RICS Level 2 Survey in B23

Terraced and semi-detached homes are the dominant property types in B23, accounting for the vast majority of transactions. References to period semis and Victorian terraced houses across Erdington and adjacent streets confirm that pre-1945 construction makes up a significant share of the local stock. Many of these properties were built during Birmingham's late-Victorian and Edwardian expansion to house factory and workshop workers, using traditional solid brick construction and lime mortar.

Pre-1919 solid wall construction means there is no cavity between the inner and outer brick leaf. These walls depend on brick thickness and lime mortar pointing for weather resistance. A consistent maintenance failure our surveyors identify in Birmingham's older terraces is repointing carried out with hard sand-cement mortar rather than lime. Hard mortar does not flex with seasonal temperature changes, traps moisture within the brick face, and accelerates surface spalling. Repointing a standard B23 terraced house in lime mortar typically costs between £2,500 and £5,500 depending on the property's extent.

Inter-war semis built between 1919 and 1939 introduced cavity wall construction to much of inner Birmingham, including B23. These properties offer better inherent damp resistance than solid-wall terraces but bring their own concerns: cavity wall insulation retrofitted in the 1980s and 1990s can block drainage at the base of the cavity if installed incorrectly, driving damp inward. Our surveyors check for this pattern in all inter-war properties and record damp meter readings at the base of external walls.

• Pre-1919 solid brick construction prevalent across Erdington's Victorian terraced streets
• Inter-war cavity wall semis common from 1919 to 1939, with retrofitted cavity insulation risk
• Original sash windows and cast-iron rainwater goods remain in many properties
• Rear outrigger extensions are common and regularly show junction damp and movement
• Post-war infill properties sit alongside Victorian stock on many B23 streets

B23 is one of Birmingham's more affordable inner suburbs, with an average house price of £196,010 compared to £362,470 in Harborne (B17) and £315,372 in Moseley (B13). Erdington's good transport links into Birmingham city centre and its access to employment along the A38 corridor make it attractive to both first-time buyers and buy-to-let investors. The B23 6LA sub-area's 23% price growth in the last year reflects increasing demand from buyers priced out of further south.

The concentration of terraced and semi-detached sales in B23 - 780 and 549 transactions respectively since 2021 - means the market is active and properties move at pace when priced correctly. For buyers, this increases the pressure to commit quickly, which makes having a pre-purchase survey even more valuable. The survey gives you a factual picture of the property's condition before you are financially committed.

For investors buying in B23, the survey findings also inform maintenance budgeting. A property with a Condition Rating 2 roof and outdated electrics is not necessarily a bad purchase, but it is a purchase that requires a clear plan for the first 12 to 24 months of ownership. Our report gives you the specific information needed to make that calculation before exchange.
