A Complete Approach to Property Moisture Problems
Effective damp proofing requires more than treating the surface of an affected wall. The position of the damage, the age of the building, external ground levels, ventilation and recent weather conditions can all provide important information about how moisture has developed.
Apollo Damp Proofing Ltd considers the complete property before recommending remedial work. Our assessment may include checking internal walls and finishes, inspecting external elevations, reviewing ventilation and identifying defects around roofs, gutters, windows or drainage systems.
Once we understand the likely cause, we can recommend a targeted treatment programme. This avoids relying on temporary cosmetic improvements and helps protect the property against recurring damp, mould and decorative damage.

Damp Surveys for an Accurate Diagnosis
A professional inspection can help distinguish between different forms of damp and prevent an incorrect treatment from being applied. Moisture meters and visible readings can form part of an assessment, but they must be considered alongside the construction and overall condition of the property.
Our damp surveys investigate where the moisture is appearing, how far it has spread and which defects may be contributing to it. We may inspect plaster, floors, walls, skirting boards, windows, ventilation points and accessible external areas.
Following the inspection, we provide practical recommendations based on the findings. Treatment could include installing a damp-proof course, repairing water entry points, replacing damaged plaster or improving airflow. Where no major damp-proofing work is needed, we will explain the maintenance or ventilation measures that may be more appropriate.

Treating Moisture Rising Through Ground-Floor Walls
Rising damp is associated with ground moisture travelling upwards through porous masonry. An effective damp-proof course should restrict this movement, but a problem can develop where the original barrier is missing, deteriorated or bridged by high ground levels, plaster or other materials.
The resulting damage is generally concentrated around the lower part of a wall. Paint and wallpaper may lift, plaster may become weak and powdery, and salts can sometimes appear as moisture evaporates. Timber skirting boards positioned against the damp surface may also deteriorate.
Our rising damp specialists assess whether rising moisture is the probable cause before proposing treatment. Where required, a specialist damp-proof course can be introduced and damaged wall finishes can be addressed using an appropriate specification.

Damp Proofing for Landlords and Commercial Premises
Landlords have a responsibility to respond appropriately when tenants report damp or mould. The source should be investigated rather than automatically being attributed to the way the occupant uses the property. Government guidance emphasises the importance of identifying and addressing the underlying cause of damp and mould.
Apollo Damp Proofing Ltd can inspect rental properties and provide recommendations based on the building’s condition. We also assist commercial property owners where damp is affecting working areas, customer spaces, storage rooms or decorative finishes.

Frequently Asked Questions
Yes. A survey is important because several defects can produce similar marks on a wall. Moisture near floor level is not always rising damp, while black mould is not necessarily caused solely by poor ventilation. Plumbing leaks, external ground levels, defective rainwater systems and damaged wall surfaces can all contribute to a problem. Arranging an inspection allows the affected areas and surrounding building to be assessed before treatment is selected. Apollo Damp Proofing Ltd will explain the likely source and recommend work based on the findings. This reduces the risk of unnecessary expenditure and provides a clearer plan for controlling the moisture and repairing damaged finishes.
Rising damp is often associated with older buildings that were constructed before damp-proof courses became standard, but it can also affect newer properties. A modern damp-proof course may be bridged by raised external ground, internal plaster, debris within a cavity or later alterations. Damage to the barrier or poor detailing around an extension can also allow moisture to bypass it. An inspection is therefore required regardless of the building’s age. We assess the pattern of moisture, condition of the wall and surrounding construction before determining whether rising damp is present. Other possible sources, including leaks and penetrating moisture, are considered during the diagnosis.
Decorative products may hide staining temporarily, but they will not usually stop moisture entering or forming within the wall. Paint may blister or peel again, while wallpaper can trap moisture and conceal further deterioration. The source should first be identified and controlled. Depending on the problem, this could require repairs to the building exterior, a damp-proof course, improved ventilation or another targeted treatment. The wall should then be given suitable time to dry before final decorations are applied. Apollo Damp Proofing Ltd can advise on the correct sequence following a survey. Treating the cause before redecorating gives the finish a much better chance of remaining in good condition.
Yes. Black mould around windows, ceilings and external corners is commonly associated with condensation, although leaks and building defects should also be ruled out. We assess the room’s ventilation, humidity, heating and airflow alongside the position of the mould. Simply cleaning the surface may not prevent it from returning when excess moisture remains within the room. Recommendations may include improving extractor fans, introducing background ventilation, allowing air to circulate behind furniture or addressing cold surfaces. Apollo Damp Proofing Ltd provides tailored condensation solutions rather than applying one standard recommendation to every property. The objective is to reduce the conditions that allow repeated moisture and mould development.
Our services include detailed property damp surveys, rising damp treatment, penetrating damp repairs and condensation and ventilation solutions. The correct service will depend on where moisture is coming from and how it is affecting the building. Some properties may require a combination of work, such as external repairs followed by internal plaster treatment or improved ventilation alongside mould prevention. Our team will inspect the problem and explain which services are relevant rather than recommending every available treatment. This produces a clearer and more proportionate plan for the property.
