Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's efficiency can also have a large impact on home energy conservation. If your house has outdated, drafty windows, your HVAC system could be working extra hard to heat or cool your house. This means spending more on electric bills.
Installing energy-efficient windows on your property can help you save money every month on your electricity bills — and you can help the environment, too.
As windows are so important for your home, selecting the best company for you is a big choice to make. That's why the EcoWatch team has made this list of the top window installation companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Moraga 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 ways switching out your windows could benefit you:
- Decrease your carbon footprint: In Moraga, you can lower your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
- Save on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
- 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 your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Moraga
Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you'll find from window installers.
How Much Do New Windows Cost?
According to our research, the typical cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. Costs will vary considerably depending on the number of windows you need, the quality of your products, your location and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.
With windows, efficiency is the most important factor 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 give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Moraga homeowners $657+ each year after replacing single-pane windows.
Asking for free quotes from multiple providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which increase the overall cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window within the frame that's already there. So, instead of taking out the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which kind of installation you should get, you can talk to your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Moraga
In our search to find the most reliable, eco-friendly window installers in Moraga, the EcoWatch team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Moraga, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Moraga.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, quality of installation, quality of parts, cost, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Moraga's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Moraga window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Moraga, CA Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, depending on several factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which type of window is the best?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window replacement companies offer?
Window installation companies cover the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.
Should I replace my windows all at the same time?
If you're upgrading your windows because of energy-efficiency, replacing all the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
