The Complete Guide to Fixing Pool Skimmer Leaks in Victorville, CA

A cracked skimmer is one of the most common causes of pool leaks, leading to water loss, higher bills, and potential pool damage. If you’re a pool owner in Victorville, CA, understanding skimmer crack repair is essential for maintaining your swimming pool’s health and efficiency. This article, brought to you by GFC Pool Cleaning & Repair-your local experts in pool cleaning, leak detection, and repair-will walk you through everything you need to know about identifying, repairing, and preventing skimmer cracks. We use Leaktronics’ industry-leading leak detection equipment to ensure your pool stays leak-free and crystal clear.

What Is a Pool Skimmer and Why Does It Crack?

A pool skimmer is a crucial component of your swimming pool’s filtration system. It sits at the waterline and draws in surface water, capturing debris before it sinks. Over time, the skimmer, especially in concrete and plaster pools, can develop cracks due to shifting soil, freeze/thaw cycles, or improper installation. These cracks often form where the plastic skimmer meets the concrete pool wall, a vulnerable area known as the “cold joint”.


Cracks in the skimmer body, skimmer throat, or around the skimmer area can compromise the pool’s structure and lead to significant water loss. Regular pool maintenance and inspection are key to catching these issues early.

How Do Skimmer Cracks Lead to Pool Leaks?

When a crack forms in the skimmer body or where the skimmer meets the pool wall, water can escape through these openings. Even small cracks can result in a significant leak over time, causing the water level to drop and increasing your water bills. Leaks around the skimmer also reduce the efficiency of your pool’s filtration system, leading to cloudy water and higher maintenance costs.


In some cases, cracks where the skimmer meets the pool wall can allow water to seep into the surrounding soil, potentially undermining the pool deck or causing further structural issues.

What Are the Signs of a Skimmer Leak?

Look for these common signs of a skimmer leak:


  • Noticeable drop in pool water level, especially after refilling the pool
  • Wet spots or standing water around the pool deck or skimmer area
  • Unbalanced pool water chemistry or increased chemical usage
  • Visible cracks in the skimmer body or throat
  • Air bubbles returning to the pool via the jets


If you notice any of these symptoms, it’s time to investigate further.

How Can You Detect a Skimmer Crack or Leak?

Detecting a skimmer crack starts with a careful visual inspection. Remove the skimmer lid and basket, then check the skimmer body, throat, and the area where the skimmer meets the pool wall for visible cracks or gaps. Use a flashlight to spot smaller cracks, and feel around the skimmer area for irregularities.


A simple dye test can help confirm if a crack is leaking. Add a small amount of pool dye near the suspected crack; if the dye is drawn into the crack, you have a leak.


For more complex cases, professional leak detection is recommended. At GFC Pool Cleaning & Repair, we use Leaktronics’ advanced leak detection equipment, including hydrophones and amplifiers, to pinpoint leaks quickly and accurately-even those hidden under concrete or pool decks.

Why Is Professional Leak Detection Important?

Professional leak detection goes beyond what the naked eye can see. Using Leaktronics’ industry-leading technology, our technicians can:


  • Identify leaks inside the pool shell, skimmer, plumbing, and underground pipes
  • Pinpoint the exact location of the leak, reducing unnecessary digging or repairs
  • Detect even the smallest leaks that cause significant water loss over time


This precision means faster repairs, less disruption, and long-term peace of mind for pool owners in Victorville, CA.

What Materials Are Used for Skimmer Crack Repair?

The most effective repair materials for skimmer cracks include:


  • Epoxy putty: A two-part, hand-moldable compound that cures underwater and creates a durable seal.
  • Epoxy resin: Used for larger cracks, this material can be injected to fill and seal gaps in the skimmer body or throat.
  • Silicone sealant: Ideal for sealing small cracks or adding an extra layer of protection after using epoxy.
  • Urethane foam: Sometimes injected around the skimmer body to fill voids and stabilize the area.


These materials are chosen for their ability to bond to wet environments and withstand pool chemicals.

How Do You Fix a Crack in a Pool Skimmer?

Here’s a step-by-step overview of the skimmer crack repair process:


  • Lower the water level below the skimmer to expose the crack and ensure a dry surface for repair materials to adhere properly.
  • Clean the area thoroughly, removing debris and old sealant from the crack.
  • Prepare the epoxy putty or resin according to the manufacturer’s instructions. For small cracks, roll the putty into a rope and press it firmly into the crack, smoothing the edges for a watertight seal.
  • For larger cracks, inject epoxy resin using a static mixer or applicator to fill the void completely.
  • Allow the repair to cure fully before refilling the pool and restarting the filtration system.


For added protection, apply a layer of silicone sealant over the cured epoxy to further seal the crack and prevent future leaks.

Is Epoxy the Best Solution for Skimmer Repair?

Epoxy is widely regarded as one of the best solutions for skimmer crack repair because it:


  • Bonds strongly to both plastic and concrete surfaces
  • Cures underwater, so draining the entire pool isn’t necessary
  • Remains flexible enough to handle minor pool movement
  • Resists pool chemicals and UV exposure


Products like Epoxybond Pool Putty and AquaGuard 5000 Super Epoxy are popular choices for both DIY and professional repairs.

Can You Repair a Skimmer Crack Yourself, or Should You Call a Pro?

Small cracks in the skimmer body or throat can sometimes be repaired by handy pool owners using epoxy putty or sealant. However, for larger cracks, leaks around the skimmer, or recurring problems, it’s best to call a professional.


At GFC Pool Cleaning & Repair, we offer expert skimmer repair and leak detection using Leaktronics equipment, ensuring the job is done right the first time. Professional repairs are more durable and can prevent costly damage to your pool structure.

How Can You Prevent Future Skimmer Leaks?

Prevention is key for long-lasting pool health:


  • Schedule regular pool maintenance and inspections
  • Address minor cracks or leaks promptly before they worsen
  • Avoid heavy impacts or pressure on the pool deck near the skimmer
  • Use only recommended repair materials like epoxy and silicone for any fixes
  • Ensure proper installation if replacing a skimmer


Routine care from a trusted local pool service like GFC Pool Cleaning & Repair can help you avoid major repairs down the line.
