At Top To Bottom Inc, we have been caring for boats in Bellingham, Washington since 1986. Forty years in the marine industry teaches you one thing above all else: the owners who stay ahead of maintenance problems are the ones who spend more time on the water and less time dealing with costly surprises. An annual review of your vessel is not just good practice. It is the foundation of responsible boat ownership.
Whether your boat lives at Squalicum Harbor, a nearby marina, or is trailered between seasons, this checklist covers the areas that deserve a close look every single year. And if anything on this list is beyond your comfort level, our team at Top To Bottom is ready to help.
Start Below the Waterline
The hull is where the most serious and least visible problems develop. Because this area spends all of its time submerged, fouling, corrosion, and damage can progress significantly before most owners notice anything is wrong. This is exactly why haul-outs exist, and it is the first thing we address when a boat comes into our facility at Colony Wharf.
Inspect and Refresh Your Bottom Paint
Anti-fouling bottom paint is not a set-it-and-forget-it solution. It degrades over time, and once it loses effectiveness, marine growth attaches to the hull and begins dragging on your performance and fuel efficiency. An annual inspection tells you whether your existing coating is still doing its job or whether it is time to strip it back and reapply.
At Top To Bottom, we provide comprehensive bottom painting services using quality products from trusted brands like Interlux and Sea Hawk. Our process includes cleaning, full inspection, and fresh anti-fouling paint application so your hull is properly protected heading into the season.
Check Zincs and Replace as Needed
Sacrificial zinc anodes are your boat’s defense against galvanic corrosion. They corrode so your hull, prop shaft, and underwater hardware do not. If your zincs are more than fifty percent depleted, they need to be replaced. This is a straightforward job during a haul-out but one that gets overlooked far too often.
Propeller and Running Gear Inspection
Dings, bends, and missing material on a propeller do more than look bad. They create vibration, reduce efficiency, and put stress on your drivetrain. A full running gear inspection should be part of every annual review, and our dive service team can handle underwater inspections when a full haul-out is not in the plan.

Hull and Fiberglass Condition
Above the waterline, your hull takes a beating from sun, salt, and impact. Gelcoat that goes without attention can crack, fade, and eventually allow water intrusion into the fiberglass laminate beneath. Catching problems at the surface level is far less expensive than dealing with structural damage later.
Fiberglass and Gelcoat Repair
Our fiberglass boat gelcoat repair service addresses everything from cosmetic surface crazing to deeper structural damage. Our technicians use advanced repair techniques and high-quality materials to restore both the appearance and the integrity of the hull. The goal is always a repair that holds up to real-world use, not just one that looks good on the day.
Detailing: More Than Appearances
Boat detailing is often treated as a luxury, but it plays a practical role in protecting your vessel. Oxidized surfaces, contaminated nonskid decks, and neglected interiors all contribute to faster degradation of your boat’s materials and overall value. Our detailing services use premium products and proven techniques to clean, polish, and protect every surface, keeping your investment in the condition it deserves.

Mechanical Systems Review
A boat that looks pristine but has a struggling engine or unreliable electrical system is not ready for the water. Mechanical reliability is a safety issue, not just a convenience, and the mechanical side of your annual checklist deserves just as much attention as the exterior.
Engine and Drive System Inspection
Fluid levels, belts, hoses, impellers, fuel filters, and cooling systems all need to be evaluated at the start of each season. Our boat mechanical repair team works with all major brands and models, handling everything from routine troubleshooting to complete engine overhauls. If your engine has been sitting since last fall, a thorough inspection before your first launch is the right call.
Bilge, Pumps, and Through-Hulls
Bilge pumps that fail in the field create emergencies. Through-hull fittings that are seized or corroded can fail under pressure. These are not glamorous parts of the annual checklist, but they are among the most important. Each fitting should be inspected, each pump tested, and any seacocks that feel stiff should be serviced before the boat goes back in the water.

Brightwork and Woodwork
Teak and other wood surfaces require consistent care to maintain their appearance and resist moisture damage. Neglected brightwork does not just look tired. It can crack and eventually allow water to work its way into deck structures.
Annual Varnish and Wood Maintenance
Our brightwork services cover the full process of cleaning, sanding, and varnishing teak and other wood surfaces. Done properly and on a regular schedule, brightwork maintenance keeps wood looking beautiful and structurally sound for years longer than wood that goes without attention.
