A kitchen construction company handles the parts of a kitchen project that happen behind the walls and under the floor, not just the cabinets and countertops you see at the end. That includes demolition, structural changes, plumbing, electrical, ventilation, drywall, flooring and the permits and inspections that tie it all together. If your plan goes beyond swapping doors and counters, understanding that hidden work explains why some projects need a builder rather than a showroom, and what you are paying for in a full renovation.
Cosmetic Refresh or Construction Project?
Not every kitchen needs a builder. A useful first question: can your goals be met without opening walls or moving utilities?
- Cosmetic refresh: paint, new hardware, cabinet refacing, a new countertop on existing cabinets, a backsplash and light fixtures in existing boxes. Little or no permitting, short disruption.
- Replacement in place: new cabinets and counters in the same layout, with plumbing and electrical reconnected where they already are. Some permits, moderate disruption.
- Full renovation: layout changes, walls removed or added, utilities relocated, new circuits, new flooring and lighting throughout. Permits, inspections and a coordinated team of trades.
If your cabinet boxes are sound and you like the layout, refacing may stretch your budget further; our article on kitchen cabinet refacing explains when it works. The rest of this page focuses on the third category, where construction skills matter most.
What a Kitchen Construction Company Does Behind the Walls
A full renovation is a sequence of trades, each depending on the last. The builder's job is to schedule them in the right order, make sure each is inspected, and keep the site safe and protected in between.

Demolition and Structural Work
Demolition removes cabinets, counters, flooring and sometimes drywall down to the studs. It is also the moment of truth, because water damage, termite activity, outdated wiring or previous unpermitted work often appear only now. Opening the kitchen to the living area usually means removing a wall, and if that wall carries load from the roof or a floor above, it needs an engineered beam and properly sized posts and connections. In Florida, those connections are also part of how the house resists wind uplift, so structural changes are drawn and permitted rather than improvised.
Before demolition starts, the builder should shut off and cap water, gas and electrical lines serving the kitchen, protect adjacent floors and doorways, and set up a dumpster or haul-off plan. Homes built before the late 1970s may also contain materials such as older floor tile adhesives or textured ceilings that should be tested before they are disturbed. Taking these precautions at the start keeps the rest of the house clean and avoids surprises halfway through the job, when changing course is far more costly.
Plumbing and Gas Rough-In
Moving a sink to an island or a new wall means new drain lines with correct slope and venting, plus new supply lines. On a slab foundation, that typically involves cutting and trenching concrete. Venting an island sink takes particular care because there is no wall to run a vent up through. Gas lines for a range or cooktop must be sized and installed by a properly licensed professional and pressure tested. A dishwasher, refrigerator with ice maker and pot filler each add their own supply and drain requirements.
Shutoff valves deserve attention while the walls are open. Replacing old supply stops under the sink, adding an accessible shutoff for the refrigerator line and choosing quality braided connectors are inexpensive at this stage and prevent the slow leaks that ruin cabinet floors later.
Electrical Work and Lighting
Modern kitchens demand far more electrical capacity than older ones were built for. Code requires dedicated circuits for many appliances, ground-fault protection for countertop receptacles, and specific spacing so no point along the counter is too far from an outlet. Islands and peninsulas need receptacles too. Many renovations also reveal that the main panel lacks space or capacity for new circuits, which can lead to a panel upgrade.
Lighting deserves its own plan: recessed or surface ceiling lights for general illumination, under-cabinet lights for the counters, pendants over the island, and possibly in-cabinet or toe kick lighting. All of it is wired during rough-in, so decisions must be made before drywall.
Ventilation and the Range Hood
A range hood is only effective if it is ducted outdoors with the right size duct and as few bends as possible. Recirculating hoods filter grease but return heat and moisture to the room, which matters in a humid climate. High-capacity hoods can require make-up air provisions under the mechanical code. Duct routes through cabinets, ceilings or exterior walls should be planned before framing is closed, and exterior penetrations must be flashed and sealed against wind-driven rain.
