How Installing Energy-Efficient Windows in South El Monte Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
- Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Better temperature control in your home: Residing in a chilly place like South El Monte can often mean needing your heater to keep your house cool. Energy-efficient windows can lower how much heat is lost through your windows when heating your home.
Estimated Cost of Window Replacement in South El Monte
Windows come in various styles, shapes and purposes, so costs and services will vary tremendously depending on your project. Below, we go over the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Although the national average of installing one window is about $600, it can range anywhere from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
We recommend requesting free quotes from several window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first step of a window installation is to think about whether you should get a full-frame or pocket installation.
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the whole window, including the sill, trim and frame. Pocket installations are on the simpler end and won't carry as large a bill because they entail 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 installation company should be able to help you choose what's best for your needs. In South El Monte, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in South El Monte
The EcoWatch Reviews team is different from most reviewers, as we examine these companies through a sustainability lens. We have decided to evaluate the top window replacement companies in South El Monte mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the South El Monte area so you can find a quality 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 make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, quality of installation, cost, professionalism, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
South El Monte, CA Window Replacement FAQs
What is the average cost to replace windows?
The average cost of replacing a window can range from $450 to $650. There are a variety of factors that influence the price, such as the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, the number of windows, your property's location and local labor costs.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your home, including slider windows, double-hung and single-hung windows, casement windows, transom windows, bay windows, picture windows and awning windows.
When do I need to use a window installation company?
You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a involved process that can be difficult to do on your own, so it's best handled by the professionals.
When is the best time of year to replace 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 ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
