How Installing Energy-Efficient Windows in Trenton Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save money on energy bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $394 annually on your energy bills in Trenton.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 65 pounds.
Estimated Cost of Window Replacement in Trenton
When looking into window installation, each company provides different services and prices. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
On average, homeowners in Trenton can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But costs will differ significantly depending on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
We recommend getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
If you're still trying to decide which kind of installation to get, you can ask your installer and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Trenton
In our hunt to find the most reliable, eco-friendly window installers in Trenton, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured in our guide to ensure its contractors 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 very important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies won't always provide the most quality service. Still, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a substantial 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
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Trenton, NY Window Replacement FAQs
How much should window installation cost?
The national average cost to replace one window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
The most common types of windows for homes include: double-hung and single-hung windows, casement windows, bay windows, transom windows, awning windows, picture windows and slider windows.
Can I install my own windows?
Even though it is possible to install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
When is it time to replace your windows?
Windows usually have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to see if they need any repairs or replacements.
Should I replace all my windows at once?
If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
