Washer & Dryer Hookup (Existing Connections)

A washer and electric dryer hookup from Handis connects a new washer and electric dryer to the existing hot and cold supply hose bibs, the existing standpipe drain, the existing 120V washer outlet, the existing 4-prong 240V dryer outlet, and the existing vent duct — from $200 for a single unit, with new stainless-braided washer hoses and a semi-rigid aluminum dryer vent transition included by default. A set delivered to the laundry room with the cords coiled on top is the easiest appliance install in the kitchen-and-laundry list — if the existing connections are sound. They usually are not. The rubber washer hoses from the original install are 15 or 25 years old and on the short list of top homeowner-flood causes. The 240V dryer outlet is the 4-prong modern code but is sometimes the older 3-prong configuration that needs a new dryer cord pigtail. The dryer vent is full of lint and may have a crushed transition piece behind the wall. Handis sends a vetted handyman who replaces the rubber washer hoses with new stainless-braided hoses on every install as a default, verifies the 240V outlet reads 240V before plugging in, and cleans the vent transition if it is reachable. Existing hot/cold supply, existing standpipe, existing 120V and 240V outlets, existing vent — new circuits, new plumbing, new vent runs, and gas dryers route to a licensed Washington L&I contractor.

What Does a Washer and Electric Dryer Hookup Include?

A washer and electric dryer hookup from Handis is a four-step install — pre-install inspection of supply, drain, 240V outlet, and vent; washer hookup with new stainless-braided hot/cold hoses by default; 240V outlet check with a 3-prong-to-4-prong cord pigtail conversion if needed; vent transition to semi-rigid aluminum; and a five-minute fill-and-drain plus high-heat test on both units. The connections have to exist (the hot/cold supply hose bibs, the standpipe drain or laundry sink, the 120V washer outlet, the 4-prong 240V dryer outlet, and the vent duct) and have to be sound. New circuits, new plumbing, new vent ductwork, and gas dryers all route to a licensed contractor.

Pre-Install Inspection

Test the hot and cold supply hose bib shutoffs — each should turn cleanly through 90 degrees and seat fully. Look at the existing rubber washer hoses for age and bulges (they are almost always due for replacement). Check the standpipe drain for depth (most code requires 18 to 30 inches above the floor) and free flow with a quick water test. Read the 240V dryer outlet with a meter — should be steady 240V across the hot legs and steady 120V to neutral on each. Look at the dryer vent for lint accumulation and crushed transitions. About 15 minutes.

Washer Hookup

Pull the old washer (if present) onto a moving blanket. Disconnect the old supply hoses, the standpipe drain hose, and the 120V cord. Slide the new washer into position. Install new stainless-braided hot and cold supply hoses with PTFE tape on the male threads and a hand-tighten-plus-a-quarter-turn with the wrench. Connect the new drain hose to the standpipe (or hook over the edge of the laundry sink) with the drain riser bracket if the cabinet does not have one — the drain has to rise to at least the recommended height before dropping to prevent siphoning. Plug into the 120V outlet. Level the washer feet (a tilted washer walks across the floor on the spin cycle). Run a 5-minute fill-and-drain cycle to verify no leaks. About 30 to 45 minutes.

Electric Dryer Hookup

Pull the old dryer (if present). Disconnect the 4-prong cord from the old unit (or the 3-prong if the outlet is the older configuration — modern dryers ship for 4-prong by default and need a 3-prong pigtail conversion if your outlet is 3-prong). Disconnect the vent duct. Slide the new dryer into position. Install the dryer cord on the new unit per the manufacturer instructions (the cord is shipped separate; this is normal). Connect the vent duct with a transition clamp — semi-rigid aluminum is the preferred transition, not the white plastic accordion which is a fire hazard under code. Plug into the 240V outlet. Run a 5-minute high-heat cycle to verify airflow and temperature. About 30 to 45 minutes.

Process

How a Washer and Electric Dryer Hookup Works

Five sequential steps from the laundry-room inspection to the high-heat dryer test — the actual sequence we follow on every washer and electric dryer install on existing connections.

Pricing

Washer & Dryer Hookup Pricing

Final pricing depends on whether you are installing one unit or both, the existing connection condition, and whether your dryer outlet is 4-prong (modern) or 3-prong (older). New stainless-braided washer hoses are included by default. Gas dryers are not within this trade and route to a licensed contractor. Request a free estimate for an accurate quote.

Send us the new washer and dryer models, a photo of the existing supply hoses and the 240V outlet — we will quote the visit and tell you upfront if anything routes to a licensed contractor.

