How Installing Energy-Efficient Windows in Westwood Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, including:
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Westwood
Each window replacement company offers varying services and has varying price points based on a few factors.
How Much Do New Windows Cost?
Although the typical cost to replace a single window is about $600, it can range from $200 to $1,200. But prices vary 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.
It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Westwood homeowners $285+ a year when replacing single-pane windows.
Getting free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step of an installation is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the full window, including the frame, trim and sill. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Westwood, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Westwood
The EcoWatch Reviews team differs from other reviewers, as we evaluate these companies through a sustainability lens. We’ve reviewed the best window installation companies in Westwood 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 electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Westwood, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Westwood.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain installer, it won’t be 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
As discussed previously, windows are a sizable 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 Westwood’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Westwood window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Westwood, NJ Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing a window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
Can I replace my own windows?
If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. But if you don’t have the time or know-how, we don’t recommend it.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
How often should you replace your windows?
Windows typically have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have an expert take a look at them to see if they need any repairs or replacements.
