How Installing Energy-Efficient Windows in Oakley Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: Since energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $657 annually on your energy bills in Oakley.
Estimated Cost of Window Replacement in Oakley
Each window installation company provides varying services and has varying price points depending on several factors.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. Costs will differ considerably based on your location, the number of windows you need, the current condition of your home and the quality of your products. Many window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.
Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts 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. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can recommend the best type for your project. In Oakley, the decision will mostly depend on how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Oakley
In our search to make your home improvements easier and more eco-friendly in Oakley, EcoWatch examined many companies before settling on these. We have evaluated the best window installation companies in Oakley mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. 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
Because this is a guide for Oakley, we only included companies that serve the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Oakley.
Work Quality
When selecting new windows, the quality and range 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 higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have good things to say about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that have 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 installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Oakley, CA Window Replacement FAQs
How much does window installation cost?
The average cost of installing a window ranges from $450 to $650. There are several factors that affect the price, which include styles and sizes of windows, how energy-efficient the windows are, local labor costs, the materials used in designing the windows, the number of windows and your property's location.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Do you really 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 complex process that can be difficult to do on your own, so it's best left to the professionals.
How long does window installation typically take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
What time of year should I replace my windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
