How Installing Energy-Efficient Windows in Warren Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 206 pounds per year on average.
- Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Warren
Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the typical costs and the primary services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in Warren can expect that most window installations will range from $250 to $1,200, with the average cost sitting at about $600. But prices differ remarkably 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 make your project cost more.
Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Asking for free quotes from several providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has significant deterioration. With this service, your installers will replace the entire window, including the sill, trim and frame. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Warren
In our hunt to make your home improvements easier and more eco-friendly in Warren, the EcoWatch Reviews team examined dozens of companies before settling on these. We’ve decided to evaluate the best window installers in Warren mainly 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 cut your power 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 Warren, we paid more attention to companies that cover 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 Warren.
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 company in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with 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 want to keep costs low when possible. When analyzing providers’ prices, we gave higher scores 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Warren, NJ Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost to replace a window can range between $450 and $650. There are several factors that influence how much it costs, such as local labor costs, how energy-efficient the windows are, the materials used in designing the windows, your property’s location, styles and sizes of windows and the number of windows.
What are the kinds of windows?
The most common types of windows for homes include: picture windows, casement windows, awning windows, slider windows, double-hung and single-hung windows, transom windows and bay windows.
Can I install my own windows?
If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don’t have the time or experience, we recommend hiring a professional.
Should I replace my windows all at once?
If you’re upgrading your windows because of energy-efficiency, replacing all your windows together is the only way to see a noticeable difference. However, if you have just one or two windows that are damaged or leaky, you can replace just those.
