Rugs, Carpets and Carpeting - Should I Try to Salvage the Tack Strips?

I'm in the process of converting an old mother-in-law apartment into a couple of bedrooms.

That part of my house is built on a slab and after pulling back a corner of the wall-to-wall, I can see that they attached the tack strips through some old glue-down tile with nails into the slab.

It appears from reading back that I probably should try to leave the existing tack strips in place, though one line would have to move because that part has been extended and some more would have to be added because there will be a hallway in a place, where none exists at this time.

I'm fine with the idea of leaving the tack strips and would probably accomplish this by cutting the carpet to accomodate the new walls and by removing the remainder of the carpet at the last minute, but if they're really not going to be useful down the road, then I might as well pull as I go.

So, I guess my question is simple;
Am I reading old posts correctly and is it advisable to try and save the tack strips, whereever possible?


Thanks in Advance

The way I read this is; there is going to be a tack strip left across a walk way, even if it is covered with carpet you sure would not to want to step on it in your bare feet after the carpet gets squished/matted down. Pull as you go.

If you intend to re-install the old carpet where it was, as long as the strip is secure and serviceable, you can leave it in place and use it again. Even if you intend new carpet, tack strip normally doesn't wear out and can be used again. I often find the old stuff to be unserviceable if it has gotten wet at some time and the pins are badly rusted or the wood is deteriorated. But, if it looks to be in good shape and is well secured, why remove it if you don't have to? Removing or re-using is not a matter of mechanical strength or anything. It just means less work and expense.
