What actually shortens joint life in Moreno Valley.
Heat is the headline and the daily swing is the real story. Summer afternoons well into the hundreds expand a concrete deck substantially, then the night drops far enough to pull it back. That full cycle happens every day for months, and every cycle asks the bead to stretch and recover. A sealant with flexibility left in it does that indefinitely. One that has hardened tears, usually straight down the middle. We see it across Moreno Valley in the same order every time. The bead loses its give first, then it splits, then it lets go of one wall. Around Moreno Valley Ranch, Rancho Belago and Sunnymead Ranch the pools are close enough in age that a whole street tends to reach that point within a season or two of each other.
