Remodeling an old house typically costs $100-$300 per square foot, with extensive restorations reaching $500 or more per square foot. The total depends on the home’s size, condition, finish choices, location, and whether outdated wiring, plumbing, or structural problems need correction.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house remodel | $75,000 | $225,000 | $600,000+ | About 1,500 sq ft; scope ranges from basic updates to major restoration |
| Cost per square foot | $50-$100 | $100-$300 | $300-$500+ | Higher rates reflect extensive repairs and premium finishes |
| Kitchen remodel | $15,000 | $35,000 | $80,000+ | Cabinet, appliance, and layout changes affect price |
| Bathroom remodel | $8,000 | $20,000 | $45,000+ | Assumes one bathroom; plumbing relocation adds expense |
What an old-house remodel costs by project size
For a 1,500-square-foot home, a limited refresh may cost $75,000-$150,000, while a broad interior renovation often runs $150,000-$450,000. Restoring a severely neglected house or matching historic finishes can push the bill above $750,000, especially in high-cost cities.
A practical planning range is $100-$300 per square foot for a substantial remodel. The lower end generally covers surface upgrades and selective repairs; the upper end may include kitchens, bathrooms, mechanical systems, and new finishes throughout. Assumptions: U.S. contractor pricing, ordinary access, midrange materials, and no major addition.
How framing, systems, and finishes appear in the quote
Contractor estimates typically separate demolition, repair, installation, and finish work. Old homes can require more investigative work than newer properties because concealed damage may not be visible until walls or floors are opened.
| Work item | Typical price | Pricing basis | What changes the quote |
|---|---|---|---|
| Demolition and disposal | $3,000-$15,000 | $2-$8 per sq ft | Hazardous material handling and access |
| Structural and framing repairs | $5,000-$40,000 | $50-$150 per labor hour | Rot, settlement, damaged joists |
| Electrical and plumbing | $15,000-$50,000 | $8-$20 per sq ft | Rewiring, repiping, fixture locations |
| Insulation, drywall, and finishes | $20,000-$80,000 | $15-$60 per sq ft | Finish grade and wall condition |
| Design, permits, and inspections | $3,000-$25,000 | Fixed fee or project percentage | Local review and project complexity |
Labor and concealed repairs often account for the largest uncertainty. A remodeling contractor may also include project management, insurance, overhead, and a contingency allowance in the estimate; ask whether each appears as a separate line item.
Which age-related repairs push the price upward?
Condition matters more than the home’s age alone. A house with a sound foundation and updated utilities may cost less to remodel than a newer property with water damage, poor access, or an altered layout. Request a written scope that distinguishes known work from allowances for hidden conditions.
Set aside 15%-25% of the construction budget for discoveries behind walls. For example, replacing a 100-amp electrical panel with a 200-amp service can add roughly $2,000-$5,000; a full-house rewire may cost $8,000-$25,000. Replacing galvanized supply lines can add $4,000-$15,000, depending on house size and wall access.
Lead paint in homes built before 1978 and asbestos-containing materials in older insulation, flooring, or pipe wrap may require testing and controlled removal. Testing can cost $300-$1,000; remediation ranges from several hundred dollars to $10,000 or more depending on material and extent. Labor estimate formula:
Ways to control the old-house renovation budget
Keeping the existing footprint and plumbing locations can avoid substantial framing and utility work. A kitchen refresh that retains service locations may cost $15,000-$35,000, compared with $40,000-$80,000 or more when walls, cabinets, and plumbing are extensively changed.
Choose repairs and finish upgrades according to condition, not appearance alone. Refinish sound wood floors rather than replacing them, preserve usable cabinets, and specify standard-size windows and doors where appropriate. For historic features, price restoration against replacement before deciding; custom millwork can cost several times more than standard trim.
Compare at least three detailed bids using the same drawings, finish allowances, and exclusions. Check whether demolition, cleanup, permit fees, and temporary protection are included. Avoid choosing a bid solely because its initial total is lowest: a very small contingency or vague allowances can lead to costly change orders.
Regional labor rates change the same 1,500-square-foot project
Construction labor and permitting can make otherwise similar projects vary widely. In lower-cost rural and Midwestern markets, a substantial remodel may fall near $100-$225 per square foot. Major coastal cities and high-demand metro areas can run 20%-50% above that range, particularly for skilled trades and older-home specialists.
Location can shift a whole-house quote by tens of thousands of dollars. A $225,000 project at typical pricing might reach roughly $270,000-$340,000 in a high-cost market, before unusual structural repairs. Rural projects are not always cheaper if materials, specialty trades, or disposal must travel long distances.
How long crews work and what their time costs
A selective room-by-room renovation may take 2-4 months; a full interior remodel commonly takes 6-12 months, excluding extended design and permit reviews. Contractors may charge project labor within a fixed bid, while specialty trades often bill at $75-$150 per hour. Historic restoration specialists may charge $100-$200 per hour in expensive markets.
Schedule and labor availability affect both duration and total expense. A larger crew can shorten active work but does not necessarily reduce the number of trade hours. Living in the home during construction may also require phased work, added protection, and repeated mobilization, potentially increasing labor charges.
Three old-house remodel budgets with different scopes
A 900-square-foot cottage with fresh paint, refinished floors, and limited electrical repairs might cost $55,000-$100,000. At $60-$110 per square foot, the work could involve 500-800 labor hours; it assumes the kitchen and bathroom remain largely intact.
Scope determines whether a quote is a refresh, a full renovation, or a restoration. A 1,500-square-foot home with a remodeled kitchen and two bathrooms, updated wiring and plumbing, and midrange finishes might total $225,000-$375,000, or $150-$250 per square foot. A 2,000-square-foot house needing structural repairs, new systems, custom windows, and premium finishes could reach $500,000-$900,000, or $250-$450 per square foot.
These examples exclude major additions and land costs. Before signing, confirm that the estimate states the square footage, material allowances, labor scope, schedule, payment milestones, and procedures for approving changes.
