Chimney Sweep, Inspection and Repair in Ridgewood, NJ
More than half of Ridgewood's housing predates 1950. White powder on the brick, and what it says about water, is one of the first things to learn.
Ridgewood, in Bergen County, is largely owner-occupied single-family housing. The Census finds about 79% detached and 83% owner-occupied, with about 51% of homes built before 1950 and a median build year of 1950. The remaining 21% is attached or multi-unit housing.
For houses of this age the chimney is more likely to have been repaired at some point than left alone, so inspection often starts with reading earlier work.
This page focuses on one question homeowners raise often in older masonry: the pale deposits that appear on brick and mortar, and what they mean.
Housing profile
What the housing mix means in Ridgewood
More than half of homes predate 1950 and most are single-family. Where the housing is attached or multi-unit, a chimney may be shared or maintained by someone else, and we start by working out whose chimney it is.
What we look at
Where to look on an older brick chimney
The face of the brick
White powder, flaking or a rough surface signals water movement or freeze-thaw damage.
Joints
Mortar that is sandy, recessed or missing at the top is the usual first repair.
The cement crown
Cracks let water through to the brick below.
Where it meets the roof
Stains on interior walls near the chimney often trace back to flashing.

White staining on chimney brick
The white, powdery deposit often seen on brick is called efflorescence. Water moving through masonry dissolves salts and leaves them on the surface as it evaporates. The deposit itself is harmless and brushes off, but it tells you water is passing through the wall.
That makes it a useful diagnostic. Staining concentrated near the top suggests the crown, cap or upper joints. Staining near the base can point to flashing or ground-level moisture. Cleaning it off without finding the source means it comes back. See what causes white stains on chimney brick for the full explanation, and why water is coming into your chimney for tracing it.
White deposit is a symptom, not the problem. The job is to find the water path.
Older houses
Older houses and multiple fireplaces
Houses that old can have more than one fireplace or flue. Each flue needs its own check, and a flue no longer in use should be capped and closed properly. If you are thinking of opening up an unused fireplace, closing off an unused fireplace and inspection levels are the places to start.

Questions
Frequently asked questions
Should I power wash efflorescence off?
A dry brush is usually enough for the surface. Pressure can drive water deeper. The main job is to stop the water entering.
Is it safe to keep using the fireplace?
If there is no sign of damage in the firebox or flue and the chimney has been inspected, many people do. If you are unsure, have it checked first.
Who looks after a shared chimney?
That depends on the building. We will confirm with whoever manages it.
