Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's energy efficiency can also have a large impact on home energy conservation. If your house has traditional, outdated windows, your AC or heating system could be working overtime to heat or cool your house. This means spending more on electricity bills.
Installing efficient windows on your property can help you save money every month on your energy bills — and you can help the environment as well.
So if you're constructing a new home, renovating or updating your windows in Smithtown, this guide is the best place to get started.

How Installing Energy-Efficient Windows in Smithtown 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 benefit you:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save on electricity bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Smithtown, that's about 307 pounds per year on average.
Estimated Cost of Window Replacement in Smithtown
Each window installer offers various services and has different price points based on a few factors.
How Much Do New Windows Cost?
According to our research, the national average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is due to the fact that the cost of window installations are based 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.
It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Smithtown homeowners $437+ a year when replacing single-pane windows.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're not sure which type of window installation service you need, your installer should be able to 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 Smithtown
EcoWatch reviews are different from most reviews because we evaluate these companies through a sustainability lens. We have assessed the best window installers in Smithtown mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Smithtown, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Smithtown.
Work Quality
When choosing new windows, the quality and breadth 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 customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, warranty, professionalism, quality of parts, cost and more.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Smithtown's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Smithtown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Smithtown, NY Window Replacement FAQs
How much does window installation cost?
The national average cost to install a window is around $600 but can range between $200 and $1,200, depending on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the different kinds of windows?
The most common types of windows for homes include: double-hung and single-hung windows, picture windows, slider windows, awning windows, casement windows, bay windows and transom windows.
Do I really need to use a window installation company?
You should use a window installation professional whenever you want new windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best left to the professionals.
How long does window installation generally take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
Should I replace my windows all at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
