What Foundation Problems Affect Boerum Hill Row Houses?

Row houses built in the 19th century sit on old foundations, usually stone or brick, that have carried the weight for more than a hundred years. Time brings cracks, damp, mortar loss and settling, and construction on neighboring lots can add movement of its own.

The neighborhood is inland, so the main water issue is heavy rain and sewer backup, not coastal flooding. Even so, a cellar wall that stays damp for decades will deteriorate.

Older foundations also tend to have been repaired by several owners over the years, which means patches of different quality to sort through.

When Is a Crack in a Cellar Wall a Real Problem?

A thin crack that has not changed is usually cosmetic. A crack that keeps widening, runs diagonally, is wider at one end, or comes with a bowing wall or a sloping floor is a warning sign. Those cases may need a licensed engineer to assess the structure before repairs.

What you seeWhat it can meanWhat we do
Thin, stable crackOld shrinkage or minor movementSeal or patch and monitor
Widening diagonal crackSettlingRecommend an engineer, then repair as advised
Bowing cellar wallSoil and water pressureEngineer assessment, then structural work
Crumbling mortar in stone wallAge and moistureRepoint and patch the wall

Cracks near the front of a row house, around window openings or at the corners between two walls deserve extra attention. Those spots carry concentrated loads, and movement there tends to show up in the brick above as well as in the cellar below.

We do not promise underpinning outcomes. If your building needs structural work, we work with the engineer and handle the DOB filings.

What Permits Does Foundation Work in Boerum Hill Require?

Structural foundation work generally needs Department of Buildings filings and often an engineer's drawings. Simple crack sealing usually does not. Because the row houses here are in a historic district, exterior changes may also involve the Landmarks Preservation Commission. Confirm current rules with the city.

We handle the filings our jobs need. Foundation work also affects adjacent buildings on a row, so we check what has to be protected before digging starts.

Process

How Does a Boerum Hill Foundation Repair Move Forward?

It begins with an inspection to find the cause. If the problem looks structural, an engineer is brought in. Once the scope is set, we file permits, do the excavation or repair and finish the wall. Simple repairs take days and structural jobs take longer.

  1. Inspection

    We check the cracks, wall condition and water history.

  2. Assessment

    Engineer involved where the problem looks structural.

  3. Written price

    A clear scope showing what is repair and what is structural.

  4. Permits

    DOB filings and any landmark items handled.

  5. Repair

    Cracks sealed, walls repaired and drainage improved.

Do Nearby Construction and Old Footings Affect Row House Foundations?

They can. Boerum Hill has older row houses with stone and brick foundations beside newer buildings going up, and excavation or vibration next door sometimes coincides with new cracks in an older wall.

We cannot say what caused a crack without inspecting it. Fresh stair step cracks, a wall that is bowing and doors that no longer close are signs worth recording with photos and dates, which also helps if a neighbor or contractor needs to be involved.

Where a problem looks structural, we recommend a licensed engineer and confirm what the Department of Buildings needs. Work in the landmark district can also involve review, so check before starting.
