Damp survey in Hythe

Hythe homes, and how they get damp

The old town on the hill, around the High Street and up to St Leonard's Church, has ragstone, brick and timber framed buildings, many listed and in a conservation area. Built into the slope, many have rear walls retaining ground and cellars cut into the hillside. Ragstone walls need lime and breathability, and cement repairs are the commonest reason they become damp.

Between the High Street and the sea, Victorian and Edwardian villas and terraces were built as the town grew as a resort. Solid brick and render, with bays and basements in places, exposed to southerly and south westerly weather. Render, bays and roof drainage cause most of their damp.

Palmarsh, West Hythe and the edges of town are mostly later housing on low ground near the canal and the marsh. Condensation, ventilation and the occasional groundwater issue on the lowest ground are the usual findings.

Ground, water and weather in Hythe

The old town stands on the Hythe Beds, which drain well but slope steeply, so water runs quickly downhill against buildings on the slope and springs appear where the sands meet clay. The Royal Military Canal runs along the foot of the hill, and the land between it and the sea is low, with a high water table, merging into Romney Marsh to the west.

Building on the Hythe Beds

The Hythe Beds give the town good building stone and generally well drained ground, but they also make for a steep town where water moves fast. On the hillside streets, the uphill side of every house is effectively a dam. In heavy rain, surface water and near surface water run down the slope and against the wall, and where the house has a cellar or a lower ground floor, the wall below ground takes water from the side.

Springs are a feature too. Where the permeable sands meet less permeable layers, water emerges, sometimes in gardens and sometimes in cellars. A survey on the hill looks at where the water is coming from and whether it can be intercepted before it reaches the building, which is usually cheaper and more effective than anything applied inside.

Down by the canal and towards the marsh, the ground is lower and wetter, and solid floors in some older houses there show seasonal damp from groundwater. That is managed with ventilation, breathable finishes and drainage rather than with a damp proof course in the walls.

What we find most often in Hythe

• Cement pointing and render on ragstone walls in the old town
• Rear walls and cellars retaining the hillside with water arriving sideways
• Springs and surface water on the steep slope reaching uphill walls
• Render, bay and roof drainage faults on seafront villas
• Groundwater and condensation on lower ground near the canal

Around Hythe

The old town on the hill

Ragstone and timber framed buildings, many listed, built into the slope. Lime repairs, lateral water and cellars are the main themes.

The seafront and villas

Victorian and Edwardian houses facing the Channel. Render, bays and roofs cause most damp.

Saltwood, Seabrook and Palmarsh

A village above the town, a seaside strip to the east and newer housing on the low ground. Rainwater, condensation and groundwater respectively.

Telling the kinds of damp apart

Most of the cost of a damp problem comes from treating the wrong one. Water rising from the ground, rain getting in from outside and moisture condensing from the air inside all leave marks on a Hythe wall, and the marks overlap.

The differences are in when and where. Damp that comes and goes with rain points outside. Damp that is worst in a cold snap, behind furniture and in corners, points to condensation. Damp that is constant, rises to a fairly even height and falls off above it, on a wall with no outside fault, is the one that might be rising. The survey records which of these the evidence supports.

Inside and out: the Hythe survey, step by step

Most damp is decided outside the house, so that is where half the visit goes. On a typical Hythe property we check:

• The outside walls first: pointing, render, sills, and how Kentish ragstone has been repaired over the years
• Where the ground sits against the wall, front and back, and whether a patio or flower bed has crept up
• Rainwater: gutters, hoppers, downpipes and where they discharge, ideally after we have seen them in rain
• Damp readings inside on a pattern, with a reference reading from a dry wall for comparison
• Salts, tide marks and blown plaster, which say what the water has been doing for years
• Room conditions: humidity, dew point and the coldest surfaces, for any mould
• Timber in reach: skirtings, joist ends, sub floor and the loft hatch view of the roof

The report, and what you can do with it

You get it in writing within 24 hours. It is built so you can use it, whether you are living in Hythe, letting there or buying there:

• Hand it to two or three contractors and compare prices for the same job
• Put it to a seller or agent during a purchase, with the evidence attached
• Give it to a landlord, managing agent or freeholder as an independent record
• Check a damp proofing quote you already hold against what was actually found
• Keep it with the deeds, so the next survey starts from facts
• Ask us questions about it afterwards, at no extra charge

Buying or letting in Hythe

Buying in Hythe often means an old house on a slope or a villa near the sea. Homebuyer reports commonly flag damp in rear rooms and cellars, which is usually lateral water from the hill, or in seafront rooms, usually rain. An independent survey before exchange establishes which, and what it will take.

Letting in Hythe? Damp and mould in rented homes are a hazard under the Housing Health and Safety Rating System, and social landlords in England now have fixed timescales to investigate and act under Awaab's Law, with the government planning to extend similar duties to private renting. An independent report that separates building defects from condensation is the evidence both landlords and tenants need. See our guide to landlord damp and mould duties.

Booking a survey in Hythe

1. Tell us the postcode and what you have noticed. Photos help but are not needed.
2. We agree a fixed fee and a slot. Nothing changes once agreed, whatever we find.
3. On the day we inspect outside first, then inside, and talk you through what we see before we leave.
4. The report lands in your inbox within 24 hours, ready to share.

Independent means we have no product behind the report. We do not install damp proofing, waterproofing or ventilation, and we take no commission from anyone who does. That is why a Hythe report from us can say "no treatment needed" without anybody losing a sale. See damp proofing in Hythe if you have already been quoted.
