How Installing Energy-Efficient Windows in Montville Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- 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 harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Montville
When researching window installation, each company offers varying services and costs. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
Typically, homeowners in Montville can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. These estimates vary depending on specific characteristics of your installation, like number of windows, size, the location of your home, type, material and more.
It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Montville home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step when considering a window replacement is to think about whether you should get a full-frame or pocket installation.
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 additional materials, like insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window replacement company will be able to help you choose what’s best for your needs. In Montville, the decision will mostly depend on the age of your home and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Montville
The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. We have reviewed the best window installation companies in Montville mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Montville, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Montville.
Work Quality
When installing 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 get. 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
We analyzed patterns in recent customer feedback to find 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 warranty, quality of installation, quality of parts, professionalism, cost and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Montville’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Montville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Montville, NJ Window Replacement FAQs
What is the average cost to install new windows?
The typical cost of replacing a single window can range from $450 to $650. There are several factors that affect how much it costs, including the materials used in designing the windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are, your property’s location and the number of windows.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your house, including awning windows, transom windows, slider windows, bay windows, double-hung and single-hung windows, picture windows and casement windows.
Can you replace your own windows?
If you’re handy and have experience with similar home improvement projects, it’s possible to install your own windows. However, if you don’t have the time or experience, we recommend getting a professional to do it for you.
How do you know it’s time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows together is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
