What is included in a sink visit
Every sink call covers the fixture and the connections that feed and drain it.
Work order
Sink Installation and Repair- Full under-cabinet inspection: We check the P-trap, supply lines, angle stops, disposal flange, and the cabinet floor for soft spots. That inspection is where most hidden leaks get caught before they rot the cabinet base.
- Drain and supply reconnection: New or repaired sinks get fresh supply lines, a properly sized P-trap, and sealed threaded joints with Teflon tape and pipe dope where the fitting calls for it.
- Basin setting and sealing: Drop-in and undermount basins get set in plumber's putty or silicone, leveled, and clamped evenly so the sink does not rock and water does not seep under the rim.
- Faucet and disposal hookup: We connect the faucet supply lines, set the sprayer, and wire the disposal if one is present. Cartridge replacement is included when the faucet is leaking from the handle.
- Pressure and drain testing: We fill the basin, pull the stopper, and run the disposal while watching every joint. Nothing gets signed off until the drain flows and the connections stay dry under load.
- Old fixture haul-away: The old basin, faucet, and disposal come out with us. You are not left with a porcelain sink sitting in the garage waiting for a bulk pickup day.

What sink installation and repair charleston SC involves
A sink that leaks or backs up costs you more the longer it sits. Fixing the cause once, with the right parts and a proper test, is cheaper than patching it twice.
Sink installation and repair charleston SC covers the full job of setting, sealing, and connecting a kitchen or bathroom sink so it drains clean and stays dry. That means cutting or adapting the countertop opening, fitting the basin, setting the drain and strainer, connecting the P-trap and supply lines, and checking every joint under pressure. We also handle the smaller parts that fail first: the faucet cartridge, the shutoff valve, the basket strainer, and the disposal flange.
Charleston homes deal with hard water, older cast iron drains, and humidity that works on metal fittings year-round. A sink that drips under the cabinet in West Ashley or backs up in a Mount Pleasant kitchen usually points to a worn gasket, a corroded pipe, or a partial clog in the branch line. If you are searching for sink installation near me charleston SC, we cover the Peninsula to Johns Island and can often schedule same day sink replacement charleston SC when the old basin has cracked or rusted through.

How our sink service runs
You get a clear sequence from the first call to the final test. Here is what actually happens when we show up at your door.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
Clears grease and scale from kitchen branch lines that a snake cannot fully open. It scours the pipe wall instead of just punching a hole through the clog.
The basin wrench reaches the mounting nuts behind a sink where a standard wrench will not fit. Both stay on the truck for every sink call.
Used when we replace a supply line run in PEX tubing. It makes a permanent, code-compliant crimp connection at the fitting.
When water shows up under a sink but no fitting is wet, this finds the source inside the wall or under the floor before we open anything up.

How sink work runs in Charleston
Charleston's housing stock splits into two problems. On the Peninsula, you have homes from the 1800s and early 1900s with cast iron drains, galvanized supply lines, and wall-hung lavatories that were never designed for modern fixtures.
Harleston Village
Older homes with cast iron drains and wall-hung sinks. We regularly replace corroded drain assemblies and add proper venting where the original plumbing skipped it.
Daniel Island
Newer construction with PEX and PVC. Most calls here are undermount sink installs during remodels or faucet cartridge failures from hard water scale.
West Ashley
1970s and 1980s homes with copper supply lines that are now pinhole leaking. Sink calls here often turn into a supply line replacement.

PhotoKitchen sink leak stopped in West Ashley
Before: A 1980s West Ashley home had water pooling in the cabinet under the kitchen sink for weeks. The cabinet floor was soft, the basket strainer gasket was shot, and both supply lines were corroded at the shutoff valves.
After: We replaced the basket strainer, both supply lines, and the angle stops, then pressure-tested with the basin full and the disposal running. The cabinet floor was dried and the leak was gone. Total time on site was about two and a half hours.
Undermount sink installed in Mount Pleasant
Before: A Mount Pleasant kitchen had a drop-in sink that was rusting through at the rim, with water seeping under the countertop edge. The homeowner had already bought a new undermount basin and wanted it installed in the existing quartz.
After: We cut the countertop opening to match the new basin, set it with proper clips and silicone, and reconnected the disposal and P-trap with new supply lines. The sink sits level and sealed, and the old basin came out with us.
Recurring bathroom backup cleared in North Charleston
Before: A North Charleston rental had a bathroom sink that backed up every few weeks. The tenant had been pouring drain cleaner down it for months, and the slow drain was getting worse instead of better.
After: We cameraed the branch line, found heavy scale and hair buildup past the trap, and cleared it with a drain snake and hydro jetter. The trap seal was corrected and the venting was checked. The sink has drained normally since.
Sink problems we fix before they get worse
Most sink issues start small and get expensive. A drip that looks harmless can rot a cabinet base in a season.
Water pooling in the cabinet under the sink
Cabinet floors swell, particle board crumbles, and mold takes hold in a space you rarely look at.
Sink drains slowly or backs up repeatedly
Standing water in a kitchen sink is a health issue and a sign the branch line is partially blocked.
Cracked or rusted basin that cannot be patched
A cracked porcelain or rusted steel sink will keep leaking no matter how much sealant goes on it.
Faucet drips and the handle feels loose
Ignoring it can score the valve body and turn a cheap repair into a full faucet replacement.
Why homeowners call us for sink work
A sink problem is rarely just about the sink. Water finds the cabinet floor, the drywall, and the framing behind it.
Stop leaks at the source
A kitchen sink leak repair charleston call usually traces back to a failed basket strainer gasket, a loose slip nut, or a cracked tailpiece.
Same-day replacement options
Cracked porcelain and rusted steel basins cannot be patched.

What Charleston customers say
Our kitchen sink had been dripping into the cabinet for weeks and I kept putting it off. They found a cracked basket strainer gasket and a loose slip nut, replaced both, and tested it with the basin full. Two hours total. The cabinet floor is dry for the first time since we bought the house.
We wanted a new undermount sink in the kitchen and had already bought the basin. They cut the countertop opening, set it level, and reconnected everything including the disposal. Clean work, no mess left behind, and the price matched the quote exactly. Would call them again for the bathroom sink next.
I manage several rentals and sink calls come up constantly. They handled a bathroom sink repair at one unit and a full replacement at another in the same week. Both tenants were happy, and I got photos of the finished work without asking. That saves me a trip across town.

Still have a question?
Describe what you are seeing and we will point you to the right next step.
(854) 226-6111The price moves with the basin type, whether the countertop opening needs cutting, and whether the shutoff valves and P-trap need replacing while we are in there. We quote it in writing before we start.
Shut the water off at the angle stops first, then dry the area and watch where the water reappears. Most leaks come from the basket strainer gasket, a loose slip nut on the P-trap, or a failed supply line. If the leak is at the wall or the cabinet floor is soft, call us, because that usually means a corroded pipe or a drain issue behind the cabinet.
