How Installing Energy-Efficient Windows in Alameda Saves You Money
When you switch to energy-efficient windows, you may see some benefits, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas 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- Protect your investment: If your home is on the older side, your windows are most likely outdated.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 raise the value of your home if you decide to sell.
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Installing energy-efficient windows can help reduce that number, which helps you save $531 a year on your bills.
Estimated Cost of Window Replacement in Alameda
Each window installation company offers varying services and has varying price points depending on several factors.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is because window installations depend on several 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 want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $531 a year on your energy bills in Alameda.
Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. 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 using 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 offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning a replacement is to clarify whether you need a full-frame or pocket installation.
A full-frame installation is a replacement of the total window. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re unsure which type of window installation service you need, your installer should be able to advise you. Typically, the decision is influenced by 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 Alameda
EcoWatch is different from most reviewers because we’re examining these companies through a sustainability lens. We’ve assessed the top window installers in Alameda primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We’re willing to bet that you’re looking for a company to do a great 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
Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their service from a certain company, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, 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. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

How much should a window install cost?
The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
A window’s energy efficiency is affected by a number of factors, such as 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.
What do window installers do?
Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.
How often should you replace your windows?
Windows generally last around 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
