Renovating an existing home is harder than fitting out a new one, and it is priced as though it were easier. The difference is that a new flat is a known quantity; an older house is a set of assumptions waiting to be tested.
This is what actually happens when you renovate a home in Delhi NCR — what it costs, what goes wrong, and how to keep control of it.
First: decide what kind of renovation this is
Three broad levels, and the cost gap between them is enormous.
Cosmetic refresh. Paint, some new joinery, lighting changes, furniture. No civil work, no services touched. The least expensive of the three by a wide margin. Six to ten weeks. Sensible for a home that works but looks tired.
Partial renovation. Kitchen and bathrooms redone, flooring replaced, new joinery throughout, electrical upgraded. Layout largely unchanged. Three to five months.
Full strip-back. Everything out to the shell. New layout, new services, new everything — several times the cost of a cosmetic refresh. Six to twelve months.
The mistake people make is budgeting for a partial renovation and then asking for changes that only a strip-back can deliver. Moving a bathroom is not a partial renovation. Neither is opening a kitchen into a living room.
What you will find behind the walls
In any Delhi home older than about twenty years, assume you will find at least two of these:
Wiring that cannot carry modern load. Undersized cables, no earthing, an inadequate distribution board, joints buried in walls. In a home from the 1980s or earlier, full rewiring is the honest answer, not a patch.
Plumbing at the end of its life. GI pipes corrode from the inside; by thirty years they are running at a fraction of their bore. If your pressure has quietly dropped over the years, this is why. Replace in CPVC or PPR while the walls are open.
Failed waterproofing. Bathrooms and terraces are the usual culprits. Signs are damp patches on the ceiling below or salt bloom at skirting level. Fixing it properly means stripping the bathroom floor back and relaying — there is no surface cure.
Uneven floors and out-of-plumb walls. Older construction was not built to modern tolerances. Large-format tile and slab stone expose this immediately. Levelling screed adds cost and height; find out early.
Structure you cannot move. The wall you planned to remove turns out to be load-bearing. Always get a structural opinion before finalising a layout on an older building.
Budget a genuine contingency on any renovation — and a larger one on a house over thirty years old. You will use it, and a project with a contingency is calm where one without it is a series of difficult conversations.
The sequence that works
A renovation done in the wrong order costs money twice.
- Survey and investigation — measure accurately, open up a small area if needed, get structural and services assessed
- Design and decide — resolve the whole scheme before anything is demolished
- Approvals — RWA or society NOC, and MCD or authority sanction if the envelope changes
- Demolition and disposal
- Structural work, if any
- Services first fix — plumbing, electrical, AC, data
- Waterproofing and curing — do not compress this
- Plaster, flooring, ceiling
- Joinery installation
- Paint and polish
- Second fix and fittings
- Snagging, then furniture and styling
The temptation is always to start demolition while the design is still settling, because it feels like progress. It is the most expensive thing you can do.
Living in it, or moving out
People ask this constantly. Honest answer: for anything beyond a cosmetic refresh, move out. Dust from demolition and stone cutting reaches every room regardless of sheeting. Water and power go off unpredictably. Work slows by 30 to 50 per cent when trades have to tidy up and vacate each evening.
If you must stay, phase it — do one floor or one zone completely, seal it, move into it, then do the rest. It takes longer overall but is liveable.
Where the money is best spent
Everything hidden. Wiring, plumbing, waterproofing. Unglamorous, and the only parts you genuinely cannot redo later without undoing the visible work.
The plan. The chance to change how the house works comes once. Spend design time here before spending money anywhere else.
Natural light. A new or enlarged opening, a glazed internal partition, a lighter floor in a dark room — these change daily life more than material upgrades do.
Where to hold back: imported stone in rooms nobody sees, automation beyond what you will use, and replacing things that are working fine because everything else is new.
Getting it right
Renovation rewards investigation and punishes optimism. The projects that run well are the ones where somebody looked properly before anyone picked up a hammer.
