How Installing Energy-Efficient Windows in Trenton Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to consider making the switch:

• Save money on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating 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 Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: In Trenton, you can reduce your indirect greenhouse gas emissions by about 206 pounds per year after you install energy-efficient windows.

Estimated Cost of Window Replacement in Trenton

Let’s take a look at the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

Though the typical cost of replacing one window is about $600, it can range anywhere from $200 to $1,200. How much it will cost depends on several factors, such as number of windows, size, type, the location of your home, material and more.

It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Trenton homeowners $319+ a year when replacing single-pane windows.

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

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. A pocket installation involves replacing a window within the existing frame. This means instead of removing the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which type of window installation service you should get, your installer should be able to advise you. In general, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Trenton

In our search to find the most reliable, eco-friendly window installers in Trenton, EcoWatch chose the above companies as the best window installation companies in the city. We have assessed the top window replacement companies in Trenton mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Trenton, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Trenton.

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency 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

Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their service from a certain company, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded 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. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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