With Diwali in November, whether your flat is ready in time depends almost entirely on which week you start and whether the bathrooms are in scope. Here is the arithmetic, done honestly.
Every September the same enquiry arrives, phrased the same way: can it be done before Diwali? The answer is genuinely yes or genuinely no depending on scope, and the difference between the two is worth knowing in September rather than discovering in the last week of October, with the flat open and the family arriving.
The way to answer it is to count backwards from the date, because the parts of a renovation that cannot be compressed are fixed no matter how much labour is thrown at them.
The times that do not compress
- Waterproofing has to cure, then be flood-tested and held before anything covers it. Skipping the test to save two days is how a bathroom leaks for the next decade.
- Screed and tile bedding need curing time before the floor takes load and before grouting.
- POP needs to dry through before it can be finished, and it dries slowly in humid weather.
- Putty and paint are coat-and-wait, repeatedly. Rushing the interval between coats is visible in the finish afterwards.
- A kitchen counter has a lead time - template, fabrication, delivery, installation - and the template can only be taken once the units are actually in place.
- Any imported or non-stock tile, sanitaryware or hardware carries a supply lead time that has nothing to do with your site.
- Society permission takes its own two to four weeks and has to happen before, not during.
What fits in roughly eight weeks
Starting in the first half of September, on a flat where the plumbing is left where it is, this is a realistic scope:
- Full painting, including putty and repair of existing surfaces
- POP or gypsum false ceiling with cornices and light points
- Electrical rewiring and additional points, with new switch plates and fittings
- Flooring replaced in dry areas
- Kitchen shutters, counter and dado replaced, with the plumbing points left in place
- Door and hardware replacement, polishing and minor carpentry
What does not fit, and should not be attempted
Twelve weeks or more, honestly stated:
- Bathrooms stripped back to the slab, with new waterproofing, a flood test, new falls, dado and fittings
- Any relocation of a bathroom or kitchen, which brings new drainage and a society approval process with it
- A full gut renovation of the whole flat, where every trade has to queue behind the one before it
- Anything structural, which needs a structural engineer and approvals before it needs a mason
A bathroom rushed to hit a date is the worst possible trade, because the corner that gets cut is nearly always the waterproofing test - the one part of the job that is invisible when done right and ruinous when skipped.
Decide the materials now, not later
In our experience the most common cause of a missed festive deadline is not labour and not the contractor. It is a decision that was still open when the crew was ready. Four choices are worth locking before work starts: floor and wall tile including the shade lot, sanitaryware and CP fittings, the kitchen counter material, and the paint shades. Everything downstream waits on those four, and a fortnight spent visiting showrooms mid-project costs a fortnight of site time.
The festival week itself
There is one more piece of arithmetic that catches people out. A large part of Mumbai's site labour travels home around the festival, and the crews thin out for the days before and often for a week or two afterwards. A programme that assumes full manpower right up to the day before is a programme that will not hold. Build the break into the plan rather than being surprised by it.
If you are starting in October, do it afterwards
This is unpopular advice and it is still the right advice. November through February is the best renovation window Mumbai has: the humidity is down so paint and POP behave, labour is back and available, and nothing is being rushed against a date. A renovation started calmly in November finishes better than the same renovation forced into six weeks - and it will still be finished long before anyone visits again.
