Interior work involves several trades: masons, electricians, plumbers, ceiling installers, painters and carpenters. Done in the wrong order, they undo each other's work: wiring chased into a painted wall, a ceiling cut open for a missed light, a new wardrobe splashed with paint. This guide sets out the usual order, and what tends to hold a project up.
In short: first fix the flat's defects and finalise the design. Then do the civil work, the concealed wiring and plumbing, the false ceiling and the first coats of paint. Then come the carpentry and installation, the fittings, the final coat of paint and the cleaning. Most delays come from late decisions, changes after work starts, and approvals.
Before any work starts
- Fix the builder's defects. Seepage, cracks and plumbing leaks should be repaired first; see our possession checklist.
- Get the society's permission. Most societies in Noida, Greater Noida and Ghaziabad ask for an application, a deposit and a worker list. See our society permission guide.
- Finalise the design and quote. Every point that's decided now (light positions, appliance sizes, the sink) saves cutting and rework later.
The usual order of work
| Step | Work | Why it comes here |
|---|---|---|
| 1 | Civil work: breaking or building walls, re-tiling, waterproofing | It's the messiest work and affects everything after it |
| 2 | Concealed electrical and plumbing: new points, conduits, pipes | Wiring and pipes go into walls and above ceilings before they're closed and painted |
| 3 | False ceiling | It closes over the wiring, so the light, fan and AC positions must already be fixed |
| 4 | Wall preparation and first coats of paint: putty, primer, first coat | Done before the carpentry arrives, so the finished furniture isn't splashed |
| 5 | Carpentry and installation: kitchen, wardrobes, TV unit | Made to measure and installed once the walls and ceiling are ready |
| 6 | Fittings: switch plates, lights, taps, appliances, hardware | Fitted once the surfaces around them are finished |
| 7 | Final coat of paint and touch-ups | Covers the marks left by installation |
| 8 | Deep cleaning and handover check | You inspect the finished home before the final payment |
Every flat is different, and some steps overlap. For example, modular cabinets are made in a workshop while the site work is going on, which saves time.
Tips that save rework
- Plan the electrical points with the furniture layout. Plug points behind the bed, inside wardrobes for lights, at the TV unit and for every kitchen appliance.
- Test the plumbing before the walls are closed. A leak found after painting means breaking a finished wall.
- Leave access panels in the false ceiling where junctions, AC units or pipes sit above it. See our false ceiling guide.
- Protect what's finished. Cover floors and finished cabinets while other trades work.
What usually causes delays
- Late decisions: a shutter colour, a hob model or a light fitting that isn't chosen holds up the trades waiting for it.
- Changes after work starts: moving a point or resizing a cabinet means redoing finished work.
- Approvals and access: society permissions, work hours, lift bookings and delivery timings.
- Builder defects found late: seepage behind a new wardrobe means removing it to repair the wall.
- Material availability: specific finishes or imported fittings can take longer to arrive.
The best protection is a design and quote that are complete before work starts, with a timeline you've agreed.
Frequently asked questions
Should painting be done before or after carpentry?
Both. The putty, primer and first coat come before the carpentry, and the final coat after installation, to cover marks.
Should the false ceiling go in before or after wiring?
After. The wiring, light positions and AC pipes are fixed first, then the ceiling closes over them.
How long do 2BHK or 3BHK interiors take?
It depends on the scope, the materials and the society's rules, so ask for a timeline with your quote. Decisions made early, and few changes once work starts, keep it on track.
Who coordinates all the trades?
With a design-and-build firm, the firm does. If you hire separately, you or your designer coordinate them. Our guide on how interior designers charge explains the difference.
