What we do

Specialist treatments.
Honest advice.

We survey first, identify the root cause, and apply the right solution. Not the most expensive one.

Damp Proofing

Rising damp, penetrating damp and water ingress left untreated will destroy plaster, rot timber and create conditions for mould. We find the source and eliminate it properly.

  • Rising damp diagnosis and treatment
  • Chemical damp proof course injection
  • Penetrating damp solutions
  • Heavy-duty plastic membrane sheet installation
  • Re-plastering with waterproof render

Timber Treatment and Dry Rot

Dry rot and wet rot attack structural timbers silently. Untreated fungal decay can compromise floors, joists and roof timbers before you even know it is there.

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

Woodworm Treatment

Wood-boring beetles can be active for years before becoming visible. We identify the species, assess the damage and treat with Biokil Crown approved insecticidal products.

  • Active woodworm identification
  • Insecticidal boron treatment
  • Roof timbers, floors and furniture
  • Pre-purchase surveys
  • Biokil Crown approved products only

How we survey

We find the problem first.
Then we fix it.

Every job starts with a proper survey using professional equipment, so you get the right treatment, not just the most expensive one.

Protimeter Surveymaster moisture meter

Protimeter Surveymaster
Precision moisture readings from 1 to 999. We measure exactly where damp is present and how severe it is before any work begins.
FLIR thermal imaging camera

FLIR Thermal Imaging
Reveals cold spots and moisture behind walls without any damage to your property. The darker areas show where damp is lurking, even where the eye cannot see it.
Aerial survey

We go where others can't.

Damien uses a professional drone to inspect roofs, chimney stacks, guttering and high-level brickwork from above. Most damp problems start at the top. Cracked pointing, missing tiles, failed flashing. We find them before they reach your walls.

Problems at roof level cause damp at ground level. Our drone survey means we can identify the source of penetrating damp without expensive scaffolding, saving time and giving you a complete picture before any work begins.

Roof to floor.
Every timber treated.

Woodworm can be active for years before it becomes visible. By the time you see the exit holes, the damage is already done. We ask that the loft is cleared as best as possible and insulation removed prior to our visit, so we can treat every accessible timber thoroughly with our insecticidal pump system.
