🛠️ How to Repair a Crack in Your Pool Skimmer
A cracked pool skimmer can lead to costly leaks, inefficient filtration, and even structural damage if left untreated. Fortunately, many minor skimmer cracks — especially in plastic skimmer bodies — can be successfully repaired without full replacement if caught early. Skimmer cracks are most often caused by poor installation by the pool builder, age or frost lensing/ground movement.
Here’s what you need to know to assess and fix a cracked pool skimmer safely and effectively.
🔍 Step 1: Identify the Crack
Carefully inspect the skimmer, both inside the basket area and along the outer body (especially near the throat and connection points). Look for:
-
Hairline or surface cracks
-
Deeper structural fractures
-
Water loss around the skimmer
-
Damp or eroded ground surrounding the skimmer
If your pool loses water and no leak is visible in the liner, a cracked skimmer body is a common culprit.
🧰 Step 2: Gather Tools & Materials
You'll need:
-
Pool-safe epoxy or marine-grade putty (e.g. Atlas, AquaMend, Leakmaster)
-
Sandpaper (medium to coarse grit)
-
Clean rag and acetone or rubbing alcohol
-
Small brush or putty knife
-
Gloves and protective eyewear
Optional: Skimmer plug (to block water while working)
🧼 Step 3: Clean and Prepare the Area
-
Drain the pool water below the skimmer or use a plug to keep water away from the repair area.
-
Dry the skimmer thoroughly.
-
Sand the area around the crack to roughen the surface and improve adhesion.
-
Clean the area using alcohol or acetone to remove oils and residue.
⚠️ Ensure the area is completely dry before applying any repair materials.
🧪 Step 4: Apply the Repair Material
-
Mix and apply the epoxy or putty according to manufacturer instructions.
-
Push the material firmly into the crack and spread slightly beyond the edges.
-
Smooth the surface with a putty knife or gloved finger.
-
Let it cure fully (typically 2–24 hours depending on product).
Some products can even cure underwater — but dry applications offer the strongest bond.
🧱 Step 5: Test the Repair
Once the epoxy is fully cured:
-
Remove any skimmer plugs
-
Refill the pool to skimmer level
-
Monitor for leaks over the next 24–48 hours
-
Check for water loss or dampness near the skimmer housing
🧠 When to Replace the Skimmer
Some cracks, especially those that are deep or extend into connection ports, may be too serious for patching. Consider replacement if:
-
Cracks reappear after repair
-
You notice significant structural instability
-
The skimmer body is brittle, warped, or splitting
Skimmer replacement usually involves cutting into the deck or pool wall and should be handled by a pool professional.

Additional helpful directions for fixing a pool skimmer:
If you discover a crack in your pool skimmer, timely repairs are essential to prevent further damage and maintain proper water circulation. Here’s a step-by-step guide to help you effectively fix the issue.
Step 1: Plug the Skimmer
Start by using a white square skimmer plug to seal the skimmer face. This will prevent water from flowing into the skimmer while you perform the repair.
Step 2: Close the Valve
After plugging the skimmer, immediately close the valve connected to that skimmer. This will help ensure that the skimmer remains dry while you work on the crack.
Step 3: Prepare the Area
Once the skimmer is dry, clean and dry the area around the crack thoroughly. Removing any debris or moisture will help the repair materials adhere better.
Step 4: Drill a Hole (Optional)
For additional durability, consider drilling a small hole at the end of the crack. This can help prevent the crack from spreading further down the skimmer wall. 
Step 5: Sand the Area
Use sandpaper to sand the area around the crack, creating a smooth surface. Aim for about 1-2 inches surrounding the crack to ensure proper adhesion of the repair material.
Step 6: Apply Pool Epoxy
Using a high-quality pool epoxy, fill in the crack and smooth it out, extending about 1/2 inch beyond the crack itself. Follow the manufacturer’s instructions for optimal results.
Final Steps
Allow the epoxy to cure completely according to the product guidelines before removing the skimmer plug and reopening the valve.
By following these steps, you can effectively repair a crack in your pool skimmer and keep your pool in top shape!
