How Installing Energy-Efficient Windows in Monmouth Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to make the switch:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to 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 Monmouth
Let’s go over the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, such as number of windows, type, material, size, the location of your home and more.
It’s also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Monmouth home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first step when planning a window replacement is to figure out whether you need a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of damage. Full-frame installations require more time and labor and will increase overall costs. A pocket installation means replacing a window without removing the complete frame, which tends to be cheaper than a full-frame installation.
If you’re still trying to decide which kind of installation to get, you can ask your provider and get their advice. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Monmouth
In our hunt to find the most reliable, eco-friendly window installers in Monmouth, the EcoWatch team examined many companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:
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 it comes to new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have nice feedback about their experience with a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Monmouth’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Monmouth window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Monmouth, OR Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of replacing a window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically influenced by the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the different kinds of windows?
There are several different types of windows you can get for your home, such as transom windows, picture windows, awning windows, casement windows, double-hung and single-hung windows, bay windows and slider windows.
Do you really have to use a window installation company?
Unless you have home repair skills and have all the necessary tools to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.
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 should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
