Foundation Repair in Sunnyside, Queens

What Foundation Problems Show Up in Sunnyside?

Older buildings here show hairline cracks, stair step cracks in brick, damp patches on basement walls and doors that stick. Most cracks are minor and come from age. A few signal movement that needs a closer look before any repair.

Sunnyside has many pre war brick buildings, including attached two family homes and apartment buildings. Foundations that old have carried weight for a century, and they shift a little as the ground and the building change.

Trees add to this on residential blocks. Roots can pull moisture from soil near a wall, and a dry spell followed by heavy rain can move the ground slightly.

We do not promise outcomes on structural problems. We look, explain what we see and tell you whether the repair is within our scope or needs an engineer.

How Do We Repair a Foundation?

The repair depends on the cause. We seal stable cracks, repair damaged masonry, restore parging and fix drainage that sends water toward the wall. For structural movement, a licensed engineer may need to design the fix first.

Stopping water is a big part of the job. Gutters, downspouts and the grade around the building decide how much water reaches the wall. Fixing those often prevents repeat damage.

Repairs to the wall itself include repointing, replacing loose block or brick, and rebuilding damaged sections. We match materials to the existing wall.

Is water in the basement a foundation problem?

Not always. Sunnyside is inland with no particular flood exposure beyond heavy rain sewer backups. A backup comes from the sewer line, and it needs a licensed plumber and possibly a backwater valve. Our basement waterproofing in Sunnyside page covers seepage through walls and floors.
