Say goodbye to damp problems with our fast, effective, and lasting solutions. Here’s how we help you:
- Rising damp - Rising damp occurs when moisture moves upward through porous masonry from the ground. Typical clues can include a low-level tide mark, crumbling skirting, damaged plaster and salts on the wall. Similar symptoms can be caused by leaks, high external ground levels or condensation, so the diagnosis must be based on the full pattern of evidence.
- Penetrating damp - Penetrating damp is moisture entering laterally or from above through a defect in the building envelope. Common sources include roof leaks, chimney defects, damaged render, failed pointing, leaking gutters, cracked seals and plumbing faults. The first priority is to stop the water entering; internal repairs come afterwards.
- Condensation and black mould - forms when moisture-laden indoor air meets a colder surface. It is often seen on windows, external walls, ceilings and corners with poor air movement. Effective treatment may involve improved extraction or ventilation, better heating control, attention to cold bridges and safe mould removal. Simply spraying or painting over mould does not remove the cause.
- Damp around chimneys - Chimney damp may be caused by damaged flashing, open or defective pots, failed pointing, cracked flaunching, rain penetration or salts left by decades of combustion. Redundant chimneys can also suffer when ventilation has been removed. We inspect the pattern before specifying repairs.
- Timber decay, dry rot and wet rot - Timber decay needs moisture. A proper treatment plan therefore deals with the water source as well as the affected wood. Depending on the extent of damage, work may involve improving subfloor ventilation, treating or replacing timber and repairing the building defect that allowed moisture to persist.
- Woodworm and timber preservation - Small holes in timber do not always mean an active infestation. We inspect the timber, surrounding conditions and signs of recent activity before recommending treatment. Where treatment is justified, the aim is to protect sound timber and identify any sections that require repair or replacement.
- Basement and below-ground waterproofing - Rooms below ground level are exposed to different moisture pressures from rooms above ground. Suitable systems may include a cavity drainage membrane or another waterproofing approach selected for the construction, intended use and drainage conditions of the space.

Why damp problems vary across Poole
Poole has a diverse housing stock, so a one-size-fits-all treatment is unlikely to produce a reliable diagnosis. The right response depends on where the property is, when it was built, how it was altered and how it is currently used.
Victorian and Edwardian homes in Ashley Cross, Parkstone and Heckford Park
Ashley Cross contains substantial Victorian and Edwardian development, including brick properties with slate roofs, prominent chimneys and shallow front gardens. Heckford Park also contains cohesive streets of Victorian and Edwardian terraces and semi-detached homes. In buildings of this age, solid walls and traditional materials can manage moisture differently from modern cavity-wall construction. Cement-rich render, dense plaster or poorly planned insulation can sometimes slow drying, so an injected damp-proof course should never be treated as the automatic answer to every stain.
Coastal exposure in Sandbanks, Canford Cliffs and harbour-side locations
Living near the coast does not automatically give a property “coastal damp”. It can, however, place more weather stress on exposed render, pointing, roof coverings, chimney details, windows and seals. Wind-driven rain can find small defects that remain invisible in dry weather. Low-lying harbour-side properties may also need careful investigation where historic flooding, drainage or ground moisture is part of the picture.
Converted flats, modern apartments and tightly sealed homes
Poole also has many flats, conversions and newer homes. Here, the more common problem may be condensation rather than water entering through the ground. Cooking, showering, drying laundry and everyday occupation release moisture into the air. If ventilation is weak or surfaces are cold, that moisture can condense around windows, external corners, wardrobes and behind furniture, creating the conditions in which mould grows.
Chimneys, roofs, gutters and older external details
Older Poole properties often retain chimney stacks, slate roofs, brickwork and rendered elevations. Defective flashing, porous pointing, overflowing gutters, cracked render and blocked rainwater goods can all produce penetrating damp. Treating the internal wall without repairing the external defect is unlikely to provide a lasting result.

How much does damp proofing cost in Poole?
The cost depends on the cause and extent of the problem. A ventilation improvement, small external repair or localised mould treatment is a very different job from removing plaster across several rooms, installing a new damp-proof course or waterproofing a basement. Generic online prices often compare unlike jobs and can be more misleading than useful.
Damp HQ provides a free survey and a written, itemised quotation before work starts. The quotation explains what is included, what must be completed first and whether drying or redecoration will be needed afterwards. The quoted price is the price you pay unless you approve a clearly explained change to the scope.
