Mould Growth Removal Service‼️

Is your home or rental property affected by mould growth? A specialist mould removal system is designed to eliminate not only visible surface mould but also the hidden mould spores and roots beneath the surface, helping to provide a longer-lasting solution.

Removing mould is essential to protect both your property and the health of its occupants. Left untreated, mould can contribute to respiratory problems, damage building materials, and result in non-compliance with housing standards and regulations.

What Causes Mould Growth?
Mould is most commonly caused by excess moisture, poor ventilation, and insufficient heating. Everyday activities can significantly increase humidity levels within a property, including:
- Cooking
- Showering and bathing
- Drying clothes indoors
- Normal breathing

Common Ventilation Issues
Without good airflow, moisture becomes trapped, leading to condensation and mould growth. Typical causes include:
- Missing or ineffective extractor fans
- Airtight windows with limited ventilation
- Blocked air vents
- Keeping windows and doors closed for extended periods

Preventing Mould from Returning
While our mould removal treatment effectively eradicates existing mould, it is equally important to address the underlying causes. Improving ventilation, managing moisture levels, and maintaining adequate heating are essential steps to prevent mould from reappearing and to ensure a healthier living environment.

Industrial Dehumidifier Used to Accelerate Drying Following Penetrating Damp Caused by a Roofing Defect‼️

An industrial dehumidifier installed to assist with the drying process following a penetrating damp issue caused by a defect in the extension roof.

The roofing defect has now been repaired, eliminating the primary source of water ingress and preventing any further rainwater pe*******on into the property. With the root cause rectified, the focus is now on removing residual moisture that remains within the affected building materials.

Industrial dehumidifiers are designed to extract large volumes of moisture from the air and surrounding materials. By reducing humidity and preventing the localised air from reaching saturation point, they encourage trapped moisture within the plaster, masonry, and other building elements to evaporate more efficiently.

This controlled drying process will help ensure that the affected areas dry thoroughly, reducing the risk of secondary issues such as mould growth, staining, and material deterioration. As the source of the water ingress has been rectified, no further moisture-related problems are anticipated once the drying process is complete!

Salt-Contaminated Chimney Breast & Party Wall repair‼️

A customer contacted us to inspect a damp issue affecting the area beneath their staircase. While the flooring had previously been repaired, ongoing concerns remained regarding moisture and salt contamination within the walls.

Inspection
On inspection, most of the existing plaster had already been removed, revealing signs of a previous repair to the lower section of the wall. We also identified evidence of salt contamination affecting the same chimney breast above the staircase, showing a recurring issue that required a long-term solution.

Our aim was to identify the source of the problem and recommend a repair that would prevent moisture and salt contamination from affecting the new decorative surfaces’s.

Repair:
To provide a durable, long-term solution, the following repair was carried out:
- Removal of all contaminated plaster and render✅
- Installation of a new Damp Proof Course (DPC)✅
- Application of a damp proofing membrane to act as a barrier against both moisture and hygroscopic salts✅

The affected area is now protected against future salt migration and moisture-related damage, providing a suitable substrate for redecoration.

Following completion of the damp proofing treatment, the walls can be replastered or finished using standard dry-lining (dot-and-dab) techniques 24 hours after the repair.

A repair designed to protect the property’s internal decorative finishes and provide long-term peace of mind✅

Improving your indoor air quality creating a healthier living environment‼️

This is an installation of a Positive Input Ventilation system (PIV Unit) to tackle condensation/mould growth.

Installation of a PIV Unit would introduce a better quality of air and in turn controlling condensation and preventing mould growth.

A PIV Unit draws fresh air from outside into the unit in the loft, where the air is filtered and supplied into the home through the ceiling diffuser. The unit pressurises the home, helping to dilute, displace and replace the moist, stale air with fresh, filtered air.

Before installation we ensure that the loft is suitably insulated and is well ventilated.

