Commercial Diving Services in Ireland
Commercial diving services in Ireland cover underwater work that keeps ports, marinas, fish farms, bridges, and coastal infrastructure running. Divers inspect and repair hulls, propellers, intakes, moorings, pipelines, and sea walls, often in places where dry-docking is impractical or too slow. The work can be planned, such as a survey of a pier or a fish farm cage, or reactive, such as clearing a blocked cooling intake or recovering a lost item. Because the job happens below the waterline, the scope is rarely clear until a diver has seen the site. For that reason, commercial diving is a quote-after-visit service: a professional will usually need to assess depth, visibility, current, and access before giving a firm price. On ShamFix you can post your task, describe what you need, and browse provider profiles by county. Your task stays open for 30 days. Providers registered in this category can see it. You can then contact divers directly to arrange a site assessment and a written quote.
What shapes the price of commercial diving services
- Several factors shape the cost of commercial diving work, and none of them can be reduced to a single figure without a site visit.
- Depth matters: a shallow inspection in a sheltered marina is a different job from a deep or exposed coastal survey.
- Water conditions also count, including visibility, current, tide, and temperature.
- Access is often the largest variable: can the diver work from a pontoon, a boat, or a quay, or is a full diving spread with a support crew required?
- The condition of the structure or vessel matters too.
- A routine propeller inspection may be straightforward, while a corroded intake, a damaged mooring, or a hull with heavy marine growth takes longer and may need specialist tools.
- Materials and parts, such as replacement anodes, seals, or underwater epoxy, are additional.
- Finally, the volume of work affects price: a single small task is priced differently from a full survey across multiple locations.
- For all these reasons, a written quote after a visit is the normal way to price commercial diving in Ireland.
How long commercial diving services takes
Timelines for commercial diving in Ireland depend on the type of job and the weather. A small inspection, such as checking a propeller or a single mooring, can often be completed in a few hours once the diver is on site. A larger survey or repair may take a day or several days, especially if it involves multiple locations or requires parts to be ordered. Realistic start dates are usually governed by two things: the diver's existing schedule and sea conditions. Coastal work is weather-dependent, and a spell of wind or swell can push a booking back. Some jobs can be planned around neap tides or calm forecasts, while reactive work, such as clearing a blocked intake, may need a faster response. In general, expect a site assessment first, followed by a written quote, and then a scheduled date. For planned maintenance, it is wise to allow a few weeks from first contact to completion. For urgent work, ask the contractor directly about availability. Posting a task on ShamFix costs nothing today, and your task stays open for 30 days. Providers registered in this category can see it.
What to ask before you hire
- 01When you are hiring a commercial diving contractor in Ireland, ask for a written quote that breaks down labour, equipment, and materials separately.
- 02Ask whether the quote includes mobilisation and demobilisation, because moving a diving spread to a remote pier or harbour can add significant time and cost.
- 03Ask about insurance: you want to see evidence of public liability and employer's liability cover, and, where relevant, professional indemnity.
- 04Ask whether the contractor is VAT-registered and whether the quoted price includes or excludes VAT.
- 05Ask who tidies up after the job.
- 06Underwater work can leave ropes, buoys, tools, or debris behind, and you should agree in advance who removes them and how the site will be left.
- 07Ask which professional body the diver is a member of, and ask to see certification for the specific type of diving required, such as inshore or offshore.
- 08Ask how they will report findings, whether by video, photographs, or a written survey, and whether that report is included in the price.
- 09Finally, ask what happens if the work takes longer than expected, and how additional time or materials will be charged.

Commercial diving services questions people ask
What does a commercial diver actually do on a typical job in Ireland?
A commercial diver carries out underwater work that cannot be done from the surface. This can include inspecting hulls, propellers, and intakes, repairing moorings, cleaning marine growth, or surveying piers and sea walls. In Ireland, many jobs are in ports, marinas, and fish farms. The diver works from a boat, pontoon, or shore, often with a support person on the surface.
Do I need a site visit before I can get a price for commercial diving?
Yes, a site visit is usually necessary before a firm price can be given. Underwater conditions such as depth, visibility, current, and access vary greatly, and these factors directly affect the time and equipment needed. A diver can assess the site and then provide a written quote. In some cases, a preliminary video survey may be enough for a rough estimate.
How is commercial diving priced in Ireland?
Commercial diving is priced on a combination of depth, access, water conditions, and the volume of work. Labour, equipment, mobilisation, and materials are typically itemised in a written quote. There is no standard hourly rate that applies to every job. For a small inspection, the cost may be modest, while a full survey or repair with a support crew will be higher.
What insurance should a commercial diving contractor have?
A commercial diving contractor should have public liability and employer's liability insurance, and in some cases professional indemnity. You can ask to see a certificate of insurance before work begins. If the contractor employs other divers or support staff, employer's liability is essential. It is reasonable to request a copy and to check that the cover is current.
Can commercial diving work be done in winter in Ireland?
Yes, commercial diving can be done in winter, but weather and sea conditions may limit when it is safe. Cold water, shorter daylight hours, and rougher seas can affect scheduling. Some sheltered inland or harbour jobs are less affected. A contractor will advise on the best window and may need to reschedule if conditions are unsuitable.
How long does a commercial diving job usually take?
A small inspection may take a few hours on site, while a larger survey or repair can take a day or more. The total time includes mobilisation, diving time, and demobilisation. Weather and visibility can add delays. For planned work, allow a few weeks from first contact to completion, and ask the contractor for a realistic schedule.
