Its quote should address drainage and confirm the city paperwork for the proposed work. The building application includes Remodeling and Concrete Slab categories and a Foundation inspection.

The permit and the inspection

Planning & Development issues building permits and runs inspections. The same department handles code enforcement for building repairs. The application requires attached drawings. Ask the company to include a clear drawing of its proposed work.

Ask the company to identify any required inspections and who will request them. The posted development code requires a permit for structural alterations. Have the company confirm whether that rule covers its repair and include any permit fee in the written price.

Clay and drought in Jackson County

The USDA survey maps 523,149 acres in Jackson County. Its shrink-swell ratings describe how much soil swells when wet and shrinks as it dries. The share rated high or very high is 16.4% using the surface layer alone, compared with 28.4% when deeper layers are included. Hollister silty clay loam is the biggest high-rated mapped soil, covering about 74,262 acres. Its estimated swelling measure is 8.9%; Tillman clay loam covers about 22,111 acres at 6.6%.

Dry spells matter here too. The draft county hazard plan says dry, cracking soil can cause water lines to break during drought. The ASCE Geo-Institute’s homeowner guide adds that leaking water or sewer lines can make one part of a foundation move. It recommends even soil moisture next to and under the house to reduce movement. County soil estimates are not a test of your lot; ask the company to assess conditions around your foundation.

Older Altus houses

The Census estimates 1,103 Altus housing units were built in 2000 or later. For an older property, bring past repair papers and inspection reports to the assessment. Ask the company to distinguish earlier movement from changes happening now. If two bids disagree or the damage is extensive, consider an independent structural engineer’s review.

Who does the work

The Altus contractor application lists $250 for a new city license and $50 for renewal, as of October 2026. It asks for a state license and ties expiration to that license. Have the company explain which city requirements apply to its repair work. If it recommends fixing a leaking pipe, ask for the state-licensed plumber’s name in the quote.

Flood-zone lots

The draft hazard plan lists Altus as a National Flood Insurance Program participant. The development code calls for a separate floodplain permit for construction or development in flood hazard areas. It also requires substantially improved homes there to have the lowest floor at least 1 ft above base flood elevation. The city’s online GIS map shows flood zones by lot. Ask the company whether its repair needs that review.

The foundation warning signs page sorts common cracks and other signs by urgency. Altus homeowners looking at a shelter can also read the Altus storm shelter page.

Questions to ask a repair company

For a major repair, or if the problem is unclear, will a licensed engineer review the plan?
Engineering guidelines describe an engineer's evaluation as the way to tell cosmetic cracks from structural damage. ASCE Texas Section guidelines (2022)
What is causing the movement, and what will be done about the water?
On shrink–swell clay, keeping soil moisture even around and under the foundation is the main way to reduce movement, so drainage and leaks matter as much as the repair. ASCE Geo-Institute, Living With Shrink/Swell Soils (2022)
Will the plumbing be tested after lifting, and who pays if a leak is found?
Engineering guidelines call for leak tests of water and sewer lines after a foundation is lifted. ASCE Texas Section guidelines (2022)
Will you measure floor levels before and after the repair?
Engineering guidelines call for an elevation survey after the work, which gives you a before-and-after record. ASCE Texas Section guidelines (2022)
Is the warranty in writing, what does it exclude, and does it transfer if I sell the house?
