How to Remodel a House: Step-by-Step Guide

Most failed remodels did not fail at design. They failed at sequence. How to remodel a house well comes down to running 14 phases in the correct order, because doing rough plumbing after drywall is more expensive than tearing out a whole room and starting over. This guide is the practical sequence — the order a general contractor would walk you through if you were standing in the empty kitchen on day one — with realistic timelines for a 1,800-square-foot home and the points where homeowners most often derail the schedule.

Phase 1: Plans and Scope (4 to 8 weeks)

Get drawings before you swing a hammer. For a kitchen-and-baths refresh, a kitchen designer or design-build contractor can produce working drawings in two to four weeks for $1,500 to $5,000. For structural changes — walls coming out, additions, second-story bumps — you need a licensed architect. Architectural fees run 8 to 15 percent of construction cost, with $4,000 to $12,000 typical for a substantial remodel.

Use this phase to lock the scope. Every change order after demo starts costs roughly 30 percent more than the same item priced into the original bid.

Phase 2: Permits (2 to 8 weeks)

Most US municipalities require permits for any work that touches electrical, plumbing, gas, structural, or the building envelope. Cosmetic work usually does not. Permit fees scale with project value, typically 1 to 2 percent of construction cost. Expect 2 to 4 weeks in most jurisdictions, longer in coastal California, the Northeast, and historic districts.

Skip the permit and you will have problems at resale, with insurance after a claim, and with future contractors who refuse to touch unpermitted work.

Phase 3: Demolition (1 to 2 weeks)

Demo is faster and dirtier than homeowners expect. Plan for one 20-yard dumpster per 600 square feet of gut, at $400 to $700 per dumpster. Containment matters more than speed: zip walls with 6-mil plastic, negative-pressure fans, and a single point of entry/exit keep dust from migrating to the rest of the house.

Pull cabinets and fixtures intentionally. A working stove, vanity, or set of cabinets can be sold or donated and offset $300 to $1,500 in budget.

Phase 4: Structural and Framing (1 to 3 weeks)

Any walls coming out get headers and posts. Any walls going in get framed at this stage. Window and door rough openings, beam pockets, attic access, and chase walls for plumbing and HVAC all happen here. The work moves fast — most kitchen-bath remodels are framed in three to six days — but skipping inspection between framing and the next phase is a hard mistake to recover from. Schedule your framing inspection while the walls are still empty.

Phase 5: Rough Mechanicals (1 to 2 weeks)

HVAC, plumbing, and electrical roughs run in roughly that order, sometimes overlapping. HVAC ducts and refrigerant lines go first because they are the largest. Plumbing supply and drain lines come next. Electrical, low-voltage, and structured wiring last. This phase is where good drawings pay off — every fixture location, every outlet, every switch, every recessed can needs to be marked on the studs.

Walk the house with the electrician once everything is in. Stand at every counter, every bedside, every TV location, and verify the box is where you actually want the device. After drywall the cost to move an outlet is 8x what it was before.

Phase 6: Insulation and Inspection (3 to 5 days)

Insulate the exterior walls (R-19 to R-23 in 2×6 walls, R-13 to R-15 in 2×4 walls), the attic floor (R-49 to R-60 in most climate zones), and any rim joists. Get the rough inspection signed off before insulation goes in if your jurisdiction requires it; most do.

Phase 7: Drywall and Plaster (1 to 2 weeks)

Hanging is one to two days for a 200-square-foot kitchen. Taping, mudding, and sanding takes another four to seven days because of dry time between coats. Plan on three coats of compound, sanded smooth, primed, before any cabinet or trim work happens.

Phase 8: Trim, Doors, Cabinets (1 to 3 weeks)

Order doors and trim 6 to 10 weeks ahead of this phase. Order cabinets 8 to 14 weeks ahead. Custom cabinets can be 20 weeks. Hang interior doors and casing first, then base molding, then cabinets, then crown. Cabinets going in before base allows the kicks to die into the floor cleanly.

Counters get templated only after cabinets are installed and level. Stone fab takes another 7 to 14 days, which is the longest single non-overlap-able pause in the schedule.

Phase 9: Tile, Flooring, Paint (1 to 2 weeks)

Tile work — backsplashes, shower walls, tub surrounds — typically happens before or alongside paint. Wood floors go in before final paint if site-finished, after final paint if pre-finished. Sequence flooring with the painter so dust does not contaminate finish.

Three coats of paint is the professional standard: primer, finish coat, finish coat. Latex eggshell on walls, semi-gloss on trim, ceiling-grade flat overhead.

Phase 10: Plumbing and Electrical Trim (3 to 5 days)

Faucets, toilets, sinks, drain assemblies, and disposal go in. Outlets, switches, light fixtures, and devices get installed and tested. This is where punch list items first surface — a misaligned switch box, a wobbly faucet, a recessed can pointed three degrees off.

Phase 11: Appliances, Finals, Punch (1 to 2 weeks)

Appliances arrive and connect. Final HVAC inspection, final plumbing, final electrical, final building all need to be scheduled in sequence with the inspector. The punch list — the small items everyone agrees need to be touched up before the contractor signs off — usually takes another five to ten working days.

Realistic Total Timeline and Cost

A whole-house remodel of an 1,800-square-foot home runs 16 to 26 weeks once demo starts. Total cost lands at $150,000 to $400,000 for a moderate remodel and $400,000 to $800,000 for a high-end gut, depending on metro and finish level. Add 15 percent contingency to whatever number your contractor gives you.

The Most Common Sequencing Mistakes

Ordering cabinets before drawings are final. Hanging drywall before the rough inspection. Painting before tile. Installing flooring before the cabinets are dropped. Each one of those errors costs $2,000 to $10,000 to undo. Slow down at the planning stage and the build phase moves faster than you think.
