How Installing Energy-Efficient Windows in Clear Lake Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Clear Lake
Windows come in various shapes, styles and purposes, so costs and services will differ considerably depending on your project. Below, we describe the average cost and services that you'll find from window replacement companies.
How Much Do New Windows Cost?
On average, Clear Lake homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost depends on several factors, like type, number of windows, size, material, the location of your home and more.
It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Clear Lake homeowners $436+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to recommend the best type for your project. In Clear Lake, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Clear Lake
EcoWatch is different from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer 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 Clear Lake area so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, quality of parts, professionalism, warranty, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Clear Lake's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Clear Lake window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Clear Lake, IA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost to replace one window can range from $450 to $650. There are a variety of factors that influence how much it costs, which include your property's location, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows, the number of windows and local labor costs.
What kind of window is the best for energy efficiency?
A window's energy efficiency is influenced by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installers do?
Window installation professionals visit your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.
What time of year should I replace my windows?
Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
