Yes. Damp Solutions surveys and treats rising damp, rain through the wall, and condensation in Greater London. Send the quote form or WhatsApp with the postcode. Basements, lightwells, and pavements above the course are the usual bridge. A lower-ground flat is not diagnosed as a two-storey terrace.

Book a damp survey
Lower-ground floors and solid brick are the usual damp questions in Greater London, not a cavity-wall subsidy job. A mark in a basement is surveyed as below-ground water, and a pavement or lightwell above the damp-proof course is a bridge. Basements, lightwells, and pavements above the course are the usual bridge. A lower-ground flat is not diagnosed as a two-storey terrace.
Split-level houses and mansion blocks often have a room against the earth. That is waterproofing after a survey, not a ground-floor injection.
If the outside ground or a lightwell sits above the course, the wall is wet from the side. The level is lowered or drained before any drilling.
A stain on a shared wall is traced to a neighbour’s gutter, a chimney, or raised ground, not assumed to be rising damp.
Basements, lightwells, and pavements above the course are the usual bridge. A lower-ground flat is not diagnosed as a two-storey terrace. In Greater London the first measurement is the outside level against the damp-proof course. Raised gardens, patio doors, and lightwells bridge a course that is still sound.
Send the Greater London postcode and a photo of the mark. The survey date depends on access and the diary.
Every single job we complete is backed by a solid, long-term guarantee, giving you complete peace of mind that the damp is truly gone for good.
Solid brick party walls hold salts once groundwater has risen. Ordinary gypsum over that plaster fails, so replastering is its own line on the quote.
A wet lower-ground room is quoted as basement work when the wall is retaining earth. A chemical course in the brick above it does not hold back that water.
Winter mould on a cold external wall in a flat is condensation. Trickle vents painted shut and clothes dried indoors are checked before anyone sells a damp-proof course.
Joist ends built into a damp party wall are opened only where the timber is soft. The wall is dried or isolated. Timber is not sprayed and left in the wet.
The written quote for a Greater London house lists metres of wall, salty plaster, and any basement or bridge. The 30-year guarantee covers the treatment those lines name.
We complete every project with thorough quality checks and comprehensive guarantees.






We begin every project by conducting thorough damp surveys using professional moisture meters and thermal imaging.
We begin every project by conducting thorough damp surveys using professional moisture meters and thermal imaging.
We photograph the wall, check the property, cover nearby items, and get the tools ready.
Using proven damp proofing methods and industry-leading materials, we implement targeted treatments specific to your moisture problem.
Covers come off, the repair is checked again, the area is left to dry, and the waste is cleared.
Missed spots are checked, the wall is sound, a finish coating goes on, and you get care tips.

Yes. Damp Solutions surveys and treats rising damp, rain through the wall, and condensation in Greater London. Send the quote form or WhatsApp with the postcode. Basements, lightwells, and pavements above the course are the usual bridge. A lower-ground flat is not diagnosed as a two-storey terrace.
No. A room below the pavement is holding back earth. Rising damp is groundwater creeping up a wall that is mostly above ground.
No. If the pavement or a lightwell bridges a sound course, that bridge is the repair.
Groundwater can rise through masonry when the damp-proof course is missing, has failed, or is bridged by soil, a patio, or render. A low wet patch is not automatically rising damp, because a leaking pipe and rain can look the same. Send the quote form or WhatsApp with the floor and the postcode.
The survey checks the course and the outside ground first. A bridge is removed. Where the course itself has failed, a new horizontal barrier is installed and salt-contaminated plaster is replaced. The wall then dries over months, not the same day. Send the quote form or WhatsApp to book the survey.
A failed course keeps feeding salts into the plaster, and joist ends in that wall can soften. That still does not make every low mark rising damp. The survey says whether the wall, a leak, or condensation is the cause. Send the quote form or WhatsApp with a photo.
Black mould on cold walls and glass in winter is usually moist indoor air, not a failed damp-proof course. Heat, ventilation, and less moisture from drying clothes indoors are the useful changes. A new course does not dry the air. Send the quote form or WhatsApp if the mould keeps returning.
The written quote follows the damp type and how far the repair goes. Injection without replastering is a different job from injection with the salty plaster removed. A figure before the survey is not a quote. Send the quote form or WhatsApp with the postcode.