PIV Unit benefits:
- Help reduce humidity levels, controlling condensation and preventing mould growth
- Removes indoor and outdoor pollutants from the property and improving indoor air quality
- Low energy consumption
- Benefits asthma sufferers

Internal Penetrating Damp Repair – Bedroom Bay Window‼️

A customer initially contacted us regarding persistent black mould growth beneath a bedroom bay window. Following an inspection, we discovered that a built-in wardrobe had restricted airflow to the area, creating conditions perfect for mould growth issues. The wardrobe has been removed to allow for airflow. Several hairline cracks were identified in the external render, along with deteriorated and contaminated black mortar on the internal bay window wall.

The external render cracks were repaired and sealed to prevent further rainwater ingress and protect the external render from further issues. Due to the condition of the internal wall, we recommended removing the contaminated mortar back to the original brickwork and installing a damp proofing membrane to provide long-term protection before boarding and plastering.

Repair:
- Removal of all contaminated and deteriorated mortar from beneath the bay window, exposing the original brickwork✅
- Application of a damp proofing membrane to create a waterproof barrier and protect the new decorative finishes from moisture and contamination✅

The wall will be ready for plastering or standard dry lining dot and dab techniques can be applied 24 hours after the damp proofing treatment.

This repair provides a clean, stable, and protected substrate, helping to prevent future moisture-related issues and ensuring a durable finish long term.

Damp Proofing repair – Mid Terraced Property Lounge‼️

We were contacted by a homeowner following a full property survey they had carried out, which identified elevated moisture levels across all lounge walls. The survey recommended damp-proofing works to protect future decorative finishes from the effects of rising damp and salt contamination.

During our own inspection, we confirmed high moisture readings at the lower sections of the walls. We also noted that parts of the property are built into a hillside, leaving some walls approximately 1–2 feet below external ground level, which can increase moisture levels.

Repair:
- Removal of contaminated plaster and render back to the original stone/brickwork✅
- Installation of a new Damp Proof Course (DPC)✅
- Application of a damp proofing membrane to provide an effective barrier against salt contamination and moisture✅

Following completion of the damp proofing system, the walls will be ready for replastering or can be finished using standard dry-lining (dot and dab) methods after approximately 24 hours.
A long-lasting solution has now been put in place, ensuring the new decorative finishes are protected from moisture-related damage and salt contamination.

Salt Contamination to Party/Joining Wall – Terrace Property‼️

A Customer recently began renovation works and discovered signs of dampness below the staircase area. We were instructed to carry out an inspection and provide recommendations for a long-term solution prior to redecorating.

Following an inspection, we found that the neighbouring chimney breast is positioned directly behind the affected area. After the customer ruled out roof defects and any active water ingress, it became clear that the issue was caused by hygroscopic salt contamination.
Over time, burning of fossil fuels within chimney flues can leave behind sulphate and chloride salts within surrounding masonry. These salts can attract moisture from inside the property, which can result in persistent damp patches and decorative issues internally, even in the absence of an active leak.

Repair:
- Removal of all salt-contaminated plaster and mortar down to the original brick/stonework✅
- Installation of a new Damp Proof Course (DPC) ✅
- Application of a damp proofing membrane to act as a salt and moisture barrier ✅

This repair will provide a long-term solution, preventing further salt contamination and protecting the new decorative finishes.

The treated surface will be ready for plastering, or alternatively standard dry lining dot and dab techniques can be used 24 hours after the damp proofing treatment⏳

Hygroscopic Salt & Moisture Repair – Chimney Breast / Party Wall‼️

We were contacted by a customer experiencing damp patches and salt contamination on their staircase wall, and were asked to provide a long-term solution to protect the new decorative surface from future contamination.

On inspection, we identified the issue on the adjoining party wall, directly in line with the neighbouring chimney breast. This is a common problem in older properties, caused by sulphate and chloride salts that accumulate within chimney breast over many years of burning fossil fuels. These hygroscopic salts attract moisture from the air inside the property, resulting in damp patches, staining and salt efflorescence.

Repair Works Completed
- Removal of all salt-contaminated plaster and mortar ✅
- Installation of a damp proofing membrane to act as a salt and moisture barrier ✅

Wall can be plastered or standard dry lining dot and dab techniques can be used 24 hours after the damp proofing treatment⏳

We also advised the customer to ensure there are no defects within the roof or chimney structure that could allow rainwater ingress into the chimney breast, as this can contribute to ongoing moisture issues.
