How Installing Energy-Efficient Windows in Grafton Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- Better temperature control in your home: When you reside in a place like Grafton where the summers can get pretty warm, you usually need to rely on your air conditioner to keep your home cool. Energy-efficient windows can decrease how hard your AC needs to work to cool your home.
- Save money on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- Better temperature control in your home: Living in a cold place like Grafton can often mean needing your heater to keep your house cool. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Grafton
Windows come in various shapes, styles and purposes, so costs and services will vary tremendously based on several factors. Below, we detail the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
Typically, Grafton homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. Costs will differ significantly depending on the current condition of your home, the quality of your products, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. Additional services will increase overall project costs.
It's important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Grafton homeowners $433+ a year when replacing single-pane windows.
Asking for free quotes from several providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
When considering window replacements, there are typically two types that your provider will offer: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the full window, including the trim, frame and sill. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you're still debating which kind of installation you need, you can consult with your installer and get their advice. The decision mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Grafton
In our search to make your home improvements easier and more eco-friendly in Grafton, EcoWatch landed on the above companies as the best window installation companies in the city. We have evaluated the best window replacement companies in Grafton primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Grafton, 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 Grafton.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, warranty, quality of parts, quality of installation, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer 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 that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Grafton, WI Window Replacement FAQs
How much does window installation cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the different types of windows?
The most common kinds of windows for homes include: slider windows, casement windows, bay windows, awning windows, picture windows, transom windows and double-hung and single-hung windows.
Do I really need to use a window installation company?
Unless you have home repair skills and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
How long does window installation take?
Because the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, the weather should be dry, because rain can make the installation harder.
