Leak Detection & Moisture Assessment

Choose the Right Inspection for Your Property

We identify the root cause of mold, moisture and persistent odors first—so we can recommend the most effective, long-lasting solution.

Free Intake Assessment Free

For more complex projects or properties located near our base, we offer free on-site intake assessments. For simpler cases or properties further away, we typically begin with a remote intake using photos and videos—so we can quickly provide a reliable price indication.

  • Professional on-site assessment (or remote intake where applicable)
  • Moisture readings to identify surface-level problems
  • Practical advice on next steps and treatment options
  • Transparent pricing — quote provided immediately or within 24 hours

Ideal for: Homeowners and businesses seeking an expert opinion on visible mold or initial moisture concerns.

Advanced Infrared Moisture Inspection from €195 excl. VAT

For deeper insight and complete peace of mind: a professional-grade moisture meter and infrared thermal imaging camera detect hidden moisture behind walls, ceilings, floors, and structural elements—often before damage becomes visible.

  • Infrared thermal imaging to locate hidden moisture and cold bridges
  • Targeted moisture measurements for confirmation
  • Comprehensive inspection report with photos, findings, and expert recommendations
  • Clear guidance on prevention and remediation

Ideal for: Property owners who suspect hidden moisture, experience recurring mold or odors, or require documentation for insurance, renovation, or property transactions.

Odor Control, Sanitization & Disinfection

Odors Don’t Just “Fade” — We Remove Them at the Source

Smoke, mold, sewage, pet and food odors soak into wood, concrete, textiles and ventilation. Professional dry and wet fogging neutralizes them at the source and disinfects the whole space.

Odor remediation that targets the root cause

The ultra-fine fog penetrates deep into cracks, structural gaps, crawl spaces, partitions, and ventilation systems—reaching the hidden areas where odors often remain trapped. Highly effective after:

  • Smoke & fire damage
  • Mold-related odors
  • Sewage or moisture incidents
  • Pet odors & organic waste
  • “Stale building” spaces
  • Rental turnover / move-outs
Full-space sanitization & disinfection

Our fogging method treats airborne contamination and surface contamination (including fabrics and porous materials), applied using certified fogging equipment and strict safety protocols. Ideal after:

  • Illness outbreaks
  • Water incidents
  • Tenant turnover
  • Hospitality deep cleans
  • Suspected indoor contamination
  • Poor indoor air quality complaints
Dry Fogging

Best for stubborn odors in materials and hidden spaces. Designed for high penetration where odors have “soaked in”.

Wet Fogging

Used when clients want an additional layer of sanitization and/or a gentle, clean scent finish after odor neutralisation.

The FreshGuard Odor & Disinfection Process
  1. Assessment & Preparation We identify the likely odor source and prepare the space.
  2. Fogging Treatment (Dry or Wet) A fine disinfecting fog is dispersed evenly through the environment to reach surfaces and airspace.
  3. Ventilation & Aftercare The space is ventilated according to safety protocols and returned fresh and hygienically reset.

Safe, professional and residue-conscious. Treatments are restricted to professional use, carried out with appropriate PPE and safety controls, under strict ventilation and re-entry rules.

Mold Removal & Long-Term Prevention

Thorough Mold Removal & Long-Term Protection

Mold isn’t just a surface problem. Advanced removal combined with dry fogging restores clean, healthy air and helps prevent future growth.

Visible mold and hidden spores

We eliminate both visible mold and hidden microscopic spores—including those in hard-to-reach areas like window and door ventilation vents. For severe contamination, remediation may require removal of affected materials such as drywall, insulation, flooring, and furniture. We maintain a controlled, well-ventilated environment throughout, outline a step-by-step plan, and measure airborne particles to ensure your environment is truly clean and safe.

Why removing visible mold isn’t enough

Even after thorough cleaning, thousands of microscopic spores can remain suspended in the air—ready to spread again. Our dry fogging kills the root system of the mold (hyphae), providing an ongoing barrier against further growth, and also kills harmful bacteria, viruses, and fungi.

Our process — safe to use again within hours
  1. Inspection & Preparation We carry out a thorough inspection and protect furniture and surfaces.
  2. Dry Fogging Treatment A dry, antimicrobial mist is evenly dispersed throughout the space—leaving no moisture or residue behind.
  3. Ventilation & Aftercare After treatment, the space is ventilated properly and we check that the air quality has been fully restored.
When is dry fogging the best choice?
  • After mold removal — to eliminate any remaining airborne spores
  • After illness, flooding, or water damage — for full-space disinfection
  • In rental properties, offices, or older buildings
  • In basements, attics, or crawlspaces — where ventilation is limited
  • With allergies or respiratory issues — even if no visible mold is present
Frequently asked questions
Is dry fogging safe for pets and plants?
Yes, once the space has been properly ventilated. We only use biocides approved under EU regulations.
How long does a treatment take?
Usually between 1 and 3 hours, followed by brief ventilation.
Does the product have a strong smell?
Only a mild, fresh scent that fades after a few hours.
Do I need to remove furniture?
No. The fine mist reaches all surfaces without causing damage.

FreshGuard uses only products listed under Article 95 of the ECHA list, fully compliant with the EU Biocidal Products Regulation (BPR, Regulation (EU) No. 528/2012).

Ventilation & Humidity Control

Fresh Air Flow That Keeps Moisture and Mold Away

Without proper ventilation, excess humidity can lead to mold growth, musty odors, poor air quality, and even structural damage. The right ventilation system keeps your space fresh, safe, and comfortable for years to come.

Ventilation installation & replacement

A healthy home starts with clean air and good ventilation. In a recent project, persistent mold and poor air quality in a bedroom were traced to an old, unmaintained unit with ducts full of dust and visible mold—the system had become part of the problem. Within hours of replacing it, the room felt fresher and lighter.

  1. Remove the old unit and ducting, safely disposing of contaminated parts.
  2. Clean the surrounding area to eliminate residual dust and mold.
  3. Install a new, modern system—energy-efficient, quiet and powerful enough for proper air circulation.
  4. Test for optimal airflow and proper extraction of moisture.
Why ventilation matters

Without good ventilation, even the best mold removal is a temporary solution. Proper airflow helps to:

  • Remove excess moisture from the air
  • Prevent condensation on walls and windows
  • Keep air fresh and healthy, especially in bedrooms and living areas
  • Reduce the build-up of dust, allergens, and airborne pollutants
Signs of poor ventilation
  • Condensation on windows
  • Musty odors
  • Mold on walls or ceilings
  • Peeling paint or wallpaper
  • Uneven temperatures
  • Fatigue & headaches from stale air
Humidity control ideal 30–50%

We balance indoor humidity with mechanical ventilation, exhaust fans that vent outside, and properly sized dehumidifiers for basements and crawlspaces—preventing mold, protecting your property and improving comfort.

Complete, honest solutions. When we recommend a ventilation upgrade, it is not about selling an extra service—without proper airflow, moisture and mold problems return.
