Washer & Dryer Installation in Los Angeles

Washer and dryer installation is the work of placing two heavy appliances into a laundry space, connecting them to water, drain, electrical, and (for gas dryers) gas, and verifying that the first cycle runs without leaks, vibration, or vent issues. A washer alone weighs 200 to 300 pounds out of the box, a dryer adds another 100 to 150 pounds, and the connections behind them are the part that fails most often when the work is rushed. A proper install covers positioning the units in the laundry niche, hooking up the hot and cold water supply lines on the washer, securing the drain hose into the standpipe or laundry sink, plugging the washer into a 120-volt outlet, plugging an electric dryer into a 240-volt outlet (or connecting a gas dryer to an existing gas valve), attaching a 4-inch flexible vent duct from the dryer to the outdoor exhaust, leveling both units so the washer does not walk during spin, and running a short test cycle to confirm everything holds.

Los Angeles laundry rooms come in three flavors that change how the work is scoped. DTLA condos and Koreatown apartments often have a stacked closet niche where a single full-size washer and dryer are stacked or a small all-in-one ventless unit lives in a hall closet. Older homes in Silver Lake, Pasadena, and Hollywood that were built before 1970 frequently have laundry hookups in the garage or basement, with outdated outlets, brittle vent hoses, and shut-off valves that have not turned in twenty years. Family homes in Sherman Oaks, Pasadena, and Encino tend to have a real laundry room with side-by-side full-size units, dedicated 240-volt service, a working gas line, and outdoor venting through the wall. Each of these settings has different risks: tight closets need a stacking kit and an extra set of hands, garages need attention to the older outlets and ground, and full laundry rooms usually just need a careful set-and-connect.

There is a clear line between handyman scope and plumber or electrician territory on this work. A vetted pro can swap an electric washer-dryer pair into existing hookups, install a stackable kit, add a pedestal, swap a same-fuel gas dryer onto an existing gas valve, replace a flexible vent hose, and add earthquake straps to a tall stacked unit. The pro does not run a new gas line, does not convert a fuel type from electric to gas (or vice versa), does not upgrade the dryer outlet from a 30-amp to a 50-amp circuit, and does not core a new vent path through a stucco exterior wall. Those jobs need a licensed plumber or electrician. A good pro will tell you that on the first call rather than after the unit is unboxed in your hallway.

You bought a new washer and dryer and the delivery driver dropped them in the garage without hooking anything up. This is the most common scenario in Los Angeles. Big-box appliance delivery in 2026 is curbside or threshold-only on most orders unless you paid for full installation, and even when you paid for it, gas-dryer hookups and stacking are usually excluded because the delivery crew is not licensed for them. A vetted handyman can finish the job the same day and have you running a load before dinner.

You moved into an apartment or condo that already has hookups in a closet, but the previous tenant took their units. You need a pro who can position the new washer and dryer in a tight space without scratching the floor or wall, connect everything cleanly, and confirm the closet door still closes after install. Stacked closet niches in Koreatown, DTLA, and Mid-Wilshire condos are especially tight — measuring before delivery is the difference between a smooth install and a return.

You want to convert a side-by-side pair into a stacked pair to free up floor space. This requires the manufacturer-specific stacking kit (LG kits do not fit Samsung units, Whirlpool kits do not fit Maytag, and so on), proper alignment between the bottom of the dryer and the top of the washer, and earthquake straps anchored into a stud or masonry. A pro brings the kit, the helper for the lift, and the stud finder for the strap.

Your current dryer is an old electric model with a 3-prong NEMA 10 cord and you just bought a new dryer that comes with a 4-prong NEMA 14 cord. National code has required 4-prong outlets on new construction since 1996, but homes built before that still have the older 3-prong receptacle. The right fix is to replace the receptacle with a modern 4-prong (an electrician's task on the circuit) and swap the dryer cord to match. A handyman can swap the dryer cord; the receptacle change at the panel is electrician scope on most jobs.

You want to add a pedestal under the washer or dryer to raise it 13 inches for ergonomics. This is a cosmetic and back-friendly upgrade, especially in Sherman Oaks, Encino, and Pasadena family homes where the laundry room is used daily. The pedestal install adds 30 to 60 minutes to the job because the unit has to be lifted onto the pedestal, anchored, and re-leveled, but it is a clean handyman scope on existing electric hookups.

Confirm the pro is honest about scope before the visit. A right-fit pro will ask whether the dryer is gas or electric, whether the existing outlet is 3-prong or 4-prong, whether the gas valve is already in place, and what the vent run looks like. A pro who answers yes to everything without asking the questions is either inexperienced or willing to do work that should be referred. Same-fuel swap on existing hookups is straightforward; new gas line, fuel conversion, or panel circuit work is not.

Look at the verification badges. Every Shatun Brothers washer-dryer install pro has cleared Persona ID + selfie liveness — that's required to list. The badge you most want to look for here is Insurance Verified: leaks under a washer are the most common late-breaking claim on this kind of work, and a pro with current general liability coverage on file gives you cleaner recourse if something fails. License Verified is a separate badge for pros who hold a CSLB license — useful information for larger jobs, but not required for handyman-scope installs.

Match the pro to your space type. A pro who has done thirty stackable closet installs in Koreatown apartments is the right call for a tight DTLA loft. A pro who has done forty side-by-side installs in Sherman Oaks family homes is the right call for a roomy laundry room with a gas dryer hookup. We show the last ten reviews on every pro profile so you can read what kind of jobs they finish well, not just the average rating.

