How Installing Energy-Efficient Windows in Rossmoor Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to consider making the switch:

• Decrease your carbon footprint: In Rossmoor, you can lower your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save some money on your bills.
• 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 fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Rossmoor

When researching window installation, each company offers different services and prices. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Rossmoor can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at around $600. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will add extra costs to your project.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Rossmoor homeowners $388+ each year after replacing single-pane windows.

The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, but 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 more efficient.

What Services do Window Installers Offer?

The first step of a window replacement is to decide whether you need a full-frame or pocket installation.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you choose which type of installation you need.
