Are you experiencing penetrating damp in Cornwall?

Penetrating damp typically occurs when water seeps through walls from outside the building. There are two primary causes of penetrating damp. The first is structural defects, which can include issues like damaged roof coverings, cracked brickwork, poorly fitted windows, and malfunctioning guttering and downpipes. The second type is lateral penetrating damp, which arises when the external ground level adjacent to the wall is higher than the internal floor level.

Receive a Complimentary Penetrating Damp Site Survey

Before J R Damp Proofing & Wood Treatments begins any work on your property, a surveyor will conduct an inspection to determine the necessity and scope of the waterproofing system needed. They will also design a customised waterproofing solution tailored to your requirements, ensuring the most cost-effective approach to your damp issue while checking for any decay caused by moisture.

Identify penetrating damp

  • Damaged internal decoration – damp, discoloured tidemarks in line with external ground level on internal surfaces
  • Damaged plaster – blistering, salting and disintegration
  • Rotting skirting boards, floor timbers – wet rot decay
  • Localised dampness – random damp patches at high and low levels that do not dry out
  • Mould growth – musty smell, spoilt decoration
  • Condensation and penetrating damp issues

What Treatments Do You Require?

If your damp issue stems from building defects, we can often handle the repairs. For more extensive work, you can rest assured that we are also qualified in the building trade. We offer two primary solutions for lateral penetrating damp: single membrane and tanking systems. Both options will create a dry internal wall surface, making your cellar or basement rooms usable once again. After the affected area or wall has dried out and there is no damage to the plaster or decay in the timber, you can proceed with redecorating.

What Causes Rising Damp in Your Property?

Rising damp occurs when groundwater is drawn upwards through porous building materials like bricks, mortar, or sandstone. This is a gradual process, and it may take several years for any signs of the problem to become apparent. The rate at which moisture rises through the walls depends on various factors, including the type of wall or floor construction, the characteristics of the ground, and the environmental conditions both inside and outside the building.

Schedule Your Free Rising Damp Survey Today

Given the complex nature of rising damp, identifying it requires a qualified industry surveyor. Our survey will include:

  • External Inspection: We will check for any defects that could be related to the current problem or lead to damp issues in the future.
  • Floorboard Examination: If your ground floor is timber, we may request permission to lift the floorboards to inspect for timber decay affecting the wall plate and joists beneath the surface.
  • Visual Inspection of Internal Ground Floor Walls: We will use a resistance moisture meter to scan all internal ground floor walls. If we detect visible damage to decorations or higher moisture levels in the plaster, a more thorough inspection will follow.
  • Calcium Carbide Tests: These may be conducted to establish a dampness profile, which could involve drilling into the wall to collect mortar samples for on-site testing, subject to the client’s approval.

Spot rising damp in Cornwall

  • Localised dampness – dampness on walls rarely exceeds one metre above ground level, but may go much higher in extreme cases
  • Damaged internal decoration – damp, discoloured “tidemarks” on internal decoration
  • Damaged plaster – blistering, salting and disintegration
  • Rotting skirting boards, floor timbers – wet rot decay

Effective Damp Treatments

Once dampness has been assessed, the surveyor will provide recommendations for treating rising damp, penetrating damp, and basements.

Visit our website to learn more about the signs to watch for, and don’t hesitate to contact us if you have any concerns about the timber in your property in Penzance or anywhere else in Cornwall.

Some key things to look for:

  • Woodworm causes small round holes in your woodwork, similar to the holes in a dart board. Fine, powdery dust around these holes (this is known as frass) and even if you can’t see any holes, you might also find frass escaping from the back or underside of old furniture. Again this suggests active woodworm.
  • Wet rot can be a white or brown rot, which does not refer to the colour of the mould, but the shade that the timber turns when affected. Brown rot will darken the wood, and will break in small cracks, whereas white rot lightens the wood and the damage is visible across the grain.
  • Dry rot is different from wet rot in the sense that it can travel through a building taking its own moisture supply, and can travel between plaster and brick work as well as wood. Dry rot can cause severe damage if it is not treated.

Free Wet and Dry Rot Surveys in Cornwall

Before any treatment begins, our qualified surveyor will perform a detailed inspection of your property. This may involve removing some plaster, skirting boards, or panelling to fully assess the extent of the wet or dry rot and identify its underlying causes.

