How To Resize A Steel Exterior Door By Cutting Its Top?

To resize a metal exterior door, start by removing the door from the frame and preparing a clean, stable surface. The best way to cut the door to fit your space is to work with the bottom first. A table saw with a fine blade can be used to get your outside metal door cut to size.

In this video, carpenter and former senior editor Andy Engel shows how to disassemble a prehung exterior door, measure and cut the door slab to fit an existing opening, and shorten the jamb to match. The step-by-step door resizing process is provided, and careful attention is paid to ensure accuracy and avoid damage to the door.

The type of blade used depends on the steel used for the door. A battery powered 5-1/2″ circular saw (trim saw) with a standard blade is recommended, set just below the thickness of the steel. Remove the head jamb, remove weather stripping, and cut the sides to the size you need. Put the jamb together and weather the door.

A carbide blade or abrasive wheel on a circ saw is a good way to go, or a Sawzall with a guide clamped to the door. Trimming a steel door would weaken the structure and leave an opening for water intrusion. The door should be removed from the frame and weathered before repositioning the hinges to move the door up on the jamb.

How to fix door gap top?

Older doors can sag due to wear and tear, causing the door to fall out of alignment with the frame. To fix this, tighten the hinges and adjust the alignment if necessary. Replace old screws with larger ones to reinforce the hardware. Incorrectly installed weatherstripping can cause gaps in exterior doors, exposing the home to drafts, leaks, and bugs. Install new weatherstripping to keep the outdoors on the right side of the door. Sealing gaps in your front door can be done using various methods.

Can you cut a door to make it fit?

Trimming down interior doors, including hollow core doors, is possible and often necessary to achieve the desired fit. While there is no standard legislation for door size, many brands adhere to a set of common sizes. It is crucial to take precise measurements and purchase a door that is as close to true as possible. Minor adjustments may be necessary due to varying frames, rough openings, and floor coverings. While it is possible to shorten a new door to fit into an old frame, it is important not to cut away too much material.

If your frame is close to standard, it may be easier to buy a pre-finished door and trim the sides, top, and bottom down to fit perfectly. The parts need to be touched up with the same stain or paint color, but the project is relatively easy.

How do you adjust the height of a door?

To adjust the height of a door, remove the cover of the vertical adjusting screws and use an Allen key to adjust the screws. After adjusting the lower hinge, tighten the height-adjusting element until the door’s weight is balanced evenly on both hinges. This manual can be used for any door type, as long as its hinges don’t significantly differ from the contemporary layout. To adjust the front door, access the adjusting screws, which are typically integrated into the hinges in modern building components. Check the data sheet of your specific front door for the location of the screws. Older front doors may not have adjusting screws, making adjustments more complicated and requiring professional help.

How can I make my exterior door fit tighter?

The text proposes a rapid solution for a narrow, closed front door utilizing a screwdriver. It suggests inserting the screwdriver into the tab and prying it out.

How to cut a metal threshold?

The process of cutting a threshold depends on the material used, such as a hacksaw, bandsaw, angle grinder, or jigsaw. It is essential to select a blade suitable for the material being worked on, such as aluminium and brass, which are soft metals that cut more easily than stainless steel. Protect the finish with paper masking tape, a file for minor adjustments, and a workbench clamping device to hold the threshold while cutting.

Drilling the threshold may be necessary if it is not pre-drilled or shortening has removed some pre-drilled holes. To avoid marking the area, use masking tape, split point drills, and a small pilot hole. Use cutting oil to prevent the drill from becoming blunt and burning the surface. Stainless steel will be harder to drill, and cobalt drills may be required with plenty of oil and using pilot holes.

Countersink the holes using a countersink bit designed for metals. Use screws of adequate length to achieve a secure fixing and if possible made from the same material as the threshold to avoid electrolytic corrosion, especially in damp areas.

Finally, fit the threshold by screwing in place with countersunk screws and plugs, gluing in place with sealant, or a combination of the two. If there is a need for frequent removal, screw fixing is best, although some sealant may be required at the external edges to protect from water ingress. Clean loose dirt away before fixing to ensure adhesive sealants have a sound surface to adhere to. Translucent sealants usually look best when fitting thresholds.

Can you cut the top of an exterior door?

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 trim above an exterior door called?

An architrave moulding, also known as a door header, is the top horizontal trim piece over the door, wider and thicker than the casing. It is a classic look and can come as a one-piece mould or built up from multiple trim pieces. A back band is a decorative trim added to the outside edge of the casing to add depth and width. The baseboard ties the wall and floor together, providing a visual foundation and protecting the walls from bumps and cleaning. It should be thinner and wider than the casing and should complement the casing style. Shoe moulds may be used if the floor is uneven or there are gaps between the baseboard and the flooring.

Can you cut an exterior steel door to fit?

The door is made of 0. 022″ steel, which is less than half the thickness of a U. S. dime. To cut the steel, a battery-powered 5-1/2″ circular saw with a standard blade was used. The blade depth was set just below the steel’s thickness to avoid cutting through the bottom rail. To maintain a straight cut, a straightedge was clamped to the door, measuring from the blade edge to the saw’s base. The door was cut through the first side, then flipped and repeated. This method is suitable for cutting off more than 1-1/2″ of steel.

Can you cut a steel door with jigsaw?

Jigsaw blades are essential tools for cutting metal, with a single row of teeth along one edge. A blade with 21-24 tpi is recommended for durability, and one with a bi-metal construction is recommended. Proper PPE, including eye and ear protection and good quality gloves, is essential. Mark out or score cut lines, securely clamp the workpiece to the bench, and use a technique called’sandwiching’ between thin sheets of wood to minimize distortion.

With the power supply turned off, insert the appropriate blade into the saw, ensuring it is secure and tightened. Check the settings for metal cutting, ensuring the blade is set in a straight down position and not angled forward on the wood setting. If the metal surface is easily marked, cover the saw shoe with masking tape to protect the surface finish.

Start the cut at the edge by pressing the saw shoe firmly on the workpiece’s surface without the blade touching the metal. Slowly depress the trigger and let the blade glide into the workpiece. If starting the cut away from the edge, drill a hole large enough to insert the blade in and continue.

Once the cut is underway, pause the saw and add a few drops of tapping and cutting fluid to reduce heat at the blade. Move clamps and rotate the work to achieve the best cutting line.
