How Installing Energy-Efficient Windows in Ellicott City 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 switch include the following:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Ellicott City, that’s about 249 pounds per year on average.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that amount, which helps you save $289 a year on your bills.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Ellicott City

Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

According to our research, the average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will make your project cost more.

Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Another factor that influences the total cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when considering a window installation is to figure out whether you need a full-frame or pocket installation.

Full-frame installations entail replacing the full window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage. These installations are more involved and will raise the total cost. A pocket installation involves replacing a window within the existing frame. So, instead of taking out the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which type of window installation service you should get, your installer can help you out. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Ellicott City

EcoWatch reviews differ from most reviews, as we evaluate these companies through a sustainability lens. We have decided to assess the best window installation companies in Ellicott City mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Ellicott City area so you can find the best window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company on this list to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction. 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 installation, quality of parts, warranty, professionalism and more.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
