How Installing Energy-Efficient Windows in Seaford Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to make the switch:

• 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.
• Reduce your carbon footprint: In Seaford, you can cut your indirect greenhouse gas emissions by about 307 pounds per year when you install energy-efficient windows.
• 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
• Save on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save around $283 annually on your energy bills in Seaford.

Estimated Cost of Window Replacement in Seaford

Let’s go over the cost of replacing your windows and the types of services offered by installers.

How Much Do New Windows Cost?

Typically, homeowners in Seaford can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. This is because window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and light, but they provide 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 as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation entails installing a new window without replacing the frame. So, instead of removing the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which type of window installation service you need, your installer should be able to assist you. In general, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Seaford

In our hunt to make your home improvements easier and more eco-friendly in Seaford, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Seaford and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Seaford, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Seaford.

Work Quality

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

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installation companies won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a wide 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

Because of Seaford’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Seaford window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
