Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's efficiency can also have a big impact on home energy conservation.

Replacement windows improve your home's insulation, not only making you more comfortable during extreme temperatures, but also saving you some money and helping the environment.

How Installing Energy-Efficient Windows in Moraga Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, including:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Moraga, that's about 117 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Moraga
Windows come in different styles, shapes and purposes, so costs and services will differ remarkably based on your project. Below, we detail the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Although the typical of installing a single window is around $600, it can range from $200 to $1,200. How much it will cost is based on several factors, such as size, number of windows, material, type, the location of your home and more.
It's also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that switching out the windows on your Moraga home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. 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.
If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Moraga, the decision will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Moraga
The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. We've decided to evaluate the top window installers in Moraga mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Moraga, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Moraga.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. 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
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including warranty, professionalism, cost, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Moraga, CA Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically dependent on 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 types of windows?
There are several different types of windows you can get for your home, including picture windows, double-hung and single-hung windows, bay windows, awning windows, casement windows, slider windows and transom windows.
Can I replace my own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it generally take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
