Ask which specific biocide they use. Common options include quaternary ammonium compounds or hydrogen peroxide. Avoid products with strong chlorine bleach if you have sensitive skin or pets. Check the Safety Data Sheet online. The chemical must penetrate porous materials like wood and brick. Surface-only sprays miss deep-rooted colonies. Request a product certificate.
Proper cleaning precedes any spray application. The technician should remove loose paint or wallpaper. They must scrub affected areas with a rigid brush. Surfaces must dry completely, usually taking 24 to 48 hours. Applying biocide on damp plaster traps moisture inside. This creates darker stains later. Insist on visible drying time before the next step.
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.
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.
Request proof of trade licensing for damp specialists. Unlicensed workers may use harmful chemicals. Check for liability insurance covering $1 million or more. Verify they handle waste disposal legally. Ask for references from similar homes. This protects you if the treatment fails or damages your property structure.
Carpets and curtains trap mould spores. Ask how the vendor handles soft furnishings. Steam cleaning at 150 degrees Celsius kills most spores. Laundered items need high-temperature cycles. Items cannot be saved if heavily saturated. Replace porous materials that remain damp after 48 hours of drying attempts.
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.
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.
Standard antifungal sprays only kill visible mould. Ask for long-term protective coatings. These bind to walls and resist regrowth. Look for products labeled for high-humidity zones. Application usually requires 3 thin coats. Each coat needs 24 hours to cure fully before the next layer goes on.
Damp often travels up from the ground. Inspect floor drains and external grading. Water pooling near foundations feeds damp into basements. Grade the soil away from the house. Ensure downspouts extend at least 1 meter from the wall. This simple fix prevents recurring moisture issues in living spaces.
