I think that is a bit harsh...I have followed many of Michael's posts, and I feel he has contributed on many occasions with good info.

I get nothing down, order my hazardous chemicals they choose, and then they never let me do the job, I eat hundreds in materials I cant return!!

A lot has to do with time of the year and if they have kids in school or moving there would be holidays or very harsh weather outside ( extreme heat or cold etc.)

(be harsh if need be)Am I being a baby ?

Chemical/Petroleum PlantsIs it mostly single family homes, or are there small multis (like 2-4 plexes) and/or apt buildings too?

People are still using poly lines for supply lines and they will pit & leak from the chemicals in our water supplies...my contracting company gets at least 1 or 2 calls a month for floods caused by a broken supply line so it's best to upgrade the lines.

Lessee agrees not to store any explosive chemicals or hazardous materials in the rental.

If the outside needs as much work as the inside then costs can go much higher.Labor costs and materials vary by state and the property is a case by case basis.In some states with harsh winters getting contractors to do anything is tough during that time and your labor rates will go way up.

Your lease should already address the use of chemicals and toxic materials, inside or out.

If they dumped any hazardous waste as well and not just trash the county or city will get more involved.In our old subdivision there were some people dumping illegal chemicals down the storm drains.The water division came out and they eventually caught the businesses doing it and arrested them.
