How Installing Energy-Efficient Windows in Kent Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, such as:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
- 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 65 pounds per year on average.
Estimated Cost of Window Replacement in Kent
Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you’ll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. These figures are based on specific characteristics of your installation, such as size, number of windows, the location of your home, type, material and more.
It’s important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Kent homeowners $332+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installation company will be able to advise you on the best type for your project. In Kent, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Kent
In our search to make your home improvements easier and more eco-friendly in Kent, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including warranty, quality of installation, professionalism, cost, quality of parts 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 awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Kent’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Kent window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Kent, NY Window Replacement FAQs
How much should a window install cost?
The average cost of replacing a single window ranges from $450 to $650. There are a variety of factors that affect the price, including your property’s location, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows, local labor costs and the number of windows.
What are the different types of windows?
There are various types of windows you can get for your house, including transom windows, double-hung and single-hung windows, awning windows, casement windows, slider windows, bay windows and picture windows.
What services do window replacement companies offer?
Window installation companies cover the entire process — from replacing your old windows with brand-new ones to cleaning up afterward. Additionally, many companies offer window manufacturing, customization and repairs.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
