Dave B worked for over 2 hours unclogging my kitchen sink. This was not an easy task and he worked diligently until he solved the issue. The entire time he was here, he made sure that all the equipment he brought in or out was covered in order to keep my house clean. He explained everything he did. Was extremely polite and patient. The entire experience was wonderful. If I ever needed a plumber again, I would not hesitate to call them.
