Dear Danny, Elizabeth, Brenda, Juan, Carlos, and everyone at Complete Basement Systems,

We do not know how to thank you for your consideration and help during a very trying time on Long Island. Hurricane Irene could have been a tragedy for us and our home, but because of your competence, we had a job well done and it saved us not only great heartache, but great expense. We will definitely recommend your company very highly, not only because of your competence and courteous manner, but also because of your humanity towards Long Islanders.

Thank you and may God bless you always!

Sincerely, Carol and John
