How Installing Energy-Efficient Windows in Monrovia Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could help you:

  • Save on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
  • Reduce your carbon footprint: In Monrovia, you can cut your indirect greenhouse gas emissions by about 117 pounds per year when you upgrade to energy-efficient windows.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Monrovia

When researching window installation, each company provides varying services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

According to our market research, the national average cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost varies based on several factors, like size, the location of your home, type, number of windows, material and more.

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 installing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

There are typically two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has significant rot or deterioration. These installations are more involved and will increase the overall cost. Pocket installations are simpler and won’t carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Monrovia

In our hunt to find the most reliable, eco-friendly window installers in Monrovia, the EcoWatch Reviews team evaluated many companies before deciding on these. We have decided to assess the best window replacement companies in Monrovia mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to 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 a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

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

Monrovia, CA Window Replacement FAQs

How much does window installation cost?

The national average cost to replace a single window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is generally 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 upfront but can save you hundreds of dollars a year in energy bills.

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 don’t open are more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installers cover the entire process — from replacing your old windows with brand-new ones to cleaning up after the installation. In addition, many companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, the weather should be dry, as rain can make the installation harder.

Should I replace my windows all at the same time?

If you’re upgrading your windows to get more efficient windows, replacing all of your windows at the same time is the only way to gain that benefit. However, if you have only a few windows that are damaged or drafty, you can replace just those.