Ask whether the pro brings the stacking kit, vent hose, and earthquake straps, or expects you to. The kit is unit-specific and runs $60 to $130 from the manufacturer. A foil flexible vent hose is $15 from the hardware store. Earthquake straps are $20 to $30 each. A pro who shows up with everything saves you a trip; a pro who asks you to buy them ahead of time is normal too — just confirm in writing which side is doing what.

Get the leveling expectation in writing. A washer that is even half a degree off level on a slope-drain laundry floor will walk during spin and beat itself against the dryer. The right answer is a digital level on the top of the washer, adjusting all four legs (not just two), and re-checking once the unit is loaded for the first cycle. If the pro skips the digital level and eyeballs it, that is a flag.

Confirm the test cycle is part of the quote. The job is not done when everything is connected — it is done when a real cycle has run with water and the pro has confirmed there are no leaks at the supply hose connections, no leaks at the drain, no rocking on the legs, and no kink in the vent. Five minutes of testing before the pro packs up is the difference between a clean install and a Saturday morning callback.

Same-fuel replacement on existing hookups is realistic DIY for a confident homeowner. If the old dryer was electric and the new one is electric, the connections are hose-to-faucet for water, hose-to-standpipe for drain, four-prong cord into the existing outlet for the dryer, and a flexible vent hose to the outdoor duct. The lift is the hard part — both units are heavy and awkward, especially in a closet niche, so a helper is the difference between a clean install and a hernia. Plan two to three hours, follow the manufacturer manual exactly, and remember to remove the shipping bolts before the first cycle. Forgetting those bolts is one of the most expensive DIY mistakes on this job — the washer drum will destroy itself in the first spin.

Stacking and pedestals are also reasonable DIY if you have the right kit and a helper. The lift is heavier and the alignment matters because the manufacturer-specific stacking kit only forgives so much. A digital level on the top of the unit during the final tighten is mandatory, not optional. Earthquake straps for tall stacked units are simple enough to install once you have located a stud or anchor — but if the wall is metal stud or lath-and-plaster, the anchor work gets harder fast and the strap is the kind of thing you do not want to redo after a tremor.

Hire a pro any time gas, fuel conversion, panel work, or new venting is involved. New gas line installation is licensed plumber territory — it requires a permit in Los Angeles, a pressure test, and an inspection. Converting an electric dryer hookup to a gas dryer hookup, or vice versa, crosses both plumbing and electrical scope. Upgrading the dryer outlet from a 30-amp 3-prong to a 30-amp 4-prong at the panel is electrician scope. Coring a new vent path through a stucco exterior wall is a finish-and-flashing job that gets ugly when done wrong. The cost difference between a $250 pro install and a botched DIY that floods a closet, voids a manufacturer warranty, or damages a unit during a stack lift is usually 10x.

Forgetting to remove the shipping bolts before the first cycle. New washers ship with three or four large bolts through the back panel that lock the inner drum to the cabinet for transit. If those bolts are still in place when the first cycle runs, the drum cannot float and the entire unit destroys itself within a few minutes — burned-out motor, cracked tub, sometimes a leak through the floor. The bolts come out with a wrench in two minutes, and the holes get covered with the included plastic plugs. This is the single most expensive DIY mistake on washer installs.

Skipping the level. A washer that is off level by even a small amount will walk during spin, beating against the dryer, the wall, or the floor. Over months, the walking shears the drain hose, loosens the supply lines, and breaks the standpipe connection. The right way is a digital level on top of the washer, adjusting all four legs until both axes read zero, and rechecking after the first loaded cycle. Eyeballing it is not enough on a sloped laundry-room floor, which most older LA garages have for drainage.

Plugging a new 4-prong dryer cord into an old 3-prong outlet, or the other way around. National code has required 4-prong dryer receptacles on new construction since 1996, but homes built before that still have the older 3-prong NEMA 10 receptacle. New dryers come with a 4-prong NEMA 14 cord. The right fix is one of two things: have an electrician swap the receptacle to a modern 4-prong on its own circuit (the correct long-term answer), or swap the dryer cord to match the existing outlet (legal in most cases, but not preferred). Do not file down the prongs to make them fit — that is a shock and fire hazard.

Kinking the vent hose. The 4-inch flexible aluminum vent hose between the dryer and the wall duct should run as straight as possible, with smooth bends, and never compressed flat. A kinked or crushed hose traps lint, drops dryer efficiency, and is one of the leading causes of residential dryer fires nationally. The vent run should be no longer than 25 feet total, with deductions for each elbow (5 feet per 90-degree elbow per most manufacturers). If the run cannot meet that, the vent path needs to be shortened or rerouted — that is a real install decision, not a thing to ignore.

Skipping earthquake straps on tall stacked units. Los Angeles is earthquake country, and a stacked washer-dryer is a tall, top-heavy assembly with a high center of gravity once the dryer is loaded with clothes. A moderate shake without straps tips the dryer off the washer; a hard shake puts it through the laundry-room wall. Two straps anchored into a stud, run around the back of the dryer at the top, take ten minutes and $40 to $80 in materials. They are not optional on stacked installs in any LA neighborhood, and a good pro will refuse to leave a stack untethered.
