How Installing Energy-Efficient Windows in August Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to make the switch:
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Save on power bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in August
When looking into window installation, each company offers varying services and costs. Let's go over some typical costs and services.
How Much Do New Windows Cost?
According to our research, the typical cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will add extra costs to your project.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has significant rot. With this service, your installers will replace the entire window, including the frame, trim and sill. Pocket installations are simpler and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in August
EcoWatch reviews are different from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the August area so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company included on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try 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 substantial investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to August's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of August window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
August, CA Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost to install a window can range from $450 to $650. There are many factors that affect the price, which include styles and sizes of windows, the number of windows, local labor costs, the materials used in designing the windows, your property's location and how energy-efficient the windows are.
What are the most common types of replacement windows?
The most common kinds of windows for homes are slider windows, picture windows, bay windows, awning windows, casement windows, transom windows and double-hung and single-hung windows.
Do you really have to use a window installation company?
You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best left to the professionals.
How long does window installation generally take?
Since the average installation time is 30 minutes per window, about 16 windows can be installed during an 8-hour work day.
How do you know it's time to replace your windows?
Windows typically have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they are in need of a repair or replacement.
