How Installing Energy-Efficient Windows in Hillside Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:

• Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 206 pounds.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Hillside

Windows come in various shapes, purposes and styles, so costs and services will differ considerably depending on your project. Below, we describe the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. But prices differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will make your project cost more.

Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $290 a year on your energy bills in Hillside.

We recommend requesting free quotes from multiple window installers to find the one that works best for you.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

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

The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

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

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window 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

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, quality of installation, professionalism, cost, warranty and more.

Cost

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

Warranty

As discussed, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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