"I hired Steven to help me replace some interior doors and jams. He is very personable, professional, and did a quality job at a fair price. So based on all that I just had him back to remodel the front of my garage by taking out one 16" door and framing out for two 9" doors. Again, a nice job in a timely manner which was important because the front of my garage had to be open for a few days. Now I am talking to him about a front & rear deck project I am planning out."

"OnCenter Contracting outperformed anyone else we worked with before. They quickly assessed what needed to be done, delivered the quote the next day, made the adjustments we needed on the work. After the contractual phase, they kept us in the loop while they were getting permissions, ordering of the materials, and quickly planned for the work schedule. While they were building our construction (a Pergola on our porch), they were respectful for our time and privacy needs, they were flexible to make the minor changes on the construction we asked for. They even noticed some issues on the existing porch and fixed those problems at material cost only. Overall, we are very pleased with the outcome, and OnCenter Contracting was a very pleasant experience from start to finish."

"Joe from Rebeccaâ s Handyman Services was able to come out the same day I called about removing old, cracking caulk around my garage door. Price was very reasonable and he did a great job, and made sure to clean up the area afterwards. Iâ ll be using him again for other â honey-doâ items in the near future."

FAQs for doors (interior) installation and replacement projects in O Fallon, MO

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.
