Damp Surveying

A damp survey will need to be undertaken to find the correct source of dampness. Without this, the source of damp might be assumed but there is no guaranteed proof. It is vital to know the exact source of dampness as treating the wrong damp problem can result in more harm than good. Therefore, a survey of the problem is needed to ensure effective damp proofing treatment is carried out.

The first step of surveying a building is an external examination. Pro Build Norfolk Ltd will check for signs of water ingress from the outside, such as cracks in the masonry leaking pipes or broken flashings and tiles. We will then examine the condition of brickwork, stone and mortar, chimneys, flashings, rainwater goods and valleys, as well as external timbers and the condition and fitting of windows, doors and air vents. In addition to this, the position of existing remedial damp proofing course and the ground levels will also be examined.

After the external examination, the inside of the building will be inspected for visible signs of dampness. Fungal decay in timbers, such as skirtings; the peeling or blistering of wallpaper and paintwork; efflorescence; mould growth and staining on walls; as well as damp patches, water droplets and water running down walls are all signs of dampness.

Once the initial internal examination has been completed a more in-depth look at the type of dampness will be carried out. A correctly calibrated and fully functional electrical moisture meter will be used for this damp examination. The moisture meter will be used to inspect the moisture content of timber skirting and observe the distribution of moisture meter readings horizontally and vertically on the surface of the walls. Additionally, we will assess the condition of floor/wall junctions and the edge of the damp-proof membrane, as well as the perimeter and centre of solid and timber, suspended floors. Whilst examining the floor it is advised to lift the floorboards and thoroughly inspect the timbers and subsite. The suitability of the subfloor ventilation should also be checked.

remedial damp proofing courses

If remedial damp proofing courses have previously been installed from the inside, their position and hole depth should be examined. When checking the condition of the walls, any use of polystyrene sheets or foil backing should be taken note of and, if present, the appearance of efflorescence beneath wallpaper finishes. If new plasterwork has recently been carried out, its condition, height and type should also be noted, as well as internal plumbing defects, water on cold pipes, etc.

A good damp surveyor will also investigate the history and use of the property, as the inhabitant’s lifestyle can affect the condition of the building. Once the damp survey has been carried out and a thorough examination of the property, the symptoms can then be analysed and Pro Build Norfolk Ltd will be able to offer a solution for the problems identified.

Wood Worm

Wood Worm Treatment For Your Property

The widespread use of timber in modern structural applications such as, floor joists, roof purlins, floorboards and rafters has increased the risk that timber pests pose to woodwork. If left untreated these insects will cause significant damage to your property, which can ultimately lead to structural failure of the building.

Although the adults can fly, woodworm is commonly brought into your home through the purchase of second hand furniture, and left, can cause significant damage to already owned expensive wooden furniture, which may be antique. Woodworm is in fact not a specific species of timber pest, but a generic term for the larval stage of many timber damaging beetles.

The Furniture Beetle, a small brown insect which is about 3mm to 5mm in length and flies quite willingly, is the commonest. The Furniture Beetle lays its eggs on rough, unpolished wood and as soon as they hatch the grubs bore directly into the wood leaving no trace until they emerge as beetles three years or so later, normally between May and September. Longhorn, Powder Post, Wharf Borer and Death Watch Beetles, the latter of which only infests in large, old, hardwood beams, all have a foothold in the UNITED KINGDOM.

The first sign of woodworm that most people will see is precise, rounded holes about 2mm across in timber surfaces, often accompanied by small piles of wood dust below them. Fresh holes show clean white wood within. Although the holes are made by emerging adult beetles that are, as a result, no longer a direct threat to the structure, larvae may still be tunnelling away inside the wood. Brittle edges to boards and to joists are also often a good indication of their inhabitance and the need for woodworm control measures to be carried out.

Condensation Control

Condensation is one of the most common causes of dampness in properties. Quite simply condensation is water that is released from moisture-laden air and deposited on cold surfaces. It is usually seen as a problem during the colder winter months. Examples of condensation are being able to see your breath in cold weather and when mirrors or cold taps steam up in the bathroom.

In your house condensation is often seen on windows being more noticeable on cold mornings, and possibly on external walls. Condensation is also found where air movement is restricted, such as in corners of rooms, behind items of furniture placed against walls and even in wardrobes or cupboards. Its presence can be first indicated by the development of black spot mould growth on walls and ceilings, and even furniture, clothes and other fabrics. Condensation could also lead to wood rot of affected timbers including suspended floors. Appropriate measures need to be taken to control condensation which can be achieved by ensuring an adequate balance between heating, ventilation and insulation. Pro Build Norfolk Ltd can supply Airflow products such as The Auto Concure 20/20 PIV unit which is the most technically advanced system available and provides a whole house solution to condensation.
