"I?m incredibly disappointed with the work that was done at my property. Mine was a clear case of underbidding and miscommunications. The good: nice people and they did do a lot of work. Just not everything they bid on. Bad: the front yard of my house looks worse. We knew we were being fit in but they seemed to be in a hurry. They focused on one aspect. Overcharged a known addition to compensate for under bidding and still didn?t do the clear away that they were supposed to do. If his tractor couldn?t do the work he just didn?t do it. They were supposed to clear back an entire field and he stopped half way and said he was done and then he left the downed brush despite an email I had stating they would remove or burn the brush as their costs. When we pointed out the miscommunication it ?was what it was?. We spoke many times about what we wanted done - it shouldn?t have been a suprise. Again they did a lot of work but I?m upset they didn?t fulfill the terms. Would not recommend. "

FAQs for sewer main install, replace or repair projects in Lake Oswego, OR

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.
