Replacing an Existing Pool

Replacing an Existing Pool in Illinois Many older pools across Illinois especially in established suburbs and neighborhoods from Chicago to Springfield and beyond were originally built using concrete or gunite. Over time, these materials can become rough, chalky, and prone to cracking due to the state’s freeze-thaw cycles and seasonal extremes. Because gunite is porous, it’s also more vulnerable to algae growth, leading to stubborn stains and making pool chemistry harder to balance. Fiberglass pools offer a better long-term solution. With their smooth, non-porous surface, they resist algae buildup and are far easier to maintain. When properly cared for, a fiberglass pool can remain crystal clear and beautiful for decades with significantly less maintenance and chemical usage than a concrete pool. That means more time relaxing and less time scrubbing no matter what part of Illinois you call home.
