Timber infestation occurs when wood-boring insects attack structural timber and wooden elements in buildings. Our specialists identify the specific type of insect responsible and implement targeted treatments to eliminate active infestations and protect your property from further damage.
Different species of beetles create distinct patterns of damage. The common furniture beetle leaves small flight holes and fine frass that resembles sawdust. House longhorn beetles (common in London and the South East) create larger exit holes and can cause severe structural damage by consuming the core of the timber.
Other threats include deathwatch beetles and wood boring weevils, each of which requires specific approaches to treatment.
At Renlon, we’re constantly developing better solutions for our clients and the properties that we work on. Our innovation has led to the creation of proprietary products that offer significant advantages over traditional methods.
RenStrength is our revolutionary waterproofing system that eliminates the need to remove existing renders. This breakthrough technology applies directly over failed waterproofing systems, significantly reducing project timelines and disruption.
We are also excited to introduce RenTherme…
Our timber treatment begins with a thorough assessment to determine if you have an active infestation, identifiable through fresh frass, new flight holes, visual inspection, and other methods.
We usually start by evaluating the moisture content of affected areas. Dampness often encourages woodworms and related fungi.
Based on our findings, we apply the most suitable treatments.

Here are some common questions about timber infestation. If you need specific advice about your property, please contact us.
Contact UsLook for small round holes (1-2mm for common furniture beetle) in timber, fresh sawdust-like frass around these holes, and weak or crumbling wood.
Different types of wood boring insects create distinctive patterns - furniture beetle typically affects softwoods and European hardwoods, while deathwatch beetle prefers older, partially decayed hardwoods often found in historic buildings.
We are experts at surveying and identifying and will diagnose the exact issue your building is facing.
Yes, adult beetles can fly to lay eggs on other suitable timber surfaces. The risk increases when multiple pieces of infested timber are present.
An untreated woodworm issue can gradually spread throughout a building, affecting floorboards, joists, furniture, and structural elements. Prompt treatment prevents this proliferation.
Absolutely. The beetles themselves are rarely seen as they have short adult lives. The woodworm infestation is primarily evidenced by flight holes and frass. It's also important to distinguish between active infestations and old flight holes from previous activity.
Our experienced surveyor can determine if treatment is necessary or if the infestation is historic and no longer active.
