Pool Caulk Damage—Replace or Repair?

Posted by Greg on 5/26/16 9:56 AM

If you have a pool, then you may be due for replacing (or simply repairing) your pool caulk. Pool caulking, which is the slab of concrete that rests in between your pool and your deck, is essential. If you live in an area of the country that reaches freezing temperatures, pool caulking can help prevent freezing water cycles (or extreme heat) that can damage the foundation of your pool. But when and why should you replace it, and how often do you need to repair it? This article answers your most pressing questions.

Why and When Pool Caulking Needs Your Attention 

As a rule of thumb, you should plan on repairing your pool caulk about every five years. Some areas of your pool caulk can wait until about ten years, but you want to keep an eye on it—neglecting fractured pool calking can cause pulling away and cracking that can become very expensive to fix. If only a small part or section of the pool calking needs to be fixed, it’s not difficult to do by yourself. Use a sharp razor knife, and cut out the section that needs to be replaced, and fill it with new caulk. Just keep in mind that the new caulk will have a brighter color than the old, original caulk (which will appear duller in appearance.)

Is It Necessary to Hire a Professional If I’ve Never Done This Before?

If you’ve ever caulked something in your home (say, your shower or bathtub), you might want to hold off feeling like an expert just yet. Caulking your pool is a different (and much larger) kind of bathtub! If you’re repairing pool caulk for the first time, stick to a self-leveling pool caulk. This is much easier for amateur do-it-yourselfers than caulk such as gun grade caulking (which is what the professionals use, and must be mixed on site.) On average, expect to pay between $4-6 per linear foot. When repairing or replacing pool caulk, follow these guidelines so it’s as smooth of a process as possible:

  • Measure how much caulk you will actually need, and then purchase extra.
  • Invest in a high quality razor knife. Carefully cut out the section that you want to replace.
  • Make sure that the joint and deck are clean. Before adding new caulk, remove any dirt or debris from the area.
  • Keep your children and pets away from the pool. Many amateur DIY’s find that the process is going well, only to find little paw prints in their newly applied wet caulking!

Replacing or repairing pool caulk doesn’t have to be a different process, even if you’re doing it yourself. It does require the right equipment and material, and a smooth hand when replacing the new caulk. Whether you want to replace the pool caulking yourself, or you are interesting in hiring a processional, the experienced staff at Royal Swimming Pools can answer all of your questions—and direct you towards the answers.
