How Installing Energy-Efficient Windows in Mountain View Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to make the switch:
- Save money on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $562 annually on your energy bills in Mountain View.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut 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 harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Mountain View
When considering window installation, each company provides different services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
According to our research, the typical cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will add extra costs to your project.
It's important to bear in mind 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 Mountain View homeowners $562+ a year when replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with 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?
When it comes to window installations, in general there are two types that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the windowsill, 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 are simpler and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
If you're not sure which window installation service you need, your installer should be able to help you out. Typically, the choice depends 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 Mountain View
In our search to make your home improvements easier and more eco-friendly in Mountain View, the EcoWatch team assessed dozens of companies before deciding on these. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Mountain View, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Mountain View.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including cost, professionalism, quality of parts, warranty, quality of installation and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the most quality service. Still, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Mountain View's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Mountain View window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Mountain View, CA Window Replacement FAQs
How much should window installation cost?
The typical cost to install a single window ranges from $450 to $650. There are many factors that influence how much it costs, including the materials used in designing the windows, the number of windows, how energy-efficient the windows are, local labor costs, your property's location and styles and sizes of windows.
Which type of window is the best?
A window's energy efficiency depends on a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
When do I need to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.
How do you know it's time to replace your windows?
Windows generally last 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to see if they need any repairs or replacements.
Should I replace my windows all at once?
If you're upgrading your windows because of energy-efficiency, replacing all the windows together is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
