How Installing Energy-Efficient Windows in Westbury Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
• Decrease your carbon footprint: In Westbury, you can cut your indirect greenhouse gas emissions by about 307 pounds per year once you install energy-efficient windows.
• Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Westbury

Windows come in different styles, shapes and purposes, so costs and services will differ considerably depending on several factors. Below, we detail the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will add extra costs to your project.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Westbury homeowners $283+ each year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want a new style or your window has significant deterioration. With this service, your installers will replace the whole window, including the frame, trim and sill. Pocket installations are simpler and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

If you’re unsure which kind of window installation service you should get, your installer can assist you. In general, the decision depends on 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 Westbury

EcoWatch reviews are different from most reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Westbury and ranked them using the following methodology:

Service Area

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

Work Quality

When it comes to 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 you get. We do give window installers more points if they offer high-quality products, but we also consider 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 nice things to say about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, 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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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