Houston Pool Service & Repair — Cleaning, Repairs & Equipment

Most weekly pool service in the Houston area runs somewhere in the range of about $120 to $250 a month, depending on the size of your pool, whether it’s chlorine or saltwater, how much tree cover and debris it deals with, and exactly what the plan includes. A basic "chemicals only" visit sits at the low end, while full-service plans that add brushing, netting, emptying baskets, backwashing the filter, and inspecting equipment cost more. Pools under heavy oak canopy or near construction usually need more attention and land higher. Because our long swim season means your pool is running almost year-round, consistent weekly care is genuinely cheaper than the algae blooms, stained plaster, and burned-out pumps that come from letting it slide. Our partners will quote you a flat monthly rate after seeing the pool, so there are no surprises.

A green pool is algae, and the fix is a process rather than a single dose. First the water is tested and balanced, then it’s shock-chlorinated to a high level to kill the algae — often several pounds of shock for a badly neglected pool. The pump has to run continuously (24 hours or more) to circulate the chemicals, the walls and floor get brushed to knock algae loose, and an algaecide may be added. As the algae dies the water usually turns cloudy blue-gray, then clears over a few days of running the filter and cleaning or backwashing it repeatedly. In Houston’s heat a pool can go from clear to green in just a couple of days once chlorine drops, so severe cases sometimes need a chlorine wash or acid wash instead of chasing it with chemicals. Our partners can clear most green pools in under a week and, just as importantly, sort out why it happened so it doesn’t come right back.

For most Houston pools, weekly service is the right cadence, and it’s what we recommend. Our long, hot swim season means chlorine burns off fast, algae grows aggressively, and pools see heavy use for eight or nine months of the year — so water chemistry can drift out of safe range in just a few days. A weekly visit keeps sanitizer and pH in check, catches equipment problems early, and keeps the water balanced so it isn’t etching plaster or corroding metal. Beyond the weekly chemistry, filters should be cleaned periodically (monthly to quarterly depending on type and load), and the full equipment set — pump, heater, automation — deserves a closer inspection at least once a year. If you have a saltwater pool the cell should also be checked and cleaned on a regular schedule. You can do it yourself, but many Houston owners find weekly professional service is worth it just for reliably clear, safe water.

Both are actually chlorine pools — the difference is how the chlorine is delivered. A traditional pool needs chlorine added manually (tablets, liquid, or a floater), while a saltwater pool has a salt cell that generates chlorine continuously from dissolved salt. Saltwater pools tend to feel softer on skin and eyes, keep more stable chlorine levels, and require less hands-on dosing, which many Houston families prefer. The trade-offs: the initial salt system costs more up front, the salt cell is a wear item that needs cleaning and eventual replacement every 3 to 7 years, and the salt can be harder on certain deck materials, stone, and metal fixtures over time. Chlorine pools are cheaper to set up and simpler to fix, but demand more frequent manual dosing in our heat. Neither is "no maintenance" — both still need balancing, brushing, and filtration. Our partners install and service both and can walk you through which fits your budget and how you use the pool.

There are a handful of common culprits, and they range from trivial to serious. If the pump won’t turn on at all, it’s often a tripped breaker or GFCI, a bad timer, or a failed capacitor — the capacitor is an inexpensive part that fails frequently in our heat and causes a humming pump that won’t start. If the pump runs but moves little or no water, the usual suspects are a clogged basket, a dirty or clogged filter, a closed valve, or an air leak on the suction side that lets the pump lose its prime. A pump that’s loud, screeching, or vibrating usually has worn bearings, and one that’s leaking at the seal or shutting itself off may be overheating. Houston pumps also simply wear out from running so many hours a year. Some of this is DIY-checkable (clear the basket, confirm valves are open, reset the breaker), but electrical and motor issues should be handled by a pro. Our partners diagnose the exact cause and repair or replace the pump — often upgrading you to an energy-efficient variable-speed model that pays for itself on your electric bill.

The clearest sign is water loss beyond normal evaporation. In a Houston summer a pool can lose as much as a quarter to a half inch a day just to evaporation, so a good test is the bucket test: set a filled bucket on a step, mark the water levels inside and out, and compare after a day or two — if the pool drops noticeably faster than the bucket, you likely have a leak. Other red flags include the auto-fill running constantly, soggy or unusually green patches around the pool, cracks in the deck or plaster, air bubbles coming from the return jets, a drop in water level that stops at a particular spot (pointing to a leak at that fitting or light), and rising water bills. Because our expansive clay soil shifts so much, leaks in underground plumbing and at fittings are common here. Leaks waste water, undermine the deck and soil, and can damage equipment, so they’re worth chasing down. Our partners perform pressure testing and dye testing to pinpoint the source before any digging.
