Drain Maid™ BioSmart® Treatment


Clean drains and keep them free-flowing with naturally-occurring bacteria with BioSmart®. This natural solution is made up of bacteria that thrive on the grease, oil and organics that are found in every home’s drains. Buy a year supply and get one bottle FREE! Contact us for more details.

Our Clog-Free Guarantee


Neptune Plumbing & Heating guarantees that BioSmart® will get the job done! If you experience a clog even after one of our cleanings and using BioSmart® every month for a year, we will provide you with a free drain cleaning on the original drain.

Our 100% Satisfaction Guarantee


Our reputation for professional and quality service is unwavering. Furthermore, if our plumbers smoke, swear, do not wear shoe covers, remove their shoes or leave your home in an unacceptable, messy state, you do not have to pay the service fee.

If our repair fails in the first year, we will repair it again absolutely free!
