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  • Protect your investment: When you have an older home, your windows could also be outdated or drafty.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.

How We Choose the Best Window Installers in St. Marys

In our hunt to make your home improvements easier and more eco-friendly in St. Marys, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We’ve reviewed the top window replacement companies in St. Marys mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

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.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included on this list to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

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.

Years of Experience

Due to St. Marys’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of St. Marys window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

St. Marys, OH Window Replacement FAQs

What is the typical cost to install new windows in a home?

The average cost of installing a single window ranges between $450 and $650. There are a variety of factors that influence how much it costs, which include local labor costs, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, your property’s location and the number of windows.

What kind of window is the best for energy efficiency?

A window’s energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Can you install your own windows?

If you’re handy and have experience with similar home improvement projects, it’s possible to install your own windows. But if you don’t have the time or skills, we recommend hiring a professional.

What time of year is a good time to replace my windows?

Though you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, the weather should be dry, as rain can make the installation harder.

Should I replace all my windows at once?

If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
