Why you can trust EcoWatch
Whether you're doing renovations or have old windows, windows play a key role in conserving energy in your home. Outdated windows can cost you in electric bills. In fact, the Department of Energy estimates that 25-30% of your home’s heat or cool air could be lost through your windows.
Replacement windows improve your home’s insulation, not only making you more comfortable during the summer and winter, but also saving you money and helping the environment.
Unlike other sites, EcoWatch ranks window replacement companies on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Hayward Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:
- Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Save money on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Hayward
Each window replacement company offers varying services and has varying costs based on several factors.
How Much Do New Windows Cost?
Typically, Hayward homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at approximately $600. This is because the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $531 a year on your energy bills in Hayward.
Something else that influences the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and light, but they offer 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 as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the full window, including the trim, sill and frame. Pocket installations are simpler and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Hayward
In our hunt to make your home improvements easier and more eco-friendly in Hayward, the EcoWatch team chose the above companies as the top window installation companies in the city. We’ve evaluated the top window installation companies in Hayward primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Hayward, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Hayward.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, cost, professionalism, quality of installation, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum 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 provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Hayward, CA Window Replacement FAQs
What is the average cost to replace windows?
The typical cost to install a single window ranges between $450 and $650. There are many factors that affect the cost, such as how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, your property’s location, local labor costs and the number of windows.
What are the kinds of windows?
There are various types of windows you can get for your home, including transom windows, awning windows, slider windows, picture windows, double-hung and single-hung windows, bay windows and casement windows.
Can you replace your own windows?
While it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window installation company can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.
What time of year is the best time to replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
How long does window installation typically take?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed during a typical 8-hour work day.
