How Installing Energy-Efficient Windows in Oakland Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could benefit you:
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Better temperature control in your home: When you live in a city like Oakland where the winters can get cold, you usually need to rely on your heater to keep your house warm. Energy-efficient windows can cut back on how hard your heater needs to work to heat your home.
Estimated Cost of Window Replacement in Oakland
Each window replacement company provides varying services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
According to our market research, the average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. These amounts are based on specific characteristics of your installation, including size, type, material, number of windows, the location of your home and more.
It's important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Oakland homeowners $435+ a year when replacing single-pane windows.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has significant deterioration. With this service, your installers will replace the complete window, including the sill, trim and frame. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Oakland
In our hunt to find the most reliable, eco-friendly window installers in Oakland, the EcoWatch team examined many companies before landing on these. We've decided to assess the best window installation companies in Oakland mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have nice things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Oakland's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Oakland window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Oakland, ME Window Replacement FAQs
How much should window installation cost?
The average cost of installing a single window ranges from $450 to $650. There are several factors that affect how much it costs, including styles and sizes of windows, the number of windows, your property's location, the materials used in designing the windows, how energy-efficient the windows are and local labor costs.
Which kind of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
You should hire a window installation professional whenever you want to replace your windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best handled by the professionals.
How often do you need to replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
