How Installing Energy-Efficient Windows in Rosemead Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Rosemead
When considering window installation, each company offers different services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the national average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. This is because window installations depend on several 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.
It’s also worth noting that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Rosemead home translates to an average energy savings of $236 to $319 each 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 upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Rosemead
In our hunt to find the most reliable, eco-friendly window installers in Rosemead, the EcoWatch Reviews team assessed dozens of companies before settling on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Rosemead so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, warranty, cost, quality of installation, quality of parts and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure 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. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Rosemead’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Rosemead window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Rosemead, CA Window Replacement FAQs
What is the typical cost to replace windows?
The typical cost of replacing a single window can range from $450 to $650. There are several factors that influence how much it costs, which include the number of windows, styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows, your property’s location and local labor costs.
What type of window is the most energy-efficient?
A window’s energy efficiency is affected by a variety 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.
When should I use a window installation company?
Unless you’re handy and have all the tools you need to replace your own windows, we recommend hiring the pros. The window installation process is complex and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
How do you know it’s time to replace your windows?
Windows usually last 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them checked by an expert to determine if they are in need of a repair or replacement.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it’s probably time to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
