Preventative Drain Maintenance and Unblocking in Denver, CO
Beyond emergency unblocking, GFR Plumbing offers preventative drain maintenance programs to keep your pipes clear and prevent future clogs. Regular inspections and scheduled drain cleaning can save you from costly repairs down the line. Higher elevations lower the boiling point of water, which affects water heater settings and relief valve performance in mountain homes. We can share best practices and schedule routine service for your Denver, CO property.

Main Line Blockage Unblocking in Denver
If multiple drains are blocked or water comes up in the tub when you flush, the blockage is likely in the main line. We find the cleanout and run a heavy cable with a cutting head toward the street. Roots, wipes and grease are the usual causes. Once flow is restored, a camera inspection can show what is going on in the pipe. We recommend next steps based on what we see.
Hydro Jetting for Stubborn Clogs in Denver
For the toughest drain blockages, including grease buildup, mineral deposits from hard water, or heavy sludge, hydro jetting is the most effective solution. This method uses high-pressure water streams to scour the inside of your pipes, clearing obstructions and leaving your drains very clean. It's an excellent preventative step for older homes in Denver.
Blocked Kitchen Sink Unblocking in Denver, CO
A kitchen sink full of standing water usually means grease and food have sealed the line. If a disposal is involved, we check that it is not jammed and that the outlet is clear. We remove the trap and run a drum machine into the wall line. Once the blockage is out, we flush with hot water. We also share simple tips to keep grease out of the line.
Main Sewer Line Unblocking in Denver, CO
Blockages in your main sewer line can affect all the drains in your home and often indicate a more serious problem, such as tree root intrusion or pipe collapse. GFR Plumbing uses video camera inspection to accurately locate and diagnose these issues. We follow up with hydro jetting or trenchless repair methods to restore full flow and prevent future backups. Expansive clay soils are a well-known problem in parts of Colorado, swelling with moisture and heaving slabs, basement floors, and buried pipes.

Hair, soap residue, and toothpaste are common culprits for clogs in bathroom sinks and tubs. Our plumbers are equipped to remove these stubborn blockages using snaking tools and eco-friendly drain solutions.
