How Installing Energy-Efficient Windows in Mill Valley Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:

• 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.
• Decrease your carbon footprint: By using less energy once you switch to energy-efficient windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
• Better temperature control in your home: When you live in a place like Mill Valley where the winters can be very cold, you often need to rely on your heater to keep your house warm. Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.

Estimated Cost of Window Replacement in Mill Valley

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

How Much Do New Windows Cost?

Though the typical to replace a single window is around $600, it can range from $200 to $1,200. Costs will differ significantly depending on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.

It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Mill Valley homeowners $451+ a year when replacing single-pane windows.

We recommend requesting free quotes from multiple window installers to find the one that works best for your budget.

What Services do Window Installers Offer?

There are typically two kinds of window installation services: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Mill Valley, the decision will mostly depend on the efficiency of your home and how old your existing frames are.
