Acid wash pool cost in San Angelo — why it matters
If your pool has stubborn stains, rough plaster, heavy scaling or has gone green and traditional treatments didn’t get it back to usable condition, you may be looking up “acid wash pool cost” in San Angelo. An acid wash can restore plaster finish in certain cases, but it’s a disruptive service and not always the right first step. Below we break down typical costs, what affects price, and how local Concho Valley Pool handles acid washes safely for homeowners across San Angelo and surrounding areas like Christoval, Grape Creek, Wall and Mertzon.
Typical acid wash pool cost — ballpark ranges
Costs vary by pool size, how badly the surface is affected, access, and whether surrounding decking needs protection. In San Angelo, a simple residential acid wash often falls in a general range of a few hundred to a low four-figure amount. Deeper repairs, extensive scaling, or pools needing plaster replacement will be higher. Always get an on-site assessment because photos and square footage estimates only tell part of the story.
Quick Checklist — what to inspect before you call
- Is the plaster rough or etched to the touch, not just discolored?
- Are there large chips, exposed aggregate, or peeling areas?
- Is the staining organic (algae) or mineral (calcium, metals)?
- Can the crew get equipment and water disposal access to your yard?
- Do you have recent water chemistry history (stabilizer, calcium hardness)?
What affects price
- Pool size and shape — more surface area = more labor and materials.
- Severity of damage — light staining vs full plaster resurfacing.
- Prep and cleanup — protecting decking, fencing, and proper waste disposal.
- Local code or HOA requirements for handling acid and wastewater.
When to DIY vs When to Call Us
DIY: If you have light staining from algae or metals, start with targeted chemical treatments, metal sequestrants, brushing, and a thorough vacuuming. For small, cosmetic etching you may try a gentle pumice rub meant for pool surfaces—but be cautious.
Call a pro: If the surface is pitted, heavily scaled, has large chips, or if you’re unsure whether the stain is mineral vs organic. Acid wash involves hazardous chemicals, precise dilution, and safe disposal of rinse water. Concho Valley Pool is family-owned, has served San Angelo for 13+ years, and has the experience and safety processes to decide if an acid wash is the correct solution or if alternatives (spot plaster repair, grinding, or full replaster) make more sense.
Service proof — safety & accuracy
Certified Pool Operator (CPO®): Our technicians include CPO®-trained staff and we are commercial-ready for apartments, HOAs, hotels and public pools. That experience matters when you’re handling acids around decking, drains and equipment.
State-of-the-art mobile water testing: We use lab-grade, on-site digital water testing so we can evaluate alkalinity, hardness and metals immediately at your pool. Testing on-site is more convenient and reduces guesswork compared with store kits that sit in a car for hours.
We’ll always outline alternatives and estimated costs after seeing the pool. That prevents surprise charges and ensures the chosen repair is cost-effective for the life of the pool.
Practical tips to lower cost
- Keep regular chemical balance and routine brushing to prevent stains in the first place.
- Provide clear access to water and power to reduce labor time.
- Combine services (filter service, vacuuming, chemical balancing) when scheduling — we often save you trips and time.
