How Installing Energy-Efficient Windows in St. John 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:
- Reduce your carbon footprint: In St. John, you can reduce your indirect greenhouse gas emissions by about 622 pounds per year once you install energy-efficient windows.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in St. John
Let’s take a look at the cost of installing new windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These numbers vary depending on the specifics of your installation, including size, material, the location of your home, type, number of windows and more.
Whether or not you want energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $391 a year on your energy bills in St. John.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as 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?
The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which increase the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
Your window installation company will be able to help you decide what’s best for your needs. In St. John, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in St. John
EcoWatch differs from most reviewers since we examine these companies through a sustainability lens. We have decided to assess the best window installation companies in St. John primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for St. John, we paid more attention to companies that provide services to the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in St. John.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty 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 installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
St. John, IN Window Replacement FAQs
How much should a window install cost?
The typical cost of replacing a window ranges from $450 to $650. There are a variety of factors that influence the cost, such as your property’s location, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows and local labor costs.
What are the kinds of windows?
There are several different types of windows you can get for your home, such as casement windows, double-hung and single-hung windows, picture windows, transom windows, bay windows, awning windows and slider windows.
Can I install my own windows?
If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or experience, we recommend getting a professional to do it for you.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it’s probably time to replace all of them. By 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 stress.
