Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a considerable impact on home energy conservation. When it’s the middle of winter, your outdated and leaky windows could be making your home harder to heat and costing you more in power bills.
That’s also bad for the environment because the extra energy required by damaged windows increases your carbon footprint.
Unlike other sites, EcoWatch ranks window installation companies based on energy efficiency while also factoring in cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Bernards Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to make the switch:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Save money on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your home.
- Reduce your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Bernards
Windows come in various shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
On average, Bernards homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at approximately $600. This is because the cost of window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $308 a year on your energy bills in Bernards.
Getting free quotes from multiple companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first step when considering a window replacement is to clarify whether you want a full-frame or pocket installation.
A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
If you’re still trying to decide which kind of installation you need, you can talk to your provider and get their recommendation. The choice mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Bernards
In our search to find the most reliable, eco-friendly window installers in Bernards, the EcoWatch Reviews team assessed many companies before deciding on these. We’ve assessed the best window replacement companies in Bernards mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Bernards, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Bernards.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good things to say about their experience with a certain installer, 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 as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
