How Installing Energy-Efficient Windows in Oakley Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, such as:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty.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.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help reduce that number, which helps you save more on your bills.
- Better temperature control in your home: Energy-efficient windows can decrease the amount of heat lost through your windows when heating your home.
Estimated Cost of Window Replacement in Oakley
Let's go over the cost of installing new windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
Though the average of replacing one window is about $600, it can range from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oakley homeowners $579+ per year after replacing single-pane windows.
Getting free quotes from multiple providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.
A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation means replacing a window without taking out the whole frame, which tends to be cheaper than a full-frame installation.
Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Oakley
In our search to find the most reliable, eco-friendly window installers in Oakley, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated 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 a wide variety of states and cities so you can find the best 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 installer on this list to make sure its contractors are well-qualified and that the company has gotten tons 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 nice things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Oakley, CA Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing one window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is typically influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes include: picture windows, awning windows, double-hung and single-hung windows, bay windows, casement windows, transom windows and slider windows.
When should I use a window installation company?
Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
What time of year is the best time to replace my windows?
Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, the weather should be dry, because rain can make the installation more difficult.
