A well-maintained pool is a beautiful and relaxing centerpiece to any backyard. But when a pool starts to fall into disrepair, it can quickly become a source of stress, unexpected expenses, and even safety hazards. Whether you’re a new pool owner or a seasoned swimmer, understanding the key signs that your pool needs maintenance or repair is essential for extending its lifespan, maintaining property value, and ensuring a safe and enjoyable swimming environment.
Below, we explore the most important indicators that your pool may be crying out for help, from minor cosmetic issues to serious structural or mechanical problems. This way you will know when to have proper swimming pool maintenance done or if the issues are simple enough to tackle yourself.
Cracks in the Pool Structure
One of the most noticeable red flags that will indicate that you are in need of pool maintenance services is the appearance of cracks along the pool walls, floor, or surrounding deck. While small surface cracks in concrete or plaster can be normal due to weather changes and settling, larger or spreading cracks are not. These can lead to water leakage, structural instability, and even damage to surrounding landscaping or the foundation of nearby structures. Any crack that grows, feels deep to the touch, or causes visible water loss should be addressed by a professional pool technician as soon as possible.
Water Loss or Reduced Water Levels
All pools lose some water due to evaporation, splashing, or backwashing, but if you’re refilling your pool more than once a week, there’s likely a bigger issue. Consistent water loss could indicate a leak in the plumbing, the liner, or the pool structure itself. Leaks can be particularly insidious, as they may be hidden underground or within your filtration system. Ignoring the problem can result in inflated water bills, erosion, and long-term damage to both the pool and the property.
Cloudy or Discolored Water
Pool water should be crystal clear. If it turns cloudy, green, or discolored, it’s a clear sign that something is off with your water chemistry or filtration system.
Algae growth, bacteria, or chemical imbalances (such as high levels of phosphates or low sanitizer levels) can all lead to murky water. Cloudy water isn’t just unattractive, it can be unsafe to swim in, as harmful microorganisms might be present. Regular testing and treatment of your water is necessary, and if problems persist, your pool may need a full chemical treatment or a deep clean.
Faulty Pool Equipment
Your pool’s pump, filter, heater, and chlorinator are the backbone of its functionality. If you notice your pump is making loud noises, struggling to circulate water, or turning on and off erratically, it may be due for maintenance or replacement. Similarly, if your filter isn’t clearing out debris effectively or the heater isn’t raising the water temperature as expected, it’s time to get them inspected.
Even subtle changes, like reduced water flow through jets or air bubbles in the return lines, can point to more serious underlying issues like clogged impellers, leaks in suction lines, or failing O-rings.
Stains on the Pool Surface
Staining can occur on concrete, tile, or vinyl pool surfaces for a variety of reasons. Organic stains come from leaves, algae, or debris and are often green or brown. Metal stains—typically blue, green, or reddish-brown—may be caused by iron, copper, or manganese in the water supply or plumbing.
While some stains can be treated with brushing and specific chemical treatments, others may require resurfacing, acid washing, or targeted repairs. Persistent or worsening stains should never be ignored.
Damaged or Worn-Out Pool Liner
For vinyl-lined pools, the liner is critical to maintaining the pool’s structure and preventing leaks. Over time, liners can fade, wrinkle, pull away from the edges, or tear, especially in harsh sun, cold temperatures, or due to poor chemical maintenance.
If your liner shows signs of bubbling, stretching, or cracking, it could be allowing water to seep behind it, leading to mold, algae, or even structural damage. Most vinyl liners need to be replaced every 8 to 12 years depending on care and climate.
Inefficient or No Circulation
A pool’s circulation system is what keeps the water clean, safe, and swimmable. If you’re noticing “dead spots” in the water where debris accumulates, or if the pool water feels warmer in certain areas and cold in others, the circulation may be compromised. This can stem from clogged filters, a failing pump, air leaks in the plumbing, or broken return jets. Poor circulation not only reduces the effectiveness of your chemicals, but it can also lead to bacteria and algae blooms.
Peeling or Flaking Plaster
In concrete or gunite pools, the interior surface is often finished with plaster. Over time, this plaster can degrade, especially if the water chemistry isn’t well maintained. Flaking, chipping, or rough patches on the pool surface can not only be uncomfortable for swimmers but may expose the underlying structure to wear. If the surface feels abrasive to the touch or you notice white or grayish spots appearing, it may be time for a professional resurfacing job.
Foul Odors or Strong Chlorine Smell
A properly balanced pool should not emit any strong odor. If you detect a potent chlorine smell, it’s often a sign of chloramine buildup, a byproduct of chlorine reacting with contaminants like sweat and urine. Ironically, it means the pool is under-chlorinated and needs to be “shocked” with a higher dose of sanitizer. Musty, sour, or sewage-like odors could point to bacteria, algae, or even water stagnation. Persistent odors are a clear signal that your pool needs maintenance before health risks increase.
Visible Algae or Slippery Surfaces
Algae can quickly take over a neglected pool. If you see green, yellow, or black patches on the walls, floor, or steps, or if the surfaces feel slimy or slippery, algae are likely present. Green algae is most common and easiest to treat, while yellow (mustard) and black algae are more resistant and often require professional intervention.
Algae not only makes your pool look uninviting but can also be hazardous by making surfaces dangerously slick.
Inconsistent Chemical Readings
Regularly testing your water for pH, chlorine, alkalinity, and other chemical levels is vital to pool health. If you’re constantly adjusting chemicals and can’t seem to keep them balanced, it may indicate a larger issue such as biofilm buildup, ineffective circulation, or even a failing chlorinator. Wild swings in water chemistry can also accelerate the wear and tear of equipment, stain surfaces, and irritate skin and eyes.
Lights Not Working or Flickering
If your pool lights flicker, don’t turn on, or seem dimmer than usual, you should not ignore the issue. Pool lighting involves underwater electrical systems, and any malfunction can pose a serious safety hazard. Sometimes it’s a simple bulb replacement, but other times, the problem lies in faulty wiring, moisture infiltration, or degraded seals. Always consult a licensed pool electrician to address lighting issues safely.
Surrounding Deck or Tile Damage
The health of your pool isn’t just confined to the water itself. Cracked or lifting deck materials, loose tiles, or deteriorating caulking around the pool’s edge can indicate shifting ground, water leaks beneath the surface, or age-related deterioration. These issues not only affect aesthetics but can create tripping hazards or even structural damage if left unaddressed.
Unusual Increase in Utility Bills
A sudden spike in your water or electricity bill could be due to your pool. Leaks, faulty pumps, inefficient heaters, or malfunctioning automation systems can all consume more resources than necessary. If you’re seeing higher-than-normal utility charges, and you suspect your pool, it’s time for a professional evaluation of all systems.
