Needs to be filled w something...but not cement.

Carpets are new but they are almost everywhere... 2200 sq.f of floors with stairs...I was told it doesn't make sense to replace carpets in rental and it's better to go with cheap laminate, The best quote I got from contractors was over 5K - many stairs on top of square footage.

Due to the risk of hurricanes we need to build the main structures from block, steel and cement. 

They sell a rounded stair that you can stain and then put that on the tread/landing/flat part of the stairs.  

The garage apartment we had intended to turn the garage area into a living space, put in a stair case and make it a 3/2 house. 

Hi everyone,Who is responsible to clean the common areas, hallways and stairs of a Fourplex?

Do they come in through the front door, walk through the house, and go down interior stairs?

However, what can I do with these stairs? 

I was originally thinking of sealing the whole plaster or cement-like mixture but wasn't too sure about the idea.

Also, my washer and dryer are down stairs, should I avoid entering down there at all or would it be acceptable for to me to say I need to use the washer/dryer once a week?
