Damp reports are probably one of the most common reports for older properties in the South East.  They are also the one the public worries about the most.  Rising damp is relatively rare and not that difficult or expensive.  Dry rot or beetle attack can often be related to dampness with lack of ventilation.  JW Surverys recommend on how these conditions can be improved.

There are different ways in which damp can affect a property.  Rising damp occurs when ground water soaks up into unprotected brickwork, stone masonry or through the softer mortar.  Ground water contains salts which absorb into a walls base.  This can cause damage to your home and if left untreated can lead to timber decay.  Rising damp happens when the existing damp proof course deteriorates.  This then allows water to absorb through the waterproof barrier which has weakened.

There are several tell-tale signs that your property might be affected by rising damp.  These signs may include crumbling low level plaster, a band of salt that has drawn out of the plaster, tidemarks along the of the internal or external brickwork, stained or peeling wallpaper or flaky plaster.  Treatment for rising damp may be installing a new damp proof course or maybe re-plastering with a water resistant render.  JW Surveys will send a fully qualified surveyor to carry out a thorough inspection.

Penetrating damp is as a result of poor external maintenance.  This could be from damaged gutters which allow rain water to penetrate the buildings structure when the external bricks or renders are cracked.  There are various causes of penetrating damp.  From porous bricks and stones to driveways, paths, lawns and patios which have been raised above the damp proof course against the external wall.  Missing or cracked roof slates or tiles could be another factor along with faulty flashing.

Signs of penetrating damp could be stained internal plaster, blown plaster, plaster falling off walls or peeling wallpaper.  JW Surveys can inspect all areas of concern and provide you with a suitable treatment to resolve your damp problem.  Sometimes no internal work is needed as once the source of the problem has been rectified walls may dry out naturally.  Although if plasterwork has been affected, it may need to be removed and re-instated using a waterproof rendering system and then a skimmed with a coat of finish plaster.  It is our aim to ensure that the dampness does no re-occur.

Condensation is mainly caused by warm, moist air from household activities condensing onto colder surfaces in the home such as walls, windows and ceiling.  These household activities include cooking, washing, bathing or even just breathing.  Condensation comes from water vapor being created from within a building that cannot escape.  Buildings that are poorly insulated walls are prone to this problem. 

The common sign of condensation is water collecting on the inside of windows or on the window sill. It is generally noticeable where it forms on non-absorbent surfaces, i.e. windows or tiles.  It can form on any surface and it may not be noticed until black mould growth and rotting of materials occur.  Other signs are decayed timer around window and door frames and water running down wall and pipes.  When sufficient moisture is present, species of bacteria and fungi can pollute the air in people’s homes.  Black mould can lead to an increase in respiratory problems such as asthma.  In particular the elderly and young children can be badly affected.

Condensation remedies may include background heat, additional ventilation, air vents, the use of fans and reduction of moisture generation.  At JW Surveys, we can provide you with an honest report and guide you in the right direction.

Our surveys are designed for a variety of clients including home owners, landlords, building contractors and developers.

Whether it is a diagnosis of rising damp or penetrating damp, the diagnosis will be the correct one.  We will carry out a full inspection and produce your personalised report within 48 hours.

The inspection will cover the accessible timbers of the roof and floors.  This will enable us to gain evidence of any infestation by wood-boring beetles/wood destroying fungi.  The first floor walls will be tested for damp ingress.  We will pay particular attention to areas at high risk of penetrating damp such as chimney breasts and walls adjacent to external water goods.  We will then look at the walls at ground level for evidence of rising damp from ground water and water ingress from internal or external defects.  We will also inspect the walls below ground level in basement areas for evidence of penetrating water from the ground.

JW Surveys will provide you with a comprehensive report which will cover the envelope of the property to assess its general condition.  External observations including photographs of areas of concern as well as an internal observation.  You will be provided with conclusions including a full plan highlighting the work required.  Specification and budget estimates are based on current industry rates.
