How Installing Energy-Efficient Windows in Agoura Hills Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could benefit you:

  • 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 your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your property 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 household energy use. Upgrading to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Agoura Hills

Each window installation company provides various services and has varying price points depending on several factors.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range from $200 to $1,200. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will make your project cost more.

It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Agoura Hills homeowners $509+ a year when replacing single-pane windows.

Getting free quotes from multiple providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

In general, there are two types of window installation services you can get: full-frame and pocket installations.

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 a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

If you’re unsure which type of window installation service you should get, your installer can help you out. Generally, the choice depends on 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 Agoura Hills

In our search to make your home improvements easier and more eco-friendly in Agoura Hills, EcoWatch evaluated dozens of companies before deciding on these. We have assessed the best window replacement companies in Agoura Hills mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. 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

This one is 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 certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company included on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Agoura Hills’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Agoura Hills window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Agoura Hills, CA Window Replacement FAQs

What is the typical cost to install windows?

The average cost of replacing a single window can range between $450 and $650. There are many factors that influence the cost, which include local labor costs, the materials used in designing the windows, your property’s location, styles and sizes of windows, the number of windows and how energy-efficient the windows are.

Which kind of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

Although you can 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 installation is done properly and that you won’t have to spend the time and effort to do it yourself.

How do you know it’s time to replace your windows?

Windows generally last around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
