Sandstone Floor Cleaning Sandstone and Slate Floor Cleaning in Delhi NCR
These stones are cleaned by controlled scrubbing and then protected with an impregnating sealer. Polishing them is usually wrong, because the whole point of the finish is the natural matte texture. Delhi NCR mixes very old housing stock with new high-rise towers, so a single visit can mean Kota stone in one room and Italian marble in the next. We carry pads for both and quote each surface on its own merit.

Sandstone Floor Cleaning rates in Delhi NCR
| Work | Guide band | Notes |
|---|---|---|
| Deep cleaning | Rs 5-15 per sq ft | Sandstone, slate, Kota |
| Deep clean and de-scale | Rs 15-25 per sq ft | Efflorescence present |
| Cleaning with sealer | Rs 15-25 per sq ft | Recommended finish |
| Re-sealing cycle | Quoted after inspection | 12-24 months |
Rates depend on surface type, damage depth, area and access. The figure is written down before work begins.
Reading a per sq ft quote correctly
- Ask whether grinding is included or quoted separately, because that is the single biggest swing in the number
- Ask what the rate excludes: coatings, crack filling, slab replacement and waste removal are the usual extras
- Check whether the area is charged on carpet area or built-up area, and whether staircases are priced per step
- Confirm the rate applies to the measured floor, not an estimate from photographs
- Insist on one written figure per surface where floors are mixed
| Rate band | Typical work included |
|---|---|
| Lowest band | Maintenance buff on a sound floor |
| Middle band | Diamond polishing, scratch and lane correction |
| Upper band | Grinding, deep correction, crystallisation or coating |
Two quotes can differ by 40 percent for the same floor simply because one includes grinding and the other does not. Compare the scope, not just the number.
Dust and water control is planned before we start: masking on skirting and fittings, wet working instead of dry, and slurry vacuumed as the machine moves rather than left to dry in corners.
Old polish, wax and cleaning residue are stripped before any new finish goes on. Layering a fresh treatment over residue is what makes floors look grey again within weeks.

Sandstone Floor Cleaning - common questions
What are the white patches on my sandstone or slate?
Efflorescence, mineral salts pushed to the surface by moisture. It is removed with a pH-neutral treatment, and the underlying damp should be addressed or it returns.
Can slate be sealed outdoors?
Yes, with an impregnating sealer, and it will need re-sealing every twelve to twenty-four months depending on rain and foot traffic.
Is pressure washing safe?
On soft sandstone it is not, because it erodes the surface and drives water into the layers. Controlled low-pressure cleaning with the right brushes is safer.
Should sandstone be polished?
Usually not. Sandstone reads best with its natural matte finish, and polishing it only makes the surface unevenly reflective. Where a smoother finish is wanted, honing is the right process.
Why do per sq ft rates differ so much between contractors?
Almost always scope. A rate that excludes grinding, crack filling and coatings looks cheaper until those are added. Ask for the scope in writing and compare the total, not the headline rate.
Is the rate cheaper for larger areas?
Yes. Above roughly 1,000 sq ft we move to slab rates because setup and travel are spread over more work.
How do you measure the area?
On site, with you present, room by room. You see the measurement sheet before the quote is finalised.
