Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Whether you're doing home renovations or have old windows, windows play a key role in conserving your home's electricity. If your house has traditional, outdated windows, your HVAC system could be working extra hard to heat or cool your home. This means higher electricity bills.

That's also bad for the environment, as the additional energy used by outdated windows increases your carbon footprint.

Unlike other review sites, EcoWatch ranks window companies based on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Smithtown Saves You Money

When you switch to energy-efficient windows, you may see some perks, such as:

  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • More efficient energy usage in your home: Because the summers can get quite hot in Smithtown, homeowners usually depend on their air conditioner a lot. Energy-efficient windows decrease how much cool air is lost through your windows, making it easier to keep your house cool.
  • More efficient energy usage in your household: In Smithtown where the winters can get very cold, energy-efficient windows reduce how much heat is lost through your windows, which makes it easier to keep your home warm.
  • 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

Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost depends on several factors, such as number of windows, the location of your home, material, size, type and more.

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 $215+ 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.

What services do window installation companies provide?

Window installation professionals visit your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
