Who We Are

A Portsmouth Plumbing Crew Built on Accountability

Behind Street Wise - Plumbing is a crew of journeyman and master plumbers who've worked on everything from century-old cast iron to brand-new PEX systems. We're insured for the job, licensed in NH, and we stand behind every repair with a written warranty.

Experience matters here — a technician who's replaced a hundred water heaters spots the corroded shutoff valve or undersized gas line before it becomes a callback. That's the level of eye we send to every Portsmouth job.

Training doesn't stop after licensing. Our Portsmouth team runs regular refreshers on code updates, new fixture technology, and the material mix specific to Portsmouth, NH construction, so a repair holds up to inspection, not just to a quick test run.

These are the patterns our Portsmouth dispatchers hear about most right before a job turns into an emergency call.

Our Core Services

The Water Heater Replacement Work We Handle Most in Portsmouth, NH

01

Emergency Plumbing

A burst supply line or an overflowing toilet doesn't care what time it is, and neither do we. Our emergency crews carry shutoff tools, wet-vacs, and common repair parts so most emergency calls in Portsmouth are resolved in a single visit.

02

Residential Plumbing

Faucet replacements, garbage disposal swaps, toilet installs, and whole-house re-pipes — our residential division works on the full range of what a Portsmouth home needs, not just the easy jobs.

03

Commercial Plumbing

Restaurants, offices, and retail spaces in Portsmouth, NH can't afford extended downtime over a plumbing issue. Our commercial team is equipped for grease trap service, backflow testing, and multi-fixture repairs on a schedule that respects your operating hours.

04

Drain & Sewer Service

Slow drains, recurring clogs, and sewer backups get diagnosed with real equipment — camera inspection and hydro-jetting — not guesswork. We'll show you exactly what's happening in the line before recommending a repair.

05

Water Heater Repair & Install

We repair and install both traditional tank and tankless water heaters, and we'll walk you through sizing so you're not overpaying for capacity you don't need.

06

Leak Detection & Repair

We use electronic leak detection to pinpoint the source before any demolition starts, so the repair stays focused instead of turning into a bigger project than it needs to be.

07

Fixture Installation & Repair

Whether it's a single kitchen faucet swap or a full bathroom remodel's worth of fixtures, our team handles the rough-in and finish work in one visit where possible.
