How Installing Energy-Efficient Windows in Leander Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to make the switch:

• Decrease your carbon footprint: In Leander, you can cut your indirect greenhouse gas emissions by about 507 pounds per year once you switch to energy-efficient windows.
• Save on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you.

What Services do Window Installers Offer?

The first step when considering a window replacement is to decide whether you want a full-frame or pocket installation.

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, 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 Leander, the choice will mostly be based on the efficiency of your home and how old your existing frames are.
