Interior Door Installation & Replacement in Flower Mound, TX
A new door should fit the opening, not fight it.


Interior Door Replacement for Existing Openings
If the frame and jambs are in good condition, the best solution is often to replace the door itself.
This is called a slab door replacement.
The replacement door must fit the existing opening carefully, including hinge locations, overall dimensions, floor clearance, latch position, and hardware preparation.
Existing homes aren’t always perfectly square, and replacement doors aren’t automatically a perfect fit. It’s the proper fit that makes a new door a finished installation.
Door2Wall can figure out the current opening and decide whether to use a slab replacement or another installation method.
New Interior Door Installation
Some projects require more than replacing the existing slab.
Door2Wall installs residential interior doors for appropriate openings, including select prehung-door installations where the existing jamb or frame also needs replacement.
Common projects include:
- Bedroom doors

- Damaged interior door replacement
- Door upgrades during remodeling or flooring projects
- Replacement of dated interior doors

Slab Door vs. Prehung Door: What's the Difference?
Slab Door
A slab is the door itself without a new frame.
When the existing jamb is in good condition, a new slab can often be fitted into the existing opening. The hinges and hardware must be positioned correctly, and the door may require careful fitting to achieve consistent gaps and proper operation.
A slab replacement can be an excellent choice when the frame doesn’t need to be replaced.
Prehung Door
A prehung door comes already mounted in a new jamb.
This approach may make more sense when the existing jamb is damaged, poorly installed, or otherwise needs replacement along with the door.
Prehung installation involves removing the existing door and jamb, fitting and securing the new assembly, setting the reveals and alignment, and preparing the finished opening for trim as required by the project.
The right option depends on the condition of what is already there, not which door is cheaper at the store.
Proper Door Fit Matters
Even a brand-new door can perform poorly when it isn’t fitted correctly.
A finished installation should account for:
Consistent Clearance
The door needs appropriate clearance around the jamb and above the finished floor without excessive gaps.
Hinge Alignment
Properly positioned and secured hinges help the door swing smoothly and prevent premature sagging or binding.
Clean Latching
The latch should meet the strike correctly without requiring you to lift, push, slam, or pull the door into position.
Flooring Clearance
Carpet, tile, wood, and other flooring can affect the height available beneath the door. Clearance should be considered before the final fit.
Smooth Operation
The finished door should open, close, and latch cleanly without rubbing the jamb or dragging across the floor.
These details are what make an installed door feel like it belongs in the opening.
Replacing Several Interior Doors?
Multiple-door projects can be a particularly efficient way to update a home.
If you’re replacing several doors, Door2Wall can evaluate the project together and provide a flat-rate quote for the complete scope rather than treating each door as an unrelated service call.
This is also a good opportunity to address other door issues throughout the home.
If nearby doors stick, rub, rattle, or don’t latch correctly, include them with your quote request. Door repairs and adjustments may be able to be bundled into the same project.
Updating the Hardware Too?
A new interior door doesn’t have to inherit old or mismatched hardware.
Door2Wall can install compatible knobs, levers, hinges, and related door hardware as part of the project.
For homeowners updating multiple rooms, Whole-Home Door Hardware Upgrades provide a way to replace dated or mismatched hardware with a more consistent look throughout the home.

Repair or Replace Your Interior Door?
Not every problem door needs replacement.
If the door itself is still in good condition but sticks, rubs, drags, sags, or won’t latch properly, adjustment may solve the problem without purchasing a new door.
Door2Wall takes a repair-first approach when repair is the best option.
For existing doors with operational problems, see Door Repair & Realignment.
Replacement becomes more appropriate when the door itself is damaged, you want a different style or material, or the existing door simply isn’t a suitable candidate for repair.