Why Homeowners Book Handis for Washer & Dryer Hookups

Why Homeowners Book Handis for Washer & Dryer Hookups

Most laundry-room install calls fail one of three ways — the old rubber washer hoses burst within months of the new washer install (the homeowner is shocked but the hoses were already 20 years old), the 240V dryer outlet turns out to be a 3-prong configuration and the new dryer ships with a 4-prong cord that needs the pigtail swap, or the dryer vent has a white accordion transition behind the wall that is a documented fire hazard and a code violation under modern requirements. After a few hundred laundry installs across Seattle homes, every one of these has a check at the start of the visit. We replace old rubber hoses as a default (it is in the base price, not an upsell), we convert 3-prong to 4-prong cord pigtails when needed, and we replace the white accordion with semi-rigid aluminum on every dryer install.

Existing connections only, and we say so on the call

This is a plug-in hookup on the connections already in the laundry room. New circuits (240V or 120V), new water supply lines, new drain runs, new vent ductwork, and gas dryers all route to a licensed Washington L&I contractor. A gas dryer hookup specifically requires a licensed gas-fitter; we do not run gas, do not connect a gas dryer's flexible gas connector, and we tell you on the booking call when the request is gas instead of electric.

New stainless-braided washer hoses by default

Old rubber washer hoses are one of the top causes of homeowner water damage — they look fine, they hold pressure for years, and then they burst at three in the morning. Insurance industry data tracks washer-hose failure as one of the most expensive single appliance-related claim categories. We install new stainless-braided hoses on every washer hookup as a default, not as an upsell — the cost is in the price of the visit.

3-prong to 4-prong pigtail conversion when needed

The 4-prong dryer outlet (with a dedicated ground) became the national code in 1996. Many laundry rooms wired before then are still 3-prong. New dryers ship with a 4-prong cord by default. The conversion is a swap of the cord on the dryer itself (the cord is field-replaceable and the conversion is part of the manufacturer-allowed install method) — not a rewire of the outlet. We bring the 3-prong cord, swap the new dryer's cord, and the dryer runs on the existing 3-prong outlet. If you want the outlet itself upgraded to 4-prong, that routes to a licensed electrician.

Semi-rigid aluminum vent transition, not white accordion

The white plastic accordion vent transition is a fire hazard and a code violation under modern requirements (IRC and most local jurisdictions require semi-rigid metal). The accordion traps lint in the ridges and can ignite from the high heat of a dryer cycle. We replace any accordion transition with semi-rigid aluminum on every dryer install — the cost is in the base price, not an upsell. The dryer vent itself (the duct behind the wall) is the homeowner's existing infrastructure; we transition cleanly into it.

Insured, background-checked, 30-day workmanship guarantee

If a hose we installed leaks, a vent transition slips, a drain hose dislodges from the standpipe, or any connection we made fails within 30 days due to our workmanship, we come back and fix it at no extra charge. The guarantee covers our work — it does not cover the new appliance's manufacturer warranty (motor, drum, control board, internal failures file with the manufacturer), and it does not cover pre-existing failures we flagged before the install (a cracked standpipe, a corroded hose bib, a clogged dryer vent past the transition).

Estimate

Tell us the new washer and dryer models (or a single unit), the existing 240V dryer outlet style (3-prong or 4-prong), a photo of the existing supply hoses and the vent transition, and whether your laundry has a standpipe drain or a laundry sink. We will quote the visit and tell you upfront if anything routes to a licensed contractor.

FAQ

Frequently Asked Questions

Common questions about washer and dryer hookup — pricing, scope, what we replace by default, and what routes to a licensed contractor.

