Old flat renovation in Noida — before and after transformations
10-20 year old flats in Noida need more than paint. Plumbing has corroded, electrical wiring is undersized, bathroom waterproofing is failing, modular furniture is worn out. Aarna Constructions has renovated old flats in Noida since 2017, with full re-plumbing, rewiring, new modular, and structural modifications where needed.
Common issues in 10+ year old Noida flats
- Plumbing corrosion: galvanised iron pipes from the era rust; joints leak slowly; water pressure drops
- Electrical undersized: original 1KW-2KW sanction cannot handle modern AC + geyser + microwave + washing machine
- Bathroom waterproofing failure: sunken-floor waterproofing typically fails 8-12 years; leaks to flat below inevitable
- Tile debonding: hollow sound when tapped; loose tiles cracking underfoot
- Kitchen modular worn: 10-year-old carcass has shutter issues, hardware failures, chimney capacity inadequate
- Paint moisture damage: walls behind wardrobes / on external-facing sides show damp, efflorescence
- Doors / windows: wooden doors warp; aluminium windows leak air and noise
- Flooring: marble polish gone dull; vitrified tiles crack lines; wooden flooring swollen at joints
- Electrical fittings: old switches fail; MCB board undersized
- False ceiling: POP sagging; junctions cracked

Window frames (steel)
Old steel windows rust + lose alignment. Replace with powder-coated aluminium. Rs 8-15k per window.
Bathroom waterproofing
Old waterproofing membrane fails after 8-10 years. Strip to slab + redo. Mandatory for warranty.

Old flush doors swell + warp. Replace with HDF doors. Rs 4-8k per door installed.

Frequently asked
Is renovating an old Noida flat worth it vs buying new?
Usually yes — old Noida flats (Sec 18-50) are in established neighbourhoods with mature trees, schools, markets within walking distance. Renovation Rs 8-18L vs Rs 40-90L premium for similar-spec new construction.
How do I know if my old flat has structural issues?
Check: ceiling cracks (hairline = OK, wider than 2mm = structural), water seepage from above (waterproofing failure on upper floor), wall plumb (use a level — walls leaning >5mm need investigation). Structural engineer site visit costs Rs 3-5k.
Does old flat renovation need society NOC?
Yes, in all Noida societies. Old societies (Sec 18-50) often have stricter restrictions on work hours + material delivery. We coordinate with RWA on day 1.
What surprises usually emerge during old flat renovation?
Top three: hidden water damage behind tiles, corroded electrical conduits, and unauthorised previous-owner alterations affecting structure. We allow 8-12% contingency for these.
