Project Description

DAMP CONTROL

If a property is suffering from damp,
your first step should be to contact us.

Rising Damp

Rising Damp occurs when water from above or below ground enters a building through its walls or floors, untreated this can cause damage to the fabric of the building.

Common signs

Rising damp can cause blistering paint, loose wallpaper or softened plaster which will eventually fall off the walls. Walls may be stained with a ‘tide-mark’ and the room or house can smell damp or mouldy. Damp often results in rotten joinery and timbers which allows fungus to develop.

Causes

An absent or damaged DPC (damp proof course) is often the root cause of damp issues. Another contributing factor occurs when external ground levels have been raised over time by driveways or flower beds bridging the DPC. This bridge allows groundwater to find a path into the fabric of the building.

If left untreated any issues will gradually worsen.

Survey

We can arrange for one of our specialist surveyors to undertake a survey to identify what type of damp problem you have. We will provide a report and offer treatment advice as appropriate.

Penetrating Damp

Penetrating Damp is the passage of rainwater into the building structure causing deterioration internally. If left untreated this can cause extensive damage.

Common signs

Penetrating damp can cause blistering paint, loose wallpaper or softened plaster which will eventually fall off the walls. This is often localised to an external defect, which can result in rotten joinery and timbers which allows fungus to develop.

Causes

Poorly pointed brickwork, cracked render, faulty roof flashings or defective guttering and drainage can all allow rainwater to enter the fabric of the building. Leaking plumbing can also give rise to penetrating damp.

Survey

You can protect your property from penetrating damp by keeping it in a good state of repair. Ensure that brickwork, pointing, roofing and gutters are maintained in good condition. We can arrange for a survey to identify the areas of concern, provide a report and offer treatment advice as appropriate.

Condensation – High Humidity

Condensation is one of the most common forms of damp.

Common signs

Windows that stream with water internally, mould growth on walls and ceilings and a musty smell. Any sign of mould growth is an indication of the presence of moisture and if caused by condensation gives warning that heating, structural insulation or ventilation may require improvement.

Causes

Condensation tends to happen more frequently during the winter months as the building structure is cold and because windows are opened less meaning the moist air is unable to escape.

Condensation can often occur for short periods in bathrooms and kitchens because of the steamy atmosphere and frequently for long periods in unheated bedrooms and cupboards or behind large items of furniture where the movement of air is restricted.

Damage can be caused to materials that are out of sight, for example, under suspended timber floors and in roof spaces.

Survey

Our Surveyors can assist in establishing if condensation is the cause of damp problems in a property. We can give advice to help solve condensation problems for home owners, landlords, housing associations and letting agents.

DAMP SURVEY

APP can provide you with advice on any aspect of dampness, structural waterproofing or timber preservation. Contact us by phone, email or via the contact form on this website. We will discuss your requirements and where appropriate make an appointment with you for one of our qualified surveyors to visit and carry out a survey.

Our site surveys, which include a comprehensive written report, remedial specification and where necessary an estimate for work, are provided within five working days of the survey.

Our reputation for integrity and accuracy has been hard-won and our Surveyors are not paid commission. All are fully qualified as Certified Surveyor of Timber and Dampness in Buildings (CSTDB) and Certified Surveyor in Structural Waterproofing (CSSW) and we are members of the Property Care Association (PCA).

Once you have reviewed the report, we will be happy to answer any questions you may have.

CODE OF PRACTICE

  • As with our surveyors, our installation teams are employed directly by us.
  • Our installation teams carry ID and arrive on time, in sign-written vehicles.
  • We never forget that this is your home and we treat it like your home, our team are thorough, clean and tidy.
  • Some aspects of damp treatment can be dusty and noisy, we use industrial standard dust barriers to keep mess to a minimum and we clean up properly once we are done.
  • Our specialist partner sub-contractors also work to our code of practice.

DAMP CONTROL FAQs

Our surveyors are qualified to Certified Surveyor of Timber and Dampness in Buildings (CSTDB) and Certificated Surveyor in Structural Waterproofing (CSSW) standard. This is the industry standard accreditation administered by the Property Care Association.

No. This is one of the most pervasive myths in our industry. It is probably a hang-over from a time when the chemicals employed to treat damp and timber problems were solvent based. We switched to water-based chemicals about 25 years ago and there are no odour problems associated with these.
