We hired a well recommend concrete polishing co. to remove old mastic from bsmnt. floor, polish it all and epoxy coat. Was assured system had appropriate dust containment, but there still be some.

Anticipating some I stapled up plastic sheeting all aroundas "insurance". When they came they added a bit more.

The original proposal was that the machine was several hundred pounds but came apart for easier transport but still was not easy to get downstairs. I was expecting to prepare access to make it easier with floor protection and planking for stairway.

Job day comes and I am told the access prep was not needed and the machine was a 'new' one smaller and lighter but had no dust collection system. Instead they were relying on a heavy duty shop vac. Not with a HEPA filter system. They did do extensive vacuuming in the work area and the sheeting contained slot.

BUT...there is fine layer of dust everywhere else in the basement. Everywhere and on everything...including the FHA furnace area.

They will returning this week for the second coat. No $ has changed hands yet.

I am googling cleanup both DIY and professionals.

WWYD in this situation?

I would call the company and tell them that it's really looking great, but there is quite a bit of residual dust everywhere. So, please have your guys ready to do more vacuuming and cleaning up before applying the final coat of epoxy. Thank you very much.

Be polite to the workers when they arrive and you point it out, and thank them for good work.

Proceed with caution. If you don't already know, concrete dust is hazardous. Contains high amounts of silica and corrosive caustic.

Try to limit your contact, and your tenants.

Contractor should know better.

Smaller machine easier for them. No vacuum in it, they don't care if it's bad for you. Sounds familiar. If they still have to grind tell them you want the other machine in addition to vacuuming and removing dust from the whole place.

Thanks for the input. Proposal said grind floor apprx. 400 sq.ft. fill cracks, 2 part system sealer then epoxy, grey color. coat, re coat when cured. Clean up.

Verbal was the big machine almost ductless. Heavy and talked about how to get it down to basement and appx. time for full apps. I would take efforts to safeguard floor and staircase.

Read about silica today and am not happy with the report. Yes they cut corners with the job.

Ms. Ally. Calling servpro in AM. They are a franchise.

Hope you did OK in the storms

Besides being a landlord I'm also a licensed contractor. There are new Federal as well as local guidelines requiring

Jim: sorry to hear you missed the point. Contractor failed to provide service as promised and the result is bad.

I certainly expected some especially given the nature of the job.

UPDATE: contractor has gone radio silent since leaving on Wed. evening despite promises to return Friday despite our call for ETA.

Pro remediation coming Tues.AM for estimate.

That "PRO" remediation is going to cost a whole lot more than a HEPA filtered vacuum cleaner.

And be a LOT more hassle, that Could open up a can of worms.

Why a "pro"? What's wrong with two people with a bucket, wet mop and some rags? A new furnace filter?

1. Might need a third party estimate.

2) my reading on line suggests that it may be more difficult than I expect.

No final decision has been made.

Thanks to all.
