How Installing Energy-Efficient Windows in Pittsburg Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Pittsburg, that's about 117 pounds per year on average.

Estimated Cost of Window Replacement in Pittsburg

Each window installer offers various services and has different costs depending on a few factors.

How Much Do New Windows Cost?

On average, homeowners in Pittsburg can expect that most window installations will range from $250 to $1,200, with the average cost sitting at about $600. These amounts vary depending on the specifics of your installation, such as size, type, material, number of windows, the location of your home and more.

Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Getting free quotes from multiple companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Pittsburg

EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We have assessed the top window installation companies in Pittsburg mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. 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 installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows don't necessarily 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 scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Pittsburg's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Pittsburg window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Pittsburg, CA Window Replacement FAQs

How much does window installation cost?

The national average cost of installing one window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically influenced by the type and material of the window, the location of your property and the size 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.

What type of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

Do you really have to use a window installation company?

You should use a window installation company whenever you need to replace your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.

What time of year is the best time to replace my windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.

Should I replace all my windows at the same time?

If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
