Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. 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.

Whether you're updating for style or have old windows, windows play a key role in conserving electricity in your home. Traditional, outdated windows can cost you in energy bills. As a matter of fact, the Department of Energy estimates that 25-30% of your home's heat or cool air could be lost through your windows.

That's also bad news for the environment, as the extra energy used by drafty windows increases your carbon footprint.

Efficient windows are especially important in Old Jamestown, 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 $376 a year.

How Installing Energy-Efficient Windows in Old Jamestown Saves You Money

When you switch to energy-efficient windows, you may see several perks, including:

  • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 763 pounds per year on average.
  • 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. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Old Jamestown

Let's take a look at the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

Typically, Old Jamestown homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at approximately $600. This is due to the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Another factor that affects the total cost is the material you select for your frame. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Old Jamestown, the decision will mostly be based on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Old Jamestown

In our search to find the most reliable, eco-friendly window installers in Old Jamestown, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Old Jamestown and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Old Jamestown so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, warranty, quality of installation, professionalism, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

Due to Old Jamestown's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Old Jamestown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Old Jamestown, MO Window Replacement FAQs

What is the average cost to install new windows?

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

What type of window is the best for energy efficiency?

A window's energy efficiency is influenced by a variety of 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 since they are certified by the U.S. Department of Energy.

What do window installers do?

Window installation professionals go to your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

How long does it take to install windows?

Since the average installation time is 30 minutes per window, about 16 windows can be installed during an 8-hour work day.

Should I replace all my windows at once?

If you're upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
