Drainage trouble rarely waits, and Ireland has no shortage of firms to call. City unblockers, rural septic and sewage specialists and testing firms for the awkward jobs in between all do different work.
This shortlist gathers Irish drainage companies worth considering, with a note on who each one tends to suit and what their public ratings say. Treat it as a starting point, then talk to two or three before you book.
#1. Capcon Engineering Ltd.
Capcon Engineering tops this shortlist and is our featured pick. The firm is a construction and engineering company based at Maynooth Business Campus on the Straffan Road in Co. Kildare, which puts it within easy reach of Maynooth, Leixlip and Celbridge and handy for much of north Kildare and west Dublin.
Drainage jobs do not always sit alone. If your problem is tied to groundworks, a new connection, a site layout or an extension, a firm working across construction and engineering can be a more practical first call than a single-issue unblocker. Ask how they scope drainage work and what they handle in-house.
Their public rating is 4.5 out of 5 from a small number of reviews, so treat the score as a pointer rather than proof. Read the detail yourself, ask about recent drainage projects and compare their approach with two or three others on this list before you decide.
- Rating: 4.5/5 (2 Google reviews)
- Address: Maynooth Business Campus, G2, Straffan Rd, Moneycooly, Maynooth, Co. Kildare, W23 V2P5

#2. ProDrain
ProDrain is a dedicated drainage service operating from the River Court Business Centre on Cornmarket Row in Limerick city. The base is central, close to the main routes in and out of the city, so jobs across Limerick and the suburbs should not involve long travel.
A specialist drainage firm is usually the better call when the problem sits underground rather than at a sink or toilet. Typical work in this category covers blocked drains, drain cleaning and camera investigations, so ask ProDrain which of those they handle and how they charge for the first visit.
Their public rating is 4.9 out of 5 from 74 reviews, a decent sample for a city firm. Read the recent comments for a sense of how they communicate, then weigh them against one or two others before you book.
- Rating: 4.9/5 (74 Google reviews)
- Address: center, River Court Business Centre, Cornmarket Row, Prior’s-Land, Limerick, V94 R8Y4
- Phone: +353877121277

#3. Drain Away 2 Day
Drain Away 2 Day is a Waterford city option, based at Grantstown off the Dunmore Road. That side of the city suits quick access to the outer suburbs and the main routes out across the county.
They sit squarely in the drainage service category, the sort of firm you call for a blocked line, a slow drain that keeps coming back or a general clear-out. Ask what their call-out covers, whether camera work is part of the visit or priced separately, and how far across the county they travel.
The public rating is 4.8 out of 5 from 161 reviews, one of the larger review counts on this shortlist. Volume does not tell you everything, but 161 data points carry more weight than a handful.
- Rating: 4.8/5 (161 Google reviews)
- Address: 11 Garranmore, Dunmore Rd, Grantstown, Waterford, X91 A9CE
- Phone: +353862540358
- Website: drainaway.ie
#4. Walsh Waste & Recycling
Walsh Waste and Recycling works from the Deerpark Industrial Estate in Co. Galway, convenient for Galway city and the towns around it. The firm spans waste management as well as drainage, with listed categories covering debris removal, drainage work and general waste collection.
That wider brief can help where a drainage problem overlaps with waste: a cleared site, a flooded yard with debris to remove, or a property clean-up alongside the drain work. If your job is a straightforward blockage and nothing else, a pure drainage specialist may suit better. If there is more to shift, a combined firm is worth a look.
Their public rating is 4.9 out of 5 from 122 reviews, a strong showing for a multi-service firm. Before booking, ask how the drainage side of the business is organised and who you would deal with on the day.
- Rating: 4.9/5 (122 Google reviews)
- Address: Walsh Waste Ltd, Deerpark, Deerpark Industrial Estate, Co. Galway, H91 RH31
- Phone: +35391840840
- Website: walshwaste.com
#5. Glancy Enviro
Glancy Enviro is based outside Longford town at Clonterm, and its listed categories tell a clear story: septic system service, sewage disposal and water tank cleaning. That points to a firm built for properties off the mains network as much as for standard drain work.
If your home or site runs on a septic tank rather than a public sewer, you need a provider who deals with tanks, disposal and the associated drainage. That is the ground Glancy Enviro’s categories cover, and septic and sewage work follows different rules to a simple blocked pipe, so a firm listing those services explicitly saves you guesswork.
The public rating is 4.9 out of 5 from 621 reviews, the largest review count on this shortlist. A sample that size gives the score real weight, though you should still confirm service area and scope before booking.
- Rating: 4.9/5 (621 Google reviews)
- Address: Clonterm, Longford, N39 H6T0
- Phone: +3531800844060

