Damp survey in Rochester

Rochester homes, and how they get damp

The historic core along the High Street and around the cathedral includes timber framed buildings refronted in brick, Georgian houses and early Victorian terraces, many listed and almost all in a conservation area. Old walls here were built with lime mortar and plaster and need to dry outwards and inwards. Cement repairs, gypsum plaster and modern paints are what tip many of them into damp, and the answer is usually to undo those carefully rather than add anything new.

Away from the centre, the streets towards Borstal, Delce and St Margaret's are Victorian and Edwardian brick terraces and villas, some with cellars. Front cellars under the pavement or under a bay are common, and they were built as storage that tolerated damp. Turning one into a habitable room changes what is acceptable, and the survey has to start from what the cellar was built to do.

Strood, Frindsbury and Wainscott are largely terraces from the early twentieth century and estates from the 1950s onwards. Their damp tends to be the modern kind: condensation in bathrooms and bedrooms, bridged courses on houses with raised drives, and cavity issues on exposed elevations facing the river.

Ground, water and weather in Rochester

The Medway is tidal at Rochester, and the riverside on both banks is low. The Esplanade and the lower streets of Strood are close to the water and sensitive to tide, rain and river levels together. Up the slopes, the town sits on chalk, which drains quickly but sends water downhill fast in heavy rain. The ragstone in older walls was brought down the Medway from the quarries around Maidstone, and some of the oldest walls in the town are flint and chalk.

What we find most often in Rochester

• Cement repairs and gypsum plaster sealing old lime walls in the historic centre
• Front cellars under bays and pavements being used as rooms they were never built to be
• Riverside dampness and high water tables on the lower ground of Strood and the Esplanade
• Raised drives and patios bridging damp proof courses on twentieth century houses
• Timber decay in the floors and roofs of older listed buildings where moisture has sat for years

Around Rochester

The High Street and cathedral precinct

Listed and conservation area buildings, often shops or offices with flats above. Surveys are non invasive by default and recommendations are written with consent in mind.

Borstal, Delce and St Margaret's

Victorian and Edwardian houses on the slopes, some with cellars. The pattern of damp often follows the slope, with uphill walls retaining ground and downhill walls exposed.

Strood and Frindsbury

Later terraces and post war housing across the river, with riverside streets that sit low. Condensation, drives and occasional groundwater make up most surveys.

Three kinds of damp, three different fixes

Rising damp needs the ground moisture stopped at the base of the wall. Penetrating damp needs the route in closed: a gutter, a joint, a sill, a flashing. Condensation needs less moisture in the air, more air movement and warmer surfaces. In Rochester, as everywhere, these get confused constantly, and a remedy for one does nothing for the others.

That is the case for an independent survey in a sentence. Somebody needs to work out which problem you have before anybody sells you the fix for one of them.

Inside and out: the Rochester survey, step by step

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

• The outside walls first: pointing, render, sills, and how Kentish ragstone and brick 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

What the written report contains

Your report arrives within 24 hours of the visit. A typical one for a Rochester house sets out:

• A plain English summary on the first page: what is wrong, why, and how urgent it is
• Photographs of each defect, with where it is on the building
• The moisture readings, mapped, with what they mean
• The cause of each damp area, and the faults ruled out and why
• What should be done, in priority order, written so any contractor can price it
• What does not need doing, stated as clearly as what does

Buying or letting in Rochester

A period house in Rochester is a long term commitment, and the homebuyer or building survey will often recommend specialist investigation of damp or timber. That recommendation is a prompt to establish facts, not a verdict. An independent survey sets out what is going on, what is historic and what is active, and what a sensible programme of work would involve, so you can negotiate on evidence.

Letting in Rochester? 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 Rochester

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.

We are survey only. DampScan does not inject damp proof courses, tank walls, spray timbers or fit fans, so nothing in a Rochester report is there to create work for us. If you are holding a damp proofing quote, read damp proofing in Rochester: survey first before you sign it.
