Moisture Control
Damp issues can significantly damage the fabric of the building and create health risks. Our specialists identify and treat all types of dampness, from rising ground water to condensation problems, restoring healthy environments in residential and commercial properties.
Understanding Damp Types
Damp problems manifest in various ways, each requiring specific treatment approaches:
- Rising Damp – Moisture traveling upward from ground level, often identifiable by tide mark staining
- Penetrating Damp – Water ingress through walls, typically caused by structural problems or defective building materials
- Condensation – Build-up of moisture when warm, moist air contacts a cold surface
- Basement Damp – Specialised issues affecting below-ground spaces with high groundwater pressure
- Black Mould – A Type of fungus growth resulting from excess moisture and poor ventilation
New Innovative Products
At Renlon, we’re constantly developing better solutions for our clients and the properties that we work on. Our innovation has led to the creation of proprietary products that offer significant advantages over traditional methods.
RenStrength is our revolutionary waterproofing system that eliminates the need to remove existing renders. This breakthrough technology applies directly over failed waterproofing systems, significantly reducing project timelines and disruption.
We are also excited to introduce RenTherme…
Professional Diagnosis and Solutions
The first step in effective damp treatment is a thorough damp survey by our qualified surveyors. We assess moisture levels throughout the property and identify the source of the problem.
Failed damp proof course, damaged cavity walls, or defective wall insulation can allow ground water to penetrate the structure of a building.
Daily activities produce a lot of moisture, and without adequate ventilation, this moist air contacts cold surfaces, particularly during winter months, creating condensation and potentially black mould growth.
Internal leaks, roof defects, and external water ingress can create localised damp issues that spread to the rest of the house.
Our approach complies with building regulations and property care best practices to address both the cause and effects of dampness.

FAQs
Here are some common questions about damp problems. If you need specific advice, please contact us.
Contact UsDifferent types of dampness present distinct patterns. Rising damp typically affects walls up to 1 meter from ground level with visible tide marks.
Penetrating damp shows as isolated damp patches that worsen in wet weather.
Condensation often appears on windows and cold walls, and often with black spot mould.
A professional damp survey provides definitive identification.
Yes, persistent dampness and associated mould growth can cause or exacerbate respiratory symptoms, allergies, and poor indoor air quality. The presence of moisture can also lead to related problems like dry rot in timber and black mould fungus.
Addressing damp issues promptly is essential for the building and occupants health.
While older buildings are more susceptible due to the absence of modern damp-proofing measures, age itself doesn't guarantee damp issues. Many historic properties remain dry with proper maintenance.
Conversely, modern buildings can develop damp problems due to construction defects, lack of ventilation, or household activities (like overuse of a tumble dryer) that increase the risk of condensation.
