How Installing Energy-Efficient Windows in Valley Stream Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could help you:
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Valley Stream, that’s about 154 pounds per year on average.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Save money on power bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
Estimated Cost of Window Replacement in Valley Stream
Each window replacement company provides varying services and has varying price points depending on a few factors.
How Much Do New Windows Cost?
On average, homeowners in Valley Stream can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $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 companies also offer door installations and replacements, which carry a higher price tag.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, 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, purchasing certified energy-efficient windows can save Valley Stream homeowners $283+ each year after replacing single-pane windows.
The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are completely 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?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. Because these installations are more involved, they will increase overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
Your window installation company will be able to advise you on the best type for your project. In Valley Stream, the decision will mostly be influenced by the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Valley Stream
EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. We’ve evaluated the best window replacement companies in Valley Stream 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 have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Valley Stream area so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Valley Stream’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Valley Stream window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Valley Stream, NY Window Replacement FAQs
How much should window installation cost?
The average cost of replacing one window ranges from $450 to $650. There are many factors that influence the price, such as your property’s location, the number of windows, styles and sizes of windows, the materials used in designing the windows, local labor costs and how energy-efficient the windows are.
What are the most common types of replacement windows?
There are various types of windows you can get for your house, including picture windows, casement windows, double-hung and single-hung windows, transom windows, bay windows, slider windows and awning windows.
What services do window replacement companies provide?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all of the windows at once is the only way to gain that benefit. However, if you have just one or two windows that are damaged or drafty, you can replace just those.
