What kind of homes and basements does Pittsburgh have?
Neighborhoods such as Lawrenceville, Bloomfield and Brookline are full of pre-1940 rowhouses and frame homes on stone, brick or block foundations. Many homes are built into slopes, with retaining walls and partially exposed basement walls.
What causes basement and foundation problems in Pittsburgh?
Hillside groundwater
Water moving downhill collects against uphill walls; interior drainage on that side plus surface drainage above is typical.
Bowing block and stone walls
Clay soils over shale push on walls, and freeze-thaw accelerates the movement.
Landslide-prone slopes
Some Pittsburgh slopes are prone to slow landslides; settlement or new cracks near steep grades should be assessed by an engineer.
Shared walls in rowhouse neighborhoods
In attached rowhouses in neighborhoods like Lawrenceville, one home's failing gutter or yard drain can send water into the neighbor's basement. Fixes work best when neighbors coordinate on downspouts and grading.

What do Pittsburgh homeowners ask most?
Is my Pittsburgh foundation moving because of the hill?
It can be. Slopes, clay soils and in some areas old mining can all move foundations. New or widening cracks near a steep grade warrant an engineer's assessment before repair.
Does a Pittsburgh basement contractor need to be registered?
Pennsylvania requires most home improvement contractors to register with the Attorney General's office; ask for the registration number and proof of insurance.
What causes the white powder on my Pittsburgh basement walls?
That is usually efflorescence: mineral salts left behind as water moves through masonry and evaporates. It is a sign of moisture passing through the wall, not mold, and it points to where drainage or crack repair is needed.
