I've had a lot of work done by Bruce Solomon over the years However ,this job called for repairing a broken sewer line under the concrete(6-7 inches) floor ,rebar and 4-5 ft of soil in my utility room .The effort to cut the damaged cast iron pipe and replace was extremely labor intensive and physically difficult .Danny did a $@!#% of a job under the circumstances.They left the work site clean.Very professional and good guys.
