Foundation Repair for General Contractors: The Sub That Holds Your Schedule

Foundation repair for general contractors is really a schedule-and-trust problem. On a remodel, addition, or renovation, the slab or pier-and-beam usually has to be leveled or repaired before you can frame and finish — which puts the foundation sub squarely on your critical path. So the question isn't just "can they do the work," it's "will they give me a real date, hit it, coordinate the engineer and the permit, and hand me clean documentation and a warranty my client actually keeps." That's the sub we've built Motmot to be. We do the foundation scope, stay out of the rest of your job, and hand it back level, documented, and warrantied. We handle residential and light commercial. For a large or multi-story structure we coordinate with a structural engineer.

WHEN A GC CALLS A FOUNDATION SUB

The foundation is rarely the whole job — but it's usually on the critical path. Here's where we fit into yours.

Remodel / addition prep

The existing slab or pier-and-beam is out of level and has to be corrected before you tie in new framing.

Level base before finishes

Movement found mid-job

You open a wall or floor and find settling that has to be handled before the job can proceed.

Fast, scoped response

Pre-sale / pre-close repair

A client's inspection flagged the foundation and the deal needs it fixed and documented.

Documented + warrantied

Engineer-designed repair

There's a stamped design and you need a crew that builds to it and passes inspection.

Build to spec, pull permit

Level the base before the finishes go on

The reason a foundation problem is a GC's problem is timing. If the slab is out of level or a pier-and-beam is sagging, everything you build on top of it inherits the error — new framing that won't tie in square, finishes that telegraph the slope, a job that gets called back. So the foundation has to come first: we stop the movement with pressed piers, bring the floor back toward level, and hand you a flat, documented base to build on. On additions we make sure the new work and the existing structure end up on the same plane instead of fighting each other at the tie-in. Get the base right and the rest of your trades stop inheriting problems.

A date you can build a schedule on

The fastest way to blow a remodel is a sub who levels the floor late, because framing and finishes are stacked right behind it. So we treat the date as load-bearing: a real start and a real duration up front, not a hopeful one, sequenced around your other trades. If soil or access changes the timeline, you hear it early — not the morning your framers show up. We show up when we said we would and hand the section off when we said we would. That reliability is the entire reason a GC keeps one foundation sub on speed dial instead of re-bidding it every job.

Engineer and permit coordination handled

When a job needs a structural engineer — a design, a stamped letter, or sign-off on the repair — we coordinate with yours or bring in an independent one, and we build to that design. We work alongside independent engineers as a matter of routine, so an engineer's involvement is a normal step, not a source of friction. Where the jurisdiction requires a permit and inspection for the foundation work, we pull and pass it, or work under your permit if that's how your project is set up. The point is that you don't have to chase the AHJ paperwork on the foundation portion — it arrives in your file done.

Clean documentation and a warranty that transfers

What you hand your client at the end of a remodel is partly paperwork, and the foundation portion should make that easier, not harder. We deliver a clean package — signed scope, pier installation log with locations and depths, before-and-after elevations, engineer's letter when there was one, permit sign-off, and the written warranty — all documented the way our foundation documents guide lays out. And the workmanship warranty is tied to the structure and transfers to your client, and to the next owner on resale, with a short form. So the foundation work under your finished job carries a warranty your client actually holds — a selling point for the GC, not a loose end.

The methods we bring to your job

Most of what a GC needs from a foundation sub draws on the same core systems, matched to what the building is doing:

Slab foundation repair

Pressed steel, concrete, or hybrid piers to level a slab before you frame and finish over it.

Pier & beam repair

Leveling and support for pier-and-beam homes — a common find on remodels and additions.

Under-slab tunneling

Access to plumbing or interior piers from outside — no breaking the slab your finishes go on.

Drainage correction

Fixing the water that drives the movement, so the repair holds under the work you build on it.

We stay in our lane

Here's the part a GC actually values: we do foundation work and nothing else. We're not angling to become your framer or your remodeler, we don't upsell your client on work that isn't foundation, and we don't wander into your scope. We do the foundation piece, hand off a level and documented base, provide our certificate of insurance, and get out of your way. For the honest limits — Motmot handles residential and light commercial, one-to-two-story structures on standard slab or pier-and-beam, and coordinates with or brings in a structural engineer for anything larger or multi-story — that's the same guardrail we hold on every job. The inspection tells you plainly whether your building is in our lane before anything is scoped.

What the GC gets, in one place

WHAT A GC GETS FROM US AS A SUB

A firm date and duration up front — our part sits on the critical path and we treat it that way
A defined foundation scope and price, sequenced around your other trades
Engineer coordination — build to the stamped design, or bring in an independent engineer
Permit and inspection handled where the jurisdiction requires it, or work under your permit
A clean documentation package: scope, pier log, elevations, and sign-offs for your project file
A workmanship warranty that transfers to your client — and the next owner on resale

Cost, second opinions, and where we work

When you're pricing a job for a client, the foundation repair cost guide walks the real drivers so your line item is grounded, and the inspection turns it into a firm number for the building. If a client came to you already holding a foundation quote that feels heavy, the free second opinion re-measures and reads the other scope line by line — protecting your client protects your relationship with them. Under-slab plumbing surprises on a remodel have their own fast lane: we tunnel access from outside so you don't break finished floors. Motmot covers the full I-35 corridor — San Antonio, New Braunfels, San Marcos, Kyle, Buda, Austin, and Georgetown — from offices in San Antonio and San Marcos.

Common questions

General contractor questions, answered straight.

Do you subcontract to general contractors?

Yes — a good share of our work is as the foundation sub on a GC's or builder's project. On a remodel, addition, or renovation where the slab or pier-and-beam has to be leveled or repaired before you frame and finish, we do the foundation scope, hand off a level, documented base, and stay out of the rest of your job. We carry our own insurance, provide a certificate on request, and work inside your schedule and your paperwork. Foundation only — we don't wander into your scope.

Can you hit my schedule?

That's the whole reason a GC keeps a reliable foundation sub. We give you a real date and a real duration up front, not a hopeful one, because our part sits on the critical path — framing and finishes wait on it. We sequence around your other trades, tell you early if soil or access changes the timeline, and show up when we said we would. The fastest way to blow a remodel schedule is a sub who levels the floor late; we're built not to be that sub.

Do you handle engineer and permit coordination?

Yes. When a job needs a structural engineer — a design, a stamped letter, or sign-off on the repair — we coordinate with yours or bring in an independent one, and we build to that design. Where the local jurisdiction requires a permit and inspection for the foundation work, we pull and pass it, or work under your permit if that's how your project is set up. You get the documentation that keeps the AHJ and your client's lender satisfied without having to chase it.

Does the warranty transfer to my client?

Yes. Our workmanship warranty is tied to the structure and transfers to your client — and, on a resale, to the next owner — with a short form and a copy of the documentation. So when you hand over a finished remodel or addition, the foundation work under it carries a transferable warranty your client actually holds, not a promise that ends when the job closes. That's a selling point for the GC, not a liability.

What size and type of buildings do you take on?

Residential and light commercial — one-to-two-story homes and small commercial or institutional buildings on standard slab or pier-and-beam foundations, using pressed steel, concrete, and hybrid piers, slab and floor leveling, under-slab tunneling, and drainage correction. For a large or multi-story structure, or anything that needs a stamped structural design, we coordinate with or bring in a structural engineer rather than overpromise. Tell us the building at the inspection and we'll tell you straight whether it's in our lane.
