How Installing Energy-Efficient Windows in Lansdowne Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could benefit you:

  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 376 pounds.
  • Save money on energy bills: Because energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save about $353 annually on your energy bills in Lansdowne.
  • Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Lansdowne

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

How Much Do New Windows Cost?

According to our market research, the average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. These amounts are based on specific characteristics of your installation, including type, size, material, the location of your home, number of windows and more.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lansdowne homeowners $353+ each year after replacing single-pane windows.

How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are solid 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?

When considering window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the trim, sill and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage or rot. These installations are more involved and will raise the total cost. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

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

How We Choose the Best Window Installers in Lansdowne

EcoWatch reviews differ from other reviews, as we evaluate these companies through a sustainability lens. We have decided to assess the top window installation companies in Lansdowne primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Lansdowne so you can find a quality window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, cost, quality of installation, professionalism, warranty 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 providers’ prices, we awarded 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 make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Lansdowne, VA Window Replacement FAQs

What is the typical cost to install windows?

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

Which kind of window is the best?

A window’s energy efficiency is influenced by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified 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 installer. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.

What time of year should I replace my windows?

While you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, because rain can make the installation harder.

How do you know it’s time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
