I chose Advanced Basement Systems because my daughter and son-in-law had two service calls by them, and they were extremely pleased. I did get a second quote, but Advanced Basement Systems were very thorough, and I especially appreciated receiving their booklet explaining and outlining all their services, as well as mentioning further safeguards for a dry basement. All the people I spoke with were pleasant, and answered all my questions; I really appreciated the communications and being treated without condescension. Thank you Kevin and to your assistant for an exemplary job from start to finish.
