Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's efficiency can also have a big impact on home energy conservation. When it's the middle of winter, your outdated and drafty windows could be making your home more difficult to heat and more uncomfortable for you.
That's also bad news for the environment, as the additional energy used by leaky windows increases your carbon footprint.
So if you're constructing a new home, renovating or changing out old windows in Mattituck, you've found the best place to get started.

How Installing Energy-Efficient Windows in Mattituck Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:
- Better temperature control in your home: When you reside in a city like Mattituck where the summers can get quite hot, you usually have to depend on your air conditioner to keep your house cool. Energy-efficient windows can decrease the amount of cool air lost through your windows when cooling your home.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Mattituck, that's about 307 pounds per year on average.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
- Better temperature control in your home: Living in a very cold place like Mattituck can often mean relying on your heater to keep your home cool. Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
Estimated Cost of Window Replacement in Mattituck
When researching window installation, each company offers different services and prices. Let's go over some typical costs and services.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range from $200 to $1,200. But costs will vary significantly based on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Mattituck homeowners $215+ each year after replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you choose. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has a lot of deterioration. With this service, your professionals will replace the total window, including the frame, trim and sill. A pocket installation involves installing a new window within the existing frame. So, instead of removing the whole window and reinstalling it, the window 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 understand what's best for your needs. In Mattituck, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Mattituck
EcoWatch reviews are different from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Mattituck, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Mattituck.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Mattituck's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Mattituck window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Mattituck, NY Window Replacement FAQs
How much should a window install cost?
The typical cost to replace one window ranges between $450 and $650. There are many factors that affect how much it costs, which include your property's location, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows and local labor costs.
What are the different kinds of windows?
There are various kinds of windows you can get for your house, such as bay windows, transom windows, double-hung and single-hung windows, slider windows, picture windows, awning windows and casement windows.
What do window installers do?
Window installation professionals visit your house to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
