Why you can trust EcoWatch
A review of the top window installation companies in Platteville may not seem like the most interesting article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize. Traditional, outdated windows can cost you in electric bills. As a matter of fact, the Department of Energy estimates that about 30% of your house's heat or cool air could be lost through your windows.
Replacement windows improve the insulation in your home, not only making you and your family more comfortable during the summer and winter, but also saving you some money and helping the environment.
Unlike other sites, EcoWatch ranks window installation companies on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Platteville Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Better temperature control in your home: Residing in a very cold city like Platteville can often mean relying on your heater to keep your home cool. Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Save money on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $501 annually on your energy bills in Platteville.
Estimated Cost of Window Replacement in Platteville
Each window installation company provides varying services and has varying costs based on a few factors.
How Much Do New Windows Cost?
On average, Platteville homeowners can anticipate their window installations to range from $250 to $1,200. The average cost sits at approximately $600. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which have a higher price tag.
Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Requesting free quotes from multiple companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
Generally, there are two types of window installation services you can get: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the complete window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Platteville
EcoWatch reviews are different from most reviews, as we evaluate these companies through a sustainability lens. We've assessed the top window replacement companies in Platteville mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Platteville, we paid more attention to companies that cover the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Platteville.
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 on this list to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have nice things to say about their service from a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor 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 installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Platteville, WI Window Replacement FAQs
What is the average cost to install windows?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on several factors. The price is often influenced by the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
A window's energy efficiency depends on a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
