"Loved working with Window King and highly recommend them! I was nervous about replacing my three really old windows in my old Hoboken condo. Nick walked me through the entire process so that I felt comfortable with the windows I was choosing as well as colors, and so that I was in line with what the HOA would/ wouldn't allow. Cesar and his crew were present on install day - they were on time, courteous, fast, professional, and did an incredible job. I don't think it even took them four hours. And big thanks to Lisa who was extremely communicative regarding the timeline. My condo is now far less noisy in terms of the noise coming from the street- and MUCH warmer which is exactly what I needed. Pictured are two of my old and new windows - the black lining are the old ones and white lining is the new. If I have the good fortune to own another home, I will use Nick/Cesar/Window King without a doubt."

"We used to love this service and gave them glowing reviews on Google in the past, but something has changed. Their customer service sucks, they don't apologize, don't call back etc. We had a hot water heater installed 2 years ago. It is still under warranty. Yesterday, 11/9/25, it broke and started leaking badly - still under a warranty from them. A.J. Perri advertises as they are 24/7 company, but they would not come yesterday and would promise us that first thing this morning, at 8 am, they would be knocking on the door. They never came, never called and never apologized. In fact, they have an attitude for misleading us and at 10 am mo one is here. The technician (do they only have 1 technician?) Is over 1 5 h away at another job. Customer service sucks with them really badly and now I feel as because we called them and voiced our dissatisfaction, no one will reach out to us or help us, while we are covered by their warranty. We had to pay for another service last night to pump"

FAQs for doors (interior) installation and replacement projects in Flemington, NJ

If your existing frame is in good shape, you can replace an interior door without changing the frame. This is a budget-friendly option because it saves on the cost of removing and installing a new frame. By choosing a slab door that fits your current frame, you'll save on labor and materials. Just make sure the new door matches the old one's dimensions for a smooth replacement.

Standard interior doors are 80 inches tall and range from 28 to 32 inches wide. Interior doors vary from 24 to 36 inches wide, depending on their purpose and the available space. Building codes require interior doors to be at least 80 inches tall and 24 inches wide. Knowing standard sizes helps you select a new door that fits properly in your existing opening.

It costs $600 to $2,000 or more to move an inside door. The total price depends on your location, the type of door, and materials needed to complete the project. Moving an interior door requires walling up the leftover space and opening up a new wall where you want the door to go instead. You’ll also want to plan for the expense of framing the new wall opening and adding trim.

Exterior door installation costs an average of $1,175, with a typical range of $525 to $1,800. The higher expense compared to the cost of interior doors comes from the need for exterior doors to be weather-proofed and they are often made of thicker, more durable materials. The associated exterior hardware must also be able to withstand harsh weather, so these cost more as well.

It costs between $300 to $2,500 to make a doorway wider on average. However, the wider you need the space to be, the more it will cost. Some homeowners choose to widen interior doorways to make the house more wheelchair accessible. In order to be wheelchair accessible, an interior door needs to be at least 32 to 36 inches wide. Also, some older homes just have narrow doorways due to the nature of how homes were built differently many decades ago.

It takes between two to five hours for a professional door installer to install an interior door, depending on complexity and materials. A pre-hung door typically takes around two hours, and larger doors like double French doors can take up to five hours. If you’re doing the project yourself, expect it to take a little longer than that, especially if you have little to no experience completing this type of project. Keep in mind that a pre-hung door can be installed about an hour or two faster than a slab door.
