Kitchen Plumbing in Winthrop, ME
Sink, faucet, dishwasher and disposal work done right the first time — by Augusta's family-owned plumbers.
Kitchen Plumbing for Winthrop Homeowners
RJC Plumbing handles kitchen plumbing for homeowners throughout Winthrop. We run out of Augusta, so response times stay quick and every job benefits from already knowing the local housing and permitting.
From sink installations and dishwasher hookups to garbage disposal replacements and faucet upgrades, RJC Plumbing handles all your kitchen plumbing needs with expert craftsmanship and attention to detail.

What kitchen plumbing work do we handle in Augusta?
Most kitchen calls are about the sink: a dripping faucet, a slow drain, a disposal that hums but will not spin, or a dishwasher that was never connected properly. We repair or replace all of it, usually in one visit.
We also handle the plumbing side of kitchen remodels — moving supply and drain lines for a new island, adding a pot filler, or roughing in a second sink — and coordinate with your cabinet installer so nothing waits on us.
Fixture upgrades are common in the older homes around Augusta, Hallowell and Gardiner. Swapping worn shut-off valves and supply lines while a new faucet goes in prevents the leaks that show up later under the cabinet.
Why is my kitchen sink draining slowly?
Grease, coffee grounds and food scraps build up in the trap and the horizontal drain line behind the wall. A disposal that is not flushed with cold water makes it worse. We clear the whole line, not just the trap.
If the drain gurgles or backs up when the dishwasher runs, the cause is usually a blocked air gap, a kinked drain hose or a partly clogged branch line. All three are quick fixes once diagnosed.
Should I repair or replace a leaking kitchen faucet?
A cartridge or seal on a quality faucet is worth replacing. A builder-grade faucet that is more than ten years old, corroded at the base or leaking from the spout usually costs about as much to rebuild as to replace.
We carry common cartridges and supply lines on the truck, so many faucet repairs are finished on the first trip. For replacements, we are happy to install a fixture you have already purchased.
Garbage disposal and dishwasher hookups
Disposal installs include a new mounting assembly, a properly pitched discharge, and a dishwasher connection with the knockout removed — a step that is often missed and leaves the dishwasher unable to drain.
For dishwashers we install the supply valve, route the drain with a high loop or air gap, and confirm the electrical connection is in place before we leave, so the first cycle runs without a puddle.

Why Winthrop Chooses RJC Plumbing
- We know Winthrop's housing and infrastructure because we work here routinely
- A written, upfront price — no surprises on the invoice
- Urgent calls do not wait behind routine ones on our schedule
- Licensed, insured, and background-checked, with a real person answering the phone
Winthrop's Homes and Plumbing
We also serve Manchester and Augusta along the same Route 202 corridor. See all of our Central Maine service areas or call for a free estimate.
Census figures count more than 600 Winthrop homes held for seasonal use. Camps need two visits a year: opening in spring, when fixtures that sat all winter get checked for split lines and leaking valves, and winterizing in fall, when the system is drained so nothing freezes. We handle both, along with the fixture repairs that turn up, as part of our bathroom and camp plumbing service, and urgent leaks go to our emergency repair team.
Family-Owned, Not a Franchise
RJC Plumbing answers to Winthrop homeowners directly — a small, family-owned crew, not a franchise office somewhere else. The company is small enough that the person who quotes the job is often the one who does it. We would rather earn the next call than upsell this one.

Codes & Permits for Kitchen Plumbing in Winthrop
In Winthrop, plumbing permits come from the Local Plumbing Inspector at the Winthrop Code Enforcement Office (17 Highland Avenue, Winthrop, ME 04364, 207-377-7200 ext. 6007). With 6,121 residents, Winthrop is required to enforce the Maine Uniform Building and Energy Code (MUBEC).

- The Maine Plumbers' Examining Board (within the Office of Professional and Occupational Regulation, Department of Professional and Financial Regulation) licenses plumbers statewide and maintains the plumbing rules and laws (Title 32, Chapter 49); day-to-day permit issuance and inspection for a given town is carried out locally by a Local Plumbing Inspector (LPI), who is often the same person as the municipality's Code Enforcement Officer. maine.gov
How RJC Plumbing Handles Kitchen Plumbing in Winthrop
- Winthrop's housing stock runs old enough (median year built 1977) that a kitchen plumbing job often turns up a mix of pipe eras in the same house — we tell you plainly which sections are sound and which ones are due.
- Winthrop Utilities District supplies most of Winthrop from Narrows Pond, with Maranacook Lake as backup; on a kitchen plumbing job we work fixture by fixture on your side of that meter.
- We file for a permit at the Winthrop Code Enforcement Office whenever the work calls for one, to the current 2021 Uniform Plumbing Code.

Kitchen Plumbing Questions from Winthrop Homeowners
Do you install faucets and sinks that I bought myself?
Yes. Have the fixture on site and we will install it, including new supply lines and shut-off valves if yours are worn. We will tell you up front if a fixture is not a good fit for your sink.
Can you replace my garbage disposal the same day?
Often, yes. Standard 1/2 and 3/4 HP disposals are common stock, and a like-for-like replacement typically takes about an hour. Call in the morning and we will do our best to fit it in.
Why does my dishwasher leave standing water?
Usually a drain hose without a high loop, a clogged air gap, or a disposal knockout plug that was never removed at install. We check all three, then the pump and filter, and fix it in one visit.
Do you handle the plumbing for a full kitchen remodel?
Yes. We rough in new supply and drain locations, relocate lines for islands and second sinks, and return for trim-out once cabinets and counters are set. We coordinate directly with your contractor or cabinet installer.
Which towns do you cover for kitchen plumbing?
Augusta, Hallowell, Gardiner, Farmingdale, Manchester, Winthrop and Waterville, plus the surrounding Kennebec County towns. If you are unsure, call and we will tell you right away.
Is there a charge for a kitchen plumbing estimate?
No. Estimates are free and there is no obligation. For small repairs we can usually quote over the phone and confirm the price on arrival before starting.
