How Installing Energy-Efficient Windows in East Northport Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, such as:
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 307 pounds.
Estimated Cost of Window Replacement in East Northport
Let's go over the cost of replacing your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Although the typical of installing one window is around $600, it can range from $200 to $1,200. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will make your project cost more.
It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save East Northport homeowners $215+ a year when replacing single-pane windows.
Something else that affects the overall cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as 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?
Generally, there are two kinds of window installation services companies offer: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the entire window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window within its 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 not sure which type of window installation service you should get, your installer can advise you. In general, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in East Northport
In our hunt to find the most reliable, eco-friendly window installers in East Northport, EcoWatch examined many companies before deciding on these. Along with energy efficiency, we evaluated several window installers in East Northport and ranked them using the following methodology:
Service Area
Since this is a guide for East Northport, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in East Northport.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, warranty, cost, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Can you install your own windows?

When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
