Sewer Line and Drain Camera Inspection in Hockessin, DE
A camera inspection shows the condition of your sewer line and main drains. We look for roots, bellies, cracks and buildup before they cause a backup. Older homes with clay or cast iron lines benefit most from regular checks. We record the inspection and give you a copy. If cleaning or repair is needed, we explain your options.

Backflow Preventer Testing in Hockessin
Backflow preventers protect the drinking water supply from contamination, and many water providers require annual testing for irrigation and commercial devices. Our certified testers check each valve and file results with your water utility as required. If a device fails, we repair or replace the internal parts. We also check that devices are protected from heat and freezing where needed. Keeping up with testing avoids fines and water shutoffs.
Drain Line Inspections for Maintenance in Hockessin
As part of complete plumbing maintenance, we offer drain line camera inspections. This lets us see the condition of your main sewer lines, spotting potential blockages from roots or grease buildup, or structural issues like cracks and offsets made worse by shifting soil. Older homes in the north often have basements, while many newer and coastal homes sit on slabs or elevated foundations. Early detection through inspection can prevent severe backups and costly emergency repairs.
Gas Line and Repipe Inspections in Hockessin, DE
Safety comes first with gas lines, and our maintenance includes thorough inspections for leaks, corrosion, and proper valve operation. For older homes in Hockessin with polybutylene or aging galvanized pipes, our repipe specialists can assess the need for replacement. Regular checks help spot potential hazards or signs of coming pipe failure, preventing dangerous situations and significant property damage.
Leak Detection and Slab Leak Checks in Hockessin
Older homes in Delaware may still have galvanized supply lines and cast iron drains, both of which deteriorate with age. Soil movement and hard water can wear buried or under-slab water lines until they leak. We check your water meter for hidden flow, test fixture valves and use acoustic and thermal tools to find leaks. Warm spots on floors, a running meter and unexplained high water bills are common signs. Finding a leak early prevents slab damage and mold.
Water Softener Maintenance in Hockessin
Water softeners fight hard water, protecting your pipes and appliances from mineral scale. Our maintenance service includes checking salt levels, cleaning the brine tank, confirming the regeneration cycle works correctly, and inspecting valves and resin beds. Proper softener maintenance extends its life and keeps soft water flowing to your home, preventing expensive scale damage.
Water Heater Maintenance in Hockessin
Regular water heater maintenance is key to preventing sediment buildup. Water in Delaware ranges from moderately soft to hard depending on the source, and groundwater areas often see more mineral buildup on fixtures. Our service includes flushing the tank, inspecting the anode rod for corrosion, checking the temperature and pressure relief valve, and examining all connections and heating elements. This extends the life of your unit, boosts efficiency, and helps avoid sudden cold showers or leaks.

Preventative Leak Detection in Hockessin, DE
Proactive leak detection is a key part of our plumbing maintenance. We use advanced tools to find hidden leaks in pipes, especially those under slabs or behind walls, which are common in older homes. Older homes in Delaware may still have galvanized supply lines and cast iron drains, both of which deteriorate with age. Catching these leaks early prevents serious water damage, mold growth, and wasted water, saving homeowners in Hockessin from extensive repairs down the line.
