A dry trap, a cracked drain fitting, a failed wax ring or a blocked vent can all let sewer gas into a room. We locate the source with a smoke test or visual inspection and seal it.
We work with all common types of drain pipe found in Colorado homes, including PVC, ABS, cast iron and copper. Our technicians are experienced in repairing and replacing sections of various pipe materials for compatibility and longevity with your existing plumbing system.
Harsh chemical cleaners can soften older ABS glue joints and corrode metal drain parts with repeated use. They also rarely clear grease or scale fully. A mechanical auger or hydro-jet is safer and more effective.
Tightening a loose slip nut or replacing a plastic trap is a reasonable DIY job. If the leak is from a cracked tailpiece, a corroded metal drain or inside a wall, a plumber can make a lasting repair and check for hidden damage.
Hydro-jetting is a powerful drain cleaning method that uses high-pressure water to scour the inside of pipes, effectively removing stubborn clogs, grease buildup and even tree roots. It's usually used when traditional snaking isn't enough, or for preventive maintenance on main sewer lines, especially in older homes with buildup issues.
