Treatments

Treatment varies with the type of timber pests. Treatment A is the basic treatment against the majority of insect pests. Please note the exceptions and modifications.

Treatment A. Surface Treatment with (Organic Solvent or ‘Micro-emulsion’) Insecticidal Fluid (STIF)

All accessible timbers (ie not those hidden by being buried in masonry, etc) should be exposed by the removal of floorboards at suitable intervals, or other coverings, where this is deemed necessary and must be dusted down (if needed) sufficient to allow fluid penetration, and treated by the application of an organic solvent borne insecticidal fluid at our recommended concentration. All floors or other timbers must be re-laid, or replaced where structurally unsound. Any wiring, junction boxes, water tanks, insulated piping etc, must be protected during the course of treatment. Where treatment is extended to joinery timbers, the details of removal or treatment must be individually specified in the report.

This Treatment A is suitable for all the common wood-boring insects (except the Wood Boring Weevil) together with suitable modifications where the following insects are found:

The House longhorn beetle will in addition require supplementary works involving the removal of all defective sapwood (the outer part of the original tree), together with supplementary strengthening of these timbers to comply with the given strength requirement. Treatment of existing timbers and cut ends of new CCA-treated timbers must be carried out.

The Deathwatch beetle treatment may include several successive annual smoke canister applications of insecticide during the `flight season’, together with the selective drilling of large dimension timbers to apply the fluid directly to the site of the attack and also the use of preservative pastes.

Treatment B. Wet Rot Treatment (WRT)

Our report will specify the action for removal of the cause. The cause must be rectified under a separate contract, perhaps by the client’s builder, together with:

  1. The removal of structurally unsound timbers
  2. If justifiable after a COSHH assessment, the treatment of the remainder by Surface Treatment with Fungicidal Fluid (STFF) or perhaps a preservative paste.
  3. The replacement of the removed timbers with sound copper-chrome-arsenic (CCA-) treated timber.

Only where justifiable under COSHH, can extra protection can be given by treatment with an insecticide to protect against future insect attack.

Treatment C. Dry Rot Treatment (DRT)

Almost without exception the elimination of dry rot is a two stage process.

Stage 1. Exposure Works

Elimination of the cause of attack (as for WRT) together with exploratory works. These exploratory works, such as the removal of plaster and defective timbers, are designed to establish and define the full extent of the attack. A report of these findings is prepared and then a fixed price quotation for the next stage, viz:

Stage 2. Treatment Works

Owing to the persistent and often hidden nature of the attack by this fungus, it is often necessary to carry out extensive ancillary works in addition to timber replacement. The nature and extent of these will be carefully and unambiguously detailed in the report and will include some or all of the following:-

  1. The removal of all structurally defective timbers affected by the fungus, possibly with apparently sound timbers up to 1m from the nearest visible decay as determined on site by ATICS.
  2. The removal of all plaster/rendering within the affected area and up to 1m beyond as determined by our surveyor. This to be followed by the brushing down or vacuuming of exposed brickwork.
  3. For timber, Surface Treatment with Fungicidal Fluid (STFF) and/or for masonry, a masonry biocide, in a manner and to an extent detailed in the report. For timber this treatment is likely to be restricted to wet, large section timbers at risk and for masonry may include the drilling of holes at staggered centres around the perimeter of the exposed brickwork such as to form toxic barriers through and around the affected masonry.
  4. Replaster with any cementitious or lime plasters, for example a sand;cement render or `Limelite’ renovating and finish (vermiculite lightweight aggregate and gypsum and lime plaster). Renew any ceiling surfaces using plasterboard together with a finish coat of retarded semi-hydrate board finish such as `Thistle’. Zinc Oxychloride fungicidal plaster can be used in special circumstances in accordance with the manufacturer’s specifications (Preservation Centre for Wood Ltd., 24 Ossory Road, London SE1 5AP).
  5. For areas not due for plastering, such as reveals, apply two coats of ZOC fungicidal paint to all brickwork to which treatment timbers are to abut.
  6. Install suitable, treated replacement timbers as detailed in the report.

    (b) ensure that the electricity supply to any circuits within the treatment area are cut off and remain cut off during the course of this treatment.
  5. The report remains the property of ATICS Ltd and may not be used, relied on or copied until paid for in full. It is an express contract term that no liability accrues to us from any reliance on a report that has not been paid for in full including any ‘extras’ and associated costs, such as interest.

  8. Unless a “full” survey as described in our General Information Leaflet No 1 (GIL 1) has been requested and confirmation in writing received by us, any work done is limited as agreed in the brief and by these terms and conditions of contract freely entered into and provided to you prior to contract.
  9. The detailed inspection of the degradation of external joinery timbers subject to weathering and requiring maintenance is not within the normal scope of our inspection.
  10. We will not have inspected woodwork or other parts of the structure which are covered, unexposed or inaccessible and we will, therefore, be unable to report that any such part of the property is free from defect.

Accordingly, the scope of our survey will be commensurate with the above conditions.
