What we do

Specialist treatments for
damp, rot & timber

Every property is different. We survey first, identify the root cause, and apply the right treatment - not a one-size-fits-all approach.

Damp Proofing

Rising damp, penetrating damp and water ingress are among the most damaging problems a home can face. Left untreated, they destroy plaster, rot timber and create conditions for mould growth.

  • Rising damp diagnosis & treatment
  • Chemical damp proof course injection
  • Penetrating damp solutions
  • Tanking & basement waterproofing
  • Re-plastering with waterproof render

Timber Treatment & Dry Rot

Dry rot and wet rot attack structural timbers silently. Early identification and treatment is essential - untreated fungal decay can compromise floors, joists and roof timbers.

  • Dry rot eradication & treatment
  • Wet rot diagnosis & repair
  • Structural timber treatment
  • Floor joist & beam inspection
  • Fungicidal spray treatment

Woodworm Treatment

Woodworm (the larvae of wood-boring beetles) can be active for years before becoming visible. We identify the species, assess the damage, and treat affected timbers with Biokil Crown approved insecticidal products.

  • Active woodworm identification
  • Insecticidal boron treatment
  • Roof timbers, floors & furniture
  • Pre-purchase surveys
  • Photos & video of every stage

How we work

We find the problem first.
Then we fix it.

A lot of damp companies skip the diagnosis. We don't. Every job starts with a proper survey using professional equipment - so you get the right treatment, not just the most expensive one.

Our moisture meter gives a precise reading from 1 to 999 - the higher the number, the greater the moisture content. It tells us exactly where damp is present and how severe it is, before any work begins.

Thermal imaging reveals cold spots and moisture behind walls without any damage to your property. The darker purple areas show where cold, potentially damp patches are lurking - even where the eye can't see them.

"Damien came out to assess a potential damp problem. Our assessment was that we did not have any water ingress and therefore did not need a damp report. We fully expected to pay at least something for our time, but there was no charge. 100% trustworthy company. Very impressed."

"Damien came and gave a couple of different quotes depending on the amount of work we wanted doing, popped round again before the appointment to confirm everything, and cleaned up after. Really pleased with the work done."
