How Installing Energy-Efficient Windows in Lake Ronkonkoma Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Protect your investment: If you have a relatively old home, your windows are most likely outdated.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 house if you decide to sell.
• Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
• Decrease your carbon footprint: By using less energy once you switch to energy-efficient windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• 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.

Estimated Cost of Window Replacement in Lake Ronkonkoma

Each window installer provides varying services and has different prices based on several factors.

How Much Do New Windows Cost?

On average, homeowners in Lake Ronkonkoma can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. This is because of the fact that window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

It’s also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Lake Ronkonkoma home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which increase 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. Pocket installations are on the simpler end and won’t cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

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