Underpinning adds support below your home to stop movement for good. ## When Duncanville Homes Need Foundation Underpinning Duncanville sits on heavy black clay soil that swells and shrinks with every rain and dry spell. That constant movement pushes and pulls at your foundation year after year. We see it most in older ranch homes near Duncanville Hills. Slabs were poured decades ago on soil that's moved a lot since then. Underpinning drives new supports below the foundation to reach stable soil or bedrock. [](https://en.wikipedia.org/wiki/Underpinning) This stops the shifting. Waiting only lets cracks grow wider and doors stick worse. Stair-step cracks in brick or gaps around windows mean the movement is already active. A small fix now beats a full slab replacement later. Sinking Slab Corners Stair-Step Brick Cracks Sticking Doors and Windows Uneven Floors Older Pier and Beam Homes Post-Storm Settlement Years fixing foundations across the Dallas-Fort Worth Metroplex since 1969. Estimates with a next-business-day response, no cost to find out what's wrong. Limited lifetime warranty backs every underpinning job we complete. 57 Free Lifetime One corner of your slab drops lower than the rest. Underpinning lifts and locks that corner in place. Cracks that climb up brick mortar joints mean the foundation below is losing support somewhere. Frames shift out of square when the slab under them tilts or drops even a little. A ball rolling on its own across your floor is a clear sign the foundation has moved. Many older Duncanville homes have wood piers that rot or shift over time and need reinforcement. Heavy spring rains and hail season can saturate soil fast, causing sudden shifts under your slab.

We pick the right pier type for your soil depth and home weight. Every plan is written out with pricing before we start. Our crew drives supports to stable soil and lifts the foundation where needed.

No hidden add-ons once the job is underway. Price depends on how many piers your home needs and how deep they must go to reach stable soil.

Financing is available if you'd rather spread out the cost. Foundation Underpinning Cost in Duncanville Typical price range $1,500 - $12,000+ Fair Pricing ## Foundation Underpinning Questions Here are answers to what Duncanville homeowners ask us most. ## Frequently Asked Questions **Q:** How much does foundation underpinning cost? A: Most jobs run between $1,500 and $12,000 or more depending on pier count and depth. We give a free estimate so you know the exact number before we start. Financing is available if needed. **Q:** How long does underpinning take? A: Most residential jobs take one to three days depending on how many piers your home needs. Larger homes or deeper soil conditions can add time. We'll give you a timeline during the free estimate. **Q:** Can I install underpinning myself? A: No, this is not a DIY project. Underpinning needs the right equipment and knowledge of soil depth to work safely. A mistake can cause more damage than the original problem. **Q:** How is underpinning different from mudjacking? A: Mudjacking lifts a slab by pumping material underneath it, which works for minor settling. Underpinning adds deep piers for homes with ongoing or serious foundation movement. We'll recommend the right fix after inspecting your home. **Q:** How urgent is foundation underpinning? A: The sooner you address movement, the less it costs to fix. Cracks widen and doors stick worse the longer you wait. Call now if you notice new cracks after a rainy season. **Q:** What are the signs I need underpinning? A: Look for stair-step cracks in brick, doors that stick, and uneven floors. Gaps around windows and separating trim are common too. Duncanville's clay soil makes these signs show up faster than in other areas. **Q:** Does underpinning come with a warranty? A: Yes, our underpinning work is backed by a limited lifetime warranty. That means you're covered long after the crew leaves. We've stood behind our work in Duncanville since 1969.
