How Installing Energy-Efficient Windows in Clarkstown Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, such as:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Save 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 reduce that number, therefore saving you about 12% more on your bills.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Clarkstown

Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is because of the fact that 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 keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Clarkstown 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. How much 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, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

When considering window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of damage. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won’t cost as much, as 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.

Your window installation company will be able to help you decide what’s best for your needs. In Clarkstown, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if it’s 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 Clarkstown

In our search to make your home improvements easier and more eco-friendly in Clarkstown, the EcoWatch team assessed many companies before settling on these. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

Because this is a guide for Clarkstown, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Clarkstown.

Work Quality

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

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies won’t always provide the highest quality service. Still, 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

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Clarkstown, NY Window Replacement FAQs

What is the average cost to replace windows in a home?

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

What type of window is the best for energy efficiency?

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

What do window installation companies do?

Window installation companies will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. In addition, some companies offer window manufacturing, customization and repairs.

Should I replace my windows all at the same time?

If you’re upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.

How long does it typically take to install windows?

Each window takes around 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
