Every photo here is from a Trident job.

Damp-proofing cream injected into the mortar course of exposed brickwork, by the surveyor who specified it.

Contaminated plaster hacked off and brickwork exposed ready for injection and salt-resistant re-rendering.

Waterproof render applied to the lower walls after treatment, to stop salts coming back through the finish.

Full-height waterproof render on a timber-framed period property, worked around the original beams.

Replastered and ready to decorate. Membrane trimmed at floor level, skirtings to follow.

Rot-damaged floor timbers cut out and renewed with treated joists.

Floor lifted and ground reduced to deal with damp at its source before rebuilding.

Drilling out old bitumen-coated brickwork in a timber-framed building ahead of treatment.

Insulation laid correctly as part of a condensation-control package.

Making good is part of the job: skim finish ready for paint.

Bay window walls hacked back to brick with the floor protected. The damp was diagnosed before a single product went on.

The same bay after treatment: salt-resistant render on, drying and ready for skim and decoration.

Studded floor membrane laid as part of a waterproofing system, managing moisture instead of fighting it.

Waterproof render applied by hand to a prepared wall, mixed on site and worked in coats.

Decayed floor timbers cut out, new treated timber let in.

A new chemical damp-proof course injected along a hallway wall stripped back to brick.

Professional DPC injection equipment set up against a stripped wall.

Plaster hacked back to brick and floor timbers opened up so the cause is found before anything is treated.
