How Installing Energy-Efficient Windows in Lewisboro Saves You Money

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

  • Protect your valuables from fading: When you upgrade 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.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: In Lewisboro, you can lower your indirect greenhouse gas emissions by about 65 pounds per year once you switch to energy-efficient windows.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Lewisboro

When looking into window installation, each company offers varying services and prices. Let’s look at some average costs and services.

How Much Do New Windows Cost?

Typically, Lewisboro homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. This is due to the fact that window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and light, 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.

Full-frame installations entail replacing the total window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Because these installations are more involved, they will raise the total cost. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to recommend the best type for your project. In Lewisboro, the choice will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Lewisboro

In our hunt to find the most reliable, eco-friendly window installers in Lewisboro, EcoWatch landed on the above companies as the top window installation companies in the city. We have assessed the best window installers in Lewisboro primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Lewisboro, we only included companies that serve the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Lewisboro.

Work Quality

When picking new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, cost, professionalism, warranty, quality of parts and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Lewisboro, NY Window Replacement FAQs

How much does window installation cost?

The typical cost to replace one window ranges from $450 to $650. There are several factors that affect the price, including your property’s location, how energy-efficient the windows are, the materials used in designing the windows, the number of windows, local labor costs and styles and sizes of windows.

What kind 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 what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Can you install your own windows?

If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. But if you don’t have the time or skills, we don’t recommend doing it on your own.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

How long does it typically take to install windows?

Since the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
