Interior Door Installation

Interior Door Installation Services in St. Louis, MO
Interior doors play an important role in the appearance, privacy, and everyday function of a home. A door that sticks, drags, will not latch, swings poorly, or no longer matches the surrounding interior can make an otherwise finished space feel incomplete.
Home Pros STL LLC provides professional interior door installation and replacement services for homeowners, landlords, property managers, and real estate investors throughout St. Louis, St. Charles County, Jefferson County, and surrounding Missouri communities.
Whether you are replacing one damaged door, updating multiple doors throughout your home, or installing doors as part of a larger renovation, our team can help evaluate the openings and develop an appropriate installation scope.
Interior Door Replacement
Home Pros STL LLC installs and replaces many common types of residential interior doors.
Services may include:
Removal of existing doors
Prehung door installation
Door slab replacement
Hinge installation
Hardware installation
Strike and latch adjustment
Shimming and leveling
Interior trim installation
Minor jamb repair
Door stop installation
Final operational adjustment
The exact installation method depends on the door type, frame condition, opening size, and whether the existing jamb is being reused.
Prehung Interior Door Installation
Prehung doors include the door slab and jamb as one assembled unit and are often used when the existing frame is damaged, out of square, or being replaced during remodeling.
Installation may include:
Removing the existing door and jamb
Inspecting the rough opening
Positioning and shimming the new unit
Securing the jamb
Adjusting the reveal
Installing trim
Installing compatible hardware
Checking swing and latch operation
Additional framing or finish work may be required when the existing opening does not match the new door unit.
Interior Door Slab Replacement
In some situations, the existing jamb can remain and only the door slab needs to be replaced.
Slab installation may require:
Measuring the existing opening
Trimming or fitting the new slab when appropriate
Mortising hinges
Drilling for hardware
Aligning the latch
Adjusting clearances
Reusing or replacing existing hardware
Door slab replacement generally requires more fitting than simply installing a factory-prehung unit because the new door must work with the existing frame and hinge locations.
Bedroom, Bathroom and Passage Doors
Home Pros STL LLC can install interior doors for many areas of the home, including:
Bedrooms
Bathrooms
Hallways
Home offices
Laundry rooms
Closets
Basements
Utility rooms
Living areas
Hardware can be selected based on the intended use of the room, such as passage, privacy, or non-locking closet applications.
Closet, Bifold and Specialty Doors
Interior door services may also include compatible specialty systems such as:
Bifold closet doors
Sliding closet doors
Barn doors
Double doors
French-style interior doors
Other approved residential door systems
Specialty doors may require additional framing, blocking, track installation, wall clearance, or hardware depending on the system selected.
Interior Door Adjustment and Repair
Not every door problem requires full replacement.
Depending on the condition, Home Pros STL LLC may be able to correct issues such as:
Sticking doors
Loose hinges
Sagging doors
Doors that drag
Misaligned latches
Damaged strike plates
Minor jamb damage
Loose hardware
Improper door swing
If the frame is significantly damaged, out of square, or affected by structural movement, a larger repair or replacement scope may be more appropriate.

Interior Door Installation Costs in St. Louis
Interior door installation costs depend on the number of doors, door style, slab versus prehung installation, existing frame condition, hardware, trim requirements, and whether additional carpentry or fitting is needed.
