How Much Does It Cost to Move Washer and Dryer Hookups in St. Louis, MO? [2026 Data]

The average cost to move washer and dryer hookups in St. Louis, MO, ranges from $808 to $1,712, with most homeowners spending $1,141. The main factors affecting St. Louis, MO, homeowners’ washer and dryer relocation costs are installing drain lines, electrical circuits, dryer vent installation, and local labor rates. This guide explains these factors to help you plan your project and budget accurately.

Washer and Dryer Hookup Relocation Cost Factors 

The cost to move washer and dryer hookups in St. Louis, MO, depends on several factors, such as drain line installation, potential electrical work, dryer vent installation, drywall repairs, and more. Let’s take a closer look at how your total breaks down.

Installing a Washing Machine Cut-Off Valve

A cut-off valve is necessary to stop the water supply to your washing machine. Your washing machine cut-off valve will likely cost $10 to $30 per line.

Building a Drain Line for the Washer

Relocating your washing machine gets trickier when plumbing costs are involved. And one major plumbing cost for relocating your washer and dryer is installing a drain line. Depending on how close it is to the existing plumbing, the price could range anywhere from $360 to $1,840.

If you try to tackle this work yourself and make a mistake, you’ll need to get a plumber in pronto. However, costs will be significantly higher. Emergency plumbing costs up to three times as much as standard plumbing.

Installing Electrical Outlets and Circuits

Your washer should run on a standard 120V outlet, while dryers need a high-powered outlet (240V) for proper power. The cost to install a new outlet is $220 to $550 if you need one for the washer, and $350 to $900 if you need a 240-volt plug for the dryer. The type of dryer plug on your unit will impact electrical costs. You also may need to cap an existing gas line, which costs $110 to $280 and takes approximately one to two hours.

Running a Gas Line (Gas Dryers Only)

If you’re installing a gas dryer, you’ll need to factor in the cost of running gas lines to your new laundry room. Prices vary, but the cost for a new gas line falls between $250 and $3,000 or more, based on how far you run the lines. Expect to pay $15 to $35 per linear foot to hire a pro who knows how to install gas lines.

Dryer Vent Installation

Dryers need a place to push out that hot air, so don’t forget to consider installing a dryer vent. A new dryer vent costs an average of $200 but can reach $600 depending on the vent's length. This works out to $12 to $20 per linear foot, or more if the vent needs to be routed through ceilings or other areas with difficult access.

Repairing Drywall

After you finish installing new hookups, you’ll likely have some minor drywall repair needs. Minor drywall repair can cost as little as $75, and your plumber or electrician may even include it in their labor cost. Sometimes, when moving your washer and dryer, you’ll uncover mold or water damage that needs further attention. In these cases, it’s best to call a mold remediation pro to test and suggest the best course of action.

Installing the New Machines

Once you’ve set up everything, you’ll have to think about installing the units themselves. If you’re buying new units, many will include installation in the cost. If that’s not the case, you can find an appliance installation service near you that understands washer and dryer parts and get it done for $150 to $450 per unit.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
