How Installing Energy-Efficient Windows in Millbrae Saves You Money

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

• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if your home is on the older side.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save on electricity bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $440 annually on your energy bills in Millbrae.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.

Estimated Cost of Window Replacement in Millbrae

Windows come in various purposes, styles and shapes, so costs and services will differ greatly depending on several factors. Below, we detail the typical cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

On average, homeowners in Millbrae can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. How much it will cost is based on several factors, such as size, material, type, 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 per year when you replace single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are 100% 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?

The first thing to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the total window, including the sill, trim and frame. Pocket installations are simpler and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

Your window replacement company will be able to help you choose what’s best for your needs. In Millbrae, the decision will mostly depend on the age of your home and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional check on your frames and window sills.
