Clinton’s permit forms

The Pre-Application is for work that has not started yet. It lists Repair/Remodel and Excavation among the types of work. You sign that nothing will start until the application is approved, the permit is issued and all fees are paid. If you do not apply in person, the signature must be notarized. The form asks for:

a description of the work on a plot plan with the buildings on the lot
the estimated cost
the contractor and the person in charge of the work
subcontractors for the major trades, such as a plumber

If no permit is issued, the application expires after 90 days. Have the company confirm whether its repair needs a permit and include the category and fee in the written quote.

The Post-Application is for work already underway without a permit. Signing it commits the applicant to stopping until the permit is approved and paid. Ask the company to resolve its filing before setting the repair date.

What the soil survey shows

Custer County’s USDA soil survey covers 641,626 mapped acres. It rates none of them high or very high for shrink-swell, meaning soil that swells a lot when wet and shrinks as it dries. About 45% of the county is rated moderate and about 54% low. The USDA soil handbook says moderate shrink-swell can still damage buildings.

Ask the company to assess moisture around the foundation along with the damage. The ASCE Geo-Institute’s homeowner guide describes several sources of uneven moisture:

leaking water or sewer lines, which can move one part of the foundation
roof runoff and water ponding next to the house
tree roots that dry out the soil near or under the house

The guide recommends keeping moisture even beside and beneath the foundation. County averages do not measure your lot’s soil, so have the company explain what it finds at your house.

Clinton’s older houses

An estimated 71% of Clinton’s housing units predate 1980, according to the Census. For an older house, gather earlier repair records and dated photos of cracks before the visit. Ask the company to explain which signs suggest current movement. When bids conflict or damage is extensive, an independent structural engineer can review the recommendations.

Inspections and the crew

Clinton’s inspection menu names Foundation alongside framing and other project stages. Requests made during working hours are scheduled for the next workday. Ask which inspections the repair needs and have the company name the person responsible for requesting them.

The city contractor application asks for a state license and lists technicians, apprentices and journeymen. Have the repair company explain the city licensing requirements for its job. A plumber repairing a leaking line needs the relevant state license, so ask who will handle that part of the work.

The building form includes a floodplain review and a place for the Flood Plain Manager’s signature. If your lot is in a flood zone, have the company explain any effect on the repair. The foundation warning signs page helps you record symptoms before the visit. For shelter planning at the same property, see the Clinton 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?

What is causing the movement, and what will be done about the water?

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)
