How Installing Energy-Efficient Windows in Middle Island Saves You Money

There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:

  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
  • Save money on power bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, the switch can help you save about $215 annually on your energy bills in Middle Island.

Estimated Cost of Window Replacement in Middle Island

Windows come in varying styles, purposes and shapes, so costs and services will vary remarkably depending on several factors. Below, we go over the typical cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

On average, Middle Island homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. This is because of the fact that the cost of window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Middle Island homeowners $215+ a year when replacing single-pane windows.

Something else that affects the overall cost is the material of the frame you select. Aluminum frames are typically 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 provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves replacing a window without removing the whole frame, which is generally cheaper than a full-frame installation.

If you’re still trying to decide which type of installation you should get, you can ask your provider and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Middle Island

In our search to find the most reliable, eco-friendly window installers in Middle Island, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Middle Island area so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. 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

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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