One of the most damaging and common problems found in a property is damp. Not only does it damage the things you can see, such as the decorations and plaster, it also decays hidden timbers that are in contact with the damp masonry. Damp is the sole cause of Dry Rot, which causes serious destruction to properties and should be avoided at all cost. Our specialist Property Care Association (PCA) damp and timber surveyor will determine what has caused the damp and what remedial measures are required for our trained operatives to eradicate it. No one wants to have this type of work done but the longer you leave it, the worse it will get and the more it will cost. Your property is probably your biggest investment but if it damp, it is at risk. It is also uneconomical to keep warm until it is dry, so don’t delay, call us free or request a survey now.
IDENTIFYING RISING DAMP: This is the slow upward movement of water from the ground by capillary action. It rises up the wall through porous building materials such as bricks, mortar and plaster. It can cause serious damage to decorations, wall plaster, timber floors and joinery timbers. It also raises humidity and increases the risk of condensation. If you have noticed peeling wall paper at the base of the wall, distorted joinery or damp or damaged wall plaster which is cold to the touch, you probably have Rising Damp. Damp rising from the ground also brings with it hygroscopic salts which, on days of high humidity, attract moisture from the atmosphere and make the walls even more damp.
ERADICATING RISING DAMP: To eradicate rising damp successfully it is important that the damp, contaminated wall plaster is removed. We then pattern drill a chosen line of holes and the base of the wall, clear the holes of dust and inject a blend of Silane/Siloxane cream, damp course, in accordance with our strict procedure. Vertical damp proofing is included as required. The walls are then prepared and re-plastered in accordance with our damp proofing specification, to complete the system. Sound joinery timbers are treated with a high performance timber preservative and refitted or replaced as necessary.
LATERAL DAMP PENETRATION
IDENTIFYING LATERAL DAMP: This is damp that affects the internal surfaces of walls that are built below a higher external ground level or internal concrete floor level. Damp from the wet ground is forced through the wall by hydrostatic pressure and often makes the walls very wet, sometimes black and very cold and wet to the touch, causing considerable and costly internal damage to walls and ceilings that are below or adjacent to high ground levels. Installing a new damp proof course alone, will not prevent lateral damp penetration.
ERADICATING LATERAL DAMP:Lateral Penetrating Damp can only be prevented by installing a structural waterproofing system (Tanking) or high performance damp proof membranes. To carry out our ‘Tanking’ system, first we remove the damp, contaminated wall plaster and thoroughly prepare the walls for treatment. A channel is created to form a floor/wall joint and a scratch coat of our waterproof rendering is applied to the walls. Two slurry coats of our cementitious structural waterproofing system are applied and a floor/wall joint is formed. The walls are the rendered again and plaster set, ready for decorating. Our Cavity Drain Membrane (CDM) system consists of a high a density polyethylene (HDPE) wall and floor membrane, which is fixed in position using waterproof ancillary fixing and jointing materials. This method of damp coursing is ideal for a complete basement or cellar conversion or a new build basement. A CDM system usually incorporates a sump chamber and pump where water behind the membrane is diverted, before being discharged to a suitable place chosen by us. Once installed the completed system can either be dry-lined or plastered directly onto to suit your project.
IDENTIFYING CONDENSATION: Condensation occurs when warm moist air we produce comes into contact with with a cold window or wall surface and condenses. The problem becomes far worse during the winter months when the weather is colder and is often accompanied by Black Spot Mould Fungus, which is not only very damaging to your property and its contents, but also harmful to the health of the people living there.If your windows are misting or running with water, you have water droplets on window sills or walls and black or dark green mould, in the corners of the room, on window reveals or behind items of furniture, these are sure signs you have condensation.
CONTROLLING CONDENSATION:The majority of condensation can be prevented by a change of lifestyles from the occupants, for example, opening windows more often to extract the moist air and keeping the property at a constantly warm temperature, even when you are at work. There may be some rooms of the property that need additional measures which we can install. These can include insulating cold walls or ceilings, installing extractor fans to extract the moist air from kitchens and bathrooms, installing Passive Vapour Vents (PVV’s) which allow draught proof clean air into the room or installing our very economical to run, thermostatically controlled, Condensation Control Unit (CCU). These can be installed either in the loft or on a wall, to suit your property. You will also be advised what you, the occupant could do to reduce condensation.
IDENTIFYING RAIN PENETRATION: This occurs as a result of building defects, such as leaking roofs, leaking rain water goods, defective rendering and brick pointing and various other defects that are due to a lack of regular maintenance.Considerable, sudden damp and staining on the walls or ceilings of any room, especially adjacent to outside walls, chimney breasts or under flat roofs. Appears worse after heavy rainfall.
PREVENTING RAIN PENETRATION:The longer the building defects are left unrepaired the more damage they will cause and the more expensive it will be to repair it. It may be necessary to remove saturated wall plaster and ceilings which will be re-plastered in accordance with our damp proofing specification. All building maintenance defects and internal repairs highlighted in our report can be carried by us, in accordance with good building practice and your insurance companies instructions.
IDENTIFYING WATER DAMAGE: Water damage can be caused by a number of things, the most common being, leaking plumbing, appliances or a leaking roof. Actual flooding from an overflowing river or a burst water main are other causes, but thankfully far less common. The amount of damage will depend on the amount of water and length of time it has been leaking but generally they are first noticed by sudden staining on the walls or ceilings, wet carpets or floors, damaged plaster or collapsed ceiling. Water Damage is often covered by home policy insurance, so call your insurance company now.
DRYING OUT & REPAIRING WATER DAMAGE:The extent of the repair will depend on the location and extent of the damage. First we repair plumbing leaks, pump out a flooded basement or cellar and install industrial dehumidifiers and fans to start the drying process, prior to the restoration work commencing. Saturated plaster and distorted joinery is removed and the walls and ceilings will be re-plastered in accordance with our own damp proof plastering system. The joinery is replaced with new treated timber, to match as closely as possible existing and any damaged fittings will be replaced, prior to us decorating, all in accordance with your insurance companies instructions. We are fully aware of the stress, sudden water damage can cause and it is or aim to get you back to normal as quickly as possible
Whatever the cause, if damp is left unattended, it will get worse and cause more damage. Damp problems should only be dealt with by a specialist company such as Tapco HomeDry, who is a member of the Property Care Association (PCA).
ERADICATING DAMP FROM YOUR PROPERTY
All it takes is one quick phone call to us to arrange for one of our qualified damp and timber surveyors to carry out a thorough survey on your property. This will include taking random surface moisture readings, using a calibrated damp meter, to measure the levels and pattern of the damp so it can correctly identified. These readings will indicate the exact cause of the problem to assist our surveyor in confirming his findings. His diagnosis and recommendations will be issued in our detailed report, together with images and our floor plan. Following your instructions to carry out the work, our experienced and fully trained damp proofing operatives will complete the project to the highest standard, keeping you fully informed at all times. We will protect your property useing only the most up to date methods and safest of materials.
