Damp Surveys & Treatment in Kent
Damp has several causes and each needs a different fix. Moisture can rise from the ground, push through a wall from outside or form on cold surfaces inside the home. Treating it at the source is what makes the difference, leaving drier, healthier rooms and protecting plaster, timber and decoration from further harm.
Once the cause is clear, the treatment can be a new damp-proof course for rising damp, repairs to the outside of the wall for penetrating damp, or better ventilation and mould control where condensation is the problem. Where damp has led to dry rot, affected timbers are cut out and replaced.
We give you honest advice on what we found and what we recommend, so you can weigh up the options before any work is booked. Steadfast carries out damp proofing for homeowners, landlords and commercial premises across Maidstone, Kent and South East London.

Signs You Need Damp Proofing
Tide Marks on Walls
Staining, salts or crumbling plaster along the bottom of ground floor walls can point to rising damp.
Damp After Rain
Patches that grow or darken after wet weather suggest water is getting through the wall from outside.
Mould & Wet Windows
Mould on ceilings, corners and window reveals is usually condensation, which needs better ventilation.
Musty or Soft Timbers
A musty smell, cracked skirting or floorboards that give underfoot can all be early signs of dry rot.

Our Damp Proofing Process
Finding the Cause
Walls, floors and timbers are checked and moisture readings taken to tell rising damp, penetrating damp and condensation apart.
Stopping the Water
The source is dealt with first, whether that is a failed damp-proof course, a defect in the outside wall or poor ventilation.
Removing Damaged Material
Salt-laden plaster is stripped back and rotten timber cut out so the treatment reaches the affected area.
Making Good
Walls are replastered with suitable materials, timbers replaced, and the area cleaned up ready for decorating once dry.
