Why Choose Fixiz for Your Damp Survey in North London?

Signs You May Need a Damp Survey
- Tide marks or staining on lower walls – a classic sign of rising damp
- Peeling paint or wallpaper – moisture pushing through the wall surface
- White salt deposits (efflorescence) – salts drawn out by moisture movement
- Musty smell – often linked to mould growth behind walls or under floors
- Black mould patches – usually condensation-related but can indicate penetrating damp
- Damp patches on external walls – pointing to defective masonry, pointing, or guttering
- Flagged by a homebuyer survey – requiring specialist investigation before purchase
Types of Damp We Survey and Treat in North London
Rising Damp – Caused by groundwater travelling upward through porous masonry where a damp-proof course is absent, failed, or bridged. Common in pre-1920s North London properties. Penetrating Damp – Water entering through defects in the building fabric: cracked render, failed pointing, blocked gutters, or faulty flat roofs. Condensation & Mould – The most common and frequently misdiagnosed form. Solutions include improved ventilation, thermal insulation, and mould treatment. Basement & Below-Ground Damp – Cellars and lower ground floors are particularly susceptible to hydrostatic water pressure. We design structural waterproofing (tanking) solutions.Areas We Cover for Damp Surveys in North London

Damp Survey North London FAQs
Quick answers to the most common questions.
What does a damp survey involve?
A damp survey involves a thorough visual inspection combined with moisture meter readings across walls, floors, and ceilings. Our surveyor identifies the type of damp present (rising, penetrating, or condensation), locates the source, and provides a written report with recommended remedial works.How long does a damp survey take in North London?
A standard residential damp survey typically takes 1–2 hours on site. A written report is usually provided within 2–3 working days.What is the difference between rising damp, penetrating damp, and condensation?
Rising damp travels upward through walls from ground level and shows as a tide mark with salt deposits. Penetrating damp enters through defects such as failed pointing or cracked render. Condensation — caused by warm moist air on cold surfaces — is the most common form and frequently misdiagnosed as rising damp.Do I need a damp survey before buying a property in North London?
Yes — if a homebuyer survey flags potential damp, a specialist survey is strongly recommended before exchange. It gives you an accurate picture of the problem, the true remediation cost, and leverage for price negotiation.Can you carry out the remediation work after the survey?
