Retaining Walls in Mt Lebanon

Mt Lebanon was built as a streetcar suburb, and it shows in the terrain. The neighbourhoods running off Washington Road and Bower Hill Road were cut into hillsides in the 1920s through the 1950s, with houses set on narrow lots stepped up or down from the street. Almost every one of those properties has a wall doing structural work somewhere, and a large number of them are original to the house.

That age is the issue. A wall built in 1935 predates modern drainage practice entirely. Many of the older Mt Lebanon walls are dry-laid stone or early poured concrete with no drainage stone, no fabric and no drain line behind them, and they have been holding through ninety Pittsburgh winters on mass alone. They are not failing because anyone did anything wrong. They are simply at the end of what they were built to do.

The other Mt Lebanon-specific problem is access. Those narrow lots with houses close to the street mean that on a lot of jobs here, no machine reaches the back of the property. Block, stone and drainage aggregate move by wheelbarrow down a side path, and that changes what a wall costs. We price it honestly rather than quoting a machine-access figure and revising it on day one

Mt Lebanon Retaining Wall FAQs

Do I need a permit for a retaining wall in Mt Lebanon?

Mt Lebanon Municipality issues its own permits and generally requires one for walls over four feet, along with engineered drawings. Given how many Mt Lebanon properties sit close to a boundary or a right of way, setbacks matter here more than in newer suburbs. We confirm requirements with the municipality before starting.

Can you replace an original stone wall in Mt Lebanon?

Often we can reset it rather than replace it. Dry-laid stone walls can frequently be taken down, the hearting repacked, drainage added behind, and the original stone reset. On a house from the 1930s that weathered stone face is worth keeping, and it cannot be bought new.

How do you work on Mt Lebanon properties with no machine access?

By hand, and we say so in the quote. Many older Mt Lebanon lots have no route for a skid steer to the rear of the property. That means material moves by wheelbarrow and spoil comes out the same way, which affects both time and cost. It does not affect how the wall is built.
