WhatsAppInvestigate
Start with the visible symptoms, where they appear and what may be happening around them.
Damp and moisture services
Property preservation and full house renovations in one place.
AP Property Preservation keeps the service journey simple: understand the problem, explain the cause and carry out the right preservation work for the property.

Start with the symptom
What are you noticing at the property?
Damp, timber decay, mould and wall-tie concerns can look similar at first. Start with the symptom, then choose the most relevant service area before contacting Andrew.

Explain
Give plain advice on likely causes before a treatment route is agreed.
Preserve
Keep remedial work proportionate to the property, defect and agreed outcome.
Protect
Aim for practical preservation, tidy workmanship and a clearer route forward.

Ask Andrew about this group
01.01Damp and moisture01
Damp investigation
Assessment-led advice to understand where moisture may be coming from before recommending work.
Damp patchesTide marksPeeling paintMusty smells
Risk if ignored
Moisture can be misread, leading to repeat plaster damage, mould growth and money spent on the wrong repair.
Check with Andrew
01.02Damp and moisture02
Rising damp treatment
Help where moisture appears to be travelling up through walls from ground level.
Low-level stainingSalt marksDamaged skirtingBlown plaster near floor level
Risk if ignored
Low-level salts, skirting damage and blown plaster can return after decoration if the cause is not checked.
Check with Andrew
01.03Damp and moisture03
Penetrating damp treatment
Advice and remedial work where rainwater or external defects may be allowing moisture into the building fabric.
Isolated damp patchesStaining after rainDamaged plasterExternal wall concerns
Risk if ignored
Rainwater entering the fabric can spread beyond the first visible mark and damage internal finishes over time.
Check with Andrew
01.04Damp and moisture04
Condensation and mould control
Practical guidance where everyday moisture, ventilation and surface temperatures may be contributing to mould growth.
Persistent mouldWindow condensationMusty smellsCold wall surfaces
Risk if ignored
Persistent mould can affect comfort, indoor air quality and decorated surfaces if the pattern is not addressed.
Check with AndrewTimber preservation
Treatment-led preservation for timber affected by insects, damp conditions or fungal decay.
Service images include illustrative examples. Visit our project gallery for photographs of remedial work.
Ask Andrew about this group
02.01Timber preservation01
Woodworm treatment
Help with suspected wood-boring insect activity in floors, roof timbers, garages and older properties.
Small exit holesFine dustWeakened timberHistoric or active-looking damage
Risk if ignored
Active infestation can continue weakening vulnerable timber, especially in floors, roofs and older outbuildings.
Check with Andrew
02.02Timber preservation02
Wet rot treatment
Investigation and treatment where damp timber has softened or decayed.
Soft timberDark stainingLocalised decayDamp timber near leaks
Risk if ignored
Rot can progress where timber stays damp, turning a local repair into a larger structural or flooring issue.
Check with Andrew
02.03Timber preservation03
Dry rot treatment
Careful help with suspected dry rot where fungal decay may be affecting timber or masonry-adjacent areas.
Brittle timberCuboidal crackingFungal growthMusty odours
Risk if ignored
Suspected dry rot should be treated seriously because decay can move through concealed areas if conditions allow it.
Check with Andrew
02.04Timber preservation04
Timber treatment
Preservation treatment for vulnerable or affected timber as part of a broader remedial plan.
Historic damageDamp exposureSuspected infestationTimber in floor or roof voids
Risk if ignored
Timber exposed to damp or insects can lose strength gradually, often before the full extent is obvious.
Check with AndrewStructural and waterproofing
Specialist preservation work for below-ground spaces, water ingress and wall-tie concerns.
Service images include illustrative examples. Visit our project gallery for photographs of remedial work.
Ask Andrew about this group
03.01Structural and waterproofing01
Basement waterproofing
Advice and work for cellars and below-ground areas affected by moisture or water ingress.
Wet cellar areasDamp masonryWater trackingPoorly usable storage space
Risk if ignored
Below-ground moisture can limit use of the space, damage stored items and stop finishes lasting.
Check with Andrew
03.02Structural and waterproofing02
Below-ground tanking
Tanking and related below-ground work to help make basement spaces drier and more usable.
Damp retaining wallsWet floorsCellar stainingPersistent below-ground moisture
Risk if ignored
Poorly controlled water can push through weak points and cause repeat damp, staining and failed finishes.
Check with Andrew
03.03Structural and waterproofing03
Wall-tie replacement
Replacement of wall ties where deterioration is identified and remedial work is appropriate.
Horizontal crackingBulging masonryCorroded tie concernsSurveyor comments
Risk if ignored
Failed wall ties can contribute to cracking, bulging masonry and more serious stability concerns if ignored.
Check with Andrew
03.04Structural and waterproofing04
Structural crack stitching
Crack stitching and reinforcement where masonry cracking needs a structural repair approach.
Stepped crackingRender cracksMasonry movementCrack repair evidence
Risk if ignored
Structural cracks can reopen or worsen if movement is only covered cosmetically rather than reinforced properly.
Check with Andrew
03.05Structural and waterproofing05
Structural waterproofing
Preservation-focused waterproofing support for complex damp and below-ground problems.
Persistent water ingressBelow-ground dampComplex moisture routesFailed previous work
Risk if ignored
Complex water ingress can worsen if treated cosmetically while the underlying route remains active.

Arrange a house visit to get the right route.
Many damp, timber and wall-tie symptoms look similar. Andrew will assess the issue at the property before recommending work or preparing a quote.
