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.
Damp proofing questions
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.
FAQs
Rising damp
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.
Condensation
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.

Drying, DIY, and the wrong repair
A solid brick wall about 230mm thick commonly takes months after the water is stopped. Thicker walls take longer. Vinyl paint too soon traps moisture in the new plaster.
A kit does not show whether the course is bridged, whether the stain is rain, or whether the plaster is full of salts. Those are the reasons an injection fails.
No. High ground, a leaking gutter, and a pipe leak all wet the bottom of a wall. The survey separates them before any drilling.
No. The 30-year guarantee covers the treatment named in the quote. Drying is a separate wait, and it is written into the job.
It is our guarantee on the treatment named in the quote. We do not describe it as an insurance-backed guarantee.
Damp Solutions Checklist
We inspect and photograph, check the property, cover nearby items, and prepare the tools.
We apply the specialist treatment, inject the chemical damp-proofing where that is the method, replaster the treated wall, and protect the surrounding area.
Covers come off, the repair is checked, the area is left to dry, waste is cleared, and the treatment carries a 30-year guarantee.
