Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a considerable impact on home energy conservation. Outdated windows can cost you in power bills. As a matter of fact, the Department of Energy estimates that 25-30% of your house's heat or cool air could be lost through your windows.
Replacement windows improve the insulation in your home, not only making you more comfortable during extreme temperatures, but also saving you money and helping the environment.
So if you're building a new home, renovating or replacing your windows in Alexandria, you've found the best place to get started.

How Installing Energy-Efficient Windows in Alexandria Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Better temperature control in your home: When you reside in a place like Alexandria where the winters can be very cold, you often have to rely on your heater to keep your home warm. Energy-efficient windows can reduce how hard your heater needs to work to heat your home.
- Save on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your investment: The older your home is, the more likely it is that getting new 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way.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 property if you decide to sell.
Estimated Cost of Window Replacement in Alexandria
Let's go over the cost of installing new windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
On average, homeowners in Alexandria can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost you varies depending on several factors, such as number of windows, size, type, the location of your home, material and more.
It's also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your Alexandria home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material you want for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
If you're still trying to decide which type of installation you should get, you can consult with your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Alexandria
EcoWatch reviews are different from other reviews since we evaluate these companies through a sustainability lens. We've assessed the top window installers in Alexandria mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Alexandria, we only included companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Alexandria.
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 of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have positive things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, 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. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Alexandria, NJ Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the kinds of windows?
The most common types of windows for homes are casement windows, awning windows, double-hung and single-hung windows, bay windows, slider windows, picture windows and transom windows.
Can you replace your own windows?
While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How often do you need to replace your windows?
Windows usually last 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to determine if they need any repairs or replacements.