Inspections, Insulation and Drywall
Before walls are closed, the building department inspects framing, plumbing, gas and electrical rough-in. Only after those pass does insulation go in where needed, followed by drywall, taping and finishing. Moisture-resistant board is often used near the sink. Skipping or rushing inspections can lead to tearing out finished drywall later, so a reliable builder schedules them as part of the plan rather than treating them as an obstacle.
Flooring, Cabinets, Counters and Finish
With walls finished and primed, work moves to the visible layers. Depending on the flooring type, it may be installed before or after cabinets. Cabinets are set level and secured, countertops are templated and installed, then the backsplash, sink, faucet, appliances, light fixtures and trim follow. Final electrical and plumbing inspections close the permit, and a punch list catches small adjustments before the project is complete.

Frequently Asked Questions
Clues include walls that run perpendicular to ceiling joists, walls directly beneath another wall on a floor above, and walls near the center of the house. However, only an inspection of the framing, and often an engineer's review, can confirm it. Never remove a wall based on a guess, because the consequences can include sagging ceilings and structural failure.
It typically adds cost because new drain and vent lines must be run to the island, often requiring the concrete slab to be cut and patched in Florida homes. Venting an island sink also requires special techniques allowed by code. The work is very doable, but it should be priced and planned before you commit to the layout.
Not always. It depends on your panel's capacity and how many open spaces it has for new circuits. Adding an induction range, double oven or several dedicated appliance circuits may exceed what an older panel can support. An electrician can evaluate the panel during the planning visit and tell you whether an upgrade is needed.
Ground-fault circuit interrupter protection quickly shuts off power if current leaks to ground, such as through water or a person. Kitchens combine water and electricity, so code requires GFCI protection for countertop receptacles. Protection can come from GFCI outlets or GFCI breakers in the panel, depending on the design.
Venting outside is strongly preferred because it removes heat, grease, odors and moisture from the house. Recirculating hoods filter grease but return warm, humid air to the kitchen. In Florida's climate, getting moisture out of the house is especially helpful. Duct size and route should match the hood's requirements for it to work properly.
Common discoveries include water damage from old leaks under the sink or behind the dishwasher, termite damage, corroded or outdated plumbing, undersized or unsafe wiring, and missing insulation. Older homes may also have previous work that was never permitted. A good contractor documents what is found, explains options and prices any corrections before proceeding.
Typical measures include plastic sheeting or zip-wall barriers around the work area, covered HVAC returns, protected flooring along walking paths, and daily cleanup. Some contractors use air scrubbers during dusty phases such as drywall sanding. Discuss dust control before work begins, especially if anyone in the household has allergies or respiratory concerns.
No. Drywall should be hung, taped, finished and primed before cabinets are installed. Doing it the other way around leaves unfinished wall behind and around cabinets and makes it harder to get clean lines. The exception is temporary positioning to check fit, which some installers do before final finishing in tricky spaces.
Most people stay home, using a temporary kitchen set up in another room. Moving out may make sense if other areas are being renovated at the same time, if utilities will be off for extended periods, or if anyone is sensitive to dust and noise. Your contractor can tell you which days will be most disruptive.
When a powerful hood exhausts a lot of air, the house needs replacement air to avoid negative pressure, which can affect other appliances and doors. Mechanical code may require a make-up air system when hood capacity exceeds a certain level. Your contractor will check the requirement based on the hood you choose and how the home is built.
Rough-in duration depends on how much plumbing, gas and electrical work is changing and how quickly inspections can be scheduled. A replacement in the same layout may need only a short rough-in, while a reconfigured kitchen with slab work, new circuits and ductwork takes longer. Inspections must pass before drywall can begin.
Each trade builds on the previous one. Plumbing and electrical must be in the walls before insulation and drywall, cabinets must be level before countertops are templated, and countertops must be set before the backsplash and sink. Doing things out of sequence leads to rework, damaged finishes and missed inspections, which cost time and money.
