We’ve compiled a
basic list of terms and definitions you need to know to
order stair parts and understand the uses of those parts.
Staircase Types
These are the 7 standard stair types that are
used in most practical applications. We also make custom
design stairs to showcase the unique décor of your
home. Click on CUSTOM to learn
more about our beautiful custom stairs.

Type #1 stair is a complete boxed in
stair with housed stringers on both sides. On this stairway,
the ends of each tread and riser are installed into recessed
stringer routings creating a box appearance.
Type #2 stair has a boxed in section.
In addition, there is an open section with RH or LH returned
end treads one side only the first few steps, usually
no more than six. The exact amount of returned end open
treads is determined by location of the finished wall
line. We ask for this information on line “G”
of our order form.
Type #3 stair is closed or boxed in
one side. The opposite side is open with all returned
end treads. When ordering, indicate RH or LH on line “M”
of the order form.
Type #4 stair is similar to the Type
#2, which is a combination of open end boxed in section
stair, except the open section is open both sides with
mitered RH and LH treads. The exact amount of returned
end open treads is determined by location of the finish
wall line. We ask for this information on line “G”
of the detail sheet.
Type #5 stair is returned end open both
sides, each tread having mitered RH and LH ends. There
is not a boxed in section to this stair.
Type #6 stair is an excellent, heavy
duty, modern appearance stair for open area installations.
This finish stair does not have risers installed and has
a boxed in or open end appearance depending on stringer
location.
Type #7 stair is a boxed in type house
basement stair with no risers installed. Our basement
stair is economically priced and can be stocked for average
ceiling heights.

Understanding Quality
The most important determination of quality is the craftsman. At Colonial Stair & Woodwork, LLC we have a skilled staff, many of whom have been in the stair manufacturing business for years. Another important consideration in quality is color consistency. Wood is a natural product with normal variations in color and graining. We take great care to color match components, but these variations are part of the natural beauty of wood.

Care & Maintenance
All completed products are thoroughly inspected before
leaving our facility, however they have not been finished
and are therefore vulnerable to extreme weather conditions
that may cause wood to crack. In order to prevent problems
caused by temperature and relative humidity, keep your
stair parts in a constant temperature before they are
installed and finished.
