How Installing Energy-Efficient Windows in Deer Park Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, including:
- Save on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $215 annually on your energy bills in Deer Park.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 307 pounds.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Deer Park
Let’s take a look at the cost of updating your windows and the types of services offered by installers.
How Much Do New Windows Cost?
Generally, homeowners in Deer Park can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost is based on several factors, such as the location of your home, number of windows, type, size, material 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 Deer Park homeowners $215+ each year after replacing single-pane windows.
Something else that affects the overall cost is the material of the frame you select. Aluminum frames are usually 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 offer 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 typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage or rot. These installations are more involved and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. So, instead of removing the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Deer Park
EcoWatch differs from most reviewers since we’re examining these companies through a sustainability lens. Along with energy efficiency, we analyzed 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 selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks 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 the majority of customers don’t have nice things to say about their service from a certain installer, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Deer Park’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Deer Park window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Deer Park, NY Window Replacement FAQs
How much should a window install cost?
The typical cost to replace a single window ranges from $450 to $650. There are a variety of factors that influence the price, such as the number of windows, how energy-efficient the windows are, your property’s location, styles and sizes of windows, the materials used in designing the windows and local labor costs.
What are the most common types of replacement windows?
There are several different types of windows you can get for your house, including picture windows, casement windows, awning windows, double-hung and single-hung windows, transom windows, slider windows and bay windows.
Can I replace my own windows?
While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does window installation usually take?
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 have a lot of windows that need to be installed.
