How Installing Energy-Efficient Windows in Jefferson 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: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Better temperature control in your home: Energy-efficient windows can lower the amount of cool air lost through your windows when cooling your home.
- Save money on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
Estimated Cost of Window Replacement in Jefferson
When considering window installation, each company provides varying services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
Generally, Jefferson homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at around $600. But prices differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.
It's also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Jefferson home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the entire window, including the sill, trim and frame. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Jefferson
In our search to find the most reliable, eco-friendly window installers in Jefferson, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Jefferson and ranked them based on the following methodology:
Service Area
Because this is a guide for Jefferson, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Jefferson.
Work Quality
We're willing to bet that you're looking for professionals who do a great 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 received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback about their service from a certain window installation 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 would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher points 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 protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Jefferson's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Jefferson window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Jefferson, WI Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost of installing a window can range from $450 to $650. There are several factors that influence the cost, such as the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows, local labor costs, your property's location and the number of windows.
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 will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and have experience with installing a replacement window, it's possible to install your own windows. However, if you don't have the time or experience, we recommend hiring a professional.
What time of year is the best time to replace my windows?
While you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
How often do you need to replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
