Door Sweep, Mortised

Mortised Door Sweeps and Recessed Door Bottom Seals

Mortised door sweeps are installed into a prepared channel or notch in the underside of the door, keeping the door bottom seal recessed and less visible from the exterior. This concealed installation makes mortised door bottoms a popular choice for architectural, custom and design-focused door applications.

TM Hardware offers mortised door bottom sweeps for commercial and residential doors, with options for wood and metal doors and different seal configurations including rubber, neoprene and brush. Browse mortised door bottoms from trusted manufacturers including Pemko, Barzen, Zero and NGP.

Concealed Door Sweeps for Wood and Metal Doors

Mortised door bottoms can be used with both wood and metal doors when the door construction allows a recessed installation. Because the sweep is installed into the underside of the door, much of the hardware remains concealed when the door is closed.

This makes concealed door sweeps suitable for custom doors, architectural entrances, luxury residential projects, commercial buildings and other applications where the appearance of surface-mounted hardware is a concern.

Mortised Rubber and Brush Door Sweeps

Mortised door sweeps are available with different seal materials depending on the application. Rubber and neoprene door bottom seals provide a continuous sealing surface and can help reduce drafts, air, dust, light and moisture beneath the door.

Brush door bottom sweeps use flexible filaments that can accommodate some uneven floor or threshold conditions. The right seal type depends on the door, floor condition and required level of bottom sealing.

For surface-mounted brush options, see our Brush Door Sweeps category.

Mortised Door Sweeps for Commercial and Residential Applications

Mortised door bottom sweeps are used on residential doors, commercial doors, architectural entrances and custom-designed doors. They are particularly useful where a recessed installation is preferred over an exposed surface-mounted sweep.

For commercial applications, consider the door construction, bottom clearance, threshold and required seal configuration. For custom residential and architectural doors, installation depth and the finished appearance of the door bottom are also important considerations.

Benefits of a Mortised Door Bottom

A mortised door bottom provides several practical advantages for suitable door applications:

• Recessed installation keeps the sweep less visible.
• Provides a cleaner appearance along the bottom of the door.
• Available with rubber, neoprene and brush sealing options.
• Suitable for many wood and metal door applications.
• Helps reduce drafts, dust, light, insects and moisture beneath the door.
• Available for commercial, residential and architectural door projects.

Mortised vs. Surface-Mounted Door Sweeps

A mortised door sweep is recessed into the underside of the door, while a surface-mounted door sweep attaches directly to the visible bottom face of the door. Mortised designs are often selected when a less visible installation is desired.

Mortised installation requires the appropriate channel or notch in the door and may require removing the door during installation. Surface-mounted sweeps generally do not require the same recessed preparation.
