How to repair Woodworm damage

1. Sound the timbers with a hammer and drill holes to establish the extent.

2. Cut out seriously weakened areas and (if less than 30% of the cross section is weakened, subject to survey) fill with Moulding Mortar

3. Remove structurally damaged sections and replace with Timber-Resin Splices.

Moulding Mortar can be shaped, carved and stained like wood

Moulding Mortar Repair
Example

Doddiscombeleigh Church - the Nave has a barrel vaulted ceiling, made of Oak frames with pine planking. One of the frames had been eaten away by Death Watch Beetle in the most visible place in the centre of the arch. The repair was made using Epoxy-glass flexible rods, which were used to form a frame to follow the original shapes. This form was then filled out with Moulding Mortar, a shrink proof epoxy putty like material that can be formed, shaped and carved to any shape. After carving the finished surface was stained to match the original.

Any shape of arch can be replaced with Timber-Resin Splice units - Kathy, Grand Apartments, Manchester

Woodworm Damage
Testimonial

Doddiscombeleigh Church Barrel Vault Ceiling - one of the moulded arches was badly eaten out by Death Watch Beetle. The mid-span area was missing. Flexible Epoxy Glass rods were used to form a new frame for the shape and Moulding Mortar was hand placed and carved to form the complex shape. The final surfaces were sanded and stained to match the original.

How to prevent Woodworm

1. Ensure that dampness and humidity are controlled (e.g. ventilate roof and sub-floor voids)

2. Treat vulnerable timber surfaces with Boron Ultra 12 by spray/blower or brush. Treat end grain with Boron Gel.

3. Check annually until no more flight holes appear. Re-treat if further fresh activity appears after 5 years.
