decontamination and biohazard cleaning services reviews
Samantha, Herderson, 01/20/2020
I can not say enough how truly thankful I am for this company! I needed help urgently and Danny answered the phone after business hours (thank you again!) and was beyond patient and accommodating. They were very thorough with their work and made sure I was satisfied. Something I really appreciated was how discreet they were with their job. It was a tough time for me but they made sure to put my feelings first and made me feel at ease and comfortable. Thank you for everything!

Tenants left all floors covered in pet urine, feces, food. Every sink, toilet BLACK. Kitchen was caked in filth. Sight, smell overwhelming! Danny and crew were amazing, professional, fast, thorough & affordable. Rescued me and my home. Very kind people.
