I had confidence in Salvadore's expertise during the installation. I requested a follow-up to ensure the drain tile and sump pump were functioning properly a week after the installation. Jason Carlin came for a 5 o'clock appt and took the time to explain and answer all my questions. It was hot and he didn't try to hurry the meeting and really expressed true interest in making us a satisfied client. He recommended a dehumidifier from Thasher and checked humidity qualities in the basement to reglect his suggestion. This is something I will definitely be considering in the future. He also stressed the importance of yearly maintenance with Thrasher to protect our investment.