How much does a washer and dryer hookup cost?
A single washer hookup on existing connections is $200, including new stainless-braided supply hoses by default. A single electric dryer hookup on the existing 4-prong 240V outlet is $200, including a semi-rigid aluminum vent transition. A washer-plus-electric-dryer set on the same visit is $400. A 3-prong to 4-prong cord pigtail conversion (when your dryer outlet is the older 3-prong configuration) is $60 per dryer. A new standpipe drain riser bracket (when the cabinet does not have one) is $40. A stackable set lift (dryer on top of washer) is $80. Gas dryer hookups are not within this trade and route to a licensed Washington L&I contractor.
Why does Handis NOT do gas dryers?
Washington state requires a licensed contractor (gas-fitter, with the L&I license to match) for any work on a gas line — including connecting a gas dryer's flexible gas connector to an existing gas shutoff. Unlicensed gas work carries criminal liability and voids homeowner insurance in the event of a leak or fire. We do not run gas, do not connect gas dryers, and tell you on the booking call when your request is gas instead of electric. We have a licensed Washington L&I gas-fitter we refer to, and we will gladly do the electric side of a mixed install (washer hookup, vent transition, dryer position) and let the licensed sub handle the gas connector.
Why are new stainless-braided hoses included by default?
Old rubber washer hoses are one of the top causes of homeowner water damage in the U.S. — they look fine, they hold pressure for years, and then they burst at three in the morning. The insurance industry tracks washer-hose failure as one of the most expensive single appliance-related claim categories (a burst hose can dump thousands of gallons into a home before anyone notices). We install new stainless-braided hoses on every washer install as a default, with PTFE tape on the male threads and a hand-tighten-plus-a-quarter-turn. The cost is in the price of the visit, not an upsell.
My dryer outlet is 3-prong instead of 4-prong — what does that mean?
The 4-prong dryer outlet (with a dedicated ground separate from the neutral) became the national code in 1996. Laundry rooms wired before then are often still 3-prong. New dryers ship with a 4-prong cord by default. The cleanest fix is a 3-prong pigtail conversion — the cord on the new dryer is field-replaceable (manufacturer-approved install method) and we swap the new 4-prong cord for a 3-prong cord that fits your existing outlet. The conversion takes about 10 minutes and costs $60. If you want the outlet itself upgraded to 4-prong, that routes to a licensed electrician under Washington L&I (it requires running a new ground wire from the panel) and we give you the name of our referred electrician.
What is the white accordion dryer vent and why do you replace it?
The white plastic accordion vent transition (the flexible duct between the back of the dryer and the wall-mounted vent opening) is a fire hazard and a code violation under modern requirements. The accordion ridges trap lint in heavy folds and the plastic can ignite from the high heat of a dryer cycle — the U.S. Fire Administration tracks roughly 2,900 home clothes-dryer fires per year, and lint accumulation is the leading cause. We replace any accordion transition with semi-rigid aluminum on every dryer install. The cost is in the base price, not an upsell.
What if my standpipe drain or laundry sink does not work?
We test the drain at the start of the install — a quick water test confirms free flow. If the standpipe is clogged or the laundry sink P-trap is failing, we will tell you. Clearing a clogged standpipe sometimes routes to a licensed plumber depending on how deep the clog is (a snake into the standpipe is within this trade; cutting into the wall to repair a broken drain is not). The diagnostic is part of the visit; the fix is on the estimate before we touch the new washer.
Can I get a stackable washer-dryer set installed?
Yes. Stackable sets need a two-person lift to put the dryer on top of the washer safely — the dryer is typically 100 to 130 pounds and goes up to chest height. We send a partner on every stackable install and use the manufacturer's stacking kit (bracketry that locks the dryer to the washer top). The lift adds $80 to the install and includes the cleaning of the stacking surface (no debris between the units), the kit install, and the level check on both units. Total visit time for a stackable set install runs 90 to 120 minutes.
Will Handis remove and haul away my old washer and dryer?
We disconnect the old units and move them to your garage, your curb, or wherever you have arranged pickup. We will set them at the curb for retailer haul-away or city pickup at no extra cost as part of the visit. Haul-away itself is not part of the install — we do not have a disposal vehicle and we are not a licensed appliance recycler. Most retailers offer haul-away with the new appliance delivery for $30 to $50, which is the cheapest path. The old units do contain refrigerant and metals that need proper recycling; Seattle Public Utilities offers appliance recycling pickup as a separate service.
How long does a washer and dryer hookup take?
A single washer or single electric dryer hookup on existing connections runs 30 to 45 minutes each, plus the 15-minute pre-install inspection. A washer-plus-electric-dryer set runs 75 to 100 minutes including the cleanup. A stackable set adds 20 to 30 minutes for the lift and the kit install. A 3-prong cord pigtail conversion adds 10 minutes per dryer. Worst case (washer plus dryer plus stack plus pigtail plus a new standpipe bracket) runs about 2 hours; a clean side-by-side set runs 90 minutes.
Is the work guaranteed?
Yes. 30-day workmanship guarantee on every washer and dryer install. If a hose we installed leaks, a vent transition slips, a drain hose dislodges from the standpipe, or any connection we made fails within 30 days due to our workmanship, we come back and fix it at no extra charge. The guarantee covers our work — it does not cover the new appliance's manufacturer warranty (motor, drum, heating element, control board, internal failures file with the manufacturer), and it does not cover pre-existing failures we flagged before the install (a cracked standpipe, a corroded hose bib, a clogged dryer vent past the transition we replace).
