How Installing Energy-Efficient Windows in Palo Alto Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:

• Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Switching to energy-efficient windows can help reduce that amount, which helps you save $562 a year on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Palo Alto

Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you can find from window installation companies.

How Much Do New Windows Cost?

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

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

Something else that influences the overall cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company can advise you on the best type for your project. In Palo Alto, the decision will mostly depend on the efficiency of your home and the age of your existing frames.
