Frequently we repair broken drain lines. Some are above ground, others below the concrete slab or even outside. Each situation is unique. Often the old cast iron or steel drains rot and must be cut out, and then we tie in where the pipe is in good shape. We can install various sizes of PVC pipe in all types of locations.
The sign of a good plumber is how they install drain lines in a new or remodel situation.
Cardom Plumbing and Heating does not repair drywall or paint.
