What to renovate first in an old house
Old house renovation? Yeah, it's a lot. You walk in and there's peeling wallpaper everywhere, floors that groan like they're alive, and a kitchen straight out of 1972. The trick? Knowing what to do first. Start with the stuff that keeps you safe—structural stuff, the bones—then worry about making it pretty later. This is the order that actually works, pulled from people who've been through the mess.
Why the order of renovation matters
Do it wrong and you're burning cash. Seriously. Imagine putting in brand-new kitchen cabinets, only to rip them out because the pipes behind the wall finally gave up. The rule? Outside in, bottom up, critical systems before you even think about paint colors.
What should you inspect before starting any renovation?
Don't touch a hammer yet. Get a home inspector—someone who knows old houses, not just new builds. They'll find the nasty stuff: foundation cracks, that ancient knob-and-tube wiring, lead paint, asbestos. It'll cost you maybe a few hundred bucks. Could save you thousands. Focus your worry on three things:
- Structural integrity: Foundation, roof trusses, load-bearing walls. A crack wider than a quarter-inch? Sagging floor? That's a problem.
- Water damage: Check for ceiling stains, that basement mustiness, soft spots in the floor. Mold and rot don't mess around.
- Electrical system: Old wiring is straight-up dangerous. If you see cloth-covered wires or screw-in fuses, you're looking at a full rewire.
What are the top priority renovations in an old house?
Here's the deal, based on what experts keep saying and what homeowners keep messing up:
| Priority Level |
Renovation Area |
Why It Matters |
| 1. Critical |
Roof and structural repairs |
Keeps water out and the house standing |
| 2. Critical |
Plumbing and drainage |
No mold, no foundation rot |
| 3. Critical |
Electrical system |
Less fire risk, can actually use modern stuff |
| 4. High |
HVAC and insulation |
Makes it livable, cuts energy bills |
| 5. Medium |
Windows and doors |
Better security, fewer drafts |
| 6. Low |
Cosmetic finishes (paint, flooring, cabinets) |
Wait until everything else is solid |
How do you handle plumbing and electrical in an old house?
These two are the biggest pain. Plumbing? Start with the main water line from the street—if it's lead or galvanized steel, replace it. Then swap all the visible pipes for PEX or copper. Electrical? Get a licensed electrician. You need a new panel, at least 200 amps. Rewire everything, every outlet, every switch. Honestly, don't try this yourself unless you really know what you're doing.

$5,000 - $20,000 |

What should you avoid renovating first?
First-timers always want to do the kitchen or bathroom. Don't. Seriously, resist. No new countertops or tile until the plumbing and electrical are sorted. And don't knock down walls without talking to a structural engineer first. Painting or wallpapering? Forget it until every leak is fixed and everything's dry.
Frequently asked questions about renovating an old house
Do I need permits for renovating an old house?
Yeah, for most big stuff—structural, electrical, plumbing, HVAC. Check with your local building department. Permits mean the work's up to code, and they'll protect you when you sell.
Can I renovate an old house myself?
Some things, sure. Painting, demo, flooring. But leave the structural, electrical, and plumbing to pros. Mess those up and it's dangerous and crazy expensive to fix.
How long does a full old house renovation take?
For 1,500 square feet, figure 6 to 12 months. Critical systems eat up 2-4 months, then the finishing touches. Expect delays—hidden rot or old wiring always shows up.
What is the most common mistake in old house renovation?
Starting the pretty stuff before the roof, plumbing, or electrical is done. Total waste of money and sanity. Systems first, style later.

Resumen breve
- Priorice los sistemas críticos primero: Comience con el techo, la estructura, la plomería y la electricidad antes de cualquier trabajo cosmético.
- No se salte la inspección: Una inspección profesional revela problemas ocultos como moho, cableado obsoleto y daños estructurales.
- Presupuesto para gastos imprevistos: Las casas antiguas suelen tener sorpresas. Reserve al menos un 20% adicional de su presupuesto para reparaciones inesperadas.
- Contrate profesionales para trabajos clave: La electricidad, la plomería y los cambios estructurales requieren licencia y seguro. Hágalo usted mismo solo en tareas superficiales.
