In connection with building a new staircase to the upper floor during the spring, I need to cut away part of an old firewall made of red brick.
Since this will take place in a hall in the middle of the house we live in, it is important to minimize dust formation as much as possible. Fine, red, brick dust is not something you want in the otherwise newly renovated house.
The cut will go from ceiling to floor, 2.8 m.
The question is then which method should be chosen?
- The large angle grinder with a diamond blade combined with an industrial vacuum cleaner seems like the first option.
- Then maybe a reciprocating saw with a masonry blade? Probably creates less dust?
- Some other tool, method?

An angle grinder helps a lot, but you'll definitely have dust in the house anyway. The speed of the diamond blade is simply too high and too much air is drawn around for your vacuum cleaner to handle. It's often difficult to combine a sufficiently tight cover around the blade while being able to see what is happening. The cookie jar model that is discussed on the forum works quite well, but much dust is missed. If you still proceed, you need to cover with plastic twice as much as you think is necessary and possibly wet the brick gently (machine plugged into JFB outlet!)
My vote definitely goes to the reciprocating saw with a carbide blade. It's easier to control how much dust gets into the air by adjusting the pressure you apply on the saw, and it's also possible to wet the brick without as much risk of getting fried. I bought a nice blade at Ax... when I had a similar challenge with aerated concrete.

If you want a neat edge, use the tiger saw. Otherwise, a regular hammer and chisel aren't too bad either. It takes time, but you keep the dust down significantly. No matter what, cover everything with plastic, and even more plastic. Another tip is to wear a disposable coverall specifically for this job and then dispose of it with the demolition debris. That way, you avoid most of the dust in your clothes as well.
I tested this method when I took down a mold-infested shed with sawdust insulation.

I can mention that I was cutting with an angle grinder OUTDOORS in a brick wall. It was unbearably dusty. So I had to stop. The reciprocating saw worked much better!
