Professional Woodworm Treatment in Cardiff
Wood-boring insects lay eggs in timber, and the larvae feed inside the wood for several years before emerging. Over time, this activity weakens joists, floorboards, roof timbers and structural beams.
Our approach is simple and effective:
- Accurate identification of the insect species
- Assessment of the extent of timber damage
- Targeted, professional woodworm treatment
- Repair or strengthening of affected timbers where required
We treat the cause as well as the infestation, reducing the risk of recurrence and giving you complete peace of mind.
Common Signs of Woodworm
Some of the most common signals we notice during woodworm surveys in Cardiff include:
- Small, round exit holes in timber
- Fine powdery dust (frass) beneath beams or floorboards
- Crumbly or weakened wood
- Tunnels visible within cut timber
- Damaged roof timbers in loft spaces
If you are unsure, we recommend arranging a professional inspection rather than relying on guesswork. Recognising the problem quickly helps reduce the risk of serious damage in structural timbers.
Structural Timber Repairs Where Needed
Many cases of woodworm can be treated without timber replacement, but in some cases, woodworm damage may require localised timber repairs or strengthening. Where structural integrity is affected, we can advise on appropriate remedial work and book our team of specialists to manage the job for you.
If decay is related to moisture issues, we may also recommend damp control measures to prevent future infestation. Any additional services are explained clearly, including a no-obligation quote with no unnecessary upselling.
Woodworm can affect properties of all ages, particularly where timber has been exposed to higher moisture levels. A professional survey confirms whether activity is current and whether treatment is required.
Whilst we often have same-week availability in Cardiff, it can be dependant on demand. Call 02920 290 558 to speak to us and find the earliest survey appointment that works for you.
Woodworm treatment costs depend on the type of infestation and the extent of the problem in the property. You will receive a written report following your survey that will include a clear quote for any recommended remedial works.
Of course – no matter if you are in the dead centre of Cardiff, or outside the city entirely, our team are going to be able to help. We cover the entire South Wales area, so if you need a survey, just get in touch!
Adult beetles can lay eggs in other suitable timber, which is why active infestations should be treated promptly. Addressing underlying damp issues is also important to reduce the risk of recurrence.
In most cases, you will be able to remain in the property during treatment. Our team will explain any precautions clearly before work begins.
