How Installing Energy-Efficient Windows in Chatham Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could benefit you:
- Save money on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Chatham
When researching window installation, each company provides different services and costs. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
On average, Chatham homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at around $600. These numbers vary based on specific characteristics of your installation, like number of windows, type, the location of your home, size, material and more.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $287 a year on your energy bills in Chatham.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies offer: full-frame and pocket installations.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. 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 damage or rot, you will most likely need a full-frame installation instead.
If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Chatham, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Chatham
The EcoWatch Reviews team differs from most reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Chatham, we paid more attention 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 Chatham.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, warranty, quality of parts, quality of installation, cost and more.
Cost
Cheaper windows don’t necessarily 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 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Chatham, NJ Window Replacement FAQs
What is the average cost to install windows?
The national average cost to install one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
You should use a window installation company whenever you need to replace your windows. Installing windows is a complex process that can take a lot of time, so it’s best handled by the professionals.
Should I replace my windows all at once?
If you’re upgrading your windows to get more efficient windows, replacing all your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
