Older homes in Watertown often have smaller diameter pipes and aging drain lines that are more prone to clogs. Over decades, soap scum, hair, grease, and mineral deposits build up on pipe walls, reducing flow capacity. Cast iron and galvanized pipes common in pre-1970s homes are especially susceptible to this buildup.Tree roots are another major culprit in established neighborhoods. Mature trees send roots toward sewer lines seeking water, and they can infiltrate joints and cracks in older pipes. Ground settling over time can also create low spots where debris accumulates, leading to recurring blockages.Regular professional drain cleaning using hydro jetting can remove these accumulated deposits and restore proper flow. We use high-pressure water to scour pipe walls clean without damaging the pipes themselves. For homes with recurring issues, we can perform camera inspections to identify root intrusion, pipe damage, or other structural problems that need addressing. Preventive maintenance every year or two keeps drains flowing freely and prevents emergency backups.
