Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although renewable energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. During the hot summer months, the last thing you want is your cool air to leak out of your outdated, drafty windows.

That's also bad news for the environment because the extra energy used by damaged windows increases your carbon footprint.

Efficient windows are of particular importance in Simi Valley, where summers are long and hot. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $572 a year.

How Installing Energy-Efficient Windows in Simi Valley Saves You Money

When you switch to energy-efficient windows, you may see some benefits, such as:

  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Simi Valley

Windows come in varying purposes, styles and shapes, so costs and services will vary greatly depending on several factors. Below, we describe the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Although the average to replace a single window is around $600, it can range from $200 to $1,200. These estimates vary based on the specifics of your installation, such as material, the location of your home, type, size, number of windows and more.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Simi Valley homeowners $572+ per year after replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations require replacing the entire 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 deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the 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 still trying to decide which type of installation to get, you can ask your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Simi Valley

In our search to find the most reliable, eco-friendly window installers in Simi Valley, the EcoWatch team chose the above companies as the best window installation companies in the city. We've decided to assess the top window installation companies in Simi Valley mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Simi Valley so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice things to say about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Simi Valley, CA Window Replacement FAQs

How much does window installation cost?

The average cost to install a single window ranges between $450 and $650. There are a variety of factors that affect the cost, such as local labor costs, how energy-efficient the windows are, the materials used in designing the windows, your property's location, the number of windows and styles and sizes of windows.

Which type of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not 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 — that means they're certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

While you can install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

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

Windows usually last 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to determine if they are in need of a repair or replacement.

Should I replace all my windows at once?

If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
