Default What is the best way to cut floor exactly along wall?

I'm dealing with a trailer house with about 15 feet of bad floor along

one side. I recently replaced the floor in the water heater closet in

that trailer, and used a wood chisel along the wall. Just that 30"

closet took hours. I'm trying to find a better way. A circular saw

cant get close enough. I tried an angle grinder with grinder wheel,

which worked but filled the whole house with smoke and was real slow.

I do have access to one of those Multi Function oscillating tools from a

friend. I've never used one of them, so I dont know if that would work,

and of course I dont want to rip up the wall either. I did see about a

4inch circular saw blade at the hardware store, I was wondering if I

could put one of those blades on my angle grinder and use that. But I

thought I'd ask if anyone has a better idea.

The floor is made from 3/4" particle board, but will be replaced with

3/4" plywood. (treated plywood by the door, which is where the floors

always go bad in these trailers). However this trailer had a roof leak

(which is now repaired), so that is why there is such a large repair

The goal is to just remove 4" from the wall the entire length of the bad

area, and put down the plywood. I want to get right up to the wall to

remove all the bad flooring and so I have as much of the 2x8 joist

exposed to fasten the new plywood. I may still add blocks of 2x4

between each joist so there is more to nail to.

I'm want to remove a 4" strip but you say a circular saw

can't get close enough. Man, that must be some whopping big saw you have,

I've never seen one that couldn't cut 4" away from a wall; how close can you

cut if you turn the saw 180 degrees and go in the other direction?


That's exactly what I thought too. I've used a circular saw to
cut plywood up against a wall and the typical 7" circular saw
can get a lot closer to a wall than 4". Probably less than an
inch, if I remember correctly. Maybe the 4" was mistyped and he
meant something else?

The only problem with the circular saw is you can't get all the
way into corners.
