How Installing Energy-Efficient Windows in Deer Park Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 307 pounds per year on average.
- Better temperature control in your home: Energy-efficient windows can lower the amount of cool air lost through your windows when cooling your home.
- Better temperature control in your home: When you reside in a place like Deer Park where the winters can get very cold, you often need to rely on your heater to keep your home warm. Energy-efficient windows can lower how hard your heater needs to work to heat your home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Deer Park
Windows come in different shapes, styles and purposes, so costs and services will vary greatly depending on your project. Below, we detail the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost is based on several factors, like number of windows, the location of your home, type, material, size and more.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Deer Park homeowners $215+ a year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations entail replacing the full window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage or rot. Because full-frame installations are more involved, they will increase the total cost. A pocket installation entails installing a new window without replacing the frame. So, instead of tearing out the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're not sure which kind of window installation service you should get, your installer can assist you. Generally, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Deer Park
In our hunt to find the most reliable, eco-friendly window installers in Deer Park, the EcoWatch Reviews team evaluated many companies before landing on these. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Deer Park so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. 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
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Deer Park, NY Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically 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 hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring the pros. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
When is it time to replace your windows?
Windows usually have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
