Windows are windows, right? Not entirely. Our window specialists will talk you through your options based on your home’s style and your budget. We sell multiple brands of windows, so make sure to find a window that best meets your needs.

Unlike window-only suppliers, Monk’s offers many products and services. We want you to be our customer for as long as you live in northern New Jersey. Therefore, we offer a pleasant, no-pressure showroom environment. Our prices are the same no matter the day or the week you order them. We want you to be happy with your windows and the installation process.

Buying and Installing Replacement Windows

Window replacement is just how it sounds. We pop out the old sashes and replace them with a pocket replacement window built to fit within your existing window frame. Windows are most commonly replaced to improve energy efficiency like upgrading from old single-pane to double-pane glass, for example.

Benefits of Replacement Windows (sometimes referred to as ‘retrofit’)

  • Installation is fairly quick
  • Less expensive – labor and required materials are not as much
  • Still can upgrade the quality and energy efficiency

New Construction Windows

Monk’s can also provide new construction windows for additions or remodels. New construction allows for different sized or placed windows. Improved insulation where needed is another benefit.

Leaky windows and doors account for up to 25 percent of the average household’s energy bills*. Our northern New Jersey climate with extreme winter and summer temperatures is an area where you can really save money on energy costs by installing energy-efficient types.

More information on the window brands options that we sell and install are featured on our website or can be discussed during your free estimate.

The Monk’s Process

The first step is to schedule a free estimate at 973-635-7900. We will come out to your home, take measurements and discuss your needs. A written estimate for the installation cost will be provided on the spot. If it is a straight replacement project and you have an idea of what you want, we can also price out the windows while we are there.

If you are looking for something custom or want to see your different options, you’ll come into our showroom and meet with our window specialists. They will help you decide what product is best to meet your style preferences and budget requirements.

We will provide you with an easy, hassle-free experience, without any high-pressure sales tactics. For a straightforward estimate, please call 973-635-7900.
