How Installing Energy-Efficient Windows in Wildwood Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could help you:
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Wildwood, that’s about 763 pounds per year on average.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save some money on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Wildwood
Windows come in various styles, purposes and shapes, so costs and services will vary greatly depending on your project. Below, we detail the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Typically, Wildwood homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost varies depending on several factors, like material, the location of your home, number of windows, type, size and more.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Wildwood homeowners $376+ each year after replacing single-pane windows.
Asking for free quotes from several providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the total window, including the sill, frame and trim. Pocket installations are simpler and won’t carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
If you’re not sure which type of window installation service you need, your installer can assist you. In general, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Wildwood
The EcoWatch Reviews team is different from most reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Wildwood and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Wildwood, we only included companies that serve the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Wildwood.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that give you 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 quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Wildwood, MO Window Replacement FAQs
How much should a window install cost?
The national average cost to replace one 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 location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window should I get?
A window’s energy efficiency is affected by a variety of factors, such as the quality of the installation and what kind of window it is. 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 you replace your own windows?
If you’re handy and know how to replace a window, it’s possible to install your own windows. However, if you don’t have the time or know-how, we recommend getting a professional to do it for you.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
How long does it take to install windows?
Since the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.
