How Installing Energy-Efficient Windows in Sterling Saves You Money

There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:

• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Sterling, that’s about 419 pounds per year on average.

Estimated Cost of Window Replacement in Sterling

Each window installation company offers various services and has different costs depending on a few factors.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, such as material, the location of your home, number of windows, type, size and more.

It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Sterling homeowners $464+ a year when replacing single-pane windows.

Something else that affects the total cost is the material of the frame you pick. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re not sure which kind of window installation service you should get, your installer should be able to advise you. Typically, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.
