Piedmont Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Piedmont, CA using our customized window cost calculator.

How Installing Energy-Efficient Windows in Piedmont Saves You Money

There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Reduce your carbon footprint: By using less energy once you switch to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save around $531 annually on your energy bills in Piedmont.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Piedmont

Each window installation company provides varying services and has varying costs based on several factors.

How Much Do New Windows Cost?

Though the national average cost to replace one window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, such as the location of your home, number of windows, material, size, type and more.

Whether or not you want energy-efficient windows is another factor that will determine 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.

The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid 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?

When it comes to window replacements, there are generally two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the whole window, including the trim, sill and frame. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler 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 still trying to decide which kind of installation to get, you can consult with your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Piedmont

The EcoWatch Reviews team differs from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Piedmont area so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher 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 might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, warranty, quality of parts, professionalism, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies may not provide the most quality service. Still, 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. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Piedmont’s climate, homeowners need to be wary of low efficiency, rot 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.
