How Installing Energy-Efficient Windows in Port Washington Saves You Money

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

• Save money on power bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 497 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.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Port Washington

When considering window installation, each company provides varying services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Port Washington can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But costs will differ considerably based on the quality of your products, the current condition of your home, the number of windows you need and your location. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $433 a year on your energy bills in Port Washington.

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

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies provide: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window within the frame that’s already there. This means instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which window installation service you should get, your installer can advise you. In general, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.
