How Installing Energy-Efficient Windows in Discovery Bay Saves You Money

When you switch to energy-efficient windows, you may see some benefits, such as:

  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that number, which helps you save $657 a year on your bills.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Discovery Bay, that's about 117 pounds per year on average.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • 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 Discovery Bay

Windows come in different shapes and sizes, so costs and services will differ remarkably. 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 national average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is because of the fact that the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are completely 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?

In regard to window replacements, in general there are two kinds that your installer will offer: full-frame and pocket installations.

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Discovery Bay, the choice will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Discovery Bay

In our search to find the most reliable, eco-friendly window installers in Discovery Bay, the EcoWatch team assessed dozens of companies before deciding on these. We have assessed the top window replacement companies in Discovery Bay primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Discovery Bay, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Discovery Bay.

Work Quality

When choosing 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 of window you choose. 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

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good 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: as with most services, cheap window installation companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Discovery Bay's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Discovery Bay window companies to prepare homes for these issues.
