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 aesthetics or have old windows, windows play a vital role in conserving energy in your home. Potential leaks or drafts can reduce your home’s energy efficiency by up to 30%, according to the Department of Energy. In Charter Oak, that’s almost $509 per year that you could save on your electric bills by making the switch.

That’s also bad news for the environment because the extra energy required by old windows increases your carbon footprint.

Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Charter Oak Saves You Money

When you upgrade to energy-efficient windows, you may see a few benefits, such as:

  • 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Charter Oak, that’s about 117 pounds per year on average.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Charter Oak

Each window replacement company offers varying services and has different costs based on several factors.

How Much Do New Windows Cost?

According to our market research, the typical cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. This is because window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

It’s also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Charter Oak home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat 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 companies offer: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of rot or deterioration. With this service, your professionals will replace the whole window, including the trim, sill and frame. Pocket installations are simpler and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you’re still trying to decide which type of installation you should get, you can talk to your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Charter Oak

In our hunt to find the most reliable, eco-friendly window installers in Charter Oak, the EcoWatch Reviews team evaluated many companies before landing on these. We have reviewed the top window installers in Charter Oak primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Charter Oak area so you can find the best window installation company near you.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer on this list to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have positive feedback about their service from a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Charter Oak, CA Window Replacement FAQs

How much does window installation cost?

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 generally influenced by the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What type of window is the best for energy efficiency?

A window’s energy efficiency depends on several factors, such as 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 and are certified by the U.S. Department of Energy.

Can I replace my 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 know-how, we don’t recommend it.

What time of year is a good time to replace my windows?

Replacement windows can be installed any time of the year, 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 home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.

How often should you replace windows?

Windows typically last 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have them looked at by an expert to see if they are in need of a repair or replacement.
