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

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:

• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In St. Marys, that’s about 476 pounds per year on average.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
• Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save $356 a year 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 be protected from fading because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in St. Marys

When considering window installation, each company offers different services and costs. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

What Services do Window Installers Offer?

In regard to window installations, there are typically two types that your provider will have: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations are on the simpler end and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

If you’re still trying to decide which type of installation to get, you can consult with your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in St. Marys

EcoWatch reviews are different from most reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in St. Marys and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve St. Marys so you can find the best window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why 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 will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of St. Marys window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
