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• Protect your investment: If you have an older home, your windows are most likely outdated.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 after you install energy-efficient windows.

What Services do Window Installers Offer?

The first step when planning a window replacement is to decide whether you want a full-frame or pocket installation.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more involved and will increase overall costs. 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 cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Altadena

In our hunt to find the most reliable, eco-friendly window installers in Altadena, the EcoWatch Reviews team examined dozens of companies before deciding on these. We’ve evaluated the top window installation companies in Altadena primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is 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

When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews 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 quality of installation, professionalism, quality of parts, cost, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window companies won’t always provide the highest 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. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Altadena’s climate, homeowners will want to mitigate water damage, low efficiency and rot. 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.
