"They truly live by the code of "you get what you paid for". The price was cheaper than expected (and they included a free estimate too). So ultimately, our slow bathtub drain was cleared. However, the technician had terrible housekeeping. After stripping the caulking around the overflow valve, they left the caulking pieces in the bathtub and told us to flush them down the drain (?!). They said the provided bio solution would clear the pieces just fine...but why do that when a trash can is less than a foot away?? Then, they did not offer to reseal the valve they just opened...just left a mess for us to pick up. As such, we will not be using them again next time...free estimate or not. If we wanted the bare minimum, we would have done it ourselves."

FAQs for sewer main install, replace or repair projects in Downingtown, PA

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
