How Installing Energy-Efficient Windows in Platteville Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Platteville, that’s about 715 pounds per year on average.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Platteville
Windows come in different shapes, purposes and styles, so costs and services will differ tremendously based on several factors. Below, we go over the average cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
Though the average cost to install a single window is about $600, it can range from $200 to $1,200. How much it will cost is based on several factors, such as size, number of windows, the location of your home, type, material and more.
It’s also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Platteville home can mean 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 depends on your local climate, energy rates and other factors unique to your home.
Getting free quotes from multiple installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as 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 surrounding the window after a full-frame installation. A pocket installation entails replacing a window without removing the whole frame, which tends to be less expensive than a full-frame installation.
Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Platteville
In our search to make your home improvements easier and more eco-friendly in Platteville, the EcoWatch team evaluated dozens of companies before landing on these. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Platteville, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Platteville.
Work Quality
When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good things to say about their service from a certain installer, it won’t be featured on EcoWatch.
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 the prices of providers, 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. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Platteville’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Platteville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Platteville, WI Window Replacement FAQs
What is the average cost to install windows in a home?
The typical cost of installing a window ranges between $450 and $650. There are a variety of factors that influence the price, which include your property’s location, how energy-efficient the windows are, the number of windows, styles and sizes of windows, the materials used in designing the windows and local labor costs.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How often should you replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably 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.
