About Allen properties

Allen’s population went from 8,314 in 1980 to 18,309 in 1990, 43,554 in 2000, 84,246 in 2010 and 104,627 in 2020, according to the US Census Bureau decennial counts reported on Wikipedia, and the ACS 2024 1-year estimate via Census Reporter puts it at 113,761 now. Wikipedia lists the city as incorporated in 1953, covering 26.48 square miles about 20 miles north of downtown Dallas. Housing followed the same curve. The 2020 Census counted 36,962 housing units with a 69.8 percent owner-occupied rate, and the ACS 2024 1-year estimate, table B25003, shows 40,163 occupied units with 26,632, about 66 percent, owner occupied. The doubling between 1990 and 2000, and the near doubling again by 2020, gives Allen two generations of slabs: one poured in the 1990s that is approaching 30 and one poured after 2000 that sits at the median. They have had different numbers of wet-dry cycles, and the estimate should note which generation you own.

Foundation services we handle in Allen

Most Allen requests are for slab repair on a 2000s-era house where one wing has settled. Where the drop is small and the concrete is a driveway, patio or garage floor rather than the living space, concrete leveling lifts it with foam or grout pumped through small holes. A brick crack that runs in a stair-step up a corner is usually the first thing an Allen owner notices, and foundation crack repair covers both the seal and the check for movement behind it. When doors across the house stick at the same time, house leveling is the likely answer. If your Allen home sits on a raised floor instead of a slab, pier and beam foundation repair handles the sills, beams and posts beneath it. Water pooling at the slab edge after a May storm is a foundation drainage problem before it becomes a pier problem. Start with a foundation inspection if you want the facts before the fix, and see the foundation repair page for how the contractor is chosen and what the warranty covers.

Why the local detail matters in Allen

Texas A&M AgriLife soil scientist Dr. Jake Mowrer, quoted by FOX 7 Austin in August 2022, explains the mechanism in one line: Texas vertisols swell when they get wet and shrink when they get dry because water slips between microscopic clay layers. The USDA NRCS Houston Black fact sheet adds the detail that matters for timing. Water enters this clay rapidly when it is dry and cracked and very slowly when it is moist, so the first big rain after a drought is when an Allen slab moves the most. The summer of 2023 brought only 1.25 inches of rain to DFW Airport from June through August, per the National Weather Service in Fort Worth, and a dry stretch like that is what opens cracks the following fall.

The Texas Section of ASCE defines expansive clay as soil with a plasticity index above 15 or a potential volume change above 1 percent, and says foundations on those sites should be engineered by a Texas-licensed engineer. Permits are handled city by city. Neighboring McKinney, for comparison, requires a permit for any leveling, pier or shimming work and closes it only after the engineer’s final report is uploaded, per the City of McKinney Building Inspections guidelines. The contractor confirms Allen’s current requirements with the city before the first pier goes in, and the engineer’s letter comes with the job regardless.

Foundation repair Allen TX homeowners ask about most

Three questions come up on nearly every Allen call. Will the piers crack my slab? A pier lifts from underneath at a point the engineer picks, and the lift is done in small steps with the crew watching the brick, so a controlled lift is far gentler than the clay has been. Do I have to clear out? The work happens at the slab edge or beneath it, not in the living space, and the estimator will say in advance if a room needs to be emptied for an interior pier. Will it happen again? The piers rest on soil below the zone that wets and dries, so the supported section stops riding the clay, and the written warranty covers the piers.