#6. Gflow Drain Cleaning Dublin | Drain Cleaning & Unblocking Dublin
Gflow Drain Cleaning Dublin works from Cabra East on the North Circular Road in Dublin 7, and the name says what the firm is about: drain cleaning and unblocking in Dublin. That address puts the city centre, Phibsborough and the north inner suburbs within easy reach.
Its listed categories are plumber and sewage disposal service, which suggests a mix of general plumbing and drain-side work. If your issue crosses between indoor pipework and the underground drain, that combination can save you calling two different firms. Ask where the line between their plumbing and drainage work sits when you call.
The public rating is 5 out of 5 from 374 reviews, a strikingly high score on a large sample. Read what reviewers mention most, ask about their coverage across Dublin and compare their first-visit charge with a couple of others.
- Rating: 5/5 (374 Google reviews)
- Address: 44 Blackhorse Grove, N Circular Rd, Cabra East, Dublin 7, D07 X5P0
- Phone: +353852039049

#7. Drain Flow (Drain unblocking/ Cleaning) Cork
Drain Flow is a Cork city drainage firm based in the Cube Building on the Monahan Road in Ballintemple. The location sits close to the city centre and the southside suburbs, handy for jobs on either side of the River Lee. For readers comparing Cork options, the central base is a practical point in the firm’s favour.
The branding is open about the work: drain unblocking and cleaning in Cork. For a straightforward blockage, that single-issue focus is what you want. For anything more complicated, such as repeated blockages or suspected pipe damage, ask at the quoting stage whether they take it on or point you elsewhere.
Their public rating is 5 out of 5 from 21 reviews. The sample is smaller than others on this shortlist, so balance the perfect score against the lower count and read how the most recent comments describe the work.
- Rating: 5/5 (21 Google reviews)
- Address: Cube Building, Monahan Rd, Ballintemple, Cork, T12 H1XY
- Phone: +353870964550

#8. Drain Medic
Drain Medic operates from the Clondalkin Industrial Estate, which puts the firm well placed for Clondalkin, Lucan, Tallaght and the Naas Road corridor. For drainage problems in west Dublin, a local base shortens the wait and keeps travel costs down.
The firm sits in the drainage service category, the standard mix of unblocking, cleaning and investigating drains. A medical-sounding name implies a diagnostic angle, so ask how they trace and confirm the cause of a blockage before any repair work begins.
The public rating is 5 out of 5 from 244 reviews, both a perfect score and a large sample. Treat that as a strong signal and still do the standard checks: get a written quote, ask whether camera inspection is included and confirm the service area before you say yes.
- Rating: 5/5 (244 Google reviews)
- Address: 15.1 Crag Terrace, Clondalkin Industrial Estate, Dublin, D22 AE03
- Phone: +35315059494

#9. VT Drain Service
VT Drain Service is a Cavan town option, based at Lakeview on the Fair Green. A town-centre base suits Cavan town itself and the surrounding villages, with short runs to most of the county.
As a dedicated drainage service, this is the kind of firm you call for blocked drains, slow lines and clean-ups around the house or premises. Smaller towns rarely support many drainage firms, so a dedicated local option is worth knowing about before you need it. Ask how far outside Cavan town they travel and how the call-out charge changes with distance.
Their public rating is 5 out of 5 from 12 reviews, so the score is built on a small sample and should be read that way. Start with a clear description of the symptoms and ask what the first visit costs. A short conversation will tell you quickly whether they are the right fit.
- Rating: 5/5 (12 Google reviews)
- Address: 77 Lakeview, The Fair Green, Cavan, H12 W6H9
- Phone: +353894738117

