How Much Does It Cost to Renovate an Old House?
Renovating an old house can be a rewarding yet challenging endeavor. Whether you’re looking to restore a historic home to its former glory or simply make an aging house more livable, understanding the costs involved is crucial for budgeting and planning. The cost of renovating an old home varies widely depending on the condition of the property, the scope of work, the materials used, and whether you’re hiring professionals or taking a DIY approach. In this comprehensive guide, we’ll break down the different costs associated with old home renovations, factors that influence these costs, and ways to save money while preserving the character of your home.
Factors That Influence the Cost of Renovating an Old Home

1. Age and Condition of the Home
Older homes often come with hidden issues such as outdated electrical systems, deteriorating plumbing, or structural concerns. The older the home, the more likely it is that significant repairs will be needed before any cosmetic updates can take place.
Minor Repairs (smaller in scope and localized; plaster repairs, trim repairs, siding repairs): $5,000-$30,000
Moderate renovations (multiple trades; could involve some structural repairs like rotted sills or studs; some lifting/supporting required; kitchen and bath renovations): $30,000–$150,000
Major renovations (large structural repairs, full gut and rebuild, additions): $150,000–$400,000+
2. Size of the House
Larger homes naturally require more materials and labor, increasing overall costs. The number of rooms, bathrooms, and levels in the home will influence the budget significantly. Renovation costs typically range from $90-$200 per square foot, depending on the extent of the updates.
3. Structural Repairs
Structural issues, such as foundation problems, rotting wood, or a failing roof, can drastically increase costs. Here are some common structural repairs and their estimated costs:
Foundation repair: $40,000–$150,000
Roof replacement: $15,000–$35,000
Replacing load-bearing walls: $15,000–$35,000
Fixing wood rot: $2000–$10,000 (depending on severity)
4. Cosmetic Updates
Once the major repairs are addressed, aesthetic renovations can be completed to restore the charm of an old house.
Refinishing hardwood floors: $5,000–$15,000
Painting interior walls: $2,000–$7,000
Kitchen renovation: $35,000–$80,000
Bathroom remodel: $25,000–$70,000
Restoring original windows: $1200–$5,500 per window
Additional Cost Considerations
Historic Homes and Preservation Costs
If your home is considered historic, renovations may be subject to additional guidelines and restrictions. Using historically appropriate materials and methods can increase costs.
Preservation architect consultation: $15,000–$65,000
Custom woodwork and millwork (requires initial setup of machines/profiles: $5,000+
Matching historical materials: 20–50% higher than modern materials
Permit and Inspection Fees
Depending on your location and the extent of renovations, you may need permits for electrical, plumbing, or structural work.
Building permits: $500–$5,000
Historic district approvals: Variable, depending on local regulations
Home inspections: $500–$2,000
Unforeseen Issues and Contingency Budgeting
Old homes often hide surprises behind walls and under floors. It’s wise to set aside 10–20% of your total budget for unexpected costs.
How to Save Money on Old Home Renovations
1. Prioritize Repairs
Start with essential structural and safety repairs before moving on to cosmetic improvements. A well-structured renovation plan helps prevent overspending. Consult with your contractor on this. A serious problem like a settling foundation or a rotted sill that gets overlooked can come back to bite you after you’ve already spent your money on less important renovations.
2. Reuse and Restore
Many old homes contain valuable materials such as hardwood flooring, original doors, and antique fixtures. Restoring rather than replacing can save money while preserving character.
3. DIY Where Possible
Certain tasks like painting, minor demolition, or refinishing cabinets can be done yourself to reduce labor costs.
4. Phase Out the Work
If budget constraints are tight, consider renovating in stages rather than tackling everything at once.
Final Thoughts
Renovating an old home is a complex but rewarding process. While costs can vary widely, careful initial planning can help you mitigate cost overruns. Whether you’re restoring a historic property or making an older home more functional, understanding the costs involved ensures that your renovation remains on track without unnecessary financial surprises.
