Question: How To Install Stair Stringer Hangers

How do you secure a stair stringer?

What kind of hangers do I use for stair stringers?

To attach stair stringers to a deck, you must use a metal stair stringer hanger. End-nailing, toe-nailing, or screwing stringers to a header is not allowed per the International Residential Code. Metal hangers must use appropriately sized nails or fasteners specific to the stringer hanger manufacturer.

Do stair stringers need hangers?

Stringers support the steps of a stairway and fasten to the framing of the deck. The primary method of connection between a stringer and the framing is a stringer hanger. This metal bracket supports the stringer and holds it on the framing. Stringer hangers look like joist hangers and function in the same way.

How do you hang deck stair stringers?

Attach the stringers to the deck using angle brackets and 3” galvanized deck screws. Cut a 2×6 board to fit snugly between the two stringers at their base. This will be used to fasten the stairs to the concrete pad. Place the board between the stringers and attach to stringers with 3” galvanized deck screws.

How do you reinforce stair stringers?

One of the easiest methods of reinforcing your wood stair stringers is using 2×12 skirt boards along the outsides of your stairs. A skirt board is pretty much what it sounds like; triangular shaped wood that goes along the sides of your stair and hides all of the unsightly notched stringers and hardware.

How far apart should stair stringers be?

Deck stairs are typically made from 2 x 12 stringers spaced about 12 to 16 inches apart. They rest on a solid foundation and are attached to the deck with hangers. They have risers (also called toe kicks), treads and railings. The stairs should be at least 36 inches wide.

Can I use 2×12 for stair treads?

It is acceptable and within building code guidelines to use either 2×10 or 2×12 dimensional lumber to create a set of stairs; however, a stair stringer should not be less than 3.5 inches wide at its narrowest point to provide adequate strength for the load the stairs will be supporting.

Can you connect stair stringers?

In some cases, longer runs of stairs call for connecting stringers at an intermediate support to avoid using long stringers that may twist. Other times, you may connect stringers to make the most of the materials you have on hand. Regardless of the application, the method used must ensure a reliable connection.

Can I use screws instead of nails for joist hangers?

Outdoors use 16d double-dipped galvanized nails (or stainless steel when called for) for installing hangers. The manufacturers agree: Never use galvanized deck screws or drywall screws to install joist hangers. Those screws don’t have the shank size and toughness to support joist loads.

Do you use joist hangers on both ends?

Joist hangers are preferable to both toe-nailing and end-nailing. Joist hangers provide greater shear force support to joists, as the hanger allows for both face nailing and toe-nailing into ledger boards and rim joists.

How far does tread overhang riser?

The acceptable tread overhang requirements according to the IRC protrude 3/4″ to 1-1/4” past the face of the riser or riser line to ensure the going is 10-inches. The overhang increases the foot placement space on the tread, but doesn’t change the depth of the going, or tread depth under the IRC definition.

How many stringers do I need for 36 inch deck stairs?

Because of this, you should never space your stair stringers more than 16” on center. This means you will need to install a minimum of four stringers on any stairway wider than 36”. Always check the maximum span for your decking material as it applies to stair treads.

How long can stringers be without support?

The minimum recommended size for a deck stair stringer is 2×12, which has a maximum recommended unsupported span of 6 feet. Often this maximum span is dangerously exceeded, resulting in overspanned stringers that will deflect and cause the connection at the deck to pull loose and fail.

What size lumber is used for stair stringers?

The stair stringers are essentially the backbone of your staircase. Always use straight, high-quality, pressure-treated 2x12s for stair stringers. If you are planning on resting the stringer on the ground, make sure the wood has .

What is the best wood for stair stringers?

LP SolidStart Laminated Strand Lumber (LSL) and LP SolidStart Laminated Veneer Lumber (LVL) are ideal for Stair Stringers because they surpass traditional lumber products in length, strength and consistency.

Why do stair treads crack?

Wood stairs utilize thick stair treads for stability. These hardwood treads can be between 1 1/2 to 2 inches in thickness. When wood is cut this thick, it can split due to humidity changes. Once a stair tread is split or cracked, you can’t glue it back together.

Do you install risers or treads first?

When installing stairs, install the riser first, and then the tread. Start at the bottom of the stairs and work your way up, alternating risers and treads. The back of each tread will sit flush against the riser.

Can I install all risers before treads?

Do work at least one riser ahead before installing treads. Installing two risers is one way to ensure proper strength and performance. The important thing is to remember to install riser, tread, riser, tread or install the risers first.

How do you stop stairs from creaking without removing carpet?

One way you can fix creaking stairs from above is by screwing the front of the tread onto the riser. You can do this by drilling clearance holes for the thick part of the screws (called the shank) through the tread and thinner pilot holes (for the point of the screws) into the top of the riser.

How do you fill the gap between stair tread and riser?

Riser-to-Tread Gap Place the cove molding face up across two sawhorses. Measure the width of the stair tread where it meets the riser. Apply a bead of construction sealant to the back of the molding. Apply colored silicone caulking to stringer gaps. Cut the tip off of a tube of colored silicone with a utility knife.
