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

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

  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Reduce your carbon footprint: By using less energy once you switch to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Save on electricity bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.

Estimated Cost of Window Replacement in St. James

When considering window installation, each company offers different services and costs. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

Generally, St. James homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.

It’s also worth noting that energy-efficient windows will typically cost more initially, but Energy Star estimates that switching out the windows on your St. James home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable deterioration. Because these installations are more involved, they will raise the total cost. Pocket installations are simpler and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

Your window replacement company should be able to help you decide what’s best for your needs. In St. James, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in St. James

The EcoWatch Reviews team differs from most reviewers since we examine these companies through a sustainability lens. We’ve reviewed the best window installation companies in St. James mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve St. James so you can find a quality window installation company near you.

Work Quality

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

Customer Reviews

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

Cost

This one is a give-and-take: as with most services, cheap window installation companies may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Due to St. James’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of St. James 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. James, NY Window Replacement FAQs

What is the average cost to install new windows?

The national average cost to install a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window should I get?

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

What services do window installation companies offer?

Window installation companies cover the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. Additionally, a lot of companies offer window manufacturing, customization and repairs.

When is it time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.

How long does window installation generally take?

Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
