How Installing Energy-Efficient Windows in Port St. John Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, including:

• Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
• 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 390 pounds per year on average.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Port St. John

Each window replacement company offers various services and has different costs based on several factors.

How Much Do New Windows Cost?

Typically, homeowners in Port St. John can expect that most window installations will range from $250 to $1,200, with the average cost at around $600. But prices vary considerably based 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 installations, which will make your project cost more.

With windows, efficiency is the most important factor for many 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 decades of energy savings.

Getting free quotes from several providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the complete window, including the frame, trim and sill. Pocket installations are simpler 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 may have to get a full-frame installation instead.

If you’re still debating which type of installation you should get, you can talk to your provider and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage present.
