Measuring for Stairtek Stair Parts


When measuring for Stairtek treads and risers you must first understand what Stairtek products are designed to accomplish. With the proper installation the end result of Stairtek’s system is a beautiful, seamless and valuable wooden staircase.

          Stairtek parts are solid wood and can be used in new construction applications, but for The Home Depot customer we will almost always be covering or re-facing an existing staircase.

          Stairtek treads and risers are meant to be glued over top of the existing treads and risers and therefore create a few scenarios that must be given attention.

The primary measuring of the treads and risers is pretty straight forward, treads are available in a few lengths (36”, 42”, 48” etc.) and two widths (10 ½” or 11 ½”). All treads are 1” thick. Also available are mitered and starter treads, again in different dimensions and widths. Risers are available in the same lengths as the treads and are 7 ¾” tall and ¾” thick.


·       When measuring for a double mitered or a double starter tread this measurement must be precise to 1/8th of an inch.


·       An important note: when measuring for a tread, keep in mind not all treads in a staircase are necessarily the same size. It’s a good idea to take the time and measure each tread. Especially if the size is close to the limits of a Stairtek tread. For example: you may have one tread that measures 35 7/8” which would accept a new 36” tread. Then you may have a tread in the same staircase that measures 36 ¼” in which case you would have to order a 42” tread.


Other scenarios to watch for:


·        If there are mitered (open end) treads or starter treads involved then the issue of the railing system must be addressed. Some policies do not allow the installer for Home Depot to manipulate railing systems. We will install the mitered treads but it is the homeowner’s responsibility to remove the railing system prior to the treads being installed. It is also the homeowner’s responsibility to have the railing system replaced. What is needed from the measurer is whether or not the rail system impedes the installation of the treads and risers.


·        When installing mitered treads there will have to be a molding added to the outside of the stair to cover the edges of the old treads that have been covered. A door stop molding is an inexpensive and a good option.


·       In some instances you will find that the toe plate of the railing system hangs over the stringers on a set of box steps. This too needs to be noted because the box treads will not always be able to be dropped into place. There may be some extra labor involved and the customer will have to know this up front.


·        The height of the first riser is important information to gather. Keeping in mind that adding Stairtek stair treads adds an inch to the height of the first rise. If the customer is installing a new ¾” floor this isn’t a problem, otherwise there are limits to how tall that first riser can be and how it relates to the other rises in the staircase. The maximum riser height shall be 7 3⁄4 inches(196 mm). The riser shall be measured vertically between leading edges of the adjacent treads. The greatest riser height within any flight of stairs shall not exceed the smallest by more than 3⁄8 inch (9.5mm).
