Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a large impact on home energy conservation. Drafty or leaky windows can cut your home’s energy efficiency by up to 30%, according to the Department of Energy. In Modesto, that’s almost $594 per year that you could save on your energy bills after making the switch.
That’s also bad news for the environment, as the extra energy used by outdated windows increases your carbon footprint.
We’ve made this list of the top installation companies to help you in your search, so you can not only enjoy brand-new windows, but also save money on your electricity bills.

How Installing Energy-Efficient Windows in Modesto Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could benefit you:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Modesto
Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
According to our research, the national average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But costs will differ considerably depending on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase your overall project costs.
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 you replace single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Asking for free quotes from multiple companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two types that your installer will have: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Modesto, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Modesto
In our search to find the most reliable, eco-friendly window installers in Modesto, the EcoWatch team evaluated many companies before landing on these. Along with energy efficiency, we assessed several window installers in Modesto and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Modesto, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Modesto.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you opt for. 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
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good 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 points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Modesto’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Modesto window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Modesto, CA Window Replacement FAQs
What is the typical cost to install new windows in a home?
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 styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs, the number of windows and your property’s location.
What are the different kinds of windows?
The most common kinds of windows for homes are awning windows, double-hung and single-hung windows, transom windows, casement windows, slider windows, bay windows and picture windows.
Do you really need to use a window installation company?
Unless you’re handy and have all the necessary tools to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows together is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
