They were amazing - so professional and incredibly fast - 48 hours from our initial conversation to completion! The photos include the broken sewer pipe that they replaced and the new one, as well as the pavers they removed and replaced - all in less than a day. I live in CO and my mom (whose house had the damaged sewer pipe) is in WA. I was helping her from across the country and truly relying on the expertise of UUE to take care of everything. Dziyana is a wizard! She made things happen I didn’t even know were feasible, took my call while at home, and did everything and more to make sure the project ran smoothly, all of my and my mom’s questions were answered, and the work was completed beautifully. She went far above and beyond! The whole team made a project that felt very daunting, instead, very easy - and were able to do it in a way that made everyone involved feel calm and confident. I give UUE my strongest recommendation!!

Expert Underground Utility Line Installation in Seattle, WA
Underground UE provides underground utility line installation for properties throughout Seattle. Our work covers water, sewer, electrical, gas, and telecom lines buried to meet City of Seattle depth and separation standards. Seattle properties present real site challenges. Many lots sit on dense clay soils that hold moisture and shift under load. Steep grades, high groundwater in low-lying areas, and tightly packed existing infrastructure in older neighborhoods all affect how a line gets placed. We assess each site before any excavation starts. We locate existing lines, evaluate soil conditions, and plan trench depth and backfill to match what the ground requires. Every installation is compacted in layers to prevent settling that could shift or damage new lines. Whether you are connecting a new build, replacing a failed line, or adding service to an existing structure, our crew handles the ground work from first cut to final grade. Call Underground UE to schedule a site assessment in Seattle.
