How Installing Energy-Efficient Windows in Alamo Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $657 annually on your energy bills in Alamo.
- Reduce your carbon footprint: In Alamo, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year after you install energy-efficient windows.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Alamo
When considering window installation, each company offers varying services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range from $200 to $1,200. These figures vary based on specific characteristics of your installation, like size, the location of your home, number of windows, material, type and more.
Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $657 a year on your energy bills in Alamo.
The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In regard to window installations, there are generally two types that your installer will have: full-frame and pocket installations.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
Your window installation company will be able to help you understand what's best for your needs. In Alamo, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Alamo
In our search to make your home improvements easier and more eco-friendly in Alamo, the EcoWatch team evaluated many companies before landing on these. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Alamo so you can find the best window installation company near you.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of installation, warranty, quality of parts, cost and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that give you 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 quite some time. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Alamo, CA Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost to replace a window is about $600 but can range from $200 to $1,200, depending 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, keep 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 should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies provide?
Window installation professionals will do the entire process — from replacing old windows with new ones to cleaning up afterward. Additionally, some companies offer window manufacturing, customization and repairs.
How long does it typically take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.
How often do you need to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
