Thermal sits on the flat floor of the Coachella Valley, on what was once the bed of ancient Lake Cahuilla. That geological history matters for anyone doing masonry or foundation work here. The sandy, alkaline soil left behind by that ancient lake is prone to shifting when moisture levels change - and in an agricultural community surrounded by irrigation canals and date palm farms, moisture levels in the ground do change, sometimes significantly, across seasons. Footings and slabs that are not designed with that soil movement in mind develop cracks within a few years, and block walls built on shallow footings gradually lean and settle. This is not a problem unique to older homes - it affects new installations too if the contractor is not familiar with valley floor soil conditions.

Add to that the climate reality: Thermal regularly sees summer highs above 110 degrees Fahrenheit, over 300 sunny days a year, and spring windstorms that carry fine sand capable of scouring exterior masonry surfaces. The UV exposure alone degrades surface sealers and caulking faster here than almost anywhere else in California. Most of the housing stock in Thermal was built in the mid-20th century and has not had major renovation, which means many properties have masonry features - perimeter block walls, patio pads, walkways, and stucco exteriors - that are overdue for a serious assessment.

Thermal is a small, rural unincorporated community in Riverside County, situated in the southern Coachella Valley about 30 miles southeast of Palm Springs. The community has a resident population of approximately 3,000 to 4,000 people, though the area has a larger seasonal presence tied to agricultural work in the surrounding date palm, grape, and citrus operations that make this part of the valley one of the most productive farming regions in California. Jacqueline Cochran Regional Airport, located just outside the community, serves as both a general aviation facility and a landmark that most Thermal residents use as a reference point for the area.

The housing in Thermal is predominantly modest single-family homes and manufactured housing on flat lots, most built in the mid-20th century and sharing the stucco-and-block construction style common throughout the Coachella Valley. Highway 111 is the main road through the community, running parallel to the Salton Sea a few miles to the east. Neighboring Coachella to the north is the closest incorporated city with a full range of municipal services, while Mecca to the south is the other major unincorporated community in this part of the valley. We serve both communities as part of our regular coverage area.
