How Installing Energy-Efficient Windows in Spencer 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 switching out your windows could help you:
- Better temperature control in your home: When you reside in a place like Spencer where the winters can be very cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can decrease how hard your heater needs to work to heat your home.
- Better temperature control in your home: Energy-efficient windows can lower how much cool air is lost through your windows when cooling your home.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Spencer, that's about 715 pounds per year on average.
Estimated Cost of Window Replacement in Spencer
Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These estimates are based on the specifics of your installation, such as type, material, size, the location of your home, number of windows and more.
It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Spencer homeowners $449+ a year when replacing single-pane windows.
Requesting free quotes from multiple companies is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first step of a replacement is to clarify whether you need a full-frame or pocket installation.
Full-frame installations are necessary when you want a new style or your window has a lot of rot or deterioration. With this service, your professionals will replace the entire window, including the sill, frame and trim. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Spencer
EcoWatch is different from other reviewers because we're examining these companies through a sustainability lens. We have assessed the best window installation companies in Spencer mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Spencer area so you can find the right window installation company near you.
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 company featured in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, quality of parts, professionalism, quality of installation, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won't always provide the most quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Spencer's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Spencer window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Spencer, IA Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a single window can range from $450 to $650. There are a variety of factors that affect how much it costs, such as the number of windows, styles and sizes of windows, local labor costs, your property's location, how energy-efficient the windows are and the materials used in designing the windows.
What are the most common kinds of replacement windows?
The most common types of windows for homes are slider windows, picture windows, double-hung and single-hung windows, casement windows, awning windows, bay windows and transom windows.
Do you really need to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring a professional. The process of installing windows is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
Should I replace all my windows at the same time?
If you're upgrading your windows to save on your energy bills, replacing all your windows at once is the only way to see a noticeable difference. However, if you have just a few windows that are broken or drafty, you can replace just those.
