How Installing Energy-Efficient Windows in Portland Saves You Money
When you switch to energy-efficient windows, you may see a few perks, such as:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 65 pounds.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Portland
Each window replacement company offers varying services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
Generally, Portland homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at about $600. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will make your project cost more.
It's important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Portland homeowners $386+ a year when replacing single-pane windows.
We recommend requesting free quotes from several window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window installation services you can get: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. Full-frame installations are more involved and will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company will be able to recommend the best type for your project. In Portland, the choice will mostly depend on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Portland
In our search to find the most reliable, eco-friendly window installers in Portland, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We've reviewed the best window replacement companies in Portland mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is 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
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured on this list to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of installation, cost, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want 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 substantial investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Portland, NY Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost to install a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
Can I replace my own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are broken or drafty, you can replace just those.
