How Installing Energy-Efficient Windows in Altadena Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.
- Decrease your carbon footprint: In Altadena, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Altadena
Windows come in various shapes and sizes, so costs and services will differ tremendously. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. These amounts are based on the specifics of your installation, like the location of your home, size, material, type, number of windows and more.
It’s also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Altadena home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from multiple companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first step when planning an installation is to think about whether you should get a full-frame or pocket installation.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without removing the whole frame, which is usually less expensive than a full-frame installation.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Altadena
EcoWatch is different from most reviewers since we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Altadena area so you can find a quality 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 company featured in our guide to make sure 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 online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, cost, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure 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 to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Altadena’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Altadena window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Altadena, CA Window Replacement FAQs
How much should window installation cost?
The national average cost to install a window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
The most common types of windows for homes are casement windows, bay windows, double-hung and single-hung windows, awning windows, picture windows, slider windows and transom windows.
Do I really have to use a window installation company?
You should hire a window installation company whenever you need to replace your windows. Installing windows is a involved process that can be difficult and time-consuming, so it’s best handled by the professionals.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
