Damp & Condensation Surveys
Professional Moisture Investigation, Clear Diagnosis & Practical Recommendations
Independent investigation and diagnosis of damp, mould and moisture issues in your home.
Before you spend money on treatment, you need to know exactly what is causing the problem. Our damp surveys are designed to identify exactly what is going on, whether that is condensation, penetrating damp, rising damp or a combination of factors.
We do not guess, and we do not jump to conclusions. Every property is different, and a proper investigation takes time and the right equipment.
We work with homeowners, landlords and managing agents across Manchester and the wider UK.
When Should You Book a Damp Survey?
You should think about booking a professional damp survey if any of this sounds familiar:
- Persistent black mould that keeps coming back
- Someone has told you that you have “rising damp”
- You are buying or selling a property and need peace of mind
- You suspect cavity wall insulation or loft insulation is linked to damp
- A tenant has reported condensation, mould or musty smells
- You want an independent second opinion before paying for remedial work
Our job is to diagnose the cause first, then only recommend remedial work where it is genuinely needed. For Manchester homeowners, we can usually arrange a survey within a few days.
What Our Damp Survey Includes
Every damp and condensation survey follows a structured investigation so nothing important is missed. Typically, this will include:
- Full internal and external visual inspection
- Moisture profiling using professional moisture measurement equipment
- Hygrometer readings and dew point analysis to understand humidity levels
- Surface temperature checks to identify cold spots and thermal bridges
- Ventilation performance assessment in key rooms such as kitchens and bathrooms
- Assessment of insulation and cavity condition where relevant
- Clear identification of condensation, penetrating damp and true rising damp
- A straightforward explanation of what we have found and what it means for you
- Advice on ventilation improvements including extractor upgrades and positive input ventilation (PIV) systems.
Independent Diagnosis – Not Sales Led
We are not a traditional “damp proofing company” that turns up, looks at one wall and recommends the same treatment every time.
Our surveys are focused on understanding:
- Where the moisture is coming from
- What environmental factors are making it worse
- Any issues with the building fabric, pointing or render
- How well your property is ventilated
- Whether insulation or cold bridging is playing a part
Once we know the cause, we talk you through the options. Sometimes that means remedial work. Other times it is simple changes to heating, ventilation or lifestyle that can make a real difference.
