How Installing Energy-Efficient Windows in Janesville Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, such as:

• Save on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $483 annually on your energy bills in Janesville.
• Decrease your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Janesville

When considering window installation, each company offers varying services and prices. Let’s look at some average costs and services.

How Much Do New Windows Cost?

On average, homeowners in Janesville can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will make your project cost more.

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Janesville homeowners $483+ per year after replacing single-pane windows.

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are usually 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 shown to be more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the entire 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 are more involved and will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you’re not sure which type of window installation service you need, your installer should be able to help you out. Typically, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.
