How Installing Energy-Efficient Windows in Lewisboro Saves You Money

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

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on electricity bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save about $331 annually on your energy bills in Lewisboro.
  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 65 pounds per year on average.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Lewisboro

Let’s take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. These estimates vary based on specific characteristics of your installation, like type, number of windows, size, material, the location of your home and more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lewisboro homeowners $331+ a year after replacing single-pane windows.

Another factor that influences the overall cost is the material of the frame you pick. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of damage. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to recommend the best type for your project. In Lewisboro, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Lewisboro

In our search to make your home improvements easier and more eco-friendly in Lewisboro, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Lewisboro area so you can find a quality window installation company near you.

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 you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want 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

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

Years of Experience

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

Lewisboro, NY Window Replacement FAQs

What is the typical cost to install windows in a home?

The average cost of replacing a window ranges from $450 to $650. There are many factors that influence the cost, including the number of windows, your property’s location, how energy-efficient the windows are, local labor costs, the materials used in designing the windows 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 usually the most energy-efficient and are certified by the U.S. Department of Energy.

Can you replace your own windows?

While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

What time of year should I replace my windows?

While you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, it shouldn’t be raining, because rain can make the installation harder.
