Costanza Plumbing

Gig Harbor Plumber

Plumber in Gig Harbor, WA

Gig Harbor homeowners tend to be particular about who works on their homes — and understandably so. The community has a character worth protecting, and the homes here, whether a restored craftsman near the waterfront or a custom build overlooking Henderson Bay, reflect real investment and real pride. When you need a plumber in Gig Harbor, you want someone who shows up on time, does the work correctly, and doesn’t leave you guessing about what was done or what it cost. That’s exactly what Costanza Plumbing brings to every job in Gig Harbor — licensed work, transparent pricing, and a team that treats your home with the same care you do.

Plumbing Services We Provide in Gig Harbor

From the harbor waterfront out to Artondale and the Key Peninsula, here’s what we handle throughout the Gig Harbor service area:

Plumbing Repairs

Burst pipes, leaking supply lines, running toilets, low water pressure, broken shut-off valves — we diagnose and repair plumbing problems throughout Gig Harbor homes. We provide a written estimate before starting any work, and we don’t recommend repairs you don’t need.

Water Heater Installation & Replacement

Tank or tankless, gas or electric — we install and replace water heaters for Gig Harbor homes. If your unit is showing its age or struggling to keep up with demand, our water heater installation page covers the full range of options and current pricing in the area.

Drain Cleaning In Gig Harbor

Drain Cleaning & Sewer Service

Slow drains and recurring clogs are rarely just surface-level problems. We clear blockages, camera-inspect drain lines, and identify root intrusion or deteriorating pipe before it escalates into a sewer backup. Homes with mature landscaping near the waterfront are especially vulnerable to root intrusion in older clay or cast iron lines.

Whole-Home Repiping

Older homes near Gig Harbor’s waterfront and harbor area carry an additional corrosion risk that inland homes don’t — salt-air exposure works on older pipe fittings and connections over decades. If you’re seeing discolored water, declining pressure, or recurring leaks in a home built before 1980, see our whole-home repiping page for a full assessment guide.

Bathroom & Kitchen Remodel Plumbing

Gig Harbor’s active remodel market means we work regularly alongside local contractors and designers on bathroom and kitchen projects. Whether you’re moving fixtures, upgrading to a walk-in shower, or reconfiguring a kitchen around a new island layout, our remodeling plumber team coordinates directly with your GC to keep plumbing off the critical path.

New Construction Plumbing

The custom home market on the Gig Harbor peninsula — from Canterwood to the bluff properties overlooking the Sound — keeps new construction work active year-round. We provide complete new construction plumbing from underground rough-in through finish trim, coordinated with your build schedule and general contractor.

What Makes Gig Harbor Plumbing Different

Working in Gig Harbor isn’t the same as working anywhere else in Pierce County. The community’s mix of historic waterfront homes, mid-century neighborhoods, and newer custom construction creates a wide range of plumbing conditions within just a few square miles.

The homes closest to the harbor and the Narrows — particularly older properties in the Vernhardson Street corridor and the streets running down toward the marina — see accelerated external corrosion on pipe fittings and shutoff valves from decades of salt-laden air. These homes often need more thorough assessment before remodel or repair work begins, because what looks like a simple fixture swap can open up a much larger condition issue underneath.

Out toward Rosedale, Artondale, and the newer construction areas off Borgen Boulevard and Wollochet Drive, you find homes with more modern plumbing systems but active remodel and expansion demand as families grow into and update their properties. New bathroom additions, expanded kitchens, and ADU construction are common requests in these neighborhoods.

Fox Island is its own consideration — bridge-connected but logistically distinct, with homes primarily on well and septic systems that have specific requirements and inspection processes separate from Gig Harbor city-connected properties. We work on Fox Island regularly and understand the difference.
