How Installing Energy-Efficient Windows in Lorton Saves You Money

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

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Decrease your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Lorton

Windows come in varying purposes, styles and shapes, so costs and services will differ greatly depending on several factors. Below, we go over the typical cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. 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 installations, which carry a higher price tag.

It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Lorton homeowners $359+ a year when replacing single-pane windows.

Asking for free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies provide: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are simpler and won’t carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

If you’re unsure which type of window installation service you need, your installer should be able to help you out. 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 Lorton

In our hunt to find the most reliable, eco-friendly window installers in Lorton, the EcoWatch team evaluated dozens of companies before landing on these. We have assessed the best window installation companies in Lorton mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When installing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you choose. 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 super important review factor. If most customers don’t have positive things to say about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Lorton, VA Window Replacement FAQs

What is the typical cost to replace windows in a home?

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

Which type of window should I get?

A window’s energy efficiency is affected by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I need to use a window installation company?

You should use a window installation company whenever you want to upgrade your windows. Installing windows is a complicated process that can take a lot of time, so it’s best handled by the professionals.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn’t be raining, since rain can make the installation more difficult.

How long does it take to install windows?

Each window takes about 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.
