Looked at a brick double wythe home from 1905 with various types of deterioration visible in the basement.
I’d like to see a NACHI.TV show on evaluation of old brick wall structures. Variations in brick manufacture, mortar mixes, construction methods and how the ways that these things have changed over the years has resulted in different types of defects.
I think this would help inspectors identify defects and describe how serious they are, whether they’re likely to continue and the likely causes.
It might also help them date changes in the home structure, which can be an issue in homes over 100 years old.
Does anyone else find this stuff interesting?
Furnace and water heater vented into a chimney. Looks like it has a continuous flue, but check out the debris in the cleanout beneath the point at which the flues enter the chimney.
If it doesn’t have a continuous flue and deterioration continues it could block the exhaust vent. Or the sealant could shrink and crack.
Note brick/mortar damage from window leakage. You can also see at this window one of two sewer pipes which left the home (ABS disappeared into mortar and wall). The other is the PVC pipe in the last photo (3" to 6").
