While Texas winters are milder than up north, **GEICO and BoatUS data show Texas ranks #1 nationally for freeze-damage insurance claims** — mostly from owners who skipped winterization.
Even a single cold night can cause water to expand and crack blocks, split hoses, or destroy cooling systems. Professional winterization protects your investment.
Each package builds on the next, adding more layers of protection:
- FreezeGuard: Essential freeze protection — drain, fog, and stabilize.
- SystemShield: Adds oil, fuel, and gear lube service.
- TotalLock: Adds full mechanical inspection and 20-point vessel check.
- TotalSecure: The all-in-one — shrink wrap, storage, and spring dewinterization.
Dewinterization is the spring startup process — flushing antifreeze, reconnecting systems, checking for leaks, and verifying function.
We only guarantee winterization work when we also perform dewinterization, ensuring we verify the system end-to-end.
Yes — our mobile winterization team travels to marinas, storage facilities, and homes across Lake Texoma.
Some services (like gear lube or impeller changes) require the boat to be on a trailer or lift, not in the water. Mobile rates apply. ($75 min travel fee, $2.50/mi)
While marine approved bilge heaters are a good idea, they aren’t a substitute for winterization. Power outages, tripped breakers, or temperature swings can still freeze and crack components.
Many Texas freeze claims happen because heaters failed during sudden cold snaps or power outage.
Our 20-point inspection checks:
-
- Battery & wiring connections
- Navigation & interior lights
- Propeller hub & shaft
- Steering and tilt/trim
- Hull, thru-hulls, and fittings
- Bilge pump & float switch
- Throttle & shift linkages
- Fuel lines and primer bulb
- Blower, belts, hoses, and zincs/anodes
- Deck hardware, vents, alignment, safety gear
You’ll receive a summary report with any recommended maintenance.
As early as possible — once temperatures dip, appointments fill quickly.
We start scheduling in late summer, and prime weeks typically sell out. Don’t wait until the first freeze warning.
Package pricing reflects labor only. Materials (antifreeze, oil, filters, stabilizer, parts, etc.) are billed separately. We won’t do any additional work without providing you an estimate first.
