Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's energy efficiency can also have a considerable impact on home energy conservation. During the cold winter months, the last thing you want is your heat to leak out of your drafty windows.
That's also bad for the environment because the extra energy used by damaged windows increases your carbon footprint.
Unlike other sites, EcoWatch ranks window replacement companies on energy efficiency while also considering cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Sussex Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- More efficient energy usage in your household: Because the summers can get pretty warm in Sussex, homeowners often depend on their air conditioner during that time. Energy-efficient windows decrease the amount of cool air that is lost through your windows, making it easier to keep your house cool.
- Save on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Sussex
When researching window installation, each company provides different services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
Generally, homeowners in Sussex can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These estimates vary depending on the specifics of your installation, such as the location of your home, material, number of windows, size, type and more.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Sussex homeowners $483+ a year after replacing single-pane windows.
We advise getting free quotes from multiple window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. Full-frame installations are more involved and will increase the total cost. A pocket installation entails replacing a window within the old frame. So, instead of removing the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which kind of installation you need, you can talk to your installer and get their recommendation. The decision 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 Sussex
EcoWatch reviews are different from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Sussex and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Sussex, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Sussex.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, professionalism, quality of installation, cost, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window companies won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Sussex's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Sussex window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Sussex, WI Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost to replace a window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the different kinds of windows?
The most common types of windows for homes are bay windows, picture windows, double-hung and single-hung windows, slider windows, awning windows, transom windows and casement windows.
Can I replace my own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
