Detecting drafts or cold bridges in the home: Comfort and energy savings
Drafts and thermal bridges are treacherous energy guzzlers in homes, offices, and commercial buildings in the Netherlands. You feel it immediately: you're sitting at home with cold feet, despite a properly functioning heating system. With our advanced techniques at Ultrices leak detection, we pinpoint this hidden problem with pinpoint accuracy, without the need for any demolition work. We quickly provide insight into where unnecessary heat is being lost, addressing your energy consumption and unpleasant cold spots.How does draft or cold bridge detection work?
Professional detection uses smart, non-invasive methods that immediately uncover the cause of drafts, heat loss, and an unpleasant indoor climate. We utilize advanced equipment such as FLIR thermal imaging cameras, blower door tests, and ultrasonic detection. This allows us to quickly and easily locate the source of unwanted airflows and thermal bridges, from facades to floors and roofs, without demolition.- Thermal imaging camera responds to temperature differences: Infrared images show heat loss, cold bridges and draughts with crystal clarity — even if the problem has been hidden for years.
- Ultrasonic detection captures sound: We accurately map invisible air leaks that cannot be detected with the naked eye using ultrasonic equipment that detects air permeability.
- Blower door test systematically searches for air leaks: By pressurising or overpressurising the building, we locate any opening where uncontrolled airflow occurs.
- Smoke test visibly demonstrates wind and air permeability: Smoke follows every smallest crack and draft, perfect for exposing leaks along window frames or in cavity walls.

Process of detecting drafts or cold bridges
Our approach is step-by-step and efficient, so you know immediately where you stand and, more importantly, where you need to intervene.- Inventory situation: Together we will look at the complaints and pulses where you are experiencing the problems, so that we can take targeted action.
- Inspection with infrared and ultrasonic: We use our thermal camera and ultrasonic detectors directly, so that even hidden thermal bridges are made visible.
- Reporting and advice: Within three days, you'll receive an expert report with photos, findings, and solution-oriented advice. Thanks to our partnership with insurers, reimbursement is often easily arranged.
- Emergency and aftercare: In case of urgent complaints, our specialists can intervene immediately nationwide and, if desired, we will help to resolve the defects.
Leak detection process request
What exactly is a draft or cold bridge?
A thermal bridge occurs when materials like concrete, steel, or cavity wall ties allow the outside temperature to leak into the building. Drafts occur where seams, cracks, or connections aren't properly sealed, for example, in window frames, roofs, or crawl spaces. Throughout Dutch construction history, homes and commercial buildings from the last century are particularly susceptible to thermal bridges. This is often seen in homes with uninsulated walls and outdated window frames, but new construction can also suffer from drafts due to improper connections.- Examples: • Cold floors above crawl spaces without insulation • Draughts through poorly closing windows and doors • Cool spots in insulated facades due to steel anchors
Causes and consequences of cold bridges
Thermal bridges often occur where materials with high thermal conductivity directly transmit the outside temperature. This is detrimental to living comfort and increases the risk of mold and moisture problems. Common culprits include concrete lintels above windows, roof-wall junctions, cavity wall anchors, and thermal bridges in the floor structure. Your energy bill rises unnecessarily, and you're more likely to develop health problems due to an unhealthy indoor climate.- Short-term consequences: • Draft • Cold feet • Uncomfortable rooms
- Long-term: • Higher heating costs • Moisture and mold formation

How exactly does draft or cold bridge detection work?
Draft and thermal bridge detection is performed using advanced techniques such as thermography and smoke testing. At Ultrices Leak Detection, we use thermal cameras and airflow meters to quickly and accurately locate thermal bridges in your home or business premises. Our certified experts analyze where insulation is lacking or where unwanted air is entering. This allows us to address persistent draft problems without the need for extensive demolition work. Thermal inspection visualizes temperature differences in facades, floors, and roofs, while smoke detection reveals airflows at windows, doors, and frames. This way, we deliver clear findings within a day and provide targeted advice for repair. Thanks to our expert report, you'll know exactly where the problem is and what you can do about it. With our fast 24-hour service, we're rolling out this approach nationwide.
What symptoms indicate a draft or cold bridge in the house?
Typical symptoms of drafts or thermal bridges include cold floors, cold walls, condensation on windows, and high heating costs. You often find that the thermostat needs to be turned up constantly to maintain a comfortable level. Sometimes walls or window frames even show damp patches, mold, or a musty smell, which can indicate structural thermal bridges or insulation problems. These problems are particularly common in older homes or poorly insulated new construction. Our experienced specialists recognize these details and select the most suitable detection method.

How quickly can an expert detect and report thermal bridges?
One of our detection specialists will be at your doorstep within an hour, wherever you live in the Netherlands. Using direct techniques like blower door tests and thermal imaging cameras, we usually detect all existing drafts and thermal bridges within a few hours. We combine measurement data, structural inspections, and modern analysis tools for the most comprehensive results possible. Afterward, you'll receive a comprehensive expert report by email within three business days, including measurement results, photos, advice, and a repair plan. At Ultrices leak detection, we always operate on a "no solution, no payment" basis, guaranteed without unnecessary demolition work. This allows you to address drafts and energy loss effectively and quickly.
Is detecting draughts or cold bridges useful for renovation or energy saving?
Absolutely, reliable detection is the smart first step when renovating, making your home more sustainable, or lowering your energy bill. By specifically mapping all points of heat loss, you prevent investments in insulation or draft strips from being partially wasted. After the inspection, you know exactly where sustainability measures yield the highest return. For professionals, such as contractors or energy consultants, our expert report provides independent evidence to clients, insurers, and subsidy agencies. This way, you not only enjoy greater living comfort but can also demonstrate compliance with building quality standards and energy label requirements.
