Access was gained to the roof void during the inspection. Timber moisture content readings of up to 30.3% WME were recorded to the rafter members. To give that context: readings above 20% are considered elevated, and anything above 28% indicates conditions where active wet rot decay is already underway. Staining, discolouration, and localised softening of the timber were all observed, consistent with active wet rot.

This is not a cosmetic problem. Wet rot in roof timbers weakens the structural integrity of the roof over time. Left unaddressed, it can lead to rafter failure and, in worst cases, partial roof collapse. The cost of a specialist timber treatment and replacement of compromised members is significant, particularly in a mid-terrace where scaffolding access affects both sides.

A specialist timber surveyor and roofing contractor were recommended to inspect the roof structure from scaffolding before exchange, with full reports and costings obtained.

The main roof is covered with Welsh slate. During the inspection, slipped, cracked, and displaced tiles were observed to the bay window roof and the main rear slope. Ridge tile mortar showed clear signs of deterioration. A brief drone survey was also undertaken which confirmed the extent of the tile movement.

Failed roof coverings allow water into the roof void. Water in the roof void accelerates timber decay. The two defects are directly connected. A comprehensive survey from scaffolding was recommended before exchange, with the roofer and timber specialist ideally attending at the same time.

Moisture readings of 46.5% WME were recorded to the lower section of the dining room wall. That is a very high reading. The property is of solid brick construction with no cavity, which is standard for this era. Without a cavity, there is no secondary barrier to moisture. The wall relies entirely on the integrity of its external surfaces, pointing, and any masonry coatings to stay dry internally.

The rear and side elevations had been previously painted with masonry paint that had extensively failed, with peeling, blistering, and loss of adhesion visible across large areas. Failed masonry paint traps moisture in the wall rather than allowing it to breathe, which accelerates deterioration. The leaking downpipe joint at the side elevation was also contributing water to the base of the external wall.

The fix is not simply redecorating internally. The source of the moisture has to be eliminated first. In this case that meant addressing the failed external paint, repointing the brickwork, and rectifying the drainage issues, before any internal remedial work could be meaningful.

Spirit level testing of the floor in the front bay window area and the kitchen both recorded notable slopes. In the bay, the floor appeared to be of suspended timber construction, indicated by the presence of a ventilation grille at skirting level. The possible causes include natural settlement over time, blocked subfloor ventilation, or the influence of the tree in the front garden affecting ground conditions beneath the shallow Victorian foundations.

Sloping floors on their own are not always a structural emergency in a Victorian property. What matters is understanding why they are sloping, and whether the slope is stable or progressive. Floor coverings had not been lifted at the time of inspection. The recommendation was to lift carpets to inspect the subfloor structure and joist condition before exchange, particularly given the blocked air bricks and the tree proximity.

A mature tree was identified within approximately 5 metres of the front elevation windows. Victorian properties of this era typically have very shallow foundations, either brick laid directly onto subsoil or a shallow mass concrete strip. Modern foundation depth requirements did not exist when this house was built.

Trees near shallow foundations in clay soils present a risk of subsidence, as root systems extract moisture from the soil and cause it to shrink. There is an equally significant risk in the opposite direction: if a large tree is removed without proper management, the soil reabsorbs moisture and can expand, causing heave damage to the foundations. Neither outcome is straightforward or cheap to fix.

An arboricultural survey and a structural engineer’s assessment were both recommended before exchange. A Cordyline plant growing directly against the front wall was also flagged, as its root system was potentially bridging the damp proof course and directing water into the wall.

Three air bricks were identified to the external walls. All were significantly obstructed by accumulated debris, cobwebs, and vegetation. One was completely blocked. Where suspended timber floors exist, air bricks are the only mechanism for ventilating the subfloor void. Block them, and you create stagnant, moist air conditions in the void below the floor. Those conditions are directly conducive to wet rot, dry rot, and wood-boring beetle infestation in the joists and decking.

This defect is quick and cheap to fix but the consequences of leaving it are not. All air bricks were recommended for clearance before occupation, with the subfloor void inspected at the same time.

Both chimney stacks showed deteriorated flaunching (the mortar fillet around the base of the pots), spalling brickwork, and failed pointing. Both stacks appeared to be redundant but deteriorated chimney stacks are a water ingress risk regardless of whether they are in active use. Water entering a chimney stack can track down through the stack and into internal walls and ceilings, causing damage that can be difficult to trace to its source.

A specialist chimney contractor was recommended to re-flaunch, repoint, and inspect the flashings at the junction of both stacks with the roof slopes before exchange.

Textured Artex-type coatings were noted to the bathroom ceiling and potentially in other areas. Coatings of this type applied before approximately 1999 have a possibility of containing chrysotile (white) asbestos fibres. The ceiling must not be disturbed, dry-sanded, or removed without prior testing by an accredited asbestos surveyor. The porch floor tiles were also flagged as potentially containing asbestos based on their age and type.

This is a very common finding on Victorian and Edwardian properties that were decorated or updated in the 1970s and 1980s. It does not prevent purchase but it does mean that any renovation or ceiling work requires an asbestos survey first.
