How Installing Energy-Efficient Windows in Essex Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.
- Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Essex
When researching window installation, each company provides varying services and costs. Let’s look at some average costs and services.
How Much Do New Windows Cost?
Generally, Essex homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost varies depending on several factors, including the location of your home, size, type, material, number of windows and more.
Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $285 a year on your energy bills in Essex.
Another factor that affects the total cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window installations, in general there are two types that your provider will offer: full-frame and pocket installations.
A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations are simpler and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re still trying to decide which kind of installation to get, you can talk to your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Essex
The EcoWatch Reviews team differs from other reviewers, as we look at these companies through a sustainability lens. We’ve decided to assess the top window installation companies in Essex mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Essex, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Essex.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, quality of parts, professionalism, quality of installation, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a range 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
