What You're Actually Paying For
A green pool cleanup is labor and chemicals, mostly labor. The tech has to shock the pool hard, brush every surface, run the filter around the clock, clean that filter repeatedly as it clogs with dead algae, vacuum the debris, and come back two or three times until the water clears. A light green pool is a two-visit job. A black pool that's been sitting since last fall can take a week of visits.
That's why the price range is so wide. Here's how companies price it in 2026, and how to tell which bucket your pool falls into.
Green Pool Cleanup Cost by Severity
| Condition | What It Looks Like | Typical Cost (2026) |
|---|---|---|
| Light green, hazy | You can see the bottom, water is tinted | $150–$350 |
| Medium green | Floor is visible but blurry, walls are slimy | $300–$600 |
| Dark green, opaque | Can't see the first step | $500–$900 |
| Black or swamp | Leaves, mosquito larvae, no visibility at all | $800–$1,500+ |
| Drain, acid wash, and refill | Pool is beyond chemical recovery | $800–$2,000 plus water cost |
Prices run higher for large pools, pools with attached spas, and pools with cartridge filters that need replacing partway through. Most companies quote after seeing the pool, not over the phone.
What's Usually Included
A standard green pool cleanup covers:
- Initial water test and a written plan
- Shock treatment, often two or three rounds
- Algaecide and a clarifier or flocculant
- Brushing walls, floor, and steps on every visit
- Multiple filter cleans or backwashes as the algae dies
- Vacuuming the settled debris, usually to waste
- Final balancing once the water is clear
When Draining Makes More Sense
Chemicals can recover almost any green pool, but at some point the chemical route costs more than starting over. Companies generally recommend a drain-and-clean when:
- The water is black and full of debris
- Cyanuric acid is so high that chlorine no longer works
- There's heavy staining that will need an acid wash anyway
- It's a vinyl or fiberglass pool with a surface that can't take repeated heavy shocking
Draining has its own risks. An in-ground pool drained at the wrong time with a high water table can lift out of the ground. That's why this is a pro job, and why reputable companies check the groundwater situation before they pull the plug.
How to Avoid Paying for It Twice
Most green pools come back green within a month if the cause isn't fixed. Before you pay for a cleanup, make sure the company answers these:
- 1Why did it turn green? Dead pump, clogged filter, empty chlorinator, high stabilizer, or just neglect. Each has a different fix.
- 2Is the equipment running right now? If the pump isn't circulating, no amount of shock will hold.
- 3What's the stabilizer (CYA) level? If it's very high, the cleanup needs to include a partial drain or the chlorine won't stick.
- 4What happens after it clears? Ask for a quote on weekly service at the same time. Many companies discount the cleanup if you sign up for a plan.
- 5Is there a guarantee? Some companies will come back free if the pool turns within a set number of days.
A good cleanup quote comes with a diagnosis. If the company just says "shock and brush, $400," you're buying a temporary fix. How to choose a pool service company covers the rest of the vetting process.
DIY or Hire It?
You can clear a light or medium green pool yourself for $50–$150 in chemicals and about a week of daily attention. The math changes when the pool is dark, when you don't have time to brush and clean the filter every day, or when you don't know why it went green. A failed DIY attempt usually costs more in chemicals than the pro would have charged, and the pool is still green.
