Why you can trust EcoWatch

No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home’s energy efficiency can also have a considerable impact on home energy conservation. Drafty or leaky windows can make your AC or heater work extra hard in the summer or winter.

Replacement windows improve your home’s insulation, not only making you more comfortable during extreme temperatures, but also saving you money and helping the environment.

Efficient windows are of particular importance in Merrifield, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $359 per year.

How Installing Energy-Efficient Windows in Merrifield Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:

  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Merrifield, that’s about 324 pounds per year on average.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Merrifield

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

How Much Do New Windows Cost?

On average, Merrifield homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at approximately $600. But prices 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 replacements, which will make your project cost more.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $359 a year on your energy bills in Merrifield.

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

In general, there are two types of window installation services you can get: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Merrifield, the choice will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Merrifield

In our search to make your home improvements easier and more eco-friendly in Merrifield, the EcoWatch team examined dozens of companies before deciding on these. We’ve reviewed the top window installers in Merrifield mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Merrifield, we only included companies that cover the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Merrifield.

Work Quality

When choosing 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 of window 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

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including warranty, quality of parts, cost, professionalism, quality of installation and more.

Cost

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

Warranty

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

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Merrifield, VA Window Replacement FAQs

What is the typical cost to replace windows?

The average cost of installing one window can range from $450 to $650. There are several factors that affect the price, which include your property’s location, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows and local labor costs.

What type of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.

Do I really need to use a window installation company?

Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on energy costs, replacing all of your windows together is the only way to gain that benefit. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
