How Installing Energy-Efficient Windows in Novato Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are a few reasons you may want to consider making the switch:
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save $635 a year on your bills.
- Reduce your carbon footprint: By using less energy after switching to Energy Star certified windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Novato
Let's take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Generally, homeowners in Novato can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. This is due to the fact that window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Novato homeowners $635+ a year when replacing single-pane windows.
Another factor that influences the total cost is the material of the frame you select. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when considering an installation is to decide whether you should get a full-frame or pocket installation.
Full-frame installations entail replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. Because full-frame installations are more involved, they will raise the overall cost. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
If you're unsure which window installation service you should get, your installer should be able to assist you. Generally, 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 Novato
The EcoWatch Reviews team differs from most reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
This one is 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 best window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Novato's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Novato window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Novato, CA Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to install one window is around $600 but can range from $200 to $1,200, based on several factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and have experience with installing a replacement window, you may be able to install your own windows. But if you don't have the time or skills, we don't recommend it.
How long does window installation typically take?
Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, the weather should be dry, as rain can make the installation more difficult.
