Kitchen and Bathroom Drain Cleaning
Slow drains and bad odors usually mean buildup in the pipe. We clear it without damaging your plumbing, and we look for what caused it so it doesn't come right back.
Leak Detection and Pipe Repair
Hidden leaks quietly rot cabinets, subfloors, and framing. We use proven detection methods to find leaks in supply lines and drain pipes, then repair or replace the affected sections. We also swap out worn shut-off valves and aging supply lines before they fail.

Preventative Plumbing Maintenance

- Routine plumbing inspections, especially in older homes
- Simple garbage disposal maintenance
- Checking supply lines and replacing aging shut-off valves
- Faucet and fixture checks for early leaks
- Regular drain cleaning to prevent clogs
Prepping your plumbing before a remodel also prevents surprises once walls are open.

Why Choose EP Plumbing, Heating & Air for Bathroom and Kitchen Plumbing in Longmont?
- We know Longmont homes. Older houses near Downtown Longmont often have dated supply lines and shut-off valves that need updating. Newer builds toward Union Reservoir have their own quirks. We've worked on both, so we're not guessing.
- We're licensed and insured in Colorado. Our plumbers are trained, background-checked, and up to date on plumbing codes and permitting requirements. That protects your home and your investment.
- We're honest about repair versus replacement. If a $40 cartridge fixes your faucet, we won't push a new one. If your disposal is on its last legs, we'll tell you straight so you don't pay twice.
- We respect your home. We show up on time, keep the work area clean, and leave every job site the way we found it, minus the problem.
- We're a local, family-owned team. That means faster scheduling, responsive service, and personalized care for homeowners, remodelers, and property managers across Longmont and Boulder County.
