Damp Proofing Specialist
Why London owners and landlords book our repair crew
• Repair-first mindset. Investigation means little without a fix. We remove faulty render, rebuild damp courses, install modern barriers, and repaint with breathable finishes.
• Flexible scheduling. Surveys happen around family life or tenant routines. Work crews arrive once gear is ready, so drying time starts on day one.
• Transparent cost tool. Use our online calculator for a fast estimate, then review a line-by-line quote that matches site findings.
• Long warranties. Chemical courses, cavity membranes, and breathable renders come with insurance-backed cover up to thirty years.
• Ongoing care plan. Three follow-up visits at three, six, and twelve months confirm the fabric stays dry and salt-free.
Our promise is simple. We fix the root issue, prove the result, and stand by the work.
What the Damp Proofing Specialist survey and repair covers
Exterior fabric
Gutters are cleared and resealed. Downpipes are extended to correct outlets. Brick pointing is raked and repointed with lime mortar to help walls breathe. Render cracks are repaired with mesh reinforcement and finished with silicate paint that keeps rain out and vapour moving freely.
Rising damp barrier
Holes are drilled along the lowest mortar joint and filled with silane cream that cures into a water-repellent layer. Where bricks crumble, a physical damp membrane is slotted in, followed by a tidy brick rebuild.
Internal plaster restoration
Damaged gypsum is removed one metre above the tide mark. Walls receive salt resistant base coat and breathable finish plaster. Skirting boards are replaced with pre treated timber primed on all sides before refit.
Basement and cellar systems
Coal vaults and half-sunk kitchens in many Edwardian homes suffer from lateral damp. We line walls with studded cavity membrane, add floor channels, and install a low-energy pump to discharge seepage. Floors gain insulation and a vapour barrier so the space converts from store to snug.
Roof and loft ventilation
Missing tiles and torn felt let rain track down rafters. We replace slips, fit eaves trays, and add ridge vents so warm air leaves before condensation forms. Insulation is lifted clear of eaves to stop frost build-up.
Pipework and bathroom checks
Supply lines are pressure tested, waste traps receive dye tests, and all joints are resealed. Extractor fans switch to humidity-sensing models that clear steam in minutes without manual buttons.
Ventilation and air quality audit
Tracer gas sensors measure air changes in bedrooms and lounges. If readings fall below recommended levels, we recommend trickle vent cleaning or installing mechanical extract units with heat recovery so comfort and dry walls go hand in hand.
Buildings we return to comfort every week
• Victorian terraces in Brixton where raised patio slabs push water above the damp course
• Edwardian semis in Peckham with bay window bricks flaking after decades of wind-driven rain
• Thirties concrete flats in Islington that trap condensation behind cold slabs
• Loft conversions in Walthamstow with winter roof frost dripping into attic rooms
• Modern riverside apartments in Greenwich facing mould behind high-performance insulation
Old or new, moisture follows simple physics. Our job is to redirect it.
