| Scope | Partial renovation | Full redo |
|---|---|---|
| Demolition and disposal | ₹35,000 | ₹1,60,000 |
| Joinery | ₹2,60,000 refaced | ₹7,20,000 new |
| Kitchen | ₹1,40,000 shutters and counter | ₹4,20,000 new |
| Flooring | ₹1,20,000 overlay | ₹2,60,000 with demolition |
| Electrical and lighting | ₹95,000 | ₹2,40,000 |
| False ceiling and painting | ₹1,25,000 | ₹2,10,000 |
| Total, ex-GST | ₹7,75,000 | ₹20,10,000 |
| Programme | 6 – 8 weeks | 12 – 20 weeks |
The renovation route is roughly 38% of the redo cost and less than half the programme — provided the carcasses are genuinely sound.
How to judge whether the carcass is worth keeping
- Identify the board. Look at a cut edge inside a cabinet. Plywood shows layers; MDF is uniform brown; particle board shows visible chips. Particle board and MDF carcasses in a Mumbai kitchen are usually not worth keeping past year eight.
- Check the bottom rails. Press the bottom rail of the sink base unit and the wardrobe. Any sponginess means the board has absorbed water and the unit should go.
- Check squareness. Open and close every shutter. Doors that bind or have uneven gaps usually indicate a carcass that has moved.
- Check the fixings. Wobble the shelves and the hanging rails. Stripped screw holes in a fibreboard carcass cannot be reliably repaired.
- Smell the inside. A musty smell in a closed wardrobe means moisture has been present for a long time, and refinishing the outside will not address it.
What forces a full redo
- A layout that does not work. No amount of refinishing fixes a kitchen in the wrong place or a bedroom you cannot get a wardrobe into.
- Inadequate electrical capacity. An older Mumbai flat wired for two fans and a fridge will not carry three air conditioners, a geyser, an oven and an induction hob. The distribution board, the circuits and often the incoming cable have to be replaced, and that means chasing every wall.
- Failed waterproofing. A bathroom leaking into the flat below has to be opened to the slab. There is no partial version of this.
- Plumbing that needs to move. Most societies restrict changes to drain positions, and where a change is allowed it means breaking the floor.
- Carcasses in particle board or swollen MDF. Refacing a failing carcass is money spent on something that will be removed within three years.
Living in the flat while it happens
A partial renovation can often be phased so the family stays; a full redo usually cannot. That decision has a cost of its own and it belongs in the comparison.
- Phasing a renovation room by room adds roughly 15–20% to the labour cost, because the gang is set up and struck down repeatedly, and it extends the programme by two to three weeks.
- Against that, three months of alternative accommodation in Mumbai is a significant number, and so is the disruption of moving twice.
- Wet trades are the constraint. Tiling, plumbing and POP cannot be phased comfortably around an occupied kitchen or bathroom.
- Dust is the other constraint. Board cutting and demolition in an occupied flat needs sealed doorways, daily cleaning and a tolerant household.
- Our usual advice: phase a partial renovation, vacate for a full redo. Trying to live through a twelve-week strip-out is where most family disputes about interiors begin.
Verdict
| Condition of the flat | Route |
|---|---|
| Layout fine, BWP carcasses sound, services adequate | Renovate — shutters, counters, lighting, paint |
| Layout fine, carcasses in MDF or particle board | Redo the joinery; keep the flooring and services |
| Layout wrong or storage inadequate | Full redo |
| Electrical capacity inadequate | Full redo, or at minimum a full rewire |
| Bathroom leaking to the flat below | Full strip of that bathroom regardless of the rest |
| Flat bought for resale in three years | Renovate — finishes and lighting only |
| Redevelopment flat, developer finishes | Usually a redo of joinery, renovate the rest |
What we do at the survey: open every cabinet, press every bottom rail, check the distribution board and read the electricity bill for the sanctioned load. Those four checks decide the route, and they take an hour. Deciding by budget first, and discovering the carcass is rotten in week three, is how renovations become redos at twice the price.
Frequently asked questions
How much cheaper is renovating than redoing?+
Roughly a third to 40% of the cost, and less than half the programme, on a 650 sq ft flat. That only holds if the carcasses are sound. Refacing a failing carcass costs the same and buys three years instead of eighteen.
Can I change shutters without changing the carcass?+
Yes, and it is the highest-value renovation available. New shutters, new handles, a new counter and new lighting transform a kitchen for roughly a third of a replacement, provided the carcass is BWP plywood, square and dry.
Can new flooring go over the existing floor?+
SPC and thin porcelain can, which saves the demolition, the debris and about two weeks. You do raise the floor level at thresholds and you inherit whatever is underneath, so it works best where the existing floor is sound and flat.
When is a full rewire unavoidable?+
When the connected load has outgrown the original design — multiple air conditioners, a geyser, an oven and an induction hob in a flat wired decades ago. Check the distribution board and the sanctioned load on your bill. If there is no earth leakage protection, that alone justifies the work.
How long does each take in an occupied flat?+
Six to eight weeks for a partial renovation and twelve to twenty for a full redo, both assuming society working hours of roughly 10am to 6pm on weekdays. Most families vacate for a full redo; a partial renovation can often be phased room by room.
