Why you can trust EcoWatch
Whether you're updating for aesthetics or have damaged windows, windows play a vital role in conserving energy in your home. If your windows are made of traditional materials, or are outdated or damaged, you could be losing 25-30% of your house’s heat or cool air out of them.
That’s also bad news for the environment because the extra energy required by outdated windows increases your carbon footprint.
As windows have such a large impact on your home, selecting the best company for you is a big decision to make. That’s why the EcoWatch team has put together this list of the best window replacement companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Glendale Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to consider making the switch:
- Reduce your carbon footprint: In Glendale, you can reduce your indirect greenhouse gas emissions by about 497 pounds per year after you switch to energy-efficient windows.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Installing energy-efficient windows can help reduce that number, which helps you save $426 a year on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Glendale
Let’s go over the cost of window replacement and the kinds of services offered by installers.
How Much Do New Windows Cost?
Generally, homeowners in Glendale can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost varies based on several factors, like type, size, the location of your home, material, number of windows and more.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Glendale homeowners $426+ each year after replacing single-pane windows.
How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
If you’re still debating which type of installation you should get, you can consult with your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Glendale
EcoWatch reviews are different from other reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Glendale and ranked them using the following methodology:
Service Area
Since this is a guide for Glendale, we gave more points to companies that cover the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Glendale.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, warranty, professionalism, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Glendale, WI Window Replacement FAQs
How much does a window install cost?
The typical cost to replace a window can range from $450 to $650. There are several factors that affect how much it costs, which include local labor costs, the materials used in designing the windows, the number of windows, styles and sizes of windows, your property’s location and how energy-efficient the windows are.
What are the different kinds of windows?
There are several different kinds of windows you can get for your home, such as picture windows, transom windows, awning windows, double-hung and single-hung windows, bay windows, casement windows and slider windows.
Do you really need to use a window installation company?
Unless you’re handy and have the time needed to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
