Fixing a hole in a fiberglass boat can be a costly repair, but the exact cost depends on several factors:
- Size of the hole
- Location of the hole
- Level of damage to the fiberglass
- Complexity of the repair job
- Whether you do it yourself or hire a professional
Generally, small holes, minor damage, and simple repairs will be cheaper, while large holes, major damage, complex jobs, and hiring a pro will increase the costs. Proper fiberglass repair requires specialized materials and knowledge to do correctly.

Cost Factors
Size of the Hole
The size of the hole is a major cost factor. Small holes of just a few inches across can often be repaired for under $100 in materials if you do it yourself. Larger holes of a foot or more can require between $200-$500 or more in repair materials alone.
Labor costs also go up for larger holes, with small holes taking a few hours to fix, while large holes may take days and hundreds of dollars in professional repair labor.
Location of the Hole
Where the hole is located also impacts repair costs. Holes above the waterline are easiest to access and fix. Damage below the waterline is much more difficult to access and repair, driving up costs.
Hull holes are more straightforward to fix than holes in complex areas like the keel or rudder. Holes below the waterline also raise issues of sealing and preventing leaks that add to the complexity and cost.
Level of Damage
Just puncturing the outer gelcoat layer is a minor repair. But if the hole extends deeper into the fiberglass laminates and mats, it complicates the repair process and materials needed.
Larger holes may have spiderweb cracking or delamination surround the hole that also needs fixing. Major structural damage like a gouge from hitting a rock will cost much more to repair than a small puncture from running aground.
Complexity of the Repair
Simple hole repairs involve patching and sealing the hole. More complex fixes require fiberglass reconstruction and rebuilding of stringers or hull integrity. Complex jobs take substantially longer requiring more repair materials and expertise.
Cosmetic repairs just to make it look nice are cheaper than structural repairs to restore strength and functionality. The complexity drives up expenses for materials and pro labor time.
DIY vs Professional Repair
Doing it yourself will always be cheaper than hiring a professional. However, fiberglass repair requires specialized tools, materials, and techniques to achieve lasting repairs. DIY repairs often look amateurish or fail to properly adhere.
Pros have the expertise, tools, and materials to properly fix fiberglass holes and achieve seamless, structurally sound repairs. However, expert labor, shop fees, and travel costs mean paying a professional will cost more than a DIY job.
Cost Comparison Chart
| Repair Type | DIY Cost | Pro Cost |
|---|---|---|
| Small hole above waterline | $50 – $150 | $200 – $400 |
| Medium hole below waterline | $150 – $300 | $600 – $1,000 |
| Large hull hole with structural damage | $500 – $1,000 | $2,000 – $4,000 |
| Complex rudder or keel repair | $1,000 – $2,000 | $5,000 – $10,000 |
This table compares typical costs for different fiberglass boat hole repairs by do-it-yourself versus hiring a professional repair shop. The costs show how repair expenses can range widely based on the factors discussed.
DIY Fiberglass Boat Hole Repair Cost Breakdown
For do-it-yourself repairs, here are typical material costs:
Small Hole:
– Fiberglass cloth – $20
– Resin quart – $30
– Gelcoat pint – $15
– Mixing cups, brushes, gloves – $10
– Sandpaper, masking tape – $15
– Total: $90
Medium Hole:
– Fiberglass cloth – $40
– Resin quart x 2 – $60
– Gelcoat quart – $25
– Hardener & catalyst – $20
– Mixing cups, brushes, gloves – $15
– Sandpaper, masking tape – $25
– Total: $185
Large Hole:
– Fiberglass cloth yards – $100
– Resin gallons – $180
– Gelcoat quart x 2 – $50
– Hardener & catalyst – $30
– Mixing cups, brushes, gloves – $20
– Sandpaper, masking tape – $50
– Power sander rental – $75
– Total: $505
The material costs scale up with the size of the repair. Small holes may only require a single quart of resin, while bigger jobs need gallons. More fiberglass cloth is also required. Tooling and supplies add to costs. Renting equipment for large repairs also adds expenses.
