Leak Detection in Mount Roskill
Damp skirting and flooring in a garage can make it difficult to tell where water first entered. The wettest patch may be where moisture collects rather than where a pipe is leaking.

Stately covers Mount Roskill, investigating the affected area and checking possible water paths before recommending access or repairs. Tell us when you first noticed the dampness, whether it changes after rain or water use, and whether the patch is spreading across the garage floor.
What to observe around the damp patch
Look for a darkened skirting edge, swollen flooring, lifting finishes or a damp line along the wall base. Photograph the area from the same position each day if it is safe. These observations help us understand the pattern, but they cannot confirm a leaking pipe by themselves.
Move stored boxes and loose belongings away from the affected wall so the surface is visible. Avoid pulling off skirting or lifting flooring to investigate. If water is near sockets, leads or powered equipment, keep clear of that area and tell us before any inspection begins.
Checking whether plumbing is the source
Onsite, we start with the visible dampness and ask about its timing. We inspect accessible plumbing associated with the garage and consider how water could reach the wall base. Dampness that follows rainfall could point towards water entry, while persistent wetting could justify closer checks of pressurised pipework.
Moisture readings help map the affected area and compare nearby surfaces. Where appropriate, we use pressure checks or acoustic listening to narrow the investigation. Each result needs interpreting alongside the layout and visible signs; a moisture reading alone cannot tell us which concealed fitting or pipe needs repair.

Agreeing on isolation and physical access
Clear access along the garage wall helps us inspect corners, pipe entries and changes in floor finish. Let us know about fixed shelving or stored items that restrict movement. We will explain what needs moving and whether we need access to an adjoining area to follow the suspected route.
If an accessible valve allows useful isolation, we explain which water supply will be interrupted before operating it. Sometimes testing narrows the area but an opening is still needed for confirmation. We discuss the proposed location, likely disruption and permission required before removing finishes or exposing concealed pipework.
Using findings to choose the repair
We explain what the checks support, what remains uncertain and whether the suspected source has been physically confirmed. Water can travel along a wall base or beneath a floor finish, so the repair location may differ from the damp patch. That distinction matters before agreeing to an opening.
Once a damaged pipe or fitting is exposed, its condition and accessibility guide the repair. If checks confirm a leak on the private incoming supply serving the property, water main repairs may be the appropriate next step. If plumbing checks point elsewhere, we explain the findings rather than proposing speculative pipe repairs.
Checking the result and handing over clearly
After an agreed plumbing repair, we restore the supply and check the repaired section for leakage. We also explain which garage surfaces were already damp. Residual moisture can remain after the source is stopped, so immediate dryness is not the only measure of whether the repair has worked.
The handover should separate completed work from any further investigation, drying or reinstatement needed. Keep photographs and note whether the damp boundary shrinks, stays unchanged or grows. Avoid covering the area with stored belongings straight away, and contact us if fresh wetting appears or the patch expands.
Leak detection: questions from Mount Roskill
Can I check the meter before you visit?
Yes. Choose a period with no water use for four hours or more, record readings before and after, and leave the meter tap on. A change can indicate leakage, but it will not locate the source of the garage dampness.
Should I remove the damp skirting?
No. Leave it in place for the initial inspection. Clear loose belongings and take photographs instead. If removal is needed to confirm or reach a leak, we explain the proposed opening before work proceeds.
What should I send when contacting Stately?
Send a wide photograph of the garage wall and floor, a close view of the damp edge, and notes about when it appears. Mention spreading moisture, nearby electrical fittings and any access restrictions.

Thomas was professional, fast and efficient. He explained things clearly, and honestly. We were about to leave for the South Island for the weekend, Thomas made sure the job was completed in good order before we left. He also checked-in with us periodically to ensure there were no further issues.
