How Installing Energy-Efficient Windows in Sylvania Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:

  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Sylvania, that's about 525 pounds per year on average.
  • 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 harmful UV rays.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Save money on electricity bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save around $308 annually on your energy bills in Sylvania.

Estimated Cost of Window Replacement in Sylvania

Windows come in varying purposes, shapes and styles, so costs and services will vary tremendously based on several factors. Below, we go over the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

Typically, homeowners in Sylvania can anticipate that most window installations will cost between $250 and $1,200, with the average cost at around $600. This is due to the fact that the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

It's also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your Sylvania home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Another factor that influences the total cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because 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?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Sylvania, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Sylvania

In our search to find the most reliable, eco-friendly window installers in Sylvania, the EcoWatch Reviews team evaluated dozens of companies before deciding on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:

Service Area

Because this is a guide for Sylvania, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Sylvania.

Work Quality

When installing new windows, the quality and breadth of services often plays 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

Customer feedback is another super important review factor. If most customers don't have nice things to say about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

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

Warranty

As discussed, 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 labor rank higher with EcoWatch.

Years of Experience

Due to Sylvania's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Sylvania window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Sylvania, OH Window Replacement FAQs

How much should a window install cost?

The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is often influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What type of window is the best for energy efficiency?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installers cover the entire process — from replacing old windows with new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, the weather should be dry, as rain can make the installation harder.

Should I replace all my windows at the same time?

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 once will involve less paperwork and less time.
