• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
• Save money on electricity bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in South Brunswick

Let’s take a look at the cost of updating your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Generally, South Brunswick homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at around $600. This is due to the fact that window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

Whether or not you want energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $306 a year on your energy bills in South Brunswick.

How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are usually the most expensive, although 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 more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a 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 increase the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In South Brunswick, the choice will mostly depend on the efficiency of your home and the condition of your existing frames.
