Why you can trust EcoWatch
Whether you're doing home renovations or have old windows, windows play a important role in conserving your home's electricity. Traditional or damaged windows can cost you in power 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 your home's insulation, not only making you and your family more comfortable during extreme temperatures, but also saving you some money and helping the environment.
Efficient windows are particularly important in St. Francis, where winters are long and cold. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $426 per year.

How Installing Energy-Efficient Windows in St. Francis Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to think about making the switch:
- Better temperature control in your home: Residing in a cold city like St. Francis can often mean depending on your heater to keep your house cool. Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save on energy bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
- More efficient energy use in your household: Because the summers can get pretty warm in St. Francis, homeowners often depend on their air conditioner a lot. Energy-efficient windows reduce how much cool air is lost through your windows, which makes it easier to keep your home cool.
Estimated Cost of Window Replacement in St. Francis
Let's go over the cost of window installation and the types of services you may need for your home.
How Much Do New Windows Cost?
Generally, St. Francis homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost you varies based on several factors, including the location of your home, type, number of windows, size, material and more.
It's also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star predicts that switching out the windows on your St. Francis home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Getting 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?
Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
Your window replacement company will be able to help you understand what's best for your needs. In St. Francis, the decision will mostly be based on how old your home is and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in St. Francis
In our search to make your home improvements easier and more eco-friendly in St. Francis, the EcoWatch team evaluated dozens of companies before deciding on these. Along with energy efficiency, we evaluated several window installers in St. Francis and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the St. Francis area so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have positive things to say about their experience with 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 want to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a hefty 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
Because of St. Francis' climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of St. Francis window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
St. Francis, WI Window Replacement FAQs
How much does window installation cost?
The average cost to replace a single window can range between $450 and $650. There are many factors that affect the price, which include styles and sizes of windows, the materials used in designing the windows, the number of windows, how energy-efficient the windows are, local labor costs and your property's location.
What are the different kinds of windows?
The most common types of windows for homes include: picture windows, bay windows, double-hung and single-hung windows, casement windows, awning windows, transom windows and slider windows.
Do I really have to use a window installation company?
You should use a window installation company whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best handled by the professionals.
How long does it typically take to install windows?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
