How We Fix Downpipe Problems
We start by assessing the downpipe system — checking where water enters at the gutter connection, inspecting the pipe run for visible damage, and testing flow at the outlet. If you’re experiencing overflow, we identify whether it’s a blockage (most common), a damaged pipe section, or poor alignment causing water to back up. For blockages, we clear the pipe using rods or high-pressure water, removing compacted leaves, moss, silt, or debris that’s preventing drainage.
If the downpipe is leaking at joints, we reseal unions, replace worn gaskets, and secure loose brackets. Cracked or split sections are cut out and replaced with new uPVC or cast-iron pipe to match your existing system. Where downpipes are poorly aligned — sloping incorrectly or positioned too far from the wall — we realign and re-bracket them to improve flow and prevent future blockages. We also check the ground-level outlet to ensure water exits safely into a drain, soakaway, or surface channel rather than pooling around your foundation.
After clearing blockages or completing repairs, we water-test the system by pouring water through the gutter to verify proper flow and drainage. If major replacement work is needed (multiple sections, full downpipe runs, or structural issues), we provide a written quote detailing materials, labour, and costs before proceeding. We tidy the site, bag any debris, and leave your property clean. For landlords or property managers, we provide before/after photos and written notes for your records. The goal is simple: water flows from roof to ground safely, without overflow, leaks, or damage to your property. See also our gutter services page for related drainage work.

Frequently Asked Questions
Can blocked downpipes cause internal damp?
Yes, blocked downpipes are a common cause of internal damp. When a downpipe is blocked, water backs up into the gutter and overflows down the external wall. This saturates brickwork and mortar, eventually penetrating through to internal plaster as damp patches, particularly on upper floors near the roofline. The longer water runs down the wall, the worse the damage becomes — leading to mould growth, peeling paint, and rotten window frames. In severe cases, persistent overflow causes water to pool around the foundation, contributing to rising damp in ground-floor rooms. Fixing the blocked downpipe stops the overflow immediately, but you may need time for walls to dry out, and damaged plaster may require repair. Prevention is key: regular gutter cleaning reduces the debris that flows into downpipes and causes blockages. See our roof maintenance page for preventive services.
Do you unblock or replace downpipes?
We do both, depending on what’s needed. For blockages, we unblock downpipes using rods or high-pressure water to clear compacted debris, leaves, silt, or moss. Most blockages can be cleared quickly, restoring proper drainage without needing replacement. However, if the downpipe itself is damaged — cracked, split, corroded, or beyond economical repair — we replace the affected sections or the entire downpipe run if necessary. We use uPVC for most modern replacements (low-maintenance, weather-resistant), or cast-iron for period properties where matching existing materials is important. After unblocking or replacing, we water-test the system to confirm flow is restored. We explain your options honestly — if an unblock will solve the problem, we don’t push for unnecessary replacement. If replacement is the better long-term solution, we explain why and provide a clear written quote before proceeding.
What causes downpipes to block?
Downpipes block when debris from gutters — leaves, moss, silt, roof tile granules — washes into the outlet and compacts inside the pipe. The most common blockage point is at the top where the downpipe connects to the gutter outlet, or in bends and offsets where debris accumulates. Properties surrounded by trees are particularly prone to blockages, especially in autumn when leaves fall. Blocked gutters upstream make the problem worse — if gutters aren’t cleaned regularly, debris builds up and eventually flows into the downpipe during heavy rain, causing a solid blockage. Missing or damaged outlet grilles allow larger debris into the pipe. Poor downpipe alignment — shallow fall or horizontal sections — means debris doesn’t flow freely and sits in the pipe until it compacts. Birds sometimes nest in hopper heads or open-topped downpipes, blocking the entrance. Regular gutter cleaning is the best prevention.
Do you check gutters too?
Yes, we always check the gutter connection when dealing with downpipe problems. A blocked downpipe is often caused by debris flowing from a blocked gutter, so we inspect the gutter outlet and clear any blockages at the junction. If your gutters are full of leaves or silt, we’ll advise that they need cleaning to prevent the downpipe blocking again shortly after we clear it. We also check that gutters have proper fall towards the outlet — if gutters slope incorrectly, water and debris pool rather than flowing to the downpipe, increasing blockage risk. For comprehensive drainage solutions, many customers ask us to clean gutters and clear downpipes together in one visit, which is more efficient and cost-effective than separate call-outs. See our gutter cleaning page for full gutter and downpipe services combined.
Will you provide photos and a written quote?
Yes, we provide photos and written quotes on request. For blockages, we can take photos showing the condition before and after clearing — useful for landlords, property managers, or insurance claims. Photos document the debris removed, the blockage location, and the restored flow after clearing. For repair or replacement work, written quotes detail exactly what’s needed: materials (uPVC, cast-iron), pipe dimensions, labour, access requirements (ladders, scaffolding), and costs broken down clearly. If we identify additional issues during the work — such as damaged brackets, corroded fixings, or problems with the gutter connection — we discuss these with you before proceeding and agree costs upfront. Everything is transparent and documented. For rental properties or portfolio landlords, we structure documentation to suit your record-keeping requirements, including invoicing in your preferred format.
Are you insured for downpipe repair work?
Yes, we carry full public liability insurance for all downpipe and drainage work. Downpipe work involves working at height using ladders or tower access, and occasionally requires scaffolding for upper floors or difficult access. Insurance covers accidental damage to your property, injury to third parties, and our own workforce. You can request to see our insurance documentation at any time. We follow health and safety procedures, use appropriate access equipment, and work carefully to protect your property — covering gardens, patios, and driveways as needed. We’re experienced in working on all types of Dublin properties, from terraced houses to detached homes, flats, and commercial buildings. Professionalism and safety are priorities on every job, whether it’s a simple blockage clearance or a full downpipe replacement across multiple floors. Your property is fully protected while we work.
Can you fix leaking joints and brackets?
Yes, leaking downpipe joints and loose brackets are common repairs we carry out. Joints leak when rubber seals deteriorate, sections separate due to thermal expansion, or unions aren’t properly clipped together. We re-seal joints using appropriate sealants, replace worn gaskets, and ensure all sections are securely connected. Loose brackets — often caused by wall fixings pulling out or brackets corroding — allow the downpipe to move, which can cause joints to separate or crack. We replace damaged brackets, re-fix to solid masonry, and realign the downpipe for proper vertical flow. After repairs, we water-test the system to confirm leaks are fixed and flow is restored. If joints are repeatedly failing or brackets are severely corroded, replacement of that section may be more cost-effective than ongoing repairs. We advise honestly based on the condition of your system and provide options with clear pricing.
Do you offer landlord and property management services?
Yes, we work extensively with landlords and property management companies across Dublin. We understand the specific needs of rental properties — coordinating tenant access (downpipe work is usually external and doesn’t require internal access), providing documentation for maintenance files, working to scheduled maintenance plans, and accommodating invoicing and purchase order systems. For portfolio landlords, we can arrange regular gutter and downpipe maintenance across multiple properties to prevent tenant complaints about overflow or damp. We provide before/after photos, written notes, and invoices structured to your accounting requirements. If tenants report overflow, blocked drains, or damp issues related to downpipes, we attend quickly, assess the problem, and carry out repairs with minimal disruption. We’re tenant-friendly, respectful of occupied properties, and professional in all communications. Many of our clients are letting agents and property managers who rely on us for responsive, reliable drainage work.
