How Installing Energy-Efficient Windows in St. Marys Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to think about making the switch:

• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
• Save money on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your house.
• Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
• Decrease your carbon footprint: In St. Marys, you can lower your indirect greenhouse gas emissions by about 525 pounds per year once you switch to energy-efficient windows.

Estimated Cost of Window Replacement in St. Marys

Let’s take a look at the cost of replacing your windows and the types of services you may need for your home.

How Much Do New Windows Cost?

On average, St. Marys homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at around $600. Costs will vary significantly depending on the quality of your products, the current condition of your home, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.

It’s important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save St. Marys homeowners $303+ a year when replacing single-pane windows.

Another factor that influences the total cost is the material of the frame you select. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want a new style or your window has a lot of deterioration. With this service, your professionals will replace the complete window, including the frame, sill and trim. A pocket installation entails installing a new window within the frame that’s already there. So, instead of taking out the whole unit and rebuilding 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 help you figure out what’s best for your needs. In St. Marys, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.

Service Area

Because this is a guide for St. Marys, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in St. Marys.

We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, quality of parts, professionalism, cost, quality of installation and more.

Cost

This one is a give-and-take: as with most services, cheap window installation companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
