H S Certified Marine Services at a glance
Reviewers frequently cite the shop's quick turnaround times, fair pricing, and knowledgeable staff as primary benefits for services like winterization, engine work, and installations. However, lower-rated feedback highlights issues with communication, including difficulty reaching the business by phone, lack of online contact information, and instances of perceived carelessness with customer property. The overall 4.7 rating from 55 reviews reflects a generally positive experience despite these isolated complaints.

I can't even tell you how terrible of a shop this is it will cost a thousand dollars to fix the damage they caused. Ps they won't take their shoes off in your boat. They left my whole fuse panel on the floor of the boat and left the key on in the boat and left the battery switches on 2 completely dead batteries.
