• Decrease your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save money on power bills: Because energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save around $283 annually on your energy bills in North Bellmore.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in North Bellmore

Windows come in different shapes, styles and purposes, so costs and services will differ greatly depending on several factors. Below, we detail the typical cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

According to our research, the average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is because of the fact that window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the full window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage or rot. These installations are more involved and will raise the overall cost. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot 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 North Bellmore, the choice will mostly be based on the efficiency of your home and how old your existing frames are.
