Phenomenal crew! Great communication keeping you informed on when they will be there. After the demo and installation on our job, they cleaned up very well and took everything away. Thank you Evergreen plumbing for doing the work and making our lives better. Would definitely use them again in future projects

Gwendolyn G.
Team showed up right on time, were very polite and thoughtful in that they immediately put on shoe covers, a lovely thought, but not needed. They diagnosed and fixed the issue in less than 3 hours. Cleaned and accepted payment. Even spent time playing with my dogs. Two enthusiastic thumbs up. Would absolutely recommend Andy and his team.
Reece H.
These guys are amazing! Exceptional service and were able to promptly diagnose leaking lawn issue. We had a big plumbing contractor come and estimated fix at around $3k. Andy and his team did it for a small fraction and in less time! Returning customers for sure! Thank you Evergreen Plumbing Authority!

we’re here to Answer all your questions
Can you repair my existing tankless water heater?
Yes — we fix ignition problems, error codes, temperature issues, scale buildup, and other failures.
Do tankless systems really save energy?
Yes. Tankless heaters only heat water when needed, lowering energy costs significantly.
When should I replace my tankless system?
If repairs become frequent, efficiency drops, or the unit is older than 12–15 years, replacement is often more cost-effective.
What Areas Do You Service?
We proudly serve Pierce County, Tacoma, Puyallup, and surrounding cities.
Do you handle venting and gas sizing for new installations?
Absolutely — tankless installs must be sized correctly for gas supply and venting. We handle the full install from start to finish.
Can I switch from a tank to a tankless system?
Yes — we’ll size the correct model for your home and handle all plumbing, gas, and vent modifications.
