Bathroom & Kitchen Plumbing

Rough to finish

Bathroom & Kitchen Remodeling Plumbers

Renovation plumbing is half craft and half scheduling. We do the rough-in on time so your tile guy is not standing around, and we come back for the finish when the room is actually ready for us.

Bathroom & Kitchen Plumbing on Long Island, Explained

Open walls are an opportunity

The single best reason to use a real plumber on a renovation is that they tell you what they find. Galvanized supply lines behind a wall you are about to close up are a problem you want to solve now, at the cost of pipe and an hour, rather than in four years at the cost of a ceiling.

The same goes for a cast-iron stack that has scaled to half its diameter, or a vent that was never properly tied in. None of it is expensive while the wall is open. All of it is expensive afterward.

Moving a toilet is not like moving a sink

Sinks and tubs run on relatively small waste lines with a fair amount of routing freedom. A toilet needs a three-inch line at a consistent fall, and that line has to get to the stack.

On a slab or over a finished ceiling, that changes what is possible. We would rather walk your layout at the design stage and tell you what the pipe will and will not allow than get the call after the tile has been ordered.

Working with your contractor

Most of our renovation work runs alongside a general contractor, and we are easy to work with — we hold our dates, we clean up our debris, and we do not leave the site with the water off overnight without telling anyone.

If you are running the project yourself, we will lay out the sequence for you: demo, rough-in, inspection, close walls, tile, then finish plumbing. Getting that order wrong is the most common way a homeowner-run renovation loses three weeks.

Fixtures worth the money

Spend on the valve, not the spout. A quality pressure-balanced shower valve from a brand with parts availability will outlive several trims, and when a cartridge eventually goes we can get one. Bargain-brand valves are the ones we end up cutting out of walls.

Everything downstream of the valve is aesthetics, and you should buy what you like.

Good questions

Bathroom & Kitchen Plumbing: What People Ask Us.

Can you work alongside my contractor?

Most of our renovation work runs that way. We hold our rough-in dates, clean up after ourselves and coordinate directly with the GC so you are not relaying messages between trades.

Can I move my toilet during a bathroom renovation?

Often, but not always. A toilet needs a three-inch waste line at consistent fall back to the stack, and on a slab or over a finished ceiling that limits the options. We will walk the layout with you before anything is ordered.

    Water heater went on a Sunday with a house full of family. Tony was here in an hour and a half, had the tank on the truck, and we had hot water before dinner. Priced it before he started and that was the price.

    Two other companies quoted me for a full sewer replacement. Ray cameraed the line, showed me the footage, and said one joint was the problem. Spot repair, a third of the price. That is a rare thing.

    We flooded twice before we called Flow’s. They put in a proper pit, a real pump and a battery backup, and then fixed the grading outside that nobody else had mentioned. Dry through the last two nor’easters.

    Mike handled the plumbing for our whole kitchen renovation and was the only trade on the job who hit every date. He also caught a galvanized line in the wall that would have been a nightmare later.

    Kitchen sink backed up every few months for years. They jetted the line instead of just snaking it and explained exactly why it kept happening. Two years later, no problems.

    Burst pipe at 11pm in February. A real person answered, told me which valve to shut while they drove over, and stayed until it was dry. I have recommended them to half my block since.

    Converted us from oil to gas and coordinated everything, including the parts that were National Grid’s job. I did not have to chase anybody once. Bills dropped immediately.
