windows distributes its products directly to lumber and building supply stores, and your local installer will conduct the in-home estimate.
Installation and Material Warranties
Check the full terms and conditions of any window installation or material warranties. Window materials’ warranty coverage may vary, so review the details for your glass, frame, and component protection. High-end window warranties may last 15 to 20 years, while low-cost alternatives may only last three to five years. Installation warranties are typically shorter than material warranties, with an average length of two years.
Pay Attention to the Quote Process
There are red flags to look out for during the quote process. A reputable installer will measure each replacement window, explain their installation process, and estimate the job’s timeline. Your installer should also replace each window one by one rather than removing all the old ones and installing all the new windows at once. If an installer seems too eager to get started or tries to avoid your questions and concerns, you should consider another option.
Read Customer Reviews
We recommend checking potential companies’ customer reviews to gain insight into their installation and customer support experience. Google Reviews and the Better Business Bureau (BBB) are two reliable review sites. Search for reviews that mention any similar products or projects you’re considering for your home. Compare good and bad experiences to get a well-rounded perspective on the company. Pay attention to the criteria listed above when reading homeowner reviews, such as scheduling, warranty options, and workmanship.
In addition, review each website to see if the company is certified by the American Architectural Manufacturers Association (AAMA). AAMA installation certification, conducted by the Fenestration and Glazing Industry Alliance, is a nationally recognized program that teaches proper installation techniques and best practices.
Our Recommendation
Windows are essential to your home’s style, performance, and value, so finding the right window installation company is crucial.
Champion Windows is our top-recommended window installer because it’s well-rounded. The company manufactures completely customized replacement windows and can put its energy-efficient Comfort 365 Window Glass in practically any window you want. It’s also one of the few providers that offers comprehensive sunroom services.
Power Home Remodeling is another excellent option for a window installer. The company partners with Pella for reputable, high-quality windows and offers siding and roofing services for those looking for a comprehensive remodel. Renewal by Andersen is an excellent choice if you want a hands-free installation and unique accent windows.
Use our tool below to match with reliable window installers near you quickly. We recommend requesting at least three free quotes before making a decision.
Window Installation FAQ
Is Renewal by Andersen the same as Andersen?
Renewal by Andersen is the full-service window replacement division of Andersen. This service offers white-glove window installation from start to finish. Andersen is the parent company.
Which windows are the most energy efficient?
Energy-efficient window options vary by brand and installer, but any Energy Star-certified replacement windows are the most energy-efficient. An Energy Star-certified window is nearly twice as energy-efficient as an average replacement window.
How long does it take to replace a window?
Replacing one window takes around 40 to 60 minutes. However, it may take a company several weeks to manufacture an ordered window and establish an installation date with you.
