How Installing Energy-Efficient Windows in La Grande Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to consider making the switch:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Save money on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In La Grande, that’s about 271 pounds per year on average.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in La Grande
When considering window installation, each company offers different services and prices. Let’s go over some average costs and services.
How Much Do New Windows Cost?
Even though the national average cost to replace a single window is about $600, it can range anywhere from $200 to $1,200. This is due to the fact that the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $485 a year on your energy bills in La Grande.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering a replacement is to clarify whether you should get a full-frame or pocket installation.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won’t carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company will be able to recommend the best type for your project. In La Grande, the decision will mostly be based on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in La Grande
The EcoWatch Reviews team is different from other reviewers since we look at these companies through a sustainability lens. We’ve evaluated the best window installers in La Grande primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for La Grande, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in La Grande.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included on this list to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, quality of parts, quality of installation, cost, professionalism and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores 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 that give you 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 earn higher rankings by our standards. We like to see at least ten years of experience.
La Grande, OR Window Replacement FAQs
What is the average cost to replace windows?
The typical cost of replacing one window ranges from $450 to $650. There are a variety of factors that affect the cost, which include the number of windows, styles and sizes of windows, the materials used in designing the windows, your property’s location, how energy-efficient the windows are and local labor costs.
What type of window is the best for energy efficiency?
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. If you want to be sure you’ll have the most energy-efficient windows, look for models that have 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?
Even though you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.
What time of year is the best time to replace my windows?
Even though you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
How do you know it’s time to replace your windows?
Windows usually have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have them looked at by an expert to determine if they need any repairs or replacements.
