When a pipe bursts at midnight, a water heater quits before a houseful of guests arrives, or a sewer line backs up into the basement, the last thing you want to do is gamble on the first name in a search result. The Treasure Valley is growing fast, and so is the list of plumbing companies competing for your call. To help homeowners and business owners across Boise, Meridian, Nampa, Caldwell, Eagle, Garden City, Kuna, Star and Middleton, we put together this guide to the top 5 plumbers in Boise and the surrounding Treasure Valley.
Our picks weren’t pulled from a hat. We weighed verified customer reviews, transparency on pricing, range of services (everything from drain cleaning and water heater replacement to trenchless sewer repair and 24/7 emergency plumbing), local ownership, and how consistently each company shows up for its neighbors. The result is a mix of established names and smaller, community-rooted shops that punch well above their weight.
Five Star Service Pros Plumbing — Boise, ID
Taking the top spot is Five Star Service Pros Plumbing, a locally owned company headquartered in downtown Boise that has quietly become one of the most trusted plumbing teams in the entire Treasure Valley. The numbers tell the story: Five Star Service Pros holds a perfect 5.0-star rating from more than 340 Google reviews — a level of consistency that’s remarkably rare in the trades, where even great companies tend to collect the occasional one-star.
Founded in 2018 and led by an owner with nearly 40 years of hands-on plumbing experience, the company has built its reputation on honest, reasonable pricing and prompt, professional service. Customers repeatedly single out owner Ray and his crew for showing up on time, communicating clearly, and refusing to upsell work that isn’t needed.
Where Five Star really separates itself is the breadth of what it handles under one roof. Their services include:
- Residential plumbing and commercial plumbing
- Drain cleaning and hydro jetting
- Sewer repair, sewer camera inspections, and trenchless sewer repair & pipe lining (no digging up your yard)
- Water heater repair and replacement
- Toilet repair and replacement
- Flood repair and restoration
- 24-hour emergency plumbing, seven days a week
That trenchless capability is a genuine differentiator — most homeowners dread sewer line work because of the mess and the cost, and Five Star’s minimally invasive approach restores pipes without tearing up driveways, sidewalks, and landscaping. The team serves Boise, Meridian, Eagle, Kuna, Star, Nampa, Caldwell, Middleton and the entire Treasure Valley, and offers free estimates.
Best for: Just about anything — but especially sewer and water-line repair, trenchless work, and after-hours emergencies. Contact: (208) 279-6336 · fivestarservicepros.com

Ritchie Plumbing — Eagle & Boise, ID
With more than 35 years of experience, Ritchie Plumbing is a Treasure Valley mainstay that has earned a 5-star reputation across nearly 400 verified customer reviews. Based out of Eagle and serving Boise, Meridian, Nampa, Caldwell, Garden City, Kuna, Star, Middleton and Fruitland, Ritchie leans into the bigger projects: kitchen and bathroom remodels, radiant floor heating, water treatment and softener systems, gas piping, and water heater installation. If you’re renovating or building rather than just patching a leak, they’re a strong, experienced call.
Cleanline Plumbing Solutions — Nampa, ID
Over in Canyon County, Cleanline Plumbing Solutions has built an impressive following with a near-perfect 4.9-star rating across roughly 200 Google reviews. Serving Nampa since 2000, the team is known for two things customers love: 24/7 availability with no extra fees for nights or weekends, and straightforward, upfront pricing. They handle everything from drain and sewer work to water heaters and repipes across Nampa, Caldwell, Meridian, Boise, Eagle and Star. For west-valley homeowners who want a responsive local crew, Cleanline is hard to beat.
RSM Plumbing — Caldwell, ID
If you specifically want to support a small, independent, family-owned shop, RSM Plumbing in Caldwell is a standout. Led by Michael Papp — a career Caldwell firefighter — RSM is exactly what it sounds like: not a franchise, not a national chain, just a local family business that holds a flawless 5.0-star rating and an A+ rating with the Better Business Bureau. They’re also fully licensed for Idaho public works and handle sewer and water-line replacement in-house with their own excavation equipment. Serving Caldwell, Nampa, Boise and the surrounding communities, RSM brings a personal, community-first approach where you deal directly with the owner.
Prime Plumbing — Nampa, ID
Rounding out the list is Prime Plumbing, a reliable, locally owned company based in Nampa with 9+ years serving the Treasure Valley. Prime earns consistently strong reviews for punctuality, fair pricing, and quality workmanship on bread-and-butter jobs like toilet replacement, water softener installation, and general repairs. It’s the kind of dependable neighborhood plumber that’s perfect for everyday fixes and quick, no-drama service in Nampa, Caldwell and Meridian.
How to Choose the Right Plumber in the Treasure Valley
No matter which company you call, a few quick checks will save you headaches: confirm they’re licensed and insured in Idaho, ask whether estimates are free and pricing is flat-rate or hourly, read recent reviews (not just the star average), and make sure they actually service your city — coverage varies between Boise, Meridian, Nampa, Caldwell, Eagle and the outlying towns. For emergencies, verify that “24/7” really means 24/7 and ask whether after-hours calls carry an extra fee.
