How Installing Energy-Efficient Windows in Cottage Grove Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to consider making the switch:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 271 pounds.
- Save money on power bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save about $428 annually on your energy bills in Cottage Grove.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Cottage Grove
Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and the primary services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
Typically, Cottage Grove homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. These estimates vary based on specific characteristics of your installation, like the location of your home, material, size, type, number of windows and more.
Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Asking for free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the total window, including the frame, trim and sill. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
If you’re not sure which type of window installation service you should get, your installer should be able to advise you. Generally, the choice depends 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 Cottage Grove
EcoWatch reviews are different from most reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Cottage Grove, we only included companies that serve 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 Cottage Grove.
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 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
We analyzed trends in recent online reviews to determine the companies with the highest rates of 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 nearly every category, including warranty, quality of parts, cost, quality of installation, professionalism and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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 experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Cottage Grove, OR Window Replacement FAQs
What is the average cost to install windows in a home?
The typical cost of replacing one window can range between $450 and $650. There are several factors that affect the price, which include local labor costs, your property’s location, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows and the number of windows.
What are the types of windows?
There are various types of windows you can get for your house, such as slider windows, bay windows, awning windows, picture windows, casement windows, double-hung and single-hung windows and transom windows.
What do window installation companies do?
Window installers travel to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.
What time of year is a good time to replace my windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.
How long does it take to install windows?
Since the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.
