How Installing Energy-Efficient Windows in Monrovia Saves You Money

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

  • Better temperature control in your home: Residing in a chilly place like Monrovia can often mean depending on your heater to keep your house cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save $509 a year on your bills.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.

Estimated Cost of Window Replacement in Monrovia

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

How Much Do New Windows Cost?

Generally, homeowners in Monrovia can expect that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at about $600. How much it will cost you varies depending on several factors, including size, type, the location of your home, material, number of windows and more.

Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Another factor that affects the total cost is the material you choose for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a replacement is to clarify whether you want a full-frame or pocket installation.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Monrovia

EcoWatch reviews are different from other reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

Service Area

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

Work Quality

When choosing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher 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 highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, warranty, cost, professionalism, quality of parts and more.

Cost

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

Warranty

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Monrovia, CA Window Replacement FAQs

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

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

What type of window is the best for energy efficiency?

A window's energy efficiency depends on a number of 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?

Although you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.

Should I replace all my windows at the same time?

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