20 Best Window Companies in Jefferson, NJ (2025 Reviews)

How Installing Energy-Efficient Windows in Jefferson Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows 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• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
• Decrease your carbon footprint: In Jefferson, you can reduce your indirect greenhouse gas emissions by about 206 pounds per year after you install energy-efficient windows.
• Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.

Estimated Cost of Window Replacement in Jefferson

When looking into window installation, each company provides varying services and prices. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Jefferson can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost varies based on several factors, such as the location of your home, material, size, number of windows, type and more.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Jefferson homeowners $287+ per year after replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When it comes to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installation company should be able to help you choose what’s best for your needs. In Jefferson, the decision will mostly depend on how old your home is and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional check on your frames and window sills.

Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Jefferson so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, cost, warranty and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as 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. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. 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.
