Who we work with
A single point of contact for managed property
Whether you hold one rental or a portfolio of historic buildings, we handle the survey, the treatment and the certificate — so woodworm does not delay a sale, a letting or a refurbishment.
Landlords
Keep timber sound and lettings compliant. We work around tenants, treat in a single visit where possible, and provide the certificate your records and inventory need.
Landlords frequently ask whether woodworm treatment can be carried out in occupied rented properties — the answer is yes, with minimal disruption to tenants.
Letting & managing agents
A reliable contractor for survey requests across your managed stock, with one report format, clear pricing and certificates addressed however you need them.
Estates & portfolios
Repeat survey and treatment programmes for multiple properties, cottages and outbuildings, scheduled to suit voids, changeovers and seasonal access.
Listed & historic buildings
Careful treatment of old oak and protected timber, including death watch beetle, with methods chosen to respect historic fabric and consent requirements.
Property sales
When a survey flags woodworm mid-sale, we move quickly: a prompt inspection, a fixed quote and a guarantee certificate to satisfy the buyer and lender.
Offices, shops & hospitality
Low-odour, fast-drying treatment scheduled for closing hours or quiet periods, so trading and staff are not interrupted.
Why it matters commercially
Managed buildings hide the timber beetles prefer
Rentals, estate cottages, offices and listed buildings share a problem: large volumes of structural timber in places nobody routinely looks. Sub-floor voids, unconverted roof spaces, cellars and the ends of joists bedded into older walls stay cool and, where ventilation has been blocked, slightly damp. That is precisely the timber the common furniture beetle (Anobium punctatum) targets — and it accounts for roughly three quarters of UK infestations.
Because tenants change and access is intermittent, commercial woodworm is often discovered late: at a sale, an inventory check or a refurbishment, by which point a colony that has run a three-to-four-year lifecycle may have spread. In historic and listed stock the picture differs again. Old oak can harbour death watch beetle (Xestobium rufovillosum), which leaves larger 3mm holes and works slowly but seriously through structural hardwood over decades.
The right response always starts with correct identification. Some beetle holes are old and inactive, and treating sound historic timber needlessly is the wrong call for a protected building. Our surveyor confirms whether an infestation is active, identifies the species, and recommends only the work the timber genuinely needs — then puts it in writing.
Typical commercial findings
- Common furniture beetle
- 1–2mm holes in softwood joists, floorboards and roof timbers. The everyday cause in rentals and offices.
- Death watch beetle
- 3mm holes in old oak. Found in listed and historic buildings; slow but structurally serious.
- Wood-boring weevil
- A sign of damp, decaying timber — a flag to investigate an underlying moisture or rot problem too.
Minimal disruption
Treatment that works around your building, not against it
Commercial timber treatment lives or dies on disruption. We plan the work so tenants, staff and customers barely notice it.
Out-of-hours options
Early-morning, evening and weekend visits for occupied lets, offices, shops and pubs — work scheduled around trading and tenancies.
Phased & discreet
We can treat one floor or room at a time, in unbranded vehicles where preferred, so the property keeps operating throughout.
Fast drying, low odour
Water-based treatments are touch-dry within hours, so most areas can be reoccupied the same day after a short ventilation period.
Paperwork in order
Method statements, risk assessments and proof of insurance supplied in advance for managed and access-controlled sites.
Compliance & certificates
The paperwork a sale or letting actually needs
Woodworm tends to surface at the worst moment — when a homebuyer or RICS survey flags it part-way through a sale, or when an inventory clerk spots fresh frass at a tenancy changeover. At that point the buyer's solicitor, the lender or the incoming tenant wants two things: evidence the timber has been treated, and a guarantee that stands behind it.
Every job we complete ends with a written treatment report describing what was found and what was done, and a transferable 30-year guarantee certificate on the treated timber. These are the documents that close out a survey retention and reassure a lender. We can address them to the vendor, the landlord or the managing agent, and reissue them to a new owner where the guarantee transfers.
We carry public liability insurance, work to recognised industry standards and, where a site requires it, provide method statements and risk assessments before we arrive. For listed and historic buildings we work within the relevant consents and are glad to liaise with conservation officers and surveyors.
What you receive
- Written survey report identifying the species and extent
- Fixed, itemised written quote — no day-rate surprises
- Treatment certificate with a transferable 30-year guarantee
- Method statements and proof of insurance on request
For roof-space treatment, note that bats are legally protected and a roof may need a bat check first — we will advise during the survey.
