How Installing Energy-Efficient Windows in Dartmouth Saves You Money

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

• Save on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
• 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.
• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Dartmouth

Windows come in various shapes, purposes and styles, so costs and services will vary remarkably depending on your project. Below, we detail the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Although the average cost of replacing a single window is about $600, it can range from $200 to $1,200. These figures are based on specific characteristics of your installation, including the location of your home, size, number of windows, material, type and more.

It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Dartmouth homeowners $460+ a year when replacing single-pane windows.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

If you’re not sure which type of window installation service you should get, your installer should be able to advise you. Generally, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.
