Booking a CCTV Drain Survey Before Buying a Dublin Home

Why a CCTV Drain Survey Before Buying Makes Sense

A CCTV drain survey before buying a home in Dublin shows the condition of the underground pipes that a standard building survey cannot see. A camera is passed through the drains to record cracks, root ingress, displaced joints, collapses and blockages, so you know about repair costs before you sign the contract rather than after you move in.

Below we explain what the survey covers, why it matters for older and newer Dublin homes alike, how to arrange one during the sale, what the findings mean and how to use the report when you negotiate.

What a Standard House Survey Leaves Out

Most buyers in Dublin and Kildare commission a building or engineer's survey once their offer is accepted. That survey is valuable, but it is a visual inspection of what can be seen and reached. The surveyor will lift a manhole cover if one is accessible, look at the gullies and note any obvious smells or standing water. They do not normally put a camera into the pipes.

The drains that carry waste from the kitchen, bathrooms and toilets run underground to the public sewer, often under the driveway, the garden or the extension. A pipe can be cracked, sagging or partly collapsed and still flow well enough on the day of a viewing. The problem only shows itself months later as a blockage, a bad smell, damp in a wall or a sinking patch in the patio.

Responsibility is also worth understanding. The Environmental Protection Agency notes that the property owner or management company is responsible for clearing drains and sewers on private property. Once the sale closes, any fault in the private pipework is yours to put right.

What a Pre-Purchase Drain Survey Can Find

During a CCTV drain survey we pass a waterproof camera through the pipes from the manholes, gullies or access points. The engineer watches the live picture, notes the distance along the run and records the condition of each section. The most common faults we look for are listed below.

• Cracks and fractures in older clay or concrete pipes, which let water leak out and soil wash in.
• Displaced or open joints , where ground movement has pushed one pipe section out of line with the next.
• Root ingress from trees and hedges, where fine roots enter through joints and grow into a mat that catches debris.
• Partial or full collapses , often under driveways or where heavy vehicles have crossed the line.
• Sags or bellies in the pipe, where water sits instead of draining away and solids settle.
• Scale, fat and debris build-up that narrows the bore and points to poor maintenance.
• Poor connections and alterations , such as an extension or utility room tied into the drain in a way that restricts flow.

Some of these are minor and can be dealt with by cleaning. Others need a repair, a liner or excavation. Our earlier article on what a CCTV drain survey actually shows you goes through the footage in more detail.

Homes That Benefit Most From a Homebuyer Drain Survey

Any purchase can justify a survey, but some properties carry more risk. Older terraced and semi-detached houses were often built with clay pipes and mortar or rigid joints, which crack and shift with age and ground movement. Homes with mature trees close to the house or the boundary are more likely to have root problems.

Extensions are another common source of trouble. When a kitchen or bathroom has been added, the original drain may have been built over, rerouted or connected to with a sharp bend. Houses that have stood empty for a long time can also hide problems, because nothing has been flushed through the pipes to show a blockage.

Newer homes are not exempt. Settlement, building debris left in pipes and poorly bedded sections can all show up in the first years. If the vendor mentions past blockages, or you notice slow drains, smells or a gully that overflows, treat that as a strong reason to book the survey.

How to Arrange the Survey During the Sale

Timing matters. The survey is most useful after your offer is accepted and before contracts are signed, when you can still renegotiate or walk away. We suggest following these steps.

1. Ask the estate agent for permission to carry out a drain inspection and confirm who will give access on the day.
2. Find out where the manholes and access points are, as covers are often hidden under gravel, decking or paving.
3. Ask the vendor whether there have been any blockages, repairs or alterations to the drains, and whether any paperwork exists.
4. Book the survey early enough that the report is back before your solicitor needs an answer on the contract.
5. Share the findings with your solicitor and your building surveyor so the drains are considered alongside the rest of the property.

If a pipe is too blocked for the camera to pass, it may need to be cleared first. Tell us when booking if you already know of a problem, so we can plan for it.

Reading the CCTV Drain Survey Report

A useful survey gives you more than a pass or fail. Before booking, ask what you will receive at the end. You want a clear description of each pipe run, where any defect sits along it, how serious it is and what we would recommend doing about it.

Faults generally fall into three groups. Light debris, scale or minor root growth can usually be dealt with by cleaning or high-pressure water jetting. Cracks and open joints in an otherwise sound pipe are often suited to no-dig drain repairs such as patch repairs or relining, which avoid digging up the garden or driveway. A collapsed or badly deformed section may need excavation and replacement.

The type of repair has a big effect on cost and disruption. For a fuller comparison, see our guide to drain excavation versus no-dig repair.

Using the Findings in Your Negotiations

If the survey comes back clear, you have peace of mind and a record of the pipes' condition on the day you bought. That record is useful later if a problem appears and you need to know whether it is new.

If faults are found, you have options. You can ask for a written quote for the repair and use it to agree a lower price, ask the vendor to carry out the work before completion, or decide that the property is not right for you. Your solicitor can advise on the best way to handle this within the sale.

Whatever you decide, the decision is based on facts rather than guesswork. That is the main value of a CCTV drain survey before buying a home.
