How to Hire a Foundation Repair Contractor in New Orleans, LA

Start with the diagnosis, not the sales pitch

A trustworthy New Orleans contractor takes floor-level readings across the whole house, checks individual pier condition under a raised home, or measures slab elevation at multiple points on a slab home, rather than quoting a flat package sight unseen. Ask whether they distinguish between normal seasonal clay movement and ongoing regional subsidence, since the two call for different long-term approaches.

In raised pier neighborhoods like Uptown, Bywater, Marigny or Carrollton, ask whether the inspector will check brick pier condition and cypress sill health for termite damage as part of the same visit, since settlement and wood damage frequently occur together in this climate.

A serious inspector will also walk the crawlspace or under-house area with a flashlight looking for standing water, mud tubes climbing pier faces, or soft, spongy sill wood, since these are the telltale signs of Formosan termite activity that a purely visual floor-level check from inside the house can miss entirely. Ask whether the company photographs each pier and sill section during the walkthrough, since a written report with photos gives you something concrete to compare against a second opinion, and it also documents baseline condition in case a dispute over scope arises later in the project.

Verify their LSLBC license or Home Improvement Registration

Ask for the company's Louisiana State Licensing Board for Contractors number and verify it through the LSLBC's online search. Projects over $75,000 require a full Residential Contractor license with tested trade and business/law exams; projects between $7,500 and $75,000 only require a Home Improvement Registration, a lighter business-and-insurance filing.

If your project involves remediating standing water or long-term humidity damage under the house, ask whether the contractor separately holds Louisiana's Mold Remediation registration, which is required once the affected area passes the state's minimum threshold.

Louisiana's LSLBC search tool lets you check not just whether a license or Home Improvement Registration is active, but also whether any complaints or disciplinary actions are on file, so take the few minutes to look up the full record rather than just confirming the number exists. Because Home Improvement Registration is a lighter filing than the tested Residential Contractor license, ask directly which category your contractor holds and whether your project's total contract value, including any sill repair, drainage work or termite remediation bundled into the same job, might push it over the $75,000 threshold that requires the full license instead.

Ask about historic district review before you sign

If your address falls within a New Orleans historic district, which includes large parts of the French Quarter, Garden District, Uptown, Bywater, Marigny and Treme, ask whether the proposed work will visibly change the house's elevation or exterior foundation appearance, since that typically triggers Certificate of Appropriateness review by the Historic District Landmarks Commission or, in the French Quarter, the Vieux Carre Commission.

Confirm who is responsible for submitting that historic review application and how long the contractor expects it to take, since skipping this step is a common source of stalled permits and after-the-fact city violations in protected neighborhoods.

Even homeowners who are confident their block isn't historic should double check, since HDLC districts extend well beyond the French Quarter into large sections of Uptown, the Garden District, Esplanade Ridge, Bywater, Marigny and Treme, and boundaries can run mid-block in ways that surprise longtime residents. A contractor who has pulled Certificates of Appropriateness before can usually estimate review turnaround fairly accurately, often a few weeks for straightforward pier or sill work that doesn't change visible elevation, versus a longer timeline for anything that alters how the house sits relative to the street.

Get three written quotes and compare scope, not just price

Get three written quotes for anything beyond isolated pier shimming. A complete quote lists pier, piling or shim count with a diagram, whether the Department of Safety and Permits permit and any historic review are included, sill and termite repair as a line item if needed, and warranty terms including transferability if you sell the home.

Be skeptical of a leveling quote that's dramatically lower than the others without explanation, since that often means fewer pilings or shims than your soil actually requires, or skipped termite and sill repair that resurfaces within a year or two.

Confirm who pulls the city permit and how

Structural leveling, pier and piling work require a building permit filed through the Department of Safety and Permits' One Stop App portal. Ask the contractor directly who is filing, under what license or registration number, and for the permit number once it's issued.

If a contractor tells you house leveling or piling work doesn't need a permit, treat that as a red flag and confirm independently with the Department of Safety and Permits before signing anything.

Keep in mind that the One Stop App also lets you look up permit history on a property yourself, which is a useful way to confirm that a previous owner's foundation work, or a neighbor's piling project you're using as a reference, was actually permitted and inspected rather than done quietly without city sign-off. An unpermitted prior repair can complicate your own project if the Department of Safety and Permits requires it to be brought up to code before approving new work.

Understand why raised-house and slab-home pricing look so different

Shimming individual brick or cypress piers under a raised house is priced per pier and is generally far cheaper per unit than driving helical or pressed pilings under a slab, because slab homes typically need fewer, deeper, more heavily engineered support points to lift and stabilize the entire foundation at once.

If two quotes for what sounds like a similar-sized job come in wildly different, ask whether one company is quoting a full piling system when your raised pier house actually only needs targeted pier shimming and sill repair, or vice versa.

New Orleans homeowners who take the time to verify credentials and ask pointed diagnostic questions upfront consistently report fewer surprises during the actual repair, since a contractor who is confident in their licensing and their diagnosis is usually also transparent about scope and timeline.

Don't hesitate to ask a prospective contractor for two or three recent local references in a neighborhood similar to yours, whether that's a raised pier house in Marigny or a slab home in New Orleans East, since a company with genuine local experience should have no trouble providing them.
