How Installing Energy-Efficient Windows in Riverhead Saves You Money
When you upgrade to energy-efficient windows, you may see a few benefits, such as:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- 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.
- Save money on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $215 annually on your energy bills in Riverhead.
Estimated Cost of Window Replacement in Riverhead
Let's take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Even though the average to replace one window is around $600, it can range anywhere from $200 to $1,200. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.
It's also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that switching out the windows on your Riverhead home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We advise getting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has noticeable deterioration. Full-frame installations are more involved and will raise the overall cost. 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 won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Riverhead, the decision will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Riverhead
In our hunt to make your home improvements easier and more eco-friendly in Riverhead, EcoWatch assessed many companies before deciding on these. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Riverhead, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Riverhead.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, quality of installation, professionalism, quality of parts and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is well protected. Window installation companies with 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 a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Riverhead, NY Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
Can I replace my own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or skills, we recommend getting a professional to do it for you.
What time of year should I replace my windows?
Although you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, it shouldn't be raining, because rain can make the installation more difficult.
Should I replace my windows all at the same time?
If you're upgrading your windows to save on your energy bills, replacing all the windows together is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or leaky, you can replace just those.
