A Feuchtigkeitsgutachten (moisture inspection report) is a specialist building assessment that identifies the source, extent, and severity of damp problems in a property. In Berlin, moisture is one of the most common and costly defects—particularly in Altbau buildings where rising damp (Aufstiegsfeuchte), condensation, and failed waterproofing are widespread. ABC Experts uses FLIR thermal imaging cameras and calibrated moisture meters to pinpoint exactly where moisture is entering the building, how far it has spread, and what remediation is needed—with repair cost estimates delivered in an English PDF report within 48 hours.
Undiagnosed moisture costs tens of thousands in repairs—and affects your health. Mold growth, structural decay, and plaster damage can accelerate if the source isn't found. Altbau buyers especially: get a moisture report before signing.
Our Moisture Inspection Includes
Visual Assessment
Check all rooms, basement, roof space, and exterior for visible moisture, staining, mold, and structural dampness.
Thermal Imaging
FLIR camera identifies cold spots where moisture is accumulating—invisible to the naked eye.
Humidity & Dew Point
Measure relative humidity and surface temperatures to pinpoint condensation risk zones.
Moisture Meter Testing
Non-destructive moisture readings in walls, plaster, and wood to quantify the problem.
Written recommendations and estimated repair costs to fix the problem long-term.
Moisture in Berlin Altbau: What You Need to Know
Berlin's Gründerzeit buildings (1880–1920) are beautiful—but moisture is endemic. Original construction used lime mortar (not cement), had no damp-proof membranes, and relied on natural ventilation. Without central heating in the past, buildings dried out quickly. Today, modern insulation and airtight windows trap moisture.
Rising damp (Aufstiegsfeuchte) is common in basements and ground floors. Water wicks up from the soil through porous masonry. Condensation happens when warm, humid air meets cold surfaces (exterior walls, window frames, bathroom tiles). Roof leaks and gutter failures are the third major culprit.
What's the difference between rising damp and condensation?
Rising damp comes from the ground via porous masonry. Condensation is water vapor in the air that condenses on cold surfaces. Rising damp is a structural problem; condensation is a ventilation/heating issue. Both need fixing.
How much does it cost to fix moisture problems?
Depends on the cause. Condensation: €500–2,000 (better ventilation, insulation). Rising damp: €5,000–20,000+ (damp-proof course, membrane). Roof leaks: €2,000–10,000. We'll estimate during the inspection.
Will moisture damage my Altbau's character?
Not if fixed right. Modern solutions (breathable membranes, lime plaster) preserve historic fabric. We recommend methods that respect the building's original design.
How long does a moisture inspection take?
Quick Check: 30 minutes. Full Analysis: 2–3 hours depending on property size. We'll schedule around your calendar.
