Toilet runs continuously
Usually a worn flapper or a misadjusted fill valve. Inexpensive to fix and one of the largest sources of invisible water waste in a home.
Repairs & installs
The small jobs still deserve someone who shuts the water off at the right valve.

Not every plumbing call is a crisis. A lot of what we do is the ordinary work of keeping a house functioning — a toilet that runs all night, a faucet that has dripped for a year, a shutoff valve seized solid at exactly the moment you need it.
These are worth handling promptly for a practical reason: a running toilet can waste more water in a month than most people expect to see on a bill, and a shutoff valve that will not turn converts a minor leak into an emergency.
Symptoms
Usually a worn flapper or a misadjusted fill valve. Inexpensive to fix and one of the largest sources of invisible water waste in a home.
Worn cartridge, seat, or O-rings. Dripping is a cartridge issue; water appearing around the base is usually a failing seal beneath the handle.
Typically a clogged aerator or a partially closed angle stop, not a house-wide pressure problem. Quick to diagnose.
Old multi-turn angle stops seize with mineral deposits. Worth replacing proactively — you find out they are stuck at the worst possible moment.
A failed wax ring or loose closet bolts. Left alone, water gets under the flooring and the subfloor becomes part of the job.
Our process
You get a flat price before work starts, including parts. No hourly clock.
A quality faucet with a worn cartridge should be rebuilt, not replaced. We will tell you when a fixture is genuinely past the point of being worth repairing — and when it is not.
We test the shutoff serving whatever we are working on. A seized angle stop is worth catching now rather than during a leak.
Floor protection goes down, old parts leave with us, and the work area is left as we found it.
Scope
Small jobs are flat-rate and quoted up front. If you have several minor items, mention them when you book — handling them in one visit costs less than three separate trips.
Request serviceIf it is a decent-quality fixture and the finish is still good, a cartridge rebuild is usually the better spend and takes less time. Budget fixtures with worn finishes and multiple failures are generally better replaced. We will give you our honest read on which yours is.
Considerably more than people assume — a continuously running toilet can waste hundreds of gallons a day. It is often the explanation for a water bill that jumped without any other change.
Yes, that is common and we are happy to. One caution: we cannot warranty the fixture itself, only our installation. If a homeowner-supplied unit arrives defective, the replacement comes from your supplier.
We take them. There is a standard service call charge that covers the visit, and the work is quoted on top of it — which is why grouping several small items into one visit is worth doing.

Upon hearing my water heater hissing for 20 minutes, I called Alexander Plumbing. They were able to send someone out within the hour to inspect it. Then they were able to replace the water heater early the next morning…
My kitchen drain was backing up and I have long pipes to get to the main stack- Paul was able to get enough length to free up the clog. He also used a chemical to super fulsh the pipes. Great service- Paul was very good…
Pat and Neil are absolutely fantastic. We had a bit of an emergency plumbing issue and they were so calm and informative on the phone. Neil was at our home within an hour and did excellent work! Definitely recommend…
If it is safe, close the nearest shutoff valve, move belongings away from water, and tell us exactly what you see.
