Hi, I'm Dave Osborne. With over 50 years experience as a journeyman carpenter, foreman and contractor in heavy construction I enjoyed working with apprentices and sharing the tricks of the trade that others shared with me. Now I get emails from Members all over the world and we include many of my answers in our Free Monthly Newsletters. Some of my answers include drawings and instructions specific to a project, but may also answer your questions. I use correct construction terminology, so you can confidently inform your building supply dealers or contractors exactly what you need.

Tip of the Month

When pulling finish nails out of a piece of molding, pull them all the way through from the back using a pair of pliers to avoid scratching or splintering the face of the wood.

And a Bonus Tip:

If you are cutting on saw horses, it is a good idea to set the depth of the blade just below the surface you are cutting to avoid too much damage to the saw horses. It is also easier on the saw.

During the last few years answering questions on this website, I've retained a few good examples of different types of deck stairs.

Basic Deck Stairs

deck stairsHere is an example of the basic deck stairs off a raised backyard wood deck. Notice that the one piece 4x4 posts holding the deck stairs railing also carry the weight of the stair stringers. When attaching stair stringers to a backyard wood deck with only a 2x6 box joist, there usually is nothing to attach the stair stringers to. Here the stair stringer is bolted to the posts and a ledger board is installed under the stair stringer for those with a longer run. Either pressure treated wood or concrete pads are shown under the posts and bottom stair of the stair stringer, rather than having the stair stringers and posts just sitting on the ground.

Special Deck Stairs

tapered deck stairsIn this drawing, tapered deck stairs are shown with the stair treads having equal depths as they turn the corner. This example shows a run of deck stairs between two levels of a backyard wood deck.

extended deck stairsNotice in this drawing that the deck stair treads are extended in depth so that the stair nosings are all the same lengths.

deck stairs returnIn this drawing is a raised backyard wood deck of about 5' with deck stairs returning back to the deck. A set of deck stairs such as this is a bit more complicated than the simple deck stairs in the first drawing. This example is from a custom plan that I drew up for Tom, a member of our site. Refer to my article Deck Stairs with Returns. for the plans for these deck stairs.

Other ideas for deck stairs may be to climb up to a pool or hot tub.

pool deck stairs

pool deck stairs againRather than climbing up to a pool, here is a sketch of a pool or hot tub enclosed by a deck, but not sitting on it. The pool or tub is sitting on a level bed of compacted sand.

deck stairs on slope

Here is a drawing I did for a couple who had to contend with the back garden sloping 90 degrees to the direction of the deck stairs. Notice how we divide up the vertical height difference as well as the width of the deck stairs for the supports, so that each support has a different height. Since the height difference is 4" we can still stay in the safe envelope of riser height by starting with a height on the left of about 4" and ending with a height on the right of 8".

I hope some of these drawings will help you in deciding how to build your deck stairs and your backyard wood decks.

Remodeling 17: How to Install a Prehung Door

Outside Prehung Door

First once you have the prehung door unit, verify that the size of the rough opening is correct. With a threshold, the height should be 84" for an 80" door. Without a threshold it is 82 1/2". The width for a rough opening should be 2" larger than the prehung door. Example, for a 36" prehung door the rough opening width should be 38". Some prehung doors come complete with brick molding on the outside, which goes against the sheeting. The width of the jamb should match the width of the studs plus the thickness of the inside finish and the outside sheeting.

Apply tar paper to the perimeter of the door opening, so a good overlap of 4" can be done when the wall is papered. Install the prehung door unit into the opening, snug the brick mold into the sheeting, with the prehung door unit resting on the subfloor. With shims or wood shingles split about 1 1/2" wide, shim the sides at the top so the prehung door unit is centered in the opening, as shown:

install prehung door

These top shims are temporary just to position the prehung door and hold it in place. Notice the margin around the prehung door should be the same. Plumb the hinge side of the prehung door first. Shim up the low side of the jamb if the top margin above the jamb is not the same or tapered. Check the plumb on the hinge side, with the prehung door closed and shim opposite the hinges. Screw a 3" x #8 flathead wood screw in through the stop of the jamb through the shims and into the cripple, countersinking them a bit below the surface to be filled later. Do the same at the other hinges, maintaining an equal margin. Now shim and screw the latch side of the jamb into the cripple, keeping the margin the same. Three screws on each side is sufficient, none is required on the top unless the unit is a prehung double door. Shimming the jamb with the prehung door in place makes it easy.

Remove any excess shim sticking out past the jamb with a sharp utility knife or hand saw. Install the lock set as per instructions in the prehung door package.

Inside Prehung Door

Verify the correct rough opening for your prehung door. The width and length should be 2" more than the size of the prehung door. Add 3/4" to the height if hardwood or carpet is being installed below the prehung door.

Follow the same procedure as for an outside prehung door, except for the brick mold and tar paper. The width of jamb should be the width of stud plus the two finishes on the walls.

Hope this helps
