Hidden leaks cause some of the most expensive damage a home can face. Dave finds the source fast and fixes it right — before it turns into a much bigger problem.
A hidden leak rarely announces itself until the damage is already done — a water-stained ceiling, warped flooring, a musty smell, or a water bill that suddenly jumps for no reason. By then a small problem has often become an expensive one. David Johnson Plumbing locates the true source of the leak quickly and repairs it the right way, so you're not left guessing or paying to chase the same problem twice.
From pinhole leaks in supply lines to leaks hidden behind walls or beneath a slab, Dave brings decades of hands-on experience to every diagnosis. As a licensed Texas plumber, he explains exactly what he finds in plain language, gives you honest options, and fixes it cleanly — protecting your home, your plumbing, and your peace of mind.
