Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Lloyd Harbor Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

  • Better temperature control in your home: When you live in a place like Lloyd Harbor where the winters can be very cold, you usually have to depend on your heater to keep your house warm. Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.
  • More efficient energy use in your home: In Lloyd Harbor where the summers can be quite hot, energy-efficient windows reduce the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Lloyd Harbor

Windows come in various styles, shapes and purposes, so costs and services will differ tremendously depending on your project. Below, we describe the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Generally, Lloyd Harbor homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at about $600. This is due to the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lloyd Harbor homeowners $215+ each year after replacing single-pane windows.

Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step when considering a window replacement is to think about whether you want a full-frame or pocket installation.

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. 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 will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're unsure which kind of window installation service you need, your installer can help you out. Generally, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lloyd Harbor

EcoWatch is different from most reviewers since we assess these companies through a sustainability lens. We have assessed the best window replacement companies in Lloyd Harbor mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Lloyd Harbor, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Lloyd Harbor.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

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 most important factor, as it indicates the quality of services across most other categories, including quality of parts, warranty, professionalism, cost, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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