How Installing Energy-Efficient Windows in Florissant Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save on electricity bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $313 annually on your energy bills in Florissant.
- Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Florissant
Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the average costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
According to our market research, the national average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the complete window, including the trim, frame and sill. Pocket installations are on the simpler end and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you're still trying to decide which kind of installation you should get, you can consult with your provider and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Florissant
EcoWatch reviews are different from most reviews because we're examining these companies through a sustainability lens. We have evaluated the top window installation companies in Florissant primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, cost, quality of installation, professionalism, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like 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
Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Florissant, MO Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of replacing a window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
There are various kinds of windows you can get for your home, such as transom windows, bay windows, picture windows, double-hung and single-hung windows, slider windows, awning windows and casement windows.
Can I replace my own windows?
If you're handy and have the time and patience to do the job right, it's possible to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.
How long does window installation generally take?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
What time of year is a good time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of 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. Most importantly, the weather should be dry.
