Algae bloom after a hot week. A cracked tile you found over the weekend. A pump that's whining louder than it should. South Valley pool owners deal with all of it, and the company you hire for weekly service is the same company that'll tell you - honestly or not - whether that odd noise means a $400 seal or a $3,800 pump replacement. The quality of that relationship matters.
We pulled listings from Google Maps, Yelp, and Angi, verified licenses where applicable, and prioritized pool service companies actually based in the South Valley. Here are three worth calling for weekly service, repairs, or both.
K & J Pool Service
Address: 1565 Edmundson Ct, Morgan Hill, CA 95037
Service area: Morgan Hill, Gilroy, Hollister, and surrounding South County
In business since: 1992
ð Call (408) 779-8589 · ð Directions
K & J has been servicing South Valley pools since 1992. They do weekly cleaning, chemical balancing, equipment repair, and installation. They're the company you'll see at half the pools on your block - volume means they know the equipment brands, the failure patterns, and the Morgan Hill-specific water chemistry issues.
Why locals pick them: Decades of local experience and a route system that means your pool tech is usually the same person week over week. Reviewers mention consistent service, fair repair pricing, and honest recommendations.

All Seasons' Pool Service
Service area: Gilroy, Morgan Hill, and San Martin
Rating: 4.6 stars on Yelp
Services: Weekly service, one-time cleans, equipment repair, tile & plaster
ð Call (408) 710-6186 · ð Directions
All Seasons runs a smaller, tighter operation than the route-based pool companies in the corridor. They bring their own chemicals and equipment, service residential and commercial, and they're one of the few that'll do one-time cleans as well as weekly. Good option if you want a single point of contact instead of a rotating tech.
Why locals pick them: Personal service and fewer accounts per tech. Reviewers mention easy scheduling, transparent pricing, and no pressure to add services you don't need.

T & H Pools
Service area: Gilroy and surrounding communities
In business since: 1998
Type: Family-owned, locally operated
ð Call (408) 842-3253 · ð Directions
T & H is a family-run Gilroy operation with almost 30 years in the same market. They do weekly residential service, repairs, equipment swaps, and some new construction. If you live in Gilroy proper and want a company that's not going to ghost you for a bigger commercial contract, they're a safe local pick.
Why locals pick them: Consistency and Gilroy-specific familiarity. Reviewers mention the same tech for years running and prompt response when equipment fails.

How We Picked These
We pulled listings from Google Maps, Yelp, Angi, and Nextdoor, verified operating status, read recent reviews, and prioritized pool service companies based in Morgan Hill, Gilroy, or San Martin. Closed businesses, out-of-area chains with no local route presence, and companies with no verifiable phone contact were excluded.
Weekly Pool Service: What It Includes
A standard weekly service in the South Valley typically covers: skimming surface debris, brushing walls and steps, vacuuming, emptying skimmer and pump baskets, testing and balancing chemicals, and a quick equipment check. Expect $150â$225 per month for a standard residential pool, with chemicals sometimes billed separately. Larger pools, spas, or salt systems usually cost more.
DIY Pool Maintenance
You can absolutely maintain a pool yourself - many South Valley homeowners do. You'll need a test kit (Taylor K-2006 is the standard), chlorine, pH adjusters, and an hour or two a week in season. The reason people hire a service is usually equipment troubleshooting, not cleaning: catching a small issue before it becomes a $2,000 repair.
Equipment Repair and Replacement
Pool pumps typically last 8â12 years in the South Valley; heaters about 10â15; filters (cartridge or DE) 15+ with element swaps. Before you replace anything, get a diagnostic from a service company - and a second opinion if the quote feels off. A seized pump is sometimes just a bad capacitor.
Seasonal Notes for the South Valley
Summer heat drives chlorine demand up fast - expect to pay more for chemicals July through September. Fall leaf drop is the biggest single-cause of clogged filters and dead pumps in our area; a leaf net or cover pays for itself. Winter is a good time to get tile cleans, plaster inspections, and equipment upgrades done at slower-season rates.
How to Choose a Pool Service
Ask three questions: How many years on this route? Who specifically will service my pool? And what's your policy when a tech is out? A company that gives you the same tech week over week catches problems early. A company with a revolving cast of subs won't.
FAQ
How much does weekly pool service cost in Morgan Hill or Gilroy?
$150â$225/mo is typical for a standard residential pool, chemicals sometimes included. Salt systems, spas, or larger pools cost more. Get two quotes.
Do pool service techs need a license?
For routine cleaning and chemical service, no. For major equipment installs, replumbing, or electrical, yes - CSLB C-53 (Swimming Pool Contractor) is the relevant license. Always verify license status on the CSLB website before signing a repair contract over $500.
How often does a pool actually need service?
Weekly during swim season (AprilâOctober). Biweekly is fine for some pools OctoberâMarch, but chemicals still need attention at least weekly if the pool is uncovered.
