Frequently Asked Questions
Please reach us at max@maxwaxmarine.com if you cannot find an answer to your question.
Most minor gel coat repairs, chips, small cracks, and surface scratches, are completed in 1–2 days. More extensive damage such as osmotic blisters or structural fiberglass repairs typically takes 3–7 days depending on the severity and the size of the affected area. We'll give you a specific timeline during your free on-site assessment.
Yes. MaxWax Marine specializes in precision gel coat color-matching. Using paint-mixing technology and our experience with hundreds of boat brands and hull colors, we blend custom gelcoat that is virtually indistinguishable from the factory finish, even on aged or faded hulls where the color has shifted over time.
Repair costs depend on the size, depth, and location of the damage. Minor gel coat chips and scratches start around $200–$400. Stress crack repairs typically range from $400–$1,200. Structural fiberglass repairs and full panel refinishing are quoted individually after inspection. Contact us for a free, no-obligation quote — no estimate fees, ever.
Both. We work out of our Chelsea, MA facility and on-location at marinas throughout Greater Boston. For smaller repairs, bringing the boat to our shop gives us the best-controlled environment for color-matching and finishing. For larger yachts or in-water repairs, we come to you. Contact us to discuss the best option for your situation.
We service all fiberglass boat types and brands, including Azimut, Sea Ray, Boston Whaler, Grady-White, Pursuit, Regulator, Hinckley, Viking, Cabo, and more. From 20-foot center consoles and bowriders to express cruisers and large sport-fishers; if it's fiberglass, we can repair it.
