How Installing Energy-Efficient Windows in Warwick Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, such as:
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Warwick, that’s about 286 pounds per year on average.
- Save on energy bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $308 annually on your energy bills in Warwick.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Warwick
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 installers.
How Much Do New Windows Cost?
On average, homeowners in Warwick can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Warwick homeowners $308+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two types that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company will be able to help you understand what’s best for your needs. In Warwick, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Warwick
In our search to find the most reliable, eco-friendly window installers in Warwick, EcoWatch landed on the above companies as the top window installation companies in the city. We have assessed the top window replacement companies in Warwick mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Warwick, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Warwick.
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 make sure its technicians are well-qualified and that the company has gotten lots 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 service from a certain installer, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Warwick’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Warwick window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Warwick, PA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a window is about $600 but can range from $200 to $1,200, based on several factors. The price is generally dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
A window’s energy efficiency is influenced by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installers do?
Window installers cover the entire process — from replacing old windows with brand-new ones to cleaning up afterward. In addition, many companies offer window manufacturing, customization and repairs.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
How long does it take to install windows?
Because a window takes about 30 minutes to install, around 16 windows can be installed during an 8-hour work day.
