About Damp & Mould Treatment
Timeline Expectations
Simple surface cleaning takes 1 day. Complex repairs extend to 3 to 5 days. Drying time dominates the schedule. Do not rush the drying phase. If the pro rushes, mould returns. Schedule follow-up visits in 2 weeks. Check for new spots. Keep the timeline realistic. Weather affects outdoor work. Rain delays roof repairs. Plan accordingly.
Air Leak Sealing
Gaps around windows and doors allow humid air inside. Inspect for cracks in window frames or door thresholds. Seal these using expanding foam or silicone putty. This stops condensation on cold surfaces. Ask the technician to point out specific weak spots they found during the initial site assessment.
Roof Flashing Inspection
Check metal flashing around chimneys and vents. Corroded or loose flashing lets rainwater enter. This causes hidden damp inside ceilings and top-floor walls. Ask for a camera inspection if the roof is steep. Replace any flashing showing rust or gaps larger than 5mm to stop leaks.
Post-Treatment Maintenance Schedule
Ask for a written maintenance plan. You might need dehumidifiers running for 30 days. Clean vents every 4 weeks. Check for new condensation weekly. Keep bedroom humidity under 60%. Follow these steps strictly. Skipping maintenance lets mould return within 6 months in many humid climates and older buildings.
Protecting Your Belongings
Furniture near treatment zones must move. Ask for plastic sheeting to cover floors and remaining items. Chemical dust can settle on electronics. High-value antiques need individual wrapping. Confirm the pro cleans work surfaces after spraying. Leftover residue on smooth countertops may require polishing. Protect ventilation grilles to prevent chemical entry into ducts.
Painting Solutions
Standard emulsion paint traps moisture. It peels and blisters quickly. Use mould-inhibitor primers on previously affected walls. These contain fungicides that stop spore growth. Apply 2 coats for full coverage. Check the product label for active ingredients. Repainting without primer guarantees failure within 12 months. The cost is lower than replacing entire wall sections.
Warranty Details
Ask for a written guarantee. Standard coverage lasts 6 to 12 months. It covers regrowth from the same source. Read exclusions carefully. Most warranties void if you ignore ventilation advice. Keep records of all cleaning sessions. The pro should document before and after photos. This proves the original scope. If mould returns, contact them within the warranty window immediately.
Humidity Monitoring Logs
Request before-and-after readings from digital hygrometers. Indoor humidity should stay below 60%. If it stays above 70%, condensation risks returning. Ask for a 2-week monitoring report. This confirms the treatment worked. Do not accept verbal guarantees without this written data proving environmental stability.
Plumbing Pressure Testing
Burst pipes inside walls cause slow, hidden damp. Ask the technician to test pipe pressure. A drop in pressure indicates a leak. Use electronic leak detectors to find the exact spot. Repairing the pipe stops the source. Ignoring this means treating the symptom while the pipe keeps feeding water.
Finding the Source
Mould treatment fails if you ignore the water source. Ask the pro to use a thermal camera or moisture meter. They must locate leaks in plumbing, roof gaps, or condensation zones. Check for black spots in corners and ceilings. If the reading exceeds 60% relative humidity, dehumidification is needed before any chemical treatment starts.
