Hydro-Jetting & Drain Cleaning


Snaking a drain only punches a hole through the clog; it doesn't clean the pipe. We use hydro-jetting, which blasts high-pressure water into the line. This scours the pipe walls, removing grease, scale, and invasive tree roots. It is the most effective way to prevent recurring drain clogs.

Camera Inspection & Diagnosis


Before we dig or repair, we look. We feed a high-definition sewer camera into your cleanout to visually inspect the inside of the pipe. We look for root intrusion, bellies (sags), cracks, or offsets. This diagnostic step allows us to recommend the exact repair needed—whether it's a simple cleaning or a structural repair.

Trenchless Pipe Lining in Cornwall, PA


If your sewer line is failing due to roots or cracks, you don't always need to dig it up. We use Cured-In-Place Pipe (CIPP) lining. We pull a resin-coated liner into the damaged pipe and inflate it. Once it cures, it forms a rock-hard, jointless pipe-within-a-pipe that is guaranteed to last for decades. This "no-dig" solution is faster, cleaner, and often more cost-effective than excavation.





Frequently Asked Questions


  • How do I know if my sewer line is broken? Common signs include frequent backups, gurgling toilets, wet spots in the yard, or a sewage smell outside the house.
  • Will trenchless repair work for my home? In most cases, yes. However, if the pipe has completely collapsed or has a severe belly (dip), we may need to excavate that specific section to correct the grade.
  • How long does trenchless replacement take? Usually 1 to 2 days, compared to a week or more for traditional excavation. It gets your plumbing back online much faster.
  • Is hydro-jetting safe for old pipes?We always inspect the pipe with a camera first. If the pipe is structurally sound, jetting is safe. If it is crumbling, we will recommend replacement.
  • Do you offer a warranty on the liner?Yes. Our liners typically come with a 50-year manufacturer warranty. It is a permanent solution, not a patch.

Cornwall, PA Insights: Population,
Zip Codes, Influence, and Service Areas

Cornwall was initially settled by Peter Grubb in 1734. Peter was a Chester County stonemason who came to, what was then Lancaster County, in search of high quality stone for quarrying. First building his house and then a store, he discovered magnetite iron ore nearby and decided to test its quality, he found the ore to be exceedingly pure. Grubb wrote to Philadelphia and in 1734 was granted a warrant to purchase 300 acres (1.2 km2) of land. For three years Peter followed veins of ore until he found a large deposit that was easily accessible; however, this ore was not within the bounds of his property. So in 1737 he purchased an additional 142.5 acres (0.577 km2) of land. In 1742 Peter built a cold blast furnace and named it Cornwall, after his father's birthplace in England. The Cornwall Iron Mine was, at one time, the largest open-pit mining operation in the world. They were mined continuously until June 30, 1973, totaling 236 years of production.
