Home-services pros in San Antonio, TX

San Antonio sits on Edwards Plateau limestone with expansive Blackland Prairie clay soil overlay across much of Bexar County. The combination of high-shrink-swell clay (the most movement-prone soil in Texas alongside parts of DFW), the drought-flood cycle (multi-month dry periods followed by intense rain events), and slab-on-grade construction across nearly all post-1960 homes produces predictable foundation movement on most San Antonio properties.

Foundation movement signs: stair-step cracks in brick or block at corners, cracks at corners of windows and doors, doors that suddenly stick or swing open, separation between baseboard and floor, sloping floors measurable with a level, gaps between trim and ceiling. Some movement is normal in San Antonio homes — a totally crack-free 50-year-old house on Bexar County clay is unusual. The diagnostic for intervention is whether movement is active (currently progressing) or stable (settled into a long-standing pattern), and whether it correlates with documented water-source issues.

The two main San Antonio foundation remediation approaches: pressed concrete piers (drilled under the slab to deep stable soil, lifting and stabilizing the perimeter) and helical piers (steel piers screwed deep into stable soil layer, common for severely movement-prone areas). Drilled bell-bottom piers are also used. Per-pier scope depends on depth and access; full perimeter projects typically use 15-30 piers.

Watering — yes, you read that right — is one of the most-requested foundation maintenance recommendations in San Antonio. Soaker hose programs around the foundation perimeter during drought maintain consistent soil moisture and prevent the worst clay-shrink movement. The Texas A&M AgriLife Extension publishes specific guidance on foundation watering for South Texas homes. Many "foundation problems" can be partially mitigated with consistent watering before they require pier work.

When to involve a structural engineer: visible foundation movement, sloping floors more than 1 inch over 20 feet, recurring movement that doesn't respond to watering, or before any major addition. The engineer's written assessment scopes the actual work needed and provides documentation insurance carriers and future buyers will look for.

CPS Energy is the dominant electric utility in Bexar County — one of the largest municipal electric utilities in the country. CPS Energy's solar and battery rebate programs are among the most homeowner-favorable in Texas. The Solar Rebate program pays per-watt incentives for residential solar installs (program details change annually — verify current amounts at quote time). The Battery Saver program adds incentives for residential battery storage paired with solar.

Federal IRA 30% tax credit applies to both solar and battery components. The combined CPS Energy + IRA stack on a residential solar+battery install in San Antonio is one of the better incentive landscapes in the country, often resulting in 5-7 year simple payback for properly-sized systems.

What shapes solar economics in San Antonio: roof orientation (south-facing dominant; east/west moderate; north-facing rarely worth it), roof condition (most installers won't install on roofs with less than 10 years of remaining life — re-installing solar after a roof replacement adds significant cost), and electricity usage pattern. Households with high cooling loads in summer benefit most because solar production aligns with cooling demand.

What to ask a solar contractor: NABCEP certification status, specific equipment proposed (Tier-1 panels, microinverters or string inverters, battery brand if applicable), warranty terms (panel performance, microinverter, battery, workmanship — often four separate warranties), production estimate for your specific roof using PVWatts or similar tool, and CPS Energy rebate filing experience.

San Antonio has growing EV adoption, and Level 2 home charger installs are routine residential electrical projects. Most San Antonio homes built post-2000 have 200A panels with available breaker space; pre-2000 homes often have 100A or 150A panels needing upgrade before adding a 50A circuit (40A continuous draw) for the EV charger.

CPS Energy time-of-use rate options can shift EV charging operating cost — verify current programs before assuming standard residential rates. Some EV charger models (particularly hardwired ones) integrate with utility programs for time-of-use scheduling.

Hardwired vs plug-in: hardwired installs are cleaner but tied to that specific charger; plug-in installs (NEMA 14-50) are more flexible and can dual-purpose for RV power. Plug-in installs require GFCI breakers per current NEC code.

For homes scheduling solar + EV charger together: pre-wiring during the solar install for future EV charger is significantly cheaper than retrofitting later. CPS Energy may offer combined rebates for the bundled install — verify current programs.

San Antonio's climate is cooling-dominated. Summer design temperatures run roughly 100°F+ with high humidity; winter design temperatures around 25-28°F. The cooling load dominates — most existing San Antonio homes have oversized cooling and undersized heat. When converting to heat pumps (gaining popularity given electrification trends and CPS Energy electric rates), proper Manual J load calculation matters because sizing based on existing equipment usually produces oversized installs that short-cycle and fail to dehumidify.

Ductwork sizing matters in older San Antonio homes (1960s-1990s). Many have ducts sized for cooling-only systems; heat-pump conversions may need duct upgrades for proper heating airflow. A real load calculation identifies this; quick walk-through quotes often miss it.

CPS Energy HVAC rebates change annually. Federal IRA 25C credit applies to qualifying heat-pump installs. Combined rebates can be substantial — verify both at quote time so the contractor sizes the equipment to maximize the stack.
