What our sink installation includes
Every sink install is different, but here's what's typically covered when we do the work.
Work order
Sink Installation- Old sink removal: We disconnect the supply lines, cut the P-trap loose, and remove the old basin. If it's caulked down, we cut the seal carefully so the countertop doesn't chip. We can haul the old sink away if you want.
- New sink fitting and sealing: We test-fit the new sink, adjust the opening if needed, and set it with plumber's putty or silicone. Mounting clips are tightened evenly so the rim seats flat and doesn't crack under pressure.
- Drain and supply connections: We install the drain assembly, connect the P-trap, and hook up hot and cold supply lines with new washers and Teflon tape. Every threaded joint gets tightened and checked.
- Faucet installation if needed: If you're adding a new faucet, we install it as part of the job. We work with Moen, Delta, and Kohler fixtures and connect everything so it's tested together with the sink.
- Leak testing and cleanup: We fill the basin, let it drain, and watch every joint under full pressure. Any drip gets fixed before we leave. Then we dry the cabinet, wipe the counter, and walk you through what we did.

What sink installation longview WA actually involves
A sink that's set level and sealed tight protects your cabinet and saves you from water damage. We measure, fit, connect, and test so the job holds up.
Sink installation longview WA is the process of removing an old basin, fitting a new one to the countertop, and connecting the drain, supply lines, and faucet so everything drains and seals correctly. We cut or adjust the opening, set the sink in plumber's putty or silicone, and torque the mounting clips evenly so the rim doesn't crack. Underneath, we connect the P-trap, tighten the supply lines, and run water through the system before we call it done.
Most calls we get in Longview start the same way: a homeowner is remodeling a kitchen, replacing a cracked basin, or upgrading to a deeper sink that fits their pots. Older homes around Cowlitz County often have undersized cabinets or corroded shutoff valves that need attention before the new sink goes in. If you've been searching for sink installation in longview WA near me, we can usually get eyes on the job within a day or two.

How our sink installation process works
We keep it simple: show up on time, protect your kitchen, do the work, and clean up before we leave.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
Cuts copper pipe cleanly for supply line modifications. A clean cut means a proper solder joint or compression fitting that won't leak.
For connecting PEX tubing when we reroute supply lines. PEX is common in newer Longview homes and is faster to work with than copper.
Used for copper pipe connections when we need to extend or reroute a supply line. We protect nearby wood and insulation with a heat shield.
Clears clogs in the trap and branch line before we finish the install. A new sink won't drain right if the line behind it is blocked.

How sink installation works in Longview
Longview homes range from early-1900s bungalows near Downtown to newer builds out toward Longview Heights, and the plumbing varies just as much.

PhotoRusted kitchen sink in Downtown Longview
Before: A 20-year-old kitchen sink had rusted through the bottom and was leaking into the cabinet. The shutoff valves were frozen, and the P-trap was corroded. The homeowner was using a bucket under the sink to catch drips.
After: We replaced the sink with a new stainless steel drop-in, swapped the angle stops for quarter-turn ball valves, and installed a new PVC P-trap. The cabinet floor was dried and treated. Total job time was about three hours.
Bathroom vanity upgrade in Longview Heights
Before: A pedestal sink in a small bathroom left no storage and the drain was slow. The supply lines were original and showed signs of corrosion. The homeowner wanted a vanity with a new sink and faucet.
After: We removed the pedestal sink, installed a new vanity with a Moen faucet, and connected a new drain and P-trap. The supply lines were replaced with braided stainless. The drain was snaked to clear a hair clog. Job took four hours.
Rental kitchen sink replacement in Spring Hill
Before: A rental unit had a stained, scratched kitchen sink and a faucet that dripped constantly. The property manager needed it fixed between tenants and wanted it done in one visit.
After: We removed the old sink and faucet, installed a new stainless sink and Delta faucet, and replaced the drain assembly. The old fixtures were hauled away. The unit was ready for the next tenant the same afternoon.
Sink problems we fix for Longview homeowners
A failing sink doesn't fix itself. Here are the most common issues we see in Longview and how we solve them.
Cracked or rusted sink basin
A cracked basin can leak into the cabinet below, causing mold, warped wood, and water damage that costs far more to repair than the sink itself.
Leaking drain or P-trap
A slow drip under the sink can rot the cabinet floor over months. It also attracts pests and can stain whatever you're storing under there.
Corroded shutoff valves
Old angle stops often seize or weep when you try to turn them.
Sink that won't drain properly
Standing water in the sink usually means a clog in the trap or the branch line.
Why a proper sink install matters
A sink that's set level, sealed tight, and plumbed correctly saves you from water damage, mold, and repeat repairs.
No leaks, no callbacks
We pressure-test every connection before we leave.
Correct fit for your countertop
Undermount, drop-in, farmhouse, or bar sink, each one needs a different cut and mounting method.
Code-correct plumbing underneath
Washington State plumbing code requires proper venting, trap arms, and backflow protection on fixtures.
Faster than a DIY weekend
A standard sink swap takes us two to four hours.

What Longview customers say
We had a 20-year-old kitchen sink that was rusting through. Longview Riverbend came out, measured the opening, and had a new one in by lunch. They replaced the angle stops while they were under there, which I appreciated. No leaks, no mess, and they hauled the old sink away.
I called about a bathroom sink installation and they got me on the schedule the next day. The technician showed me the old drain was corroded and replaced it on the spot. He tested everything twice before he left. The price was exactly what they quoted over the phone.
We manage several rentals in Longview and use Longview Riverbend for sink replacements between tenants. They're quick, they clean up, and they don't leave surprises on the invoice. The last one was a kitchen sink swap that took about three hours. Tenants were happy, and so were we.

(360) 886-3111The price depends on the sink type, whether the cabinet needs modification, and how accessible the plumbing is. We give you a flat quote before we start, so you know the number going in.
You can, but most homeowners run into trouble with the drain seal, the supply line torque, or a countertop cut that's slightly off. A drop-in sink is more forgiving than an undermount, which needs precise mounting and often reinforcement. If you're not comfortable working with supply lines and P-traps, it's cheaper to have us do it once than to fix a leak later.
