How Installing Energy-Efficient Windows in Hempstead Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, such as:

• Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

What Services do Window Installers Offer?

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

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installation company will be able to help you decide what’s best for your needs. In Hempstead, the decision will mostly be based on the age of your home and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional examine your frames and window sills.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for.
