How Installing Energy-Efficient Windows in Berkeley Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could benefit you:

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Berkeley, that's about 449 pounds per year on average.

Estimated Cost of Window Replacement in Berkeley

Let's take a look at the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Generally, Berkeley homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at around $600. How much it will cost you varies based on several factors, such as size, number of windows, type, material, the location of your home and more.

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

Another factor that affects the overall cost is the material of the frame you select. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want a new style or your window has significant deterioration. With this service, your professionals will replace the total window, including the sill, trim and frame. A pocket installation entails installing a new window within the old frame. This means instead of taking out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you choose what's best for your needs. In Berkeley, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Berkeley

In our search to make your home improvements easier and more eco-friendly in Berkeley, the EcoWatch team examined dozens of companies before settling on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Berkeley so you can find a quality 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 installer included on this list to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good feedback about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure 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 to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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