How Installing Energy-Efficient Windows in Winchester Saves You Money

There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

  • Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 376 pounds per year on average.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help decrease that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Winchester

When researching window installation, each company provides different services and costs. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

On average, homeowners in Winchester can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But costs differ 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 carry a higher price tag.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Winchester homeowners $351+ per year after replacing single-pane windows.

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

What Services do Window Installers Offer?

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

A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

If you’re still debating which type of installation to get, you can talk to your provider and get their advice. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Winchester

In our hunt to make your home improvements easier and more eco-friendly in Winchester, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We have evaluated the best window installers in Winchester 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 considers the following factors:

Service Area

Because this is a guide for Winchester, we paid more attention to companies that serve 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 Winchester.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included in our guide to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have nice things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily 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 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. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Winchester, VA Window Replacement FAQs

What is the typical cost to install new windows in a home?

The national average cost to replace a single window is about $600 but can range between $200 and $1,200, depending on several factors. The price is often influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the different kinds of windows?

The most common kinds of windows for homes include: casement windows, awning windows, transom windows, bay windows, picture windows, slider windows and double-hung and single-hung windows.

Can you replace your own windows?

If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or experience, we don’t recommend doing it on your own.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on energy costs, replacing all of your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.

How long does window installation generally take?

Each window takes about 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
