Serving Harlingen, TX and surrounding areas. (956) 506-1335
Sticking doors, cracked drywall, and uneven floors are signs your home is moving. We stabilize Harlingen slab foundations and give you a written warranty before we leave.
Foundation repair in Harlingen means stabilizing or lifting a concrete slab so the structure above it sits level again. Most jobs involve installing support piers along the perimeter or beneath the slab, with the majority of residential work completed in one to three days.
The Rio Grande Valley's highly expansive clay soil is the primary reason foundations move here. It swells after heavy rain and contracts during the long dry spells South Texas is known for, and that push-and-pull cycle puts constant stress on slabs - even relatively new ones. If you are also noticing issues with the masonry on your property, our chimney repair service addresses related structural concerns.
A large share of Harlingen homes were built between the 1950s and 1980s, when slab thickness and soil preparation standards were less rigorous than today. If your home is from that era, a proactive assessment is often worth the call - before visible symptoms become a larger problem.
Interior doors that drag on the floor or refuse to latch are often the first sign your home is shifting. In Harlingen, this typically appears after a dry summer when the clay soil contracts and pulls support away from parts of the slab. It is one of the most reliable early warnings.
Cracks running diagonally from door or window corners toward the ceiling are different from normal cosmetic hairline cracks. Watch for ones wider than a pencil tip, appearing in multiple rooms, or growing over time. In older Harlingen homes on thinner slabs, these can develop gradually over years.
Walk your home and check where walls meet the ceiling and where baseboards meet the floor. Gaps that were not there before - or that seem to be widening - suggest the structure is moving. This is especially worth checking after a prolonged dry period, which is common in the Valley during La Nina years.
A floor that slopes more than an inch or two over a ten-foot span is a sign that part of the slab has dropped. In Harlingen, this often shows up in perimeter rooms where the soil dries out faster than in the home's center. An unexplained rise in your water bill may also signal a slab leak contributing to uneven soil moisture.
We handle the full range of slab foundation repair work for Harlingen homeowners. The most common approach for settled or sunken sections is perimeter underpinning - driving steel or pressed concrete supports deep enough to reach stable soil, then carefully lifting the affected slab sections back toward level. For smaller voids beneath a slab, we also offer foam injection to fill gaps and re-support low areas without major excavation.
When foundation movement has stressed the surrounding masonry or caused issues with structural walls, we also provide foundation block wall installation to reinforce and restore those areas. Every job starts with a written assessment and ends with written warranty documentation so you know exactly what was done and what is covered.
Best for homes with significant settling along exterior walls where soil has contracted away from the slab edge.
Addresses drops or voids beneath the center of the slab that perimeter work alone cannot reach.
Fills gaps beneath a slab quickly and with minimal disruption - well suited to smaller sunken areas.
For homeowners who want ongoing confirmation that the repair is holding through seasonal soil changes.
Confirms no active slab leak is contributing to the foundation movement before repair work begins.
For homes where settling has cracked or displaced block stem walls or perimeter masonry.
The soil beneath most of Harlingen is classified as highly expansive clay. It swells significantly when it rains and shrinks back during dry spells - and South Texas experiences serious drought cycles that can last for years. During those stretches, the clay pulls away from foundation edges and creates voids that allow slabs to drop. Timing a repair during or just after a drought, rather than waiting, often prevents a manageable problem from becoming a much larger one. Homeowners in San Benito and Weslaco deal with the same soil conditions, and we work across the entire Valley with that local context in mind.
A second factor unique to this area is aging plumbing. Harlingen's underground water and sewer lines were largely installed in the same postwar construction era as the homes themselves. Slow leaks beneath slabs are a frequent contributor to uneven soil moisture and foundation movement here. Texas A&M AgriLife Extension has published guidance on foundation issues in Texas that confirms this relationship between soil conditions and slab behavior. A responsible contractor checks for active leaks before any repair begins.
We respond within 1 business day. The first call is short - we ask what you are seeing and schedule a free on-site visit. Most initial assessments take between 45 minutes and two hours depending on the size of your home.
Our crew walks through your home and around the exterior, measuring floor elevation at multiple points to map where the slab has moved. You get a clear written explanation and a written estimate before we ask you to commit to anything.
If the repair scope requires a City of Harlingen building permit, we handle the application - that is our responsibility, not yours. Once the permit is in hand, we schedule the crew, typically within one to three weeks.
The crew installs supports and carefully stabilizes or lifts the affected slab sections. Before we leave, we walk you through what was done, show you before-and-after elevation measurements, and hand you written warranty documentation.
We respond within 1 business day. No obligation, no pressure. After you submit, someone from our office will call to schedule a free on-site estimate.

Every job starts with a written scope and a written price. No surprise billing. Every completed repair comes with a written transferable warranty - which means it stays with the house if you sell it, a real advantage in the Rio Grande Valley's active real estate market.
We have been working on homes in and around Harlingen for years. We know the clay soil conditions, the housing stock, and the Cameron County permit process. When you call, you are talking to someone who works in this community - not a call center.
The South Texas clay soil is going to keep moving with the seasons. We use support depths and methods suited to Rio Grande Valley conditions so your repair holds through future wet seasons and drought cycles - not just until the next rain.
State licensing, written paperwork, and genuine local knowledge are the baseline for any contractor you should trust with your home's foundation. The Foundation Repair Association provides consumer resources that spell out exactly what to look for when comparing contractors - we are happy to be measured against those standards.
Foundation movement can stress chimney masonry and open cracks at the roofline - our chimney repair service addresses those issues directly.
