How Installing Energy-Efficient Windows in Piedmont Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Save on electricity bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save about $531 annually on your energy bills in Piedmont.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in Piedmont
Windows come in varying purposes, styles and shapes, so costs and services will vary considerably depending on your project. Below, we detail the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
Typically, homeowners in Piedmont can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is due to the fact that the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $531 a year on your energy bills in Piedmont.
Getting free quotes from several providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. Because full-frame installations are more involved, they will increase the overall cost. A pocket installation means replacing a window without removing the complete frame, which is usually cheaper than a full-frame installation.
Your window installer should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Piedmont
In our search to make your home improvements easier and more eco-friendly in Piedmont, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
Service Area
Because this is a guide for Piedmont, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Piedmont.
Work Quality
When it comes to 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 choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have positive things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Piedmont's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Piedmont window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Piedmont, CA Window Replacement FAQs
What is the typical cost to replace windows in a home?
The typical cost of replacing a window ranges from $450 to $650. There are a variety of factors that influence the price, which include your property's location, local labor costs, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows and the number of windows.
What are the types of windows?
The most common types of windows for homes are slider windows, double-hung and single-hung windows, casement windows, awning windows, bay windows, picture windows and transom windows.
Can I install my own windows?
Although you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company 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.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, it shouldn't be raining, since rain can make the installation harder.
