How Installing Energy-Efficient Windows in St Marys Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could help you:
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
- Decrease your carbon footprint: By using less energy once you switch to energy-efficient windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
Estimated Cost of Window Replacement in St Marys
Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the average costs and the primary services that you'll find from window installers.
How Much Do New Windows Cost?
Typically, St Marys homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will add extra costs to your project.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save St Marys homeowners $303+ a year when replacing single-pane windows.
Getting free quotes from multiple installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
There are generally two types of window replacement services: 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 significant deterioration. With this service, your installers will replace the entire window, including the frame, sill and trim. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window replacement company will be able to help you choose what's best for your needs. In St Marys, the decision will mostly depend on the age of your home and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in St Marys
In our search to make your home improvements easier and more eco-friendly in St Marys, the EcoWatch team examined many companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on 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 best window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have good things to say about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that offer 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 installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
St Marys, OH Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a window can range from $450 to $650. There are several factors that affect how much it costs, which include the number of windows, how energy-efficient the windows are, local labor costs, the materials used in designing the windows, your property's location and styles and sizes of windows.
Which type of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you're getting 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.
What do window installers do?
Window installation professionals visit your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
How long does it generally take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.
Should I replace my windows all at the same time?
If you're upgrading your windows because of energy-efficiency, replacing all your windows together is the only way to gain that benefit. However, if you have just a few windows that are broken or leaky, you can replace just those.
