First, I think the link in your signature is either wrong or outdated because it is taking me to Polish website. http://www.ocwp.co/ looks more accurate.

We have great communication; I clearly state and write down what I want done and when I inspect upon completion, it always looks great.They can do pretty much everything: paint, flooring, concrete repair, roofs, windows, plumbing, etc.

Third bathroom from scratch in my basement which involved busting up the concrete floor, moving the main stack (and a cleanout  the front of the a semen while I was at it).

Add rocks/or concrete pad as per what your city will allow.

The city didn't want to haul off the chunks of concrete--and it was their tree that was causing the problem.

The long pants will not keep the fleas off of you.You need to duct tape wrap around the shoes and hands before going in the property.Set off a bunch of flea bombs.If the carpet is bad you will need to replace it and the pad because of the eggs that will rehatch.Depends on how old the carpet is.After leaving the house they throw away the suit in the trash before getting in the car to leave.Otherwise they can track back to your house where you live.Ken you can try to make tenants do flea collars and all of that but good luck getting them to comply.People are going to live how they live no matter what you say.This is why it's important to see how they are living where they are currently at.People can look polished in person but there room can look like a hurricane hit it.For these people there work persona and there living at home persona are worlds apart.

Say there's nothing but wood and concrete.

I was going down to the laundry room and he told me to stop at the bottom stem , he just repainted the concrete floor because he spilled stuff on it and it bothered him .

Does it require any foundation/concrete work? 

Older home, uneven floors as well, I hear thicker is better for uneven concrete sub floor.
