Frequently Asked Questions
Lancaster sits on expansive clay soil that swells when wet and shrinks when dry. This constant movement can crack pipes under foundations (slab leaks), stress connections throughout the home, and even affect gas lines. We’re experienced in identifying foundation-related plumbing problems and recommending solutions that account for continued soil movement.
Lancaster’s hard water causes significant mineral buildup that reduces water heater efficiency and lifespan. We recommend flushing tank water heaters every 6 months (manufacturers recommend this frequency for hard water areas) and considering tankless systems that handle hard water better when replacing older units.
Unexplained water bill increases often indicate hidden leaks, frequently slab leaks under the foundation or toilet flapper leaks that waste hundreds of gallons daily. Our leak detection equipment can locate problems non-invasively, often saving significant water damage and expense.
We prioritize same-day service for Lancaster customers whenever possible. For genuine emergencies (gas leaks, major water events, complete system failures), we maintain 24/7 availability and typically respond within 60 minutes.
Absolutely. Much of our Lancaster work involves older homes with unique challenges like galvanized pipes, aging HVAC systems, and plumbing affected by foundation movement. We’re experienced with these properties and honest about repair-versus-replace decisions.
