Floor, Roof and Ceiling Joist Repair Stamped Drawings

JOIST REPAIR

We specialize in providing engineering stamped drawings for joist repairs.
​
Canadian Building Codes allow for the notching and drilling of floor joists to allow the passage of piping, ducts and other services.  We provide engineered drawings for notching and drilling that was not done as per code.

NOTCHING AS PER CODE

Notches in roof, ceiling and floor joists are allowed in the top of the member within ½ the depth of the 
joist size from the  edge of bearing.  
​
Notches are not permitted to be deeper than ⅓ the depth of the framing member unless the framing  
member has been increased in size by the size of the notch.

DRILLING AS PER CODE

Holes drilled through floor, ceiling or roof framing  are not to exceed ¼ the depth of the member. The holes 
are not to be located within 50 mm (2 in.)  from the edges  unless the framing member size has been  
Increased  by the size of the hole.  
​
Holes are required to be located at least the size of the hole width apart.
