Water ingress
Worn seals or degraded glazing can allow water to enter the cabin.
Restore clarity, seal integrity and performance
Boat hatches are constantly exposed to sun, salt and weather. Over time, the acrylic or glass can become scratched, cloudy or cracked, seals can fail and hardware can deteriorate.
While many owners assume the entire hatch or portlight needs to be replaced, in most cases it can be professionally repaired and reglazed.
At ALFAB, we specialise in boat hatch repair and reglazing, replacing the glazing while restoring the existing hatch frame and components wherever possible.
The result is a hatch that looks and performs like new — often at 70–80% less than the cost of replacing the entire unit.
What is Boat Hatch Reglazing?
Boat hatch reglazing involves removing the original acrylic or glass from a marine hatch and replacing it with new marine-grade glazing materials.
The hatch frame and hardware are retained and refurbished where required, restoring the hatch to full function and appearance.
This process is commonly used when hatches become:
- Scratched
- Cloudy from UV exposure
- Cracked or damaged
- Leaking due to failed seals
Reglazing allows the hatch to be restored without replacing the entire assembly. Especially useful when the original hatch (or portlight) is a custom made or irregular size.
Glazing Materials for Boat Hatches and Portlights
Hatches and portlights can be reglazed using materials that match the vessel’s original specifications.
Common glazing materials include:
PMMA / Marine Acrylic
Lightweight, durable and commonly used in marine hatches.
Thermally Toughened Glass
Strong safety glass used where higher strength is required.
Structural Laminated Glass
Multi-layer marine glass designed for safety and structural performance.
All reglazing is completed using like-for-like materials to meet the original ship standards.
Common Reasons Boat Hatches Need Repair
Boat hatch or portlight repairs are typically required due to:
Reglazing vs Replacement
Cost Comparison for non-standard, high production products
Replacing an entire hatch assembly can be expensive, particularly for older or discontinued models. Reusing an existing hatch can also save you the time and hassle of modifying the opening to fit a replacement.
Typical cost savings when reglazing include:
Plastic / composite hatch construction
Up to 80% cheaper than full replacement.
Aluminium hatch construction
Approximately 70% cheaper than replacing the entire hatch.
Hatch repairs and Portlight repair turnaround time
Typical turnaround time for hatch reglazing or repairs is 30–40 working days.
This can vary depending on:
- Hatch size and shape
- Condition of the hatch
- Glazing materials required
- Hardware repairs
- Workshop workload
What marine hatch components can be repaired or replaced?
During a hatch refurbishment or repair, we can service or replace:
- Acrylic or glass glazing
- Gas struts and springs
- Rubber seals and gaskets
- Hatch latches and catches
- Hinges and hardware

Portlight refurbishment can include:
- New glazing
