Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. During the summer months, the last thing you want is your cool air to leak out of your outdated windows.
That's also bad news for the environment, as the extra energy used by damaged windows increases your carbon footprint.
Efficient windows are particularly important in Rohnert Park, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $418 a year.

How Installing Energy-Efficient Windows in Rohnert Park Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Save on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- 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 because of their ability to filter out damaging UV rays.
- Better temperature control in your home: When you reside in a city like Rohnert Park where the summers can be quite hot, you usually need to depend on your air conditioner to keep your house cool. Energy-efficient windows can reduce how hard your AC needs to work to cool your home.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Rohnert Park
Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and the primary services that you'll find from window installation companies.
How Much Do New Windows Cost?
Although the average of installing one window is about $600, it can range from $200 to $1,200. This is because the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Rohnert Park homeowners $418+ a year after replacing single-pane windows.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames have the lowest price. 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 from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most 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 typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are on the simpler end and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
If you're not sure which window installation service you should get, your installer can advise you. Typically, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Rohnert Park
The EcoWatch Reviews team differs from most reviewers because we look at these companies through a sustainability lens. We have reviewed the top window replacement companies in Rohnert Park primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Rohnert Park, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Rohnert Park.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive feedback about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Rohnert Park's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Rohnert Park window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Rohnert Park, CA Window Replacement FAQs
What is the average cost to install windows?
The national average cost to install a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
A window's energy efficiency depends on a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.
How often should you replace your windows?
Windows generally have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them looked at by an expert to determine if they need any repairs or replacements.
