Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. If your house has traditional, outdated windows, your HVAC system could be working overtime to heat or cool your home. This means higher power bills.
Replacement windows improve the insulation in your home, not only making you more comfortable during extreme temperatures, but also saving you money and helping the environment.
So if you're constructing a new home, renovating or replacing your windows in St Peters, this is the best place to get started.

How Installing Energy-Efficient Windows in St Peters Saves You Money
Switching 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:
- Save on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 763 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
Estimated Cost of Window Replacement in St Peters
Windows come in different shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and services that you'll find from the average window installation company.
How Much Do New Windows Cost?
On average, homeowners in St Peters can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. These amounts are based on specific characteristics of your installation, including number of windows, material, the location of your home, size, type and more.
It's also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star estimates that switching out the windows on your St Peters home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise getting free quotes from several window companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first step of a replacement is to decide whether you should get a full-frame or pocket installation.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your professionals will replace the complete window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in St Peters
The EcoWatch Reviews team differs from most reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for St Peters, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in St Peters.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher 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 find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including warranty, quality of installation, cost, professionalism, quality of parts and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is well 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 will earn higher rankings by our standards. We like to see at least ten years of experience.
St Peters, MO Window Replacement FAQs
How much does a window install cost?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on several factors. The price is typically dependent on the type and material of the window, the location of your property 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?
The most common kinds of windows for homes are double-hung and single-hung windows, bay windows, casement windows, transom windows, awning windows, slider windows and picture windows.
What services do window replacement companies do?
Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How long does it generally take to install windows?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. 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 the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