Professional Fiberglass Boat Repair Costs
Hiring a professional for fiberglass boat hole repair typically involves:
– Shop fees – $50-$100/hour
– Expert labor – $70-$125/hour
– Travel fees if mobile service
– Materials at retail prices
– Shop supplies/tools
– Insurance markups
Labor time is a major cost for pros. Simple holes may take 2-4 hours while complex jobs can require 40+ hours at professional shop rates. Material costs also go up when purchasing at retail rather than DIY discount.
Factor in shop overhead, insurance, and travel, and professional repair costs quickly skyrocket compared to DIY. While hiring a pro ensures proper repairs, it comes at a premium cost.
Saving on Professional Repairs
If hiring a pro, here are tips to reduce fiberglass boat hole repair costs:
– Get quotes from multiple shops for comparison
– Ask about hourly rates to minimize labor time
– Negotiate discount for basic shop rate vs high-end pros
– Avoid additional travel fees by trailering to the shop
– Supply your own materials purchased at discount outlets
– Complete prep work like cleaning and sanding yourself
– Ask about apprentice labor for discounts from full pro rate
– Get all agreements for rates and expected costs in writing
While professional repairs have high baseline costs, you may be able to save hundreds with the right negotiations and cost-saving measures.
Factors That Increase Repair Costs
Be aware of these factors that can drive up the costs of fiberglass boat hole repairs:
– Major damage beyond just a hole that requires extensive reconstruction
– Structural repairs to stringers, keel, or rudder
– Holes located below the waterline or in hard to access areas
– Replacing damaged hardware like rails, cleats or through-hulls
– Additional cosmetic work like matching gelcoat colors and textures
– Fixing flaws in prior improper repairs
– Shipping or trailering long distances to a shop
– Emergency or rush repairs requiring overtime and bonuses
These situations mean much more time, materials, and expertise required to fix the hole and damage. Be prepared for potentially high costs if they apply.
How to Estimate Repair Costs
To estimate fiberglass repair costs yourself:
– Carefully examine hole size, area, and extent of damage
– Note location especially if below waterline
– Assess if structural, cosmetic only, or complex multi-layer damage
– Research DIY material costs for similar projects
– Get professional shop quotes for labor + materials
– Ask for cost breakdowns, hourly rates, and time estimates
– Compare multiple shop estimates and average costs
– Factor in any additional work needed beyond hole repair
– Pad estimate by 25% for contingencies and cost overruns
Having an accurate idea of repair scope and getting multiple professional estimates will give you the best sense of potential costs. Build in padding for surprises and you can budget for the boat hole repair.
Saving Money by Repairing Small Holes Quickly
The best way to save money on fiberglass boat repairs is preventive maintenance. Addressing small holes, scrapes, and cracks as soon as they occur prevents further damage and major repairs down the road.
Check over your boat frequently. Carry a fiberglass repair kit for minor touch-ups. Follow manufacturer inspection and maintenance recommendations. Haul out annually to inspect below waterline surfaces.
Deal with problems proactively. Grind back cracks in gelcoat before they spiderweb. Seal nicks and punctures with resin before moisture intrudes. Make temporary repairs to stabilize bigger holes until permanent professional repairs can be scheduled.
Prompt action to fix small holes as they happen will ensure they don’t become big expensive problems later. Ounces of prevention are worth pounds of cure for boat hole repairs.
Conclusion
Fixing a hole in a fiberglass boat can range from a quick DIY repair to a major expensive rebuild. On average expect to pay $50-$500 or more for do-it-yourself fixes, depending on the hole size and complexity.
Professional repairs typically run $200 to well over $1,000, with structural damage, underwater holes, and complex jobs hitting the high end. Get multiple estimates and understand all repair costs factors to budget for your boat hole repair.
Preventive maintenance is key. Addressing small holes and damage promptly avoids having big problems down the road. Keep your boat well maintained and make repairs as soon as needed, and you’ll save substantially on major fiberglass repairs.
