How Installing Energy-Efficient Windows in Essex Saves You Money

When you switch to energy-efficient windows, you may see several perks, such as:

  • More efficient energy usage in your home: Because the winters can get very cold in Essex, homeowners usually depend on their heater during that time. Energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your home warm.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Essex

When considering window installation, each company provides varying services and costs. Let's take a look at some average costs and services.

How Much Do New Windows Cost?

Although the typical to replace a single window is around $600, it can range anywhere from $200 to $1,200. But costs will vary considerably based on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $403 a year on your energy bills in Essex.

Another factor that influences the overall cost is the material you select for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as 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 replacements, there are typically two kinds that your provider will have: full-frame and pocket installations.

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're still trying to decide which type of installation you need, you can ask your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Essex

EcoWatch reviews differ from most reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Essex and ranked them using the following methodology:

Service Area

Because this is a guide for Essex, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Essex.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, quality of installation, quality of parts, warranty, cost and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Essex's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Essex window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Essex, CT Window Replacement FAQs

How much does window installation cost?

The typical cost of replacing a window can range between $450 and $650. There are several factors that affect how much it costs, including your property's location, styles and sizes of windows, the number of windows, local labor costs, how energy-efficient the windows are and the materials used in designing the windows.

What are the different types of windows?

The most common types of windows for homes include: awning windows, casement windows, double-hung and single-hung windows, transom windows, slider windows, picture windows and bay windows.

Can I install my own windows?

While you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.

What time of year is a good time to replace my windows?

Although you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.
