When ordering a shorter prehung exterior door, it is typically easiest to order from a lumberyard. However, it is possible to shorten the unit yourself, typically allowing wood doors to be trimmed by 1⁄2 in. at the top and 1-1⁄2 in. at the bottom. To do this, disassemble the unit, remove the door from its frame, place it on a surface that won’t scratch the door, and remove the door-bottom weatherstripping.

Mark the cut on each edge of the door and clamp a shooting board to the door, positioning the clamps with their long ends down to avoid interference with the saw. Place a block under each clamp to protect the other side of the door.

What is the best tool to cut fiberglass with?

The text recommends using a hand-held hacksaw with a fine-tooth blade, a portable bandsaw, a chop saw with a diamond cutting blade, and an abrasive blade cutter for cutting fiberglass. These tools are recommended for their ability to make clean cuts. The chop saw with a diamond cutting blade is more portable and faster than a hand-held hacksaw. Porta-band saws are common for cutting metal conduit, while a hand-held hacksaw with a fine-tooth blade is portable and commonly available. However, the Sawzall Ⓡ is not recommended for cutting fiberglass conduit due to high-speed reciprocation.

How do you cut fiberglass without chipping it?

1. Hold your cutting tool firmly and make the cut along the marked line, using a slow, steady motion. Avoid applying too much pressure to avoid splintering or cracking. If using a saw or rotary tool, use a blade specifically designed for cutting fiberglass to minimize splintering and fraying.

2. Sand the edges with fine-grit sandpaper to smooth out rough or jagged edges. This will prevent splintering and make the fiberglass easier to handle.

3. Wear appropriate personal protective equipment, choose the right cutting tool for the job, and take time to ensure a clean, precise cut.

Can you cut the height of an exterior door?

It is possible to cut the door from the top without removing the weatherstrip, although approximately one and a half inches of it are required.

Can you cut 2 inches off a door?

The trim of a door depends on the material used, with solid wood doors being easier to trim due to their uniformity throughout. Some doors may only have a solid core for an inch around the sides before becoming hollow. It is generally recommended not to trim more than two inches off any door to avoid damaging it. Hollow-core doors have a strong outer frame at the top, bottom, and sides, making them suitable for trimming.

However, it is crucial not to cut too much away, as this could damage the structural integrity and require replacing the outer frame. It is recommended to consult the manufacturer or product finishing instructions to avoid significant damage or the need for a new door.
