    From their initial scope to the completion of the job, Drew and his team were communicative and consistent. The final invoice matched the initial quote without any added costs or surprises, and most impressively, they finished the complex task of excavating and repairing the sewer line to our century-old home in less than 8 hours - a full day ahead of schedule. The team here was professional and friendly - highly recommend!

I called Black Rock Underground, and for no charge at all, they performed a sewer scope and said that there was actually no problem! No charge, just good news and advice on how to keep the rats from going down by the water main! Thanks so much, Black Rock Underground! To be sure that if I do have an issue, I'll be reaching full review

Their expertise and knowledge was invaluable. They bored the almost 200 feet of pipe underground without need for a lengthy open trench and minimized impact to the stream and environmental corridor in which they were forced full review
