"Jay is a really great guy. Very personable and professional. He got back to me promptly and Arrived right on time and did a great job servicing my two garage doors with all new hardware including rollers, springs and pulleys. His price was excellent and more reasonable than the 5 other estimates I received from other garage door companies which is why I went with Jay. Plus he lives near to me and I prefer work with people that are local. I would recommend him to anyone who is looking for service or installation of a garage door."

"Install went great. We love our new door. The installers took the time to do it right. They removed the original door without making a big mess or just "banging it out" it was removed smartly to not damage anything that was supposed to remain. They then assessed what they had to work with and built up where needed to make the install of the new door as secure as possible. The new door went in smoothly and looks fantastic. Al throughout the install they would answer any question I had or my children had. They also took care to make sure the alarm wires and doorbell cam were protected from harm during the install and that they worked as expected when done. Although they were pricier than the average I am convinced our new door will outlast us in this home. I would recommend them and will use them again."

"The installation was efficient and satisfactory; however, I would have appreciated it if the sales rep, when meeting with me at my home and going over the options, would have pointed out that the color of the window frame would not match the color of surrounding wood."

"Jim and his team were knowledgable, professional and very thorough in their work.  We are very pleased with the results.  Jim is creative and finds a way to get things done when faced with challenges.  We had a 2nd story window which was difficult to reach due to landscape and Jim handled it smoothly and with no problem.  His team was conscientious and took their time to make sure each opening was done properly to insure a weatherproof installation.  We highly recommend Trust Builders LLC and are making arrangements to use them again on a basement remodel."

FAQs for doors (interior) installation and replacement projects in Somerset, 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.
