It is a bit complicated @John Weidner but we have to sister the existing joists and create a channel in the floor to accommodate the drain line that is perpendicular to the joists.

This particular property was listed ambiguously on zillow as a 4 unit, but then digging around and google street maps revealed that it is in fact a 6 unit property, on a standard city lot, a 4 unit up front and a duplex perpendicular to it right behind it.

If you sand only in the direction of the grain, it doesn't fit into the edges where the floor boards are perpendicular to the walls.

This is referring to a street running perpendicular to an incline, so one house is much higher on the incline than the house across the street.

Hey Andy, a few pics of your house or even a drawing of the floorplan would be really helpful.1st question: is the common wall in-line (not perpendicular to) the roof ridge?

Alternatively if you have enough room to maneuver you could get a steel (or even a 6x6, if allowed locally) support beam perpendicular to your joists, supported by steel jack posts on footers.

We then positioned the stockings on top of the ice on the gutter and perpendicular to the direction of the gutter.

I just drove around third ward, in between Southmore and Blodgett perpendicular to Scott St., and it honestly looks kinda rough.

But that presumes your subfloor boards were T&G and that they were installed perpendicular to the joists.

At the "demolished wall areas, we will install the floor perpendicularly.