#10. Independent Drain Testing
Independent Drain Testing is based at Woodberry in Greenfield, on the western side of Cork city near Ballincollig. The name points to testing and diagnosis rather than general call-out work, which can be exactly what a recurring or mysterious drainage problem needs.
A testing-led firm earns its keep when you need evidence: before a repair, ahead of a house purchase or when previous unblocking has not held. Testing also helps where responsibility for a drain is disputed, since a documented report settles arguments. Ask what their testing covers and how the findings feed into any repair or report.
The public rating is 4.9 out of 5 from 23 reviews. Before booking, ask whether testing is the whole job or the first step, and how any repair work is handled once the cause is confirmed.
- Rating: 4.9/5 (23 Google reviews)
- Address: 52 Woodberry, Greenfield, Cork, P31 WP82
- Phone: +353872712672

#11. Maynooth Drains
Maynooth Drains is a hometown option for Maynooth and the surrounding part of north Kildare, based at Mariavilla in the town itself. For local jobs, the short travel distance is a practical advantage. Smaller drainage firms often work from a residential address and run the job from the van, which is normal in this trade.
The firm sits in the standard drainage service category, so treat it as a first call for blockages, slow drains and general drain cleaning around the house or business. A local specialist is also a sensible benchmark quote when you are comparing the larger firms on this shortlist.
The public rating is 5 out of 5 from 64 reviews, a healthy mix of a perfect score and a reasonable sample. Confirm their coverage beyond Maynooth and what the first visit includes before you commit.
- Rating: 5/5 (64 Google reviews)
- Address: The Lawn, Mariavilla, Maynooth, Co. Kildare, W23 R5X5

What to look for in a drainage company
Start with the fit between the firm and the problem. A blocked kitchen drain, a failed septic tank and a collapsed main line are three different jobs, and different companies specialise in each. Check the categories a firm lists, the services described on its own site and whether your job matches what they actually do.
Then look at the evidence you can check. A public rating matters, but the review count matters just as much: a 4.9 built on 600 reviews tells you more than a 5 from 10. Read recent comments for mentions of punctuality, clear quotes and tidy work, and treat a single glowing or angry review as an outlier either way.
How should you compare drainage quotes?
Ask two or three firms for the same thing in writing: the call-out or first-visit charge, what that charge covers, and how additional work is priced. A cheap call-out that excludes camera inspection can cost more overall than a higher fee that includes it.
Clarify the sequence before anyone starts. If a blockage needs a CCTV survey, jetting or excavation, you want to know who decides and at what price. Fix the order in advance: find the cause, agree the fix, then pay for the repair. That keeps you in control of the spend.
Is the drain your responsibility or the utility’s?
In Ireland, drains inside your property boundary that serve only your property are usually your responsibility. The public sewer network is managed by Uisce Éireann, and problems on that side of the line are for them to resolve.
Shared drains and older connections can blur the boundary. Before you pay for a major repair, confirm where the fault sits. A camera survey or a simple location check can show whether the problem is on your side, a neighbour’s or the public network.
Frequently Asked Questions
How much does it cost to unblock a drain in Ireland?
Costs vary with the cause, the access and where you live. Most firms charge a call-out or first-visit fee, then price camera surveys, jetting or repairs separately. Ask for a written breakdown before work starts and compare two or three quotes for the same scope. Be wary of any final price agreed before the cause is found.
Who is responsible for clearing a blocked drain?
Drains within your property boundary that serve only your home are generally your responsibility. The public network is managed by Uisce Éireann. If the problem sits on a shared drain or near the boundary, confirm where it lies before paying. A camera survey or a check with the utility can settle it.
When is a CCTV drain survey worth paying for?
A camera survey earns its keep when blockages keep returning, when you are buying a house, before building over a drain and after flooding. It shows the cause and position of the problem, which makes repair quotes accurate. For a one-off blockage with an obvious cause, you often do not need it.
What should I ask a drainage company before booking?
Ask what the first-visit charge covers, whether camera inspection is included and how extra work is priced. Confirm their service area, how findings are reported and who carries out repairs if a fault is found. Get the answers in writing and compare them with another firm before you commit.
Can I leave a slow drain and deal with it later?
A slow drain rarely fixes itself, and delays narrow your options. Partial blockages can become full ones, and a damaged pipe left alone can worsen. At minimum, note when it started, whether more than one fixture is affected and any smells or gurgling. Those details help a firm diagnose the problem faster.
