Renovating an older house in NIT or Ballabgarh means fixing what's behind the walls before anything goes on them: waterproofing, wiring and plumbing come first, interiors second. Waterproofing alone runs ₹60–250 per sq ft for a terrace and ₹40–120 per sq ft for a bathroom (Asian Paints). Skip that step and a new wardrobe or false ceiling can be ruined by the first monsoon. This guide covers the order of work, the costs to budget for, and when rebuilding makes more sense than renovating.

Key Takeaways

  • In an older house, budget for waterproofing, rewiring and plumbing before any interior finishes.
  • Waterproofing costs ₹60–250 per sq ft for terraces, ₹40–120 for bathrooms and ₹35–100 for external walls (Asian Paints).
  • A kitchen remodel alone runs about ₹0.5–3.5 lakh, depending on the grade.
  • If the structure itself is failing, compare the renovation quote with a rebuild at ₹1,350–2,700 per sq ft for the structure alone.

Why Are Old Houses in NIT and Ballabgarh Different?

Much of NIT was planned from 1949 to house families displaced by Partition, and many of its houses and those in older Ballabgarh have been extended floor by floor over decades. That history shows up in renovation budgets. The wiring was sized for fans and bulbs rather than ACs and induction hobs; plumbing may be galvanised iron that has corroded inside; and terraces have often been re-laid several times without proper waterproofing.

A new society flat usually needs interior work only. An old house usually needs civil work first, and that's priced separately from the interior. Treat any quote that goes straight to wardrobes and ceilings without asking about the terrace, wiring and pipes as incomplete.

What Should Be Fixed Before the Interiors?

Terrace waterproofing costs ₹60–250 per sq ft and bathroom waterproofing ₹40–120 per sq ft, depending on whether a basic cementitious system or a premium polyurethane coating is used (Asian Paints). Waterproofing is the first job, because every other finish depends on the walls and ceilings staying dry.

AreaRate per sq ftWhen it's needed
Terrace₹60–250Damp patches or peeling paint on the top-floor ceiling
Bathroom₹40–120Seepage on the wall behind or the ceiling below
External wall₹35–100Damp inside walls after rain, efflorescence
Basement₹120–300Any below-ground room

Rewiring comes next. Electrical work is usually priced per point — a light, fan, socket or AC point — with each rate covering the wire, conduit, switch and labour (Studio Matrx). Rewiring an old home costs more per point than wiring a new one, because finished walls have to be cut and made good. If the house still has old aluminium wiring, no earthing, or a fuse box instead of MCBs, replace it before you plan any new lighting.

Plumbing is the third check. Old galvanised pipes can look fine outside and be half-blocked inside. Low pressure at the taps is the giveaway. Replacing pipes before you tile a bathroom costs far less than breaking new tiles later.

The single most useful thing to do before getting renovation quotes is to live through one monsoon in the house, or talk to someone who has. Mark every damp patch on a floor plan. That map tells your contractor exactly where to waterproof, and stops you paying for a whole-terrace job when one parapet is the problem.

How Much Does It Cost to Renovate the Kitchen and Bathrooms?

A kitchen remodel runs about ₹0.5–3.5 lakh depending on size, materials and customisation. In an old house, add the civil work first: moving the sink or hob often means new plumbing and electrical lines, and an old kitchen slab may need to be broken out.

Bathrooms follow the same rule. Waterproof the floor and the lower walls before retiling, check the slope to the drain, and replace the supply pipes while the walls are open. The waterproofing is cheap relative to the tiles and fittings, and it's the part you can't redo without breaking everything.

Should You Renovate or Rebuild?

New construction of the structure in Faridabad typically costs ₹1,350–2,700 per sq ft, depending on the area and steel brand, and the same pricing applies near Ballabgarh. When a renovation quote starts approaching those numbers, it's time to price a rebuild too.

Consider rebuilding when:

  • The structure has cracks in beams or columns, not just plaster
  • The house has been extended floor by floor on foundations never designed for it
  • Almost every service — wiring, plumbing, waterproofing — needs replacing anyway
  • The layout doesn't work, and fixing it means moving load-bearing walls

A rebuild needs a new building plan approved by HSVP for HSVP-sector plots, or by the Municipal Corporation of Faridabad within its limits. Structural changes during a renovation may need approval too. Our house construction cost guide for Faridabad has per-sq-ft rates and worked examples by home size. If the structure is sound and you'd rather build up than rebuild, read the first floor construction cost guide first, and the terrace waterproofing cost guide compares roof systems by method.

In our experience, the renovations that go over budget are almost always the ones that started with the interiors and discovered the civil problems halfway through. The ones that stay on budget opened the walls, fixed the services, and only then designed the finishes.

In What Order Should an Old-House Renovation Happen?

  1. Survey: structure, damp map, wiring, plumbing, and what's worth keeping.
  2. Structural repairs, with an engineer if cracks are more than cosmetic.
  3. Waterproofing: terrace, bathrooms, external walls.
  4. Services: rewiring, new plumbing, drainage.
  5. Plaster and flooring repairs.
  6. Interiors: false ceiling, carpentry, kitchen, wardrobes.
  7. Painting, fittings and handover.

Who should run it? For an old house, you need both a designer and a civil contractor, or a single turnkey firm that does both. Our guide to interior designer vs decorator vs contractor explains who does what. For the interior side of the budget, see the interior design cost guide for Faridabad.
