Are there pictures of a fire cut?

A fire cut is also called a fireman's cut. It is a diagonal cut that is made at the top of a joist used with a brick or stone wall. The fire cut acts as a safety feature to cut the risk of the wall falling if there is a fire. Pictures of fire cuts would be found in blue prints and engineering designs for buildings.


How do you repair deck joists on a cantilever deck?

Not knowing if the joist are in need of repair from rot (deterioration) or broken/damaged then replace ment of joist may be necessary. First get a replacement joist of the same or better species and treatment content and dimensions as the existing joist. Then cut the joist to the same length. You may have to cut a small angle on the bottom end of the joist to aid in working it over and between the girts and decking boards. Work the joist within a few inches of the joist to be replaced. Use a short 4x4 to drive the joist or a wood block to strike with a hammer. Take a couple of scrap 2x's and temporarily fasten to the girts and new joist to prevent movement. Then you may try a couple methods to remove the old joist. If the decking is fastened with screws then simply backout the screws. If it is nailed, then a 10 lbs. hammer can often remove most anything you need and is a great stress reliever but I recomend you use a reciprocating saw to cut the fasteners between the joist and decking. Usually the vibration of the saw and nails being cut will loosen the deck side of the fasteners and allow you to go top side and pull the old nail halves out. Once the old joist and fasteners are out you can carefully work the new joist in place. I recommend fastening the old decking to the new joist with properly coated screws or a hotdipped galvanized rink shank nail. Repeat joist replacement as necessary on other joist.

How do you repair a sagging ceiling joist?

There are several ways, but probably the easiest way would be to temporarily buck under the afflicted ceiling joist with a 2x6 temporarily, until the joist is in line with the others. Then go into the attic and cut and attach a 2x6 to the joist and vertically to the roof ridge. Remove the buck. The joist should stay in place.
