"Anthony Nastasi of NB Woodworks, LLc, has our highest recommendation. He has worked with us over the past year on a variety of projects aimed at refurbishing and improving our home. This has included exterior trim replacement, replacing a box window with a French door and side light unit, and replacing a large unusually sized window. He also built a beautiful mahogony deck. Indoors, he installed a french door which included fine trim work. In addition, he hired excellent subcontractors to powerwash and paint our home and build a patio, porch and walks. We highly recommend Anthony's carpentry skill, as well as his problem solving, planning and coordination skills. He is also a dependable, honest person of fine character."

"We have hired Doctor Fix-It LLC on three occasions so far. The first time we needed shelving installed in our laundry room and a large framed picture hung on a wall. Keith provide an estimate that was very reasonable and competitive. I especially loved his communication! He sent an email with his arrival time and he arrived on time. Keith was very personable and professional. He listened as I explained my requests in detail. The shelving was purchased and installed exactly how and where I wanted as well as the art work. He was very thorough and cleaned the area when he was finished. Recently, we contacted Doctor Fix-It LLC again to remove, paint, and reinstall all the shutters on our home. Keith again was very communicative as this project was dependent on weather conditions, and needed to be rescheduled several times. As this project was happening during CVID-19, Keith consistently remained masked and kept 6 feet away whenever we were together. Again, he was very professional and knowledgeable, noting the old, faulty caulking around the windows when he removed the shutters. We hired him on the spot to re-caulk the windows! This project had many steps and Keith provided updates to us as work progressed. The shutters have been reinstalled and we couldn't be happier with the final product. Our house looks amazing! Additionally, we also needed sliding glass doors to be installed on our bathtub. Keith knew exactly what to order and came fully prepared. I highly recommend Doctor Fix-It LLC for any project, small or large. Keith is now our "go-to guy"!"

FAQs for doors (interior) installation and replacement projects in Millstone-township, 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.
