Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Herndon Saves You Money

When you upgrade to energy-efficient windows, you may see several benefits, including:

  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way.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 increase the value of your property if you decide to sell.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Herndon

Windows come in various purposes, styles and shapes, so costs and services will differ tremendously depending on several factors. Below, we go over the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Generally, Herndon homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at around $600. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.

Whether or not you choose 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 $356 a year on your energy bills in Herndon.

Getting free quotes from several providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage. Because these installations are more involved, they will raise overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re not sure which type of window installation service you should get, your installer can assist you. Typically, the choice is influenced by 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 Herndon

In our search to make your home improvements easier and more eco-friendly in Herndon, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:

Service Area

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

Work Quality

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

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive things to say about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Herndon, VA Window Replacement FAQs

What is the typical cost to install new windows?

The average cost of installing a single window ranges from $450 to $650. There are many factors that influence the price, such as the materials used in designing the windows, your property’s location, local labor costs, styles and sizes of windows, how energy-efficient the windows are and the number of windows.

What are the different types of windows?

There are several different kinds of windows you can get for your house, such as awning windows, bay windows, slider windows, casement windows, double-hung and single-hung windows, picture windows and transom windows.

Do you really need to use a window installation company?

Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.

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

While you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, it shouldn’t be raining, because rain can make the installation more difficult.

How long does it usually take to install windows?

Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
