How Installing Energy-Efficient Windows in Cascades Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Cascades, that’s about 376 pounds per year on average.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
Estimated Cost of Window Replacement in Cascades
Let’s take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Even though the national average cost of installing one window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, including the location of your home, type, material, number of windows, size and more.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Cascades homeowners $353+ per year after replacing single-pane windows.
We advise getting free quotes from multiple window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
The first step when planning an installation is to figure out whether you need a full-frame or pocket installation.
Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your professionals will replace the whole window, including the frame, trim and sill. A pocket installation means replacing a window without removing the entire frame, which tends to be less expensive than a full-frame installation.
If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Cascades, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Cascades
In our search to make your home improvements easier and more eco-friendly in Cascades, the EcoWatch Reviews team evaluated many companies before deciding on these. We have evaluated the top window installation companies in Cascades mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
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 a quality window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks 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 the majority of customers don’t have positive things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Cascades’s climate, homeowners will want to mitigate rot, water damage and low efficiency. 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.
