I HIGHLY Recommend this company! They came to my house and did everything they said they would do! They removed 20 years of layered stain from my 500 square foot patio, COMPLETELY, contained the glass sand they use in their removal process, then completely cleaned it all up. They were the hardest working people I've ever met and treated me with the highest kind of professionalism. They also, protected my property including my home, grass and gardens from damage. YOU GUYS ARE THE BEST!!