The Difference Between Wet and Dry Rot

Wet rot is a general term for various fungal species that cause timber decay in damp conditions, leading to significant damage if not addressed. Dry rot, however, occurs when building timbers are exposed to damp, poorly ventilated environments or come into contact with damp masonry. The dry rot fungus (Serpula lacrymans) can cause severe damage and decay to your property if left untreated.

Our surveyor will identify:

  • Check for associated problems such as other types of rot or damp
  • Inspect other areas that may be at risk
  • Provide a cost-effective solution to your problem

Solve Your Wet Rot or Dry Rot Issues in Penzance, Cornwall

Our expert technicians have the skills, craftsmanship, and solutions to eliminate both dry and wet rot. Each property is unique, so various factors must be considered. The key steps in treating dry rot and wet rot include:

  • Identifying and removing the source of moisture sustaining the rot. This may involve repairing defects like damaged or overflowing gutters, missing slates, or blocked air bricks.
  • Ensuring the cause of damp or water ingress is resolved, allowing the timber’s moisture content to drop to a safe level (below 20%).
  • Removing all decayed wood, damaged linings, panelling, skirting boards, ceilings, and plaster to prevent the fungus from spreading further.
  • Eliminating visible and accessible fungal growth.
  • Applying fungicidal treatments to the remaining timber and brickwork to create protective chemical barriers.
  • Replacing all removed timber with preservative-treated wood.

Basement Waterproofing and Tanking Systems in Cornwall

You could have more space than you realise! We offer basement conversions throughout West Cornwall, including full damp proofing and tanking services.

Our comprehensive conversion process begins with an assessment of your existing damp proofing, followed by the installation of any necessary remedial damp courses.

Protect Your Property from Damp with Basement Tanking

Worried your basement is too small to be functional? It could still be useful for storage or even add value to your property for future buyers. Even if you don’t plan to use your basement or cellar, tanking will make it fully waterproof, preventing damp from rising and affecting the upper floors of your home.

What Solutions Are Available for Your Home?

Cement tanking involves applying cement-based waterproof coatings to prevent penetrating damp caused by water moving through earth-retaining walls via capillary action.

These tanking coatings can be plastered over to create a smooth, decorative surface.

Cement tanking is ideal for situations without free-flowing water or flood risk, as well as for small areas with isolated damp issues.

Benefits of cement tanking include:

  • Suitable for small areas and uneven surfaces.
  • No need for a drainage system, sump, or pump.

Solutions and Advice for Condensation Control in Cornwall

We provide a full range of products to help improve air quality in your home. Since we spend most of our time indoors, it’s essential to ensure the air we breathe is clean. We offer effective solutions to control condensation, along with expert advice on maintaining healthy air quality in your property.

Why Does Condensation Occur?

The lack of ventilation caused by improving insulation and double glazing can result in high levels of humid air becoming trapped inside a building, which can become condensation and eventually lead to mould growth.

What Problems Does Condensation Cause in Our Properties in Cornwall?

Condensation is typically a seasonal issue, most noticeable during the colder winter months. It can appear not only on windows but also on cold walls and floors. Occasionally, it can develop in hidden areas, such as roof voids or suspended floors, where timbers may become vulnerable to rot.

Many homes will experience condensation dampness over time, but it becomes problematic when persistent, leading to other tell-tale signs such as:

  • Damp walls with blistering paint
  • Damaged and peeling wallpaper
  • Musty odours
  • Black mould growth

We can supply and install 2020 positive air pressure systems to prevent condensation buildup and address this issue, effectively stopping mould growth and musty smells.

Some Tips for Preventing Condensation

Keeping your windows open for proper ventilation isn’t always practical, especially at night when staying warm is a priority, and it can also pose a security risk. Our recommendations include:

  • When cooking: Cover pans, avoid leaving kettles boiling, and use an extractor fan if possible.
  • Ventilate bathrooms and kitchens: Keep doors closed while these areas are in use.
  • Avoid drying clothes indoors: Don’t place wet clothes on radiators or in front of fires.
  • Maintain a consistent low-level background heating: This helps minimise rapid temperature fluctuations and keeps wall surfaces warm.
