Professional Surveys & Lasting Solutions
Professional Damp Proofing for Long-Term Protection
Our approach is survey-led and evidence-based. Every property is assessed by experienced damp specialists using professional moisture testing, humidity assessment, and detailed visual inspection to identify the cause of damp before any treatment is recommended. All work is completed by our in-house team using proven systems and materials, focused on long-term performance rather than cosmetic fixes.
Our Damp Proofing Process
Every damp issue is different, which is why our work follows a clear, structured process designed to deliver accurate results and long-term protection.
Survey
A comprehensive damp survey is undertaken using moisture profiling, humidity assessment, and detailed inspection of the structure and surroundings, we build a clear picture of how and why moisture is affecting the property.
Diagnosis
Survey findings are carefully analysed to identify the true source of damp within the property. This may include rising ground moisture, external water ingress, internal condensation, or multiple contributing factors acting together.
Treatment
Once the cause is confirmed, appropriate damp proofing works are carried out by our in-house team. Proven systems are selected specifically for the property type, condition, and level of moisture exposure.
Protection
Preventative measures are applied to reduce future risk, including wall reinstatement, ventilation improvements, and external moisture control where required. Treatments are supported by long-term guarantees and aftercare guidance.
What is damp proofing?
Damp proofing is the process of preventing unwanted moisture from entering and remaining within a building. It focuses on walls, floors, and foundations, where moisture can rise through masonry, form through condensation, or enter via external defects.
Unlike full waterproofing, which manages heavy water ingress or flooding, damp proofing addresses the most common moisture problems in UK homes, including rising damp, penetrating damp, and condensation. The goal is to stop moisture at its source, not simply cover visible symptoms.
Effective damp proofing may involve installing physical or chemical barriers, improving ventilation and moisture control, or managing external water through drainage and protective measures. The correct solution depends on how moisture is entering or forming within the property.
Stop the tide marks at source
Rising Damp Treatment
Rising damp occurs when moisture from the ground is drawn up through porous masonry, typically affecting ground floor walls and skirting levels. It is caused by failed, bridged, or missing damp proof courses, often worsened by external ground levels or internal plaster contamination. Quick fixes like repainting, tanking patches, or dehumidifiers fail because they do not stop moisture travelling upward. Proofterior identifies the true moisture path using moisture profiling and salt analysis before installing a targeted damp proof course system. Works usually involve removing contaminated plaster, installing a chemical DPC, applying salt inhibitors, and reinstating breathable finishes. The result is permanently dry walls, protected finishes, and long-term moisture control at source.
Stop the tide marks at source
Penetrating Damp Treatment
Penetrating damp happens when rainwater enters through defects in the external envelope such as cracked render, failed pointing, porous brickwork, or damaged gutters. It occurs because water is allowed to pass horizontally through walls rather than draining away. Temporary sealants or internal coatings fail because water continues to enter from outside. Proofterior traces ingress points using elevation checks, moisture mapping, and external inspections, including high-level assessments where required. Repairs may include masonry restoration, repointing, sealing defects, improving water shedding, and internal drying strategies. The outcome is a weather-tight structure with moisture stopped before it reaches internal surfaces.
Cold Wall and Thermal Damp Issues
Cold wall damp is caused by condensation forming on under-insulated or thermally inefficient walls, often mistaken for leaks or rising damp. It happens when warm indoor air meets cold wall surfaces, allowing moisture to condense repeatedly. Quick fixes like anti-mould paint or increased heating fail because the wall temperature remains unchanged. Proofterior assesses surface temperatures, insulation gaps, ventilation balance, and humidity levels. Solutions may include thermal lining systems, insulation upgrades, vapour control strategies, and ventilation improvements. The result is warmer wall surfaces, reduced condensation risk, and healthier indoor air quality.
Stop chimney staining and internal leaks
Chimney Damp Repairs and Dropping Chimney Stacks
Chimney damp commonly affects breast walls and upper floors due to water ingress, condensation, or trapped moisture in disused flues. It occurs when chimneys are no longer heated or ventilated, or when external defects allow rain entry. Blocking vents or repainting fails because moisture remains trapped inside the stack. Proofterior inspects chimney structure, ventilation, flaunching, and flashing integrity. Works may include capping solutions, vent installation, repointing, lead repairs, and internal damp remediation. The outcome is a dry, ventilated chimney structure with damp staining eliminated and future moisture prevented.0.
Redirect surface water away from your walls
Channel Drainage
Channel drainage is required when surface water accumulates near walls, thresholds, or below-ground areas, increasing the risk of penetrating damp and internal flooding. Problems arise due to poor ground drainage, high external levels, or ineffective water run-off. Quick fixes like clearing gutters fail if water still pools against the structure. Proofterior designs drainage systems based on site levels, soil conditions, and water flow patterns. Installation typically involves ground excavation, channel placement, correct falls, and discharge integration. The result is controlled water movement away from the building and reduced moisture pressure on walls and foundations.
Create a durable moisture barrier
Waterproof Coatings and Tanking
Waterproof coatings and tanking systems are used where walls are exposed to persistent moisture pressure, particularly in basements or retaining walls. Damp occurs when groundwater or saturated masonry pushes moisture inward. Local patching or paint-on sealers fail under sustained pressure. Proofterior assesses hydrostatic risk and substrate condition before specifying appropriate tanking or coating systems. Works involve surface preparation, full system application, detailing joints and penetrations, and controlled reinstatement. The outcome is a sealed internal environment protected against ongoing water ingress.
Find the real source fast
Leak Prevention and Diagnosis
Leaks often present as unexplained damp patches, staining, or persistent moisture unrelated to weather or condensation. They occur due to failed pipework, drainage defects, or concealed plumbing issues. Guesswork repairs fail because the source is not properly identified. Proofterior uses targeted inspections, moisture tracing, and where necessary CCTV drain surveys to locate faults accurately. Repairs are then focused directly on the source, avoiding unnecessary disruption. The result is resolved moisture issues, reduced repair costs, and prevention of future structural damage.
Make below-ground spaces reliably dry
Basements and Below-Ground Damp and Water Ingress
Basements are highly vulnerable to damp and water ingress due to surrounding ground moisture and hydrostatic pressure. Problems arise when structures lack adequate waterproofing or drainage systems. Temporary sealants or partial tanking fail when pressure builds elsewhere. Proofterior assesses structural conditions, water pathways, and pressure risks before designing a compliant solution. Works may include tanking systems, cavity drainage membranes, sump pumps, or combined waterproofing strategies. The outcome is a dry, usable below-ground space with controlled moisture management and long-term protection.
