Penetrating damp treatment
Damp that worsens after rain is coming in from somewhere. We find the route: pointing, render, sills, gutters or roof detail; correct it, then repair the wall inside. Free survey, fixed price, no guesswork.

Damp surveys & diagnosis
Find out exactly what is causing the damp, what it takes to fix it, and what it costs, in writing, at a fixed price, with no charge for the visit and no obligation to proceed.

Structural waterproofing & tanking
Below-ground rooms need a waterproofing system, not a coat of damp-seal paint. Membrane and cementitious tanking specified to suit the structure, installed as an approved Sovereign and Wykamol contractor, with a free survey and a fixed price.

Plastering
The replaster is half of any damp repair. We remove contaminated plaster, apply the specified salt-retardant system and leave a flat, decoration-ready finish, as part of a fixed price, by the same contractor that treated the wall.

Rendering
Cracked, hollow or blown render holds water against your masonry. We identify why it failed, repair or renew it with a system suited to the substrate, and fix the damp it was causing inside.

Brickworks & repointing
Open joints and spalled brick faces are the most common route for penetrating damp. We cut out properly, repoint in a mortar matched to your brick, and replace masonry that has broken down.

Brick stitching
Helical stainless bars bonded into the bed joints tie cracked brickwork back into one structure, a repair carried out from the outside, without rebuilding the wall, and finished so the crack disappears.

General building
Damp repairs rarely stop at the damp. We carry out the associated building work: masonry, render, plaster, joinery repairs and making good, so the job finishes with one contractor accountable for all of it.

Small refurbishment & remedial works
Treatment stops the damp; remedial work makes the room liveable again. Plaster, joinery, floors, decoration preparation and making good, completed by the contractor that did the specialist work, at a fixed price.
