Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. According to the Department of Energy, heat or cool air lost through traditional, outdated windows could represent 25-30% of household energy climate control costs.

Installing upgraded, efficient windows on your house can help you save money each month on your power bills — and you can help the environment as well.

Unlike other review sites, EcoWatch ranks window installation companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Raritan Saves You Money

When you upgrade to energy-efficient windows, you may see a few benefits, such as:

  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Raritan, that's about 206 pounds per year on average.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient windows can help decrease that amount, which helps you save more on your bills.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Raritan

Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you'll find from the average window installation company.

How Much Do New Windows Cost?

Though the national average of installing one window is around $600, it can range from $200 to $1,200. This is due to the fact that window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Requesting free quotes from several companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

When considering window installations, there are generally two types that your provider will have: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation means replacing a window without removing the whole frame, which tends to be cheaper than a full-frame installation.

Your window replacement company should be able to help you understand what's best for your needs. In Raritan, the decision will mostly depend on the age of your home and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Raritan

In our hunt to find the most reliable, eco-friendly window installers in Raritan, EcoWatch examined many companies before settling on these. Along with energy efficiency, we reviewed several window installers in Raritan and ranked them based on the following methodology:

Service Area

Since this is a guide for Raritan, we only included companies that cover the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Raritan.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice feedback about their service from a certain installer, you won't see it featured on EcoWatch.

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 gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

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

Raritan, NJ Window Replacement FAQs

How much should a window install cost?

The national average cost to replace a window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which kind of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.

How do you know it's time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at once?

If you're upgrading your windows because of energy-efficiency, replacing all your windows together is the only way to gain that benefit. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
