What Is a Damp Survey?

A damp survey specifically identifies the types and causes of damp within a property. It's a thorough examination conducted by an expert, where they'll look for telltale signs such as tide marks on walls, peeling wallpaper, or a musty smell—features that make a damp survey a key tool in protecting your home's integrity.

Is It Worth Getting a Damp Survey?

Yes, it's absolutely worth it. A professional damp survey can save you time and money in the long run by pinpointing the exact issues and allowing for targeted treatments. It's a small investment to protect your property and your health from the risks associated with unchecked damp.

What Are the Benefits of Getting a Damp Survey?

The benefits of getting a professional damp survey are extensive and can have a positive impact on both your property and your well-being:

  • Accurate Identification of Damp: A professional survey provides a precise diagnosis, distinguishing between rising damp, penetrating damp, and condensation issues.
  • Tailored Treatment Plans: With a clear understanding of the damp type, you're able to target the problem with appropriate, effective treatments, saving time and expense on unnecessary or incorrect methods.
  • Prevention of Further Damage: Early detection and treatment can prevent additional damage to your property, saving you from more extensive and costly repairs in the future.
  • Increased Property Value: A home free of damp issues is more attractive to potential buyers or renters, thereby potentially increasing its market value.
  • Health Benefits: By addressing damp quickly, you reduce the risk of mould and mildew, which can cause respiratory issues and exacerbate allergies and asthma.

What Are the Different Types of Damp Treatments?

When tackling damp, knowing your enemy is half the battle. Different types of damp require specific treatments. In this section, we'll discuss the common treatments for rising damp, penetrating damp, condensation control, and more innovative solutions such as damp-proof membranes, tanking, and basement waterproofing systems.

Rising Damp Treatment

Rising damp occurs when groundwater moves up through a wall or floor. It's recognized by damp patches, peeling paint, or wallpaper and a characteristic ‘tide line' of brown staining or salt efflorescence on the wall.

Treatments like a damp-proof course (DPC) injection create a barrier to moisture. Another method, electro-osmotic DPC systems, introduces an electrical charge to repel dampness away from the wall.

Pros:

  • Stops further deterioration of wall materials and plaster.
  • Eliminates the unhealthy conditions that can lead to respiratory issues and allergens.

Cons:

  • Treatment can be disruptive as it often involves chemical injection and replastering.

Penetrating Damp Treatment

Penetrating damp is caused when water from outside enters through the fabric of the building. It can occur at all levels of a building but is more prevalent higher up. It can be identified by damp patches that may darken when it rains.

It’s essential to identify the source of water ingress. Once located, repairs such as resealing windows or replacing damaged roof tiles can be carried out.

Pros:

  • Fixes could be as straightforward as repairing guttering or downpipes, thus relatively inexpensive.
  • Long-term solution when correctly identified and treated, preventing recurring issues.

Cons:

  • Can sometimes involve significant exterior work, such as re-rendering or even roof repairs.

Condensation Control

Condensation is arguably the most common form of damp and manifests when warm, moist air meets cold surfaces, leading to water droplets forming. This often results in mold growth, particularly around windows and on walls.

Improvements in heating and insulation, coupled with adequate ventilation, can help control condensation effectively.

Pros:

  • Simple lifestyle changes, like opening windows or using extractor fans, can reduce condensation.
  • Equipment like dehumidifiers can manage moisture levels with minimal installation hassle.

Cons:

  • Running costs of dehumidifiers and other electric solutions can add up.

Damp-Proof Membranes (DPM)

Damp-proof membranes act as a robust barrier through which moisture can’t pass. They're usually a flexible or semi-rigid sheet of material laid under floors or behind walls.

A DPM is a reliable line of defense but requires expert fitting to ensure it's sealed correctly and performs as intended.

Pros:

  • Long-lasting solution that effectively blocks moisture entry.
  • Can be part of a more extensive damp-proofing strategy or used during new construction for prevention.

Cons:

  • The installation process can be disruptive, often necessitating the removal of existing plaster or flooring.
  • Not always suitable for historical buildings due to the risk of trapping moisture in walls.

Tank Waterproofing

Tanking is the process of making walls and floors in below-ground rooms like cellars or basements watertight. It’s usually accomplished by applying a waterproof cementitious coating or membrane.

Tanking is particularly well-suited to underground rooms where external damp proofing isn't possible.

Pros:

  • Provides a highly effective, impermeable barrier against groundwater.
  • Can increase the usable space in a property by making basements dry and habitable.

Cons:

  • Can be one of the more expensive options due to the labor and materials required.

Basement Waterproofing Systems

These systems are engineered solutions that manage water entry in below-ground spaces through a combination of barriers, drains, and pumps.

For new buildings, incorporating a waterproofing system from the start is easier and more cost-effective than retrofitting one later.

Pros:

  • Offers a comprehensive solution, preventing both damp and structural issues associated with water ingress.
  • A working system increases property value by making basements and cellars fully usable.

Cons:

  • Installation is complex and usually the most expensive option on the market.

Silicone Treatments

Silicone water repellents are applied to the exterior masonry to protect against penetrating damp. They work by lining the pores of the masonry with silicone, preventing water from passing through but allowing moisture from inside to escape.

They are ideal for homes in areas with high exposure to rain and can significantly reduce the risk of penetrating damp.

Pros:

  • Relatively inexpensive and quick to apply compared to other treatments.
  • Can be a proactive measure, preventing damp before it starts.

Cons:

  • It's not a fix for existing damp issues and is better as a preventive measure.
