How Installing Energy-Efficient Windows in Hauppauge Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:

• Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
• Save money on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save around $215 annually on your energy bills in Hauppauge.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Hauppauge

Each window installer provides various services and has varying price points based on a few factors.

How Much Do New Windows Cost?

Typically, homeowners in Hauppauge can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at around $600. This is due to the fact that window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that influences the overall cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because 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?

When it comes to window installations, in general there are two types that your provider will offer: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage or rot. These installations are more involved and will increase the total cost. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Hauppauge

EcoWatch reviews are different from other reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Hauppauge and ranked them using the following methodology:

Service Area

Because this is a guide for Hauppauge, we gave more points to companies that serve the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Hauppauge.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, warranty, cost, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Hauppauge’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Hauppauge window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
