Why you can trust EcoWatch
Whether you're doing renovations or have damaged windows, windows play a key role in conserving your home's energy. Potential leaks or drafts can decrease your home's energy efficiency by up to 30%, according to the Department of Energy. In Cascades, that's around $353 per year that you could save on your electricity bills by making the switch.
That's also bad news for the environment, as the extra energy required by damaged windows increases your carbon footprint.
Unlike other sites, EcoWatch ranks window installation companies on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Cascades Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could benefit you:
- Save on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- More efficient energy usage in your home: Because the summers can get quite hot in Cascades, homeowners often depend on their air conditioner during that time. Energy-efficient windows reduce the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Cascades
Windows come in varying shapes, purposes and styles, so costs and services will vary considerably depending on your project. Below, we describe the average cost and services that you'll find from window replacement companies.
How Much Do New Windows Cost?
Even though the typical of installing a single window is around $600, it can range from $200 to $1,200. These numbers vary depending on the specifics of your installation, including size, material, type, number of windows, the location of your home and more.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Cascades homeowners $353+ each year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
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 total window. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're unsure which kind of window installation service you need, your installer can assist you. In general, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Cascades
In our search to find the most reliable, eco-friendly window installers in Cascades, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good feedback about their service from a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a spectrum 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 have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Cascades' climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Cascades window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Cascades, VA Window Replacement FAQs
How much should window installation cost?
The typical cost of replacing a single window can range from $450 to $650. There are several factors that influence the price, which include styles and sizes of windows, your property's location, local labor costs, how energy-efficient the windows are, the number of windows and the materials used in designing the windows.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
You should hire a window installation company whenever you need to replace your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.
How long does it typically take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
