The installation process
We start by running or connecting the hot and cold supply lines to your washer's location, then set up the standpipe and drain connection so wastewater has a clear path out. If you're adding a laundry sink, we tie that into the same drain system.
We also check that the washer's drain line is sized and vented correctly — an undersized or poorly vented drain is one of the most common reasons a laundry room floods during the spin cycle. Once everything's connected, we run a full cycle to confirm it drains cleanly before we call the job done.

What affects the cost
A laundry room in a spot with existing plumbing nearby is a simpler job than one being added somewhere new, which requires running supply and drain lines further. Whether you're also adding a utility sink, and how accessible the space is, both factor into the price.
We'll look at your space and give you a clear number before we start any work.
Laundry room plumbing in Armonk's older housing stock
A lot of the calls we get aren't about relocating an existing laundry setup — they're about homes built decades ago that were never plumbed for one in a convenient spot to begin with. Older Armonk-area houses often tucked laundry into a mudroom, an upstairs closet, or wherever there happened to be room, with a supply line and drain that were adequate for the era but awkward by today's standards. Adding or upgrading a laundry hookup in one of these homes usually means running genuinely new supply and drain lines, not just connecting to something that's already there.
Wherever the space ends up — a finished basement, a converted closet, or a first-floor mudroom — the drain line has to route somewhere that can actually handle gravity flow, or connect to a pump system if it can't. We plan that out before any walls go up around it. If you're still in the planning stage, this laundry room layout guidance is a helpful starting point for thinking through where plumbing needs to go before construction begins.
If the space you're finishing is below grade, it's worth also asking about protecting a finished basement with a sump pump while the space is already open.
Avoiding leaks and backups
Most laundry room plumbing problems come from a standpipe that's too short, a drain line that's undersized, or a supply line connection that was never fully tightened. Getting these details right during installation is what keeps you from finding water on the floor later.
If you're setting up the room from scratch, it's also a good time to think about installing a new sink in your home for the space, or connecting a new washing machine or dishwasher if you're replacing appliances at the same time.

Frequently asked questions
Can you relocate my laundry room to a different part of the basement?
Yes. We run new supply and drain lines to the new location, which is common during basement-finishing projects.
Why does my washer's drain back up during the spin cycle?
It's usually a standpipe that's too short or a drain line that's undersized for the volume of water being pushed out. We can diagnose and correct this.
Do you install laundry sinks?
Yes, we can add a laundry sink and tie it into the same drain system as your washer.
What causes a leak behind the washing machine?
Most often it's a loose supply line fitting or a worn hose connection. We check both during installation and can repair an existing leak as well.
Do basement laundry rooms need a special drain setup?
Sometimes. Depending on your basement's layout, the drain may need to route to a spot that handles gravity flow correctly or connect to a pump system. We assess this before starting the work.
How long does a laundry room plumbing installation take?
It depends on whether we're connecting to existing lines or running new ones. We'll give you a specific timeline once we've seen the space.
