How Installing Energy-Efficient Windows in Denville Saves You Money
Switching to energy-efficient windows can help 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:
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Save money on electricity bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $287 annually on your energy bills in Denville.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Denville
Windows come in varying purposes, shapes and styles, so costs and services will differ greatly depending on your project. Below, we go over the average cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
According to our market research, the typical cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $287 a year on your energy bills in Denville.
Another factor that affects the total cost is the material you select for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the total window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re unsure which type of window installation service you should get, your installer should be able to assist you. In general, the choice depends on 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 Denville
EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:
Service Area
Because this is a guide for Denville, we paid more attention to companies that provide services to the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Denville.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Denville’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Denville window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Denville, NJ Window Replacement FAQs
What is the typical cost to replace windows in a home?
The typical cost of installing a window can range from $450 to $650. There are a variety of factors that affect how much it costs, including the number of windows, the materials used in designing the windows, local labor costs, your property’s location, styles and sizes of windows and how energy-efficient the windows are.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies provide?
Window installation companies cover the entire process — from replacing old windows with brand-new ones to cleaning up afterward. Additionally, some companies offer window manufacturing, customization and repairs.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it’s probably time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
