How Installing Energy-Efficient Windows in Maryland Heights Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, including:

• Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Maryland Heights, that’s about 763 pounds per year on average.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Maryland Heights

Each window installer offers varying services and has varying costs depending on several factors.

How Much Do New Windows Cost?

On average, Maryland Heights homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost varies depending on several factors, including size, the location of your home, number of windows, material, type and more.

Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $376 a year on your energy bills in Maryland Heights.

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

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Maryland Heights, the choice will mostly be influenced by how much damage there is currently and the age of your existing frames.
