I can’t say enough about how this company saved us in an emergency situation! From the owner, Bart, to Lukas & his crew everyone was friendly, professional, helpful and efficient. Highly recommended!
Had a smooth and positive experience getting a quote for removal of my 75+ year old cast iron oil tank from a crawlspace and getting a brand new exterior tank installed. Owner Bart and his staff were responsive and professional. They were the most reasonable company I got a quote from (I got over 5 quotes for this job!). Work was clean, high quality, and took half a day exactly as expected. Very pleased with the service.
I had an excellent experience with Complete Tank LLC from start to finish. The entire process was smooth, professional, and stress-free. From the initial communication to the day of the tank removal, their team was responsive, courteous, and incredibly helpful. They clearly explained everything, provided a fair and transparent price, and showed genuine professionalism throughout. On the day of service, they arrived within the promised window and made sure everything was handled efficiently and with care. It was clear they take pride in their work and truly value their customers. I especially appreciated how accommodating and easy they were to work with, it made a potentially stressful situation feel simple and manageable. I would absolutely recommend Complete Tank LLC to anyone needing tank removal services. Thank you again for such a great experience!
Complete Tank LLC did an excellent job replacing our tank, even on an extremely cold day. The crew was professional, efficient, and respectful of our home. They completed the work smoothly and left the area spotless afterward. Truly appreciate their reliability and attention to detail—highly recommend them.
I used Complete Tank to relocate an existing oil tank from one side of my basement to another as a part of a renovation project. I had a very hard time finding any contractor that would table such a job but they were more than willing to do so. The pricing was fair and the work done neatly. The office staff and owner Bart are great to work with. I highly recommend them for any oil tank needs.
