Settlement Repair Problems We Fix in Port Washington

Long Island's unique geology — dense clay soils, high water tables, and freeze-thaw cycles — creates conditions that stress foundations year-round. Ignoring early signs leads to structural damage that's far more expensive to fix.

  • Uneven floors (visible with a level — more than 1" drop in 10 ft is significant)
  • Sticking doors and windows from frame racking
  • Diagonal cracks originating from corners of windows/doors
  • Organic subsoil compression in former farm field developments

The good news: most Long Island foundation problems are repairable — and the sooner you address them, the less it costs. A hairline crack caught early costs a fraction of what a bowing wall or failed waterproofing repair runs.

Why Port Washington Homeowners Choose Us

Port Washington's steep drumlins and glacial bluffs create dramatic slope instability that puts below-grade walls in hillside homes under constant lateral earth pressure.

Port Washington homeowners call us for foundation settlement repair more than almost any other service — and the reason is Nassau County's blend of clay soils and high water tables. Long Island's former farm fields (Melville, Hauppauge, Commack) have organic subsoils that compress as homes age. Coastal fill areas compound this with sandy soils that offer poor bearing capacity. Helical piers are preferred over push piers in coastal conditions — they screw into stable soil without needing bedrock.

  • I was quoted $28,000 by two other companies. Long Island Foundation Pros looked at the same wall and told me I needed carbon fiber straps — $6,800. My basement has been dry for 18 months. I wish I'd called them first.

  • My 1962 ranch in Levittown had water coming in every spring for as long as I can remember. They installed an interior drain system and I haven't touched a wet-vac since. Honest guys who showed up when they said they would.

  • As someone buying a house on the North Shore, I needed a foundation assessment before closing. They came out the next day, gave me a full written report, and told me exactly what I was dealing with. No upsell, just facts. I bought the house and had them fix it.
