Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house’s energy efficiency can also have a considerable impact on home energy conservation. The Department of Energy estimates that heat or cool air lost through old or damaged windows could represent nearly 30% of residential energy climate use. In Mason City, where the electricity bills are an average of $73 per month, that’s almost $$262 per year wasted.
That’s also bad news for the environment, as the additional energy used by damaged windows increases your carbon footprint.
Efficient windows are of particular importance in Mason City, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $436 a year.

How Installing Energy-Efficient Windows in Mason City Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could benefit you:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Mason City, that’s about 715 pounds per year on average.
- Save money on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $436 annually on your energy bills in Mason City.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Mason City
Each window installation company provides varying services and has different price points depending on several factors.
How Much Do New Windows Cost?
Generally, Mason City homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. This is because window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
It’s also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Mason City home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Mason City
In our search to make your home improvements easier and more eco-friendly in Mason City, the EcoWatch Reviews team assessed dozens of companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, cost, professionalism, warranty, quality of parts and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Mason City’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Mason City window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Mason City, IA Window Replacement FAQs
What is the average cost to install windows?
The national average cost to replace a window is about $600 but can range between $200 and $1,200, based on several factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
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 get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
