A microwave installation in St. Louis, MO, runs $174 on average, and ranges from $129 to $250. Your total price depends on the microwave type, required cabinet modifications, and local labor rates. Before starting this kitchen upgrade, understanding the cost helps you plan a project that fits your home and budget.

Microwave Installation Cost Factors

When planning for a kitchen upgrade in St. Louis, MO, hiring a local appliance installer ensures your new unit is mounted safely and securely. The final price of your project depends on several variables, including the type of appliance you choose, the complexity of the mounting process, and any necessary electrical upgrades.

New Microwave

The style and features of the unit you select serve as the foundation for your total expenses. High-end smart models or combination ovens require a larger upfront investment than standard countertop versions. In St. Louis, MO, homeowners choose from a variety of styles to fit their culinary needs. For instance, a basic countertop model ranges from $100 to $555 per unit, while a premium combo oven runs from $2,480 to $4,950 per unit.

Microwave TypeLocal Average Installation CostNational Average Installation Cost
Countertop$100–$555$100–$580
Over-the-range$240–$1,150$250–$1,200
Built-in$480–$2,380$500–$2,500
Drawer$1,200–$2,320$1,260–$2,430
Combo oven$2,480–$4,950$2,600–$5,200

Microwave Mount

The location and method used to secure your appliance directly influence the complexity of the job. Mounting a unit under a cabinet or over a range requires specific hardware and structural support to ensure it stays safely in place. If you are updating your kitchen in St. Louis, MO, you will also need to consider your overall kitchen remodeling costs, which include the price of specialized mounting kits. Depending on the setup, basic mounting brackets and hardware add flat one-time material expenses to your bill.

Labor

Hiring a professional ensures the job is done safely, and the time required to complete the work dictates your labor fees. Complex installations that involve custom carpentry or wiring take longer and increase the final bill. On average, homeowners in St. Louis, MO, pay a total project cost of $174 per project for this service. Most standard replacements fall between $129 and $250 per project, depending on the hourly rate of the appliance installer. If your project requires additional tradespeople, you must factor in appliance repair services or fees for specialized contractors.

Electrical Wiring

Your home must have the correct voltage and a dedicated circuit to safely power a modern cooking appliance. Older homes in St. Louis, MO, often lack adequate wiring, meaning you will need to hire an electrician to bring the system up to code. The region's stormy and extreme weather leads to power surges, making a properly grounded and updated electrical system essential for protecting your investment. Upgrading an old outlet or installing a new one adds to your total expenses, much like how an electrical panel upgrade cost impacts a larger renovation.

Modifying or Updating Cabinets

Built-in and drawer models require custom carpentry to ensure a seamless fit within your existing kitchen layout. Altering the dimensions of your woodwork adds specialized labor and material fees to the project. In St. Louis, MO, the humid climate causes older wood to swell, making precise cabinet repair or modification even more critical during installation. Adjusting a single cabinet to accommodate your new appliance increases your budget, and extensive changes are priced per linear foot.

Ventilation

Over-the-range units require proper ductwork to channel smoke, steam, and cooking odors safely out of your home, working alongside your HVAC system. Installing new exhaust routing is labor-intensive and requires cutting through walls or ceilings, which drives up the price. For residents of St. Louis, MO, ensuring a tight seal on exterior wall vents is important to keep out the extreme winter cold and summer humidity. If you do not have existing ductwork, adding a direct vent to the outdoors significantly increases your overall expenses, similar to a new range hood installation.

Removal and Disposal of an Old Microwave

Getting rid of your broken or outdated appliance involves hauling it away and paying standard recycling or landfill fees. Many professionals include this service in their initial quote, but others charge a separate flat one-time fee for the convenience. In St. Louis, MO, local disposal regulations dictate how electronic waste must be handled, which affects the final price. If disposal is not included, you will pay an additional fee to safely remove the old unit from your property.

Appliance Installer Pro Costs

Hiring a professional to handle your microwave setup in St. Louis, MO, ensures safe electrical connections and secure mounting. On average, homeowners pay $174 per project for this service. Most standard replacements fall between $129 and $250 per project, depending on the job's complexity and the appliance installer's hourly rate. When budgeting for your kitchen upgrade in St. Louis, MO, remember to account for the 9.68% local sales tax rate on materials and mounting hardware.

Why You Should Hire an Appliance Installer

Bringing in an appliance installer in St. Louis, MO maximizes your time, guarantees a secure setup, and provides excellent long-term value for your kitchen upgrade.

  • Professionals possess specialized stud-finding equipment to properly anchor heavy over-the-range units.

  • Experts understand local building codes in St. Louis, MO, ensuring precise cabinet clearances.
