About this service

Washer and dryer installation Rockville MD, start to finish

Washer and dryer installation Rockville MD is the licensed hookup, leveling, venting, and testing of a new laundry pair so it runs without leaks, shakes, or code violations. We connect the hot and cold water inlet valves, secure the drain hose to the standpipe or laundry sink, install the dryer vent with rigid or semi-rigid duct, and confirm the machine sits level on the floor. Then we run a full cycle and check every joint with a leak detector before we pack up.

Most Rockville homes we service were built between the 1950s and the 2000s, and laundry rooms in Twinbrook, Lincoln Park, and Rockville Heights often have tight closets, shallow pans, or older standpipes that need adapting. If you have been searching for a Rockville washer dryer installation company that actually shows up on time, we schedule two-hour arrival windows and call ahead. We also handle new washer and dryer hookup Rockville MD jobs in condos and apartments where the shutoff valves are behind a panel.

  • ✓ Same-day slots available
  • ✓ Leak and vent tested
  • ✓ Stackable and tight-space work
  • ✓ Old unit hauled away
What's included

What our washer and dryer installation includes

Every install covers the full hookup and a live cycle test. Add-ons like haul-away, new hoses, or a vent rebuild are quoted upfront so you know the total before we start. Here is what is in the standard package.

01
✓

Water line hookup

New braided stainless hoses connect the hot and cold water inlet valves to the washer. We check every fitting with a leak detector and confirm the shutoff valves turn freely. If a valve is seized, we replace it before it becomes a flood.

02
✓

Drain and standpipe

The drain hose is secured to the standpipe or laundry sink with a proper air gap and clamp. We confirm the standpipe is tall enough to prevent backflow and that the drain runs freely before the first cycle.

03
✓

Dryer vent installation

We install rigid or semi-rigid duct, not the foil accordion hose that clogs and becomes a fire risk. The vent run is kept as short and straight as the space allows, and we confirm airflow at the exterior hood.

04
✓

Leveling and vibration check

A torpedo level on all four corners, then a spin cycle to confirm the washer does not walk. Front-loaders get the shipping bolts removed and the drum checked for free rotation. Vibration is the number one complaint on new installs, and leveling fixes it.

05
✓

Electrical and gas check

The dryer circuit is tested with a clamp meter to confirm correct amperage. Gas dryers get a leak test on the supply connection by a tech with Maryland gas appliance licensing. We do not leave until the reading is clean.

06
✓

Full cycle test and walkthrough

We run a complete wash and a 15-minute dry cycle, then walk you through the shutoff valves, the vent cleaning schedule, and the error codes to watch for. Manuals stay in a folder on top of the washer. You get a 1-year workmanship warranty.

How it works

What to expect on installation day

Call or text us with your address, the make and model of the new units, and whether you need the old set removed. We confirm a two-hour arrival window and text you the tech's name. Most Rockville ZIP codes, including 20850, 20851, and 20852, get same-day or next-day availability.

The tech inspects the shutoff valves, the drain standpipe, the dryer vent run, and the outlet. If a valve is seized or the vent is crushed, we tell you before we start and quote the fix. This takes 10 to 15 minutes and prevents a mid-install surprise.

We connect the water inlet valves with new braided hoses, secure the drain hose, install the vent duct, and plug in the dryer. The washer gets leveled with a torpedo level on all four corners. A level washer is the difference between a quiet spin cycle and one that walks across the floor.

We run a full wash cycle and a 15-minute dry cycle while watching for leaks, error codes, and unusual vibration. A clamp meter confirms the dryer is pulling the right amperage on its circuit. If anything reads off, we adjust before we call you in to look.

We show you the shutoff valves, explain how to clean the dryer vent, and leave the manuals in a folder on top of the washer. You get a 1-year workmanship warranty on the install. Payment is due on completion, and we take card, check, or cash.

Tools & methods

Tools and methods we bring to every install

01
✓

Appliance dolly and hand truck

Moves 200-pound washers and dryers without scratching floors, door frames, or stair rails. Essential for basement and second-floor laundry rooms in older Rockville homes.

02
✓

Leak detector

Sniffs every water and gas connection for slow leaks that a visual check would miss. Used on all inlet valves, drain fittings, and gas dryer supply lines before we leave.

03
✓

Clamp meter

Confirms the dryer is pulling the correct amperage on its 240V circuit. A reading outside spec means a wiring issue we need to flag before the unit runs.

04
✓

Multimeter and voltage tester

Traces electrical faults on the washer control board and dryer heating element. Also confirms the outlet is wired correctly before we plug anything in.

05
✓

Torpedo level

Levels the washer on all four corners. A level machine does not walk, does not vibrate the floor, and does not wear out the drum bearing early.

06
✓

Nut driver set and torx screwdriver set

Opens access panels on Whirlpool, GE, Samsung, LG, and Maytag units without stripping screws. Needed for shipping bolt removal and vent connection.

Real results

Before and after.

New Samsung pair in a Twinbrook ranch
Washer and Dryer Installation

New Samsung pair in a Twinbrook ranch

A 1990s Whirlpool washer and dryer sat in a shallow alcove with original rubber hoses and a foil accordion vent that had been crushed against the wall for years. The washer walked two inches during every spin cycle.

After: We replaced the hoses with braided stainless, swapped the foil vent for rigid duct, and leveled the new Samsung pair on all four corners. The spin cycle now runs quiet, and the dryer finishes a load in 45 minutes instead of 90.

Stacked LG unit in a Rockville Town Center condo
Washer and Dryer Installation

Stacked LG unit in a Rockville Town Center condo

The previous stacked unit had been installed without removing the shipping bolts, so the drum banged against the frame on every spin. The shutoff valves were behind a panel and one was seized open.

After: We pulled the unit, removed the shipping bolts, replaced the seized valve, and reinstalled the stack with proper clearance. The drum now spins free, and the noise level dropped enough that the owner can run laundry at night.

Basement laundry room in Woodley Gardens
Washer and Dryer Installation

Basement laundry room in Woodley Gardens

A 30-foot dryer vent run with four elbows had been patched with foil tape for years. The dryer took two cycles to dry a load, and the exterior hood barely opened.

After: We rebuilt the vent run with rigid duct, cut it to 18 feet with two elbows, and replaced the exterior hood. Dry time dropped to a single 50-minute cycle, and the dryer now pulls correct amperage on the clamp meter.

Problems we solve

Laundry problems we solve on install day

Most install calls come from one of these four situations. We handle each one without a second appointment or a separate contractor.

Ask a pro →
01

Old supply hoses burst or weep at the fitting

We replace every old rubber hose with braided stainless on every install, no exceptions. New hoses cost a few dollars and prevent a four-figure water damage claim. We also test the shutoff valves and replace any that will not seat fully.

↗
02

Dryer vent is crushed or routed with foil accordion hose

We replace foil hose with rigid or semi-rigid duct and keep the run as short and straight as the space allows. We confirm airflow at the exterior hood before we leave. If the vent run is long, we tell you and quote a proper rebuild.

↗
03

Washer walks across the floor during spin

We level all four corners with a torpedo level and run a spin cycle to confirm. Shipping bolts come out on every front-loader. If the floor itself is uneven, we use shims rated for the load and check again.

↗
04

Stacked unit will not fit the closet

We measure the closet, the door swing, and the clearance before we move anything. If the space is tight, we remove the door, use a dolly, and slide the unit in from the correct angle. Stackable washer dryer installation Rockville jobs are a routine call for us.
