Menai Bridge, Ynys Môn
Big Victorian houses,
and the water they face.
Porthaethwy grew when the bridge opened, and it grew handsomely — substantial Victorian and Edwardian villas on sloping ground above the strait. Fine houses, and a set of damp problems that come specifically with that kind of building in that position.
The local stock
What Menai Bridge is built from.
Large houses, cellars, and long roofs
Substantial detached and semi-detached stone houses, many with cellars and complex roofs. Valley gutters, hidden flat junctions behind parapets and long downpipe runs — one blocked outlet can put water into a wall for a year before anyone sees a mark.
Standing water and dry rot
A cellar with poor ventilation, standing water below a leaking downpipe and a timber floor above it is close to ideal conditions for dry rot. It is the one finding worth acting on the same week, and Menai Bridge has the housing stock for it.
Driven rain off the water
Elevations facing the strait take rain straight off open water. Render cracks and junction failures matter far more here than they would inland, and the damage concentrates around cills, reveals and bay heads.
Ground levels above the damp course
Built into a slope, so the ground at the back is often well above the level at the front. Raised rear ground, later patios and retaining walls are a recurring cause of what gets diagnosed as rising damp.
Worth knowing
Pre-purchase, more often than not.
A lot of the work here is for buyers. A Victorian villa with a cellar, a valley gutter and a strait-facing elevation is exactly the kind of house where a homebuyer's report says 'high damp meter readings, obtain a specialist report' and leaves it there.
That sentence has sold a great many injection damp-proof courses that were never needed. An independent survey tells you which of the three or four possible causes it actually is, and what it will cost to put right — before you negotiate, not after.
What you get
The survey itself.
Internal moisture profile
Readings at height intervals across affected walls, so a pattern emerges rather than a single number.
Salt analysis
Hygroscopic salts separate genuine rising damp from a leak or from condensation. It is the test most treatment quotes skip.
External defect inspection
Render, pointing, downpipes, ground levels, slate. The cause is outside far more often than it is in the wall.
Air and surface conditions
Temperature, humidity and surface readings — the evidence that separates a ventilation problem from water ingress.
Independent and insured. We survey; we do not sell treatments, so there is no quote waiting at the end of the report.
