How Installing Energy-Efficient Windows in Portland Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could help you:
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Save money on energy bills: Since energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $403 annually on your energy bills in Portland.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Better temperature control in your home: Energy-efficient windows can lower how hard your heating system needs to work to heat your home.
Estimated Cost of Window Replacement in Portland
Let's take a look at the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
Generally, homeowners in Portland can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. These figures are based on specific characteristics of your installation, like material, size, the location of your home, type, number of windows and more.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, 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, buying certified energy-efficient windows can save Portland homeowners $403+ each year after replacing single-pane windows.
We recommend requesting free quotes from several window installers to find the one that works best for you.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant damage. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves installing a new window within the existing frame. This means instead of tearing out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which kind of installation you should get, you can consult with your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Portland
In our search to find the most reliable, eco-friendly window installers in Portland, EcoWatch examined many companies before landing on these. Along with energy efficiency, we analyzed several window installers in Portland and assigned rankings using the following methodology:
Service Area
Since this is a guide for Portland, we only included companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Portland.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included in our guide to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when 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 sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Portland's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Portland window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Portland, CT Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies do?
Window installation professionals go to your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
What time of year is the best time to replace my windows?
Although you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, it shouldn't be raining, because rain can make the installation harder.
