How Installing Energy-Efficient Windows in Hamilton Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

• Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Hamilton

Let’s go over the cost of replacing your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Typically, homeowners in Hamilton can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs will vary considerably depending on the quality of your products, the number of windows you need, the current condition of your home and your location. A lot of window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.

It’s also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Hamilton home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the complete window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot or deterioration. Because these installations are more involved, they will raise the total cost. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you figure out which type of installation you should get.
